Published: September 22, 2025 | Latest Update: October 5, 2026
An EZGO golf cart charger is matched to the cart's battery system, and E-Z-GO now builds five: a 36 volt unit, a 48 volt lead acid unit, two 48 volt lithium units, and a 51 volt lithium unit for the newest Samsung SDI packs.
The light flashes a pattern you cannot decode, and the pack is no fuller in the morning.
A cart that charged for years refuses to start a cycle.
A lithium conversion arrives, and the old Delta Q ignores it.
Every missed cycle shortens the life of a pack that costs more than the charger.
Charger confusion usually comes down to three things:
- Voltage, since EZGO carts ship as 36V, 48V, and 51V systems and the chargers do not interchange.
- Plug type, since the D plug, the triangular plug, and the lithium plugs differ for a reason.
- Fault codes, since a flashing red light means something specific and the manual is usually gone.
Carts & Parts stocks every current OEM EZGO charger and matches it to your serial number. The guide below covers how to use an EZGO golf cart charger, read its fault codes, and pick the OEM charger that fits.
Key Takeaways
Which EZGO golf cart charger do I need?
The right EZGO charger depends on battery voltage and plug type. 36V lead acid carts with a D plug use the Lester Summit II PN# 672620, 48V lead acid carts with the triangular plug use the Delta Q SC-48 PN# 635671, 48V ELiTE lithium carts use the Delta Q QuiQ Gen2 PN# 10004916 or PN# 10009053G04, and 51V Samsung SDI lithium carts use the Gen2 51V PN# 10004924.
How do I charge an EZGO golf cart correctly?
Park on a level surface, turn the key off, plug the DC cord into the cart receptacle first and the AC cord into a grounded outlet second, then let the charger run through all three stages until the green light shows full. A 48V Delta Q needs at least 30 volts present in the pack before it will start a cycle.
What do EZGO charger fault codes mean?
Delta Q chargers signal faults with a red LED blink count. One flash means high battery voltage, two means low battery voltage, three means charge timeout, four means the batteries could not be trickle charged, five means over temperature, and six means an internal charger fault. Most codes clear once connections are cleaned and the pack reads above 30 volts.
Can I use a lead acid charger on a lithium EZGO?
A lead acid charger cannot be used on an EZGO ELiTE lithium cart, because ELiTE packs need a charger that communicates with the Samsung SDI battery management system, which the lead acid SC-48 cannot do. Use the 48V QuiQ Gen2 PN# 10004916 on 48V ELiTE carts and the 51V Gen2 PN# 10004924 on 51V systems, and confirm the version from your serial number.
How Does the EZGO Golf Cart Charging System Work?
The EZGO charging system on a TXT, RXV, Express, or Freedom electric cart pairs an external or on board charger with a receptacle wired straight to the battery pack, and the charger reads pack voltage before it sends a single amp.
A Delta Q or Lester charger moves through three stages. Bulk delivers full current to roughly 80 percent, absorption tapers current while holding voltage to top off each cell, and maintenance keeps the pack full without boiling electrolyte.
Lithium systems add a fourth participant. The Samsung SDI battery management system tells the Gen2 charger what the pack will accept, and the charger will not start without that handshake. Knowing how your EZGO golf cart parts work together makes every charging problem easier to trace.
Why does the right charger matter for battery life?
The correct charger holds peak voltage to the battery chemistry, roughly 57 to 59 volts on a 48V flooded pack, while generic units drift high or low. Too low leaves plates sulfated, too high boils water out of the cells, and either one takes years off the pack.
Temperature compensation matters as much. A Delta Q trims voltage on a hot day and raises it in the cold, which is why your EZGO golf cart batteries last longer on the charger they were designed around.
What does the state of charge gauge tell you?
Electric EZGO carts show pack condition on the dash state of charge meter, which reads voltage, not amp hours, so a full pack under load can dip and recover. Gas carts carry a fuel gauge in that spot instead, and our EZGO fuel system guide covers that side of the lineup.
How Do You Charge an EZGO Golf Cart Step by Step?
Charging an EZGO with any Delta Q, Lester, or Gen2 charger follows the same order, and getting the sequence right prevents the arcing that burns receptacle pins over time.
- Park on level ground, turn the key off, and set the run/tow switch to tow on carts that have one.
- Inspect the receptacle and plug for green corrosion or scorched pins before connecting anything.
- Plug the DC cord into the cart first, then the AC cord into a grounded 110 volt outlet.
- Watch for the LED to begin its charging pattern within about ten seconds.
- Let the cycle finish on its own; the green light means the charger has entered maintenance mode.
- Unplug the AC cord first, then the DC cord, and close the receptacle cover.
Charge flooded lead acid packs after every day of use and check water levels after charging, never before. Lithium packs can be topped off at any state of charge.
💡 Tip: Leaving a Delta Q plugged in between uses is safe. Maintenance mode supplies only enough current to offset self discharge, and the charger shuts down if the pack voltage rises past its set point.
What Do the LED Lights and Fault Codes on an EZGO Charger Mean?
Delta Q SC-48 and QuiQ chargers report status through a yellow charging LED, a green full LED, and a red fault LED that blinks a count. Reading the pattern takes the guesswork out of a cart that will not charge.
| LED | Status | What It Means |
|---|---|---|
| Flashing yellow | Preparing to charge | Charger is reading pack voltage before starting. |
| Solid yellow | Charging | Bulk stage, full current to about 80 percent. |
| Flashing green | Nearly charged | Absorption stage, current tapering to top off cells. |
| Solid green | Fully charged | Maintenance mode, pack is full and being held there. |
| Red blinking | Fault | Count the flashes and see the fault code table below. |
Source: Delta Q SC-48 and QuiQ charger documentation. Patterns vary slightly by model; confirm against your charger manual.
The red fault LED uses a blink count rather than a steady light. Count the flashes between pauses.
| Flashes | Fault | Where to Look First |
|---|---|---|
| 1 | High battery voltage | Wrong voltage charger for the pack, or a 36V pack on a 48V charger. |
| 2 | Low battery voltage | Pack under 30 volts, dead battery in the string, or loose cable. |
| 3 | Charge timeout | Pack did not reach full in the allowed time; bad cell or sulfated plates. |
| 4 | Battery could not be trickle charged | Corroded terminals, loose connections, or a battery that will not hold voltage. |
| 5 | Over temperature | Charger too hot; improve airflow and let it cool before retrying. |
| 6 | Internal charger fault | Reset once; if the code returns, the charger needs service or replacement. |
Source: Delta Q Technologies QuiQ fault code reference. Codes 1 to 5 point at the pack and connections before the charger.
Codes one, two, and four trace to the pack or its connections. Code five clears when the unit cools. Code six is the only one that points at the charger itself.
⚠️ Warning: A pack reading under 30 volts total will not wake a Delta Q at all. No lights is not a fault code; it is the charger refusing to start on a pack it cannot read.
If the lights stay dark with the pack above 30 volts and the outlet confirmed live, our guide on testing a golf cart charger walks through checking output at the plug.
Can I reset an EZGO charger?
Resetting an EZGO charger takes about a minute. Unplug both cords, wait 30 seconds for the capacitors to discharge, and reconnect in the DC first, AC second order. Stored fault codes clear on power up, and a code that returns immediately is telling you the fault is still present. Our golf cart charger reset guide covers the sequence for each charger family.
Which OEM EZGO Charger Fits a 48 Volt Lead Acid Cart?
The OEM EZGO 48 Volt 13 Amp Charger PN# 635671 is the Delta Q SC-48, built for 48V lead acid RXV, TXT, Valor, Freedom, and Express carts that use the triangular 3 pin receptacle.
The OEM EZGO Golf Cart Charger 48 Volt 13 AMP PN# 635671 delivers 13 amps through a sealed IP66 die cast housing, runs a flooded lead acid profile with temperature compensation, and shuts off automatically at full charge. Fitment covers RXV 2008 to 2023, TXT 48V 2010 to 2022, Valor 48V, and Express S4 and L4 48V variants.
Thirteen amps fills a depleted pack overnight in roughly eight to ten hours, and it is the rate E-Z-GO shipped with the cart.
Laura Roberts found out what dealer support looks like when her charger and batteries were both in question:
"I couldn't believe how easy it was to get help for free. They took their time with me and went above and beyond what I ever expected. I feel like I should have paid them. They resolved the battery and charger issues for my golf cart right then and there. I couldn't even get help from the place where I bought the charger. Thank you guys so very much!"
Reviews like hers are part of the more than 2,000 online reviews Carts & Parts has earned by diagnosing the charging system instead of guessing at it.
Which Charger Fits a 36 Volt EZGO TXT or Medalist?
The EZGO Lester Summit II 36V Off Board Charger PN# 672620 replaces the original PowerWise charger on 36V Medalist 1994 to 1999, TXT 1996 to 2009, Workhorse 800 and 1000, ST Sport, and Shuttle 950 carts equipped with the D plug.
The EZGO Lester Summit II 36V Off Board Charger PN# 672620 outputs 18 amps at 650 watts, is factory preset for deep cycle lead acid, and adds Bluetooth monitoring through the Lester app so you can check cycle status from the house. It replaces older part numbers 602718, 611118, 611119, 612492, 632482, and PF10820.
Count the batteries before ordering. Six 6 volt batteries make a 36V pack, and the D shaped plug confirms it. A triangular plug on a cart labeled 36V means a previous owner converted it to 48V.
⚠️ Important: A 48V charger on a 36V pack boils the electrolyte and warps plates within a single cycle. A 36V charger on a 48V pack never reaches full charge and sulfates the plates over weeks. Match the voltage before anything else.
Scott Amburn went through the voltage check and plug check with the counter staff before buying:
"Just went and bought a smart charger from here. Great price, and service was excellent. They were super busy but treated me like I was their most valuable customer. I believe it was Cole who helped me. He answered all my questions and didn't try to rush through them. I appreciate that. Anything I ever need for my cart will definitely be purchased here."
Which Charger Fits a 48 Volt ELiTE Lithium EZGO?
EZGO ELiTE lithium carts with 48V Samsung SDI packs use a Delta Q QuiQ Gen2 charger programmed to communicate with the battery management system, and E-Z-GO sells it two ways.
The OEM EZGO Golf Cart Lithium Charger 48 Volt Delta Q QuiQ 810W PN# 10004916 is the charger unit alone, for owners whose existing cord and plug are in good shape. It carries a 110 volt US input and the lithium algorithm the ELiTE pack requires.
The OEM EZGO Golf Cart Gen2 Charger with 3 Meter Cord PN# 10009053G04 is the same Gen2 platform supplied with its DC cord attached, which is the right choice when the old cord is cut, scorched, or missing. It supersedes the earlier 10009053G03.
Paul Poeppelman had his cart converted to 48V lithium at the shop and described the parts side:
"If you are looking for a new golf cart, this is tge place to go! Great prices, very friendly and knowledgeable service!! I had a 48 volt lithium ion conversion done on my cart, parts were in stock and ready to be installed the day I dropped it off. The parts were of good quality, and reputable companies. 100% pleased with the whole interaction. Will definitely go back for my future golf cart needs."
Which Charger Fits a 51 Volt EZGO Lithium Cart?
The newest EZGO and Cushman lithium carts run a 51 volt Samsung SDI system, and the OEM EZGO 51 Volt Battery Charger PN# 10004924 is the Gen2 unit built for it, supplied with a 5.5 meter cord.
The OEM EZGO Golf Cart 51 Volt Battery Charger PN# 10004924 is a direct replacement for the factory installed charger on 51V carts and is not interchangeable with the 48V Gen2, even though the housings look alike. The plug and the BMS handshake both differ.
51V systems also use their own receptacle. Our EZGO golf cart charger receptacle guide explains how to tell the 48V lead acid, 48V lithium, and 51V lithium ports apart before you order either part.
✅ Good to Know: The serial number plate settles the 48V versus 51V question in seconds. Text it to (937) 459-8891 and we will confirm which Gen2 charger and receptacle your cart left the factory with.
Which Charger Fits a 48 Volt EZGO 2Five LSV?
The EZGO 2Five street legal LSV carries its charger on board, and the OEM EZGO 48V On Board Charger with DC-DC Converter PN# 632862 combines the pack charger with the converter that feeds the 12 volt lighting and accessory circuit.
The OEM EZGO Golf Cart 48V On Board Charger with DC-DC Converter PN# 632862 fits 2016 to 2020 2Five 48V models directly. 2010 to 2015 2Five carts need adapter 641860 to convert the two plug harness to the three pigtail layout.
A pack that will not charge and headlights that dim at the same time usually mean the combined unit has failed, since one housing handles both jobs.
How Do You Choose the Right EZGO Charger in Four Steps?
Choosing an EZGO charger comes down to voltage, plug type, battery chemistry, and amperage, checked in that order.
- Verify voltage. Count batteries and multiply: six 6V = 36V, six 8V or four 12V = 48V. Lithium packs are labeled 48V or 51V on the pack itself.
- Confirm plug style. D shaped means 36V lead acid, triangular 3 pin means 48V lead acid, and the lithium plugs are specific to the ELiTE receptacles.
- Match chemistry. Lead acid carts take the SC-48 or Lester Summit II; ELiTE lithium carts take the 48V or 51V Gen2.
- Pick amperage. 13 amps for gentle overnight charging, 18 amps where turnaround matters.
| System | Plug | OEM Charger | Fits |
|---|---|---|---|
| 36V lead acid | D plug | Lester Summit II PN# 672620 | Medalist 1994 to 1999, TXT 1996 to 2009, Workhorse, ST Sport, Shuttle 950 |
| 48V lead acid | Triangular 3 pin | Delta Q SC-48 PN# 635671 | RXV 2008 to 2023, TXT 48V 2010 to 2022, Valor, Express S4 and L4 |
| 48V ELiTE lithium | ELiTE lithium plug | QuiQ Gen2 PN# 10004916 (charger) or PN# 10009053G04 (with cord) | ELiTE lithium RXV and TXT with 48V Samsung SDI pack |
| 51V ELiTE lithium | 51V lithium plug | Gen2 51V PN# 10004924 | Newest EZGO and Cushman lithium carts with 51V Samsung SDI pack |
| 48V 2Five LSV | On board, hardwired | On Board Charger with DC-DC PN# 632862 | 2Five 48V 2016 to 2020; 2010 to 2015 with adapter 641860 |

Why Choose an OEM EZGO Charger?
A genuine Delta Q or Lester unit from E-Z-GO carries the charging algorithm the pack was engineered around, while universal chargers run one profile meant to cover many different packs.
OEM Delta Q advantages include:
- Battery specific algorithms for flooded, AGM, gel, and lithium chemistries.
- Temperature compensation that adjusts voltage to ambient conditions.
- Sealed IP66 construction rated for outdoor storage.
- Manufacturer warranty backed by an authorized E-Z-GO dealer.
The difference shows up in battery life over seasons, not in the first month of use.
Why Is My EZGO Golf Cart Not Charging?
A 48V or 36V EZGO that will not charge almost always has a connection, voltage, or pack balance problem rather than a dead charger, and a four step check finds it in under an hour.
Symptom: No lights, no clicks, nothing.
Cause: Pack voltage under 30 volts, a dead outlet, or corroded receptacle pins.
What it means: Confirm the outlet, clean the pins, and measure pack voltage before touching the charger.
Symptom: The charger starts, the LED stays yellow for hours, and the pack never fills.
Cause: One battery far below the others, usually a bad cell.
What it means: Test each battery and charge the weak one on its own; our guide on how to charge golf cart batteries individually covers the method.
Symptom: The red LED blinks a steady count.
Cause: See the fault code table above.
What it means: Codes one through five point at the pack and connections, code six at the charger.
Symptom: Charges fine, dead by morning.
Cause: Parasitic draw or a battery that holds surface charge but no capacity.
What it means: Load test the pack, since the charger did its job.
Quick diagnostic checklist:
- Test the outlet with another device and check the breaker.
- Measure total pack voltage at the receptacle and confirm it is above 30 volts.
- Inspect every terminal for green corrosion, loose cables, or burnt connectors.
- Clean with a baking soda solution, tighten to spec, and retest.
A single corroded connection can drop charging voltage two to three volts, enough to stop a cycle entirely.
A pack that reads under 30 volts will not wake the charger at all, and our guide on how to charge a golf cart battery without a charger covers the safe ways to lift the weakest batteries until the charger takes over.
🚨 Warning: Lead acid batteries release hydrogen while charging. Charge in a ventilated space and follow OSHA standard 1917.157 on battery charging and changing.
What Happens If You Keep Using the Wrong Charger?
Running the wrong charger, or ignoring a charger fault, turns a replaceable charger into a replaceable battery pack.
- Undercharging lets lead sulfate crystals harden on the plates permanently.
- Overcharging boils electrolyte, warps plates, and releases explosive hydrogen gas.
- Uneven charging leaves one weak battery that drags down the whole pack.
- A lithium pack charged by a lead acid unit can trip the BMS into a lockout that only the dealer can clear.
According to OSHA standard 1926.441 on batteries and battery charging, proper ventilation and charging procedures prevent the hydrogen buildup that makes a battery compartment dangerous.
What Does a Properly Charged EZGO Look Like?
A correctly matched EZGO charger produces the same result every morning: a green light, a full pack, and a cart that holds speed on the last hill of the day the way it did on the first.
- The LED moves through yellow, flashing green, and solid green on a predictable schedule.
- Pack voltage reads within a tenth of a volt across every battery.
- Range per charge stays steady season to season instead of shrinking each month.
- The receptacle stays cool and the pins stay clean, because the plug sequence was right.

Frequently Asked Questions About EZGO Golf Cart Chargers
How long does an EZGO golf cart charger last?
Quality OEM Delta Q and Lester chargers typically last 5 to 7 years with proper care, and many run a decade. Sealed housings and clean receptacle pins are the two biggest factors we see in charger lifespan.
Can I leave my EZGO charger plugged in all the time?
Yes. Delta Q and Lester chargers drop into maintenance mode at full charge and supply only enough current to offset self discharge. Check water levels in flooded batteries monthly when a cart stays on the charger.
What do the fault codes on my EZGO charger mean?
Delta Q chargers blink the red LED in a count: one for high battery voltage, two for low voltage, three for charge timeout, four for a pack that cannot be trickle charged, five for over temperature, and six for an internal fault. Codes one through five point at the pack or connections first.
How do I charge an EZGO golf cart for the first time?
Turn the key off, plug the DC cord into the cart first and the AC cord second, and let the charger run a full cycle until the green light holds steady. Charge after every use on lead acid, and check water levels after charging rather than before.
Will my old 48V Delta Q charge a lithium conversion?
No. The SC-48 runs a lead acid profile and cannot communicate with a Samsung SDI battery management system. ELiTE lithium carts need the 48V Gen2 PN# 10004916 or 10009053G04, and 51V systems need the 51V Gen2 PN# 10004924.
How do I know if my charger or my batteries are bad?
Measure pack voltage at the receptacle first. A pack under 30 volts will not wake the charger and is a battery problem. A pack above 30 volts with no charger lights, confirmed outlet, and clean pins points to the charger.
What is the difference between 13 amp and 18 amp EZGO chargers?
Amperage sets charging speed. The 13 amp SC-48 fills a 48V pack overnight in about 8 to 10 hours. The 18 amp Lester Summit II and QuiQ units finish faster and suit carts that work more than one shift a day.
Can I use an RV converter or car charger on my EZGO?
Not across the whole pack. RV converters and car chargers are built for 12 volts and lack the multi stage algorithm a 36V or 48V pack needs. A car charger set to the matching voltage can charge one lead acid battery at a time in an emergency, with the pack disconnected.
Why does my EZGO charger get hot?
Warmth is normal during bulk charging. A housing too hot to touch means blocked airflow or a failing unit. Mount or set the charger where air moves on all sides and keep it off the floor of a closed shed in summer.
Do you ship EZGO chargers nationwide?
Yes. We ship OEM Delta Q, Lester, and Gen2 chargers anywhere in the country with free shipping on orders over $50.00. Send your serial number by text to (937) 459-8891 and we will confirm fitment before the order goes out.
