Charging problems

Swamppro

We just picked up our first golf cart. 98 ezgo converted to 48v. Previous owner left the 36 volt plug on cart and put matching plug on quiq charger. All batteries replaced less than a year ago. 6 8v deep cycle. The charger will only go into low voltage and sometimes go into protection mode. The highest I saw bank get was 45 v and cart will move 15 feet and drain bank down fast. Could I plug in neighbors 36v charger to charge batteries to test? Thanks in advance

What is the model number of the Quiq charger?

They come in both 36V and 48V versions and 45V is about what a 36V charger tops out at.

-----------
At 45V, your batteries are less than 10% SoC (State of Charge) and trying to move the cart with them is most likely irreversibly damaging the plates.

Thanks for the reply. It is a 912-4800. I put my meter directly to plug in charger and getting nothing

The Quiq charger tries to "trickle" charger the pack up to a minimum voltage before it goes into its normal charge cycle, so I'm pretty sure you ought to measure some voltage at the output plug when the power cord is plugged into AC Power.

What error codes are you getting? (See attached Manual)

No error codes except for one time. The 1 on the scale just steadily blinks

Suggest you contact Delta-Q. Maybe they can tell you what is going on with the charger.

Or, replace it with a DPI Accusense charger: http://www.cartsunlimited.net/chargers-36-48v.html

Start with a battery voltage check....you could still have a bad battery.

All the batteries are less than a year old, full of water and show about 7.5 volts.

Odd. Now the charger is working charging at 53v right now. Ain't touching anything! Bringing charger to dealer Tuesday to get checked out

Got it charged a good bit and took kids for a ride. 16 mph flat land. Will charge it fully and see where I am at. It has a posi rear end in it that is going to play hell on the yard.
