Best golf cart chargers by plug: Club Car, EZGO, Yamaha and lithium

If you want one golf cart charger that fits any cart you will own and any battery you will put in it, buy the Lester Summit Series II with the plug for your current cart. If you want to replace the charger that died with one that plugs straight in, buy by the receptacle on the side of your cart: a PowerWise D-plug unit for a 36V EZGO, a round three-pin unit for a Club Car, a notched three-pin for a TXT48 or RXV. If you have gone lithium, buy a charger with a lithium profile, which rules out most of the cheap replacements.

Chargers are the part of a golf cart battery setup people replace in a hurry, so this page is organized the way you shop in a hurry: by plug, then by battery type. The battery calculator will tell you how many hours your set needs at a given charger output if you want to compare amps.

Voltage, chemistry, plug

A charger has to match the pack voltage: 36V for six 6V batteries, 48V for six 8V, four 12V, eight 6V or a 48V lithium pack. A 36V charger on a 48V pack never finishes; a 48V charger on a 36V pack boils it. Only the Lester Summit II switches between them; everything else on this list is one voltage.

It has to match the chemistry. Flooded lead-acid wants a charger that finishes with a long float and an occasional equalize. AGM wants a lower finishing voltage and no equalize. Lithium wants a fixed cutoff, 58.4V for a 48V pack and 43.8V for a 36V pack, and then nothing; no float, no trickle. A charger with the wrong profile does not fail loudly. It shortens the pack’s life quietly over a year.

And it has to match the plug. The receptacle on the cart is the part that varies most by make and year, and it is the first thing to identify.

Plug types by cart

Club Car round three-pin: every Club Car from 1995 on, DS, Precedent, Onward and Tempo. Club Car DS before 1995, 36V, used a crowfoot plug.

EZGO PowerWise D-plug: 36V EZGOs from 1994, which is the Marathon’s last year, the Medalist and the TXT through 2009. The D shape keys the plug so it only goes in one way. EZGO Marathons before 1994 used a crowfoot.

EZGO notched three-pin: the 48V EZGOs, TXT48 from 2010 and the RXV. It is the connector Delta-Q uses on its QuiQ chargers, so you will see it called a Delta-Q plug. The RXV receptacle adds a charger interlock wire that disables the controller while the charger is connected, so an RXV wants a charger listed for the RXV.

Yamaha: G19 and G22 use a round two-pin. Drive and Drive2 use a three-pin that is not interchangeable with Club Car’s or EZGO’s. G14 and G16, the 36V Yamahas, use the two-pin as well.

SB50 Anderson: the grey rectangular connector most lithium kits ship with, along with a receptacle to replace the stock port. If a previous owner converted the cart, this is probably what you have.

If the cart’s year is in doubt, the fitment pages for Club Car, EZGO and Yamaha show where the serial plate is. Adapter cables between most plug types exist for $30 to $60, which is how the NOCO and other bare-terminal chargers connect.

How many amps

Stock chargers run 15 to 21 amps, and that is the right range. A 48V 15A charger refills a flooded set from half in about eight hours, which is overnight. Twenty amps saves two hours. Past about 25 amps you are heating flooded batteries more than charging them, and most lithium packs cap their charge current at 20 to 50 amps in the BMS anyway, so a bigger charger buys nothing.

What matters more than amps is that the charger finishes correctly. A flooded set that never reaches full sulfates; the charging guide explains how to tell whether yours is finishing and how often to equalize.

Onboard computers and charger interlocks

Two carts complicate a charger swap. Club Car DS and Precedent models with the onboard computer (OBC) use it to control charging; a replacement charger either has to work with the OBC or the OBC has to be bypassed, which some owners do when the OBC fails. Ask the seller which the charger expects. Precedents from about 2014, and the Onward and Tempo, dropped the OBC for the ERIC charging system, which adds an interlock wire at the receptacle; buy a charger listed as ERIC-compatible for those.

The EZGO RXV has a charger interlock: EZGO’s manual says the controller is disabled, so the cart cannot be driven or towed, while the charger is connected. The interlock runs through its own wire at the charge port, and when an older port fails it can tell the controller a charger is still connected, which leaves the cart dead after you unplug. That is a receptacle fault, not the park brake, which is the separate automatic motor brake released with the Tow switch. Buy a charger that lists the RXV so the plug and interlock pins match. The RXV upgrades page has more on that system.

Where to keep it and how to use it

Mount the charger on the garage wall near the outlet with air around it, not on the cart floor where it collects dirt and gets kicked. Plug the cart in every time it comes home, even after a short run; flooded batteries live longest when they are never left half charged, and lithium does not mind. Let the charger finish on its own. Pulling the plug when the fan slows down is how a flooded set ends up chronically short.

If a flooded set is more than four years old and the charger has started running longer than it used to, the batteries are the likely problem, not the charger; the test guide will tell you in an hour. And if the charger is dying at the same time as the pack, the lithium overview is worth a read before you buy either, because every kit there includes the charger.
