help with ez-go 48 volt

berssfarm · 02-01-2017, 10:41 PM

New to the golf cart scene, bought a 48 volt ezgo not running batteries we're weak charged all batteries to minimum of 5 volts. Plugged charger in and flashes showing battery voltage fault any help would be appreciated.

Well your batteries need to be much higher than 5 volts a piece. If you don't first get the battery situation taken care of then we can't really move forward from there. It sounds like that's your issue though. Your voltage is probably too low to turn on the charger too

If you or any friends have a 6 volt or 12 volt charger, you need to charge up one at a time or two at a time, until you have enough for your charger to kick on.

I'm assuming you don't have 8 volt batteries.

They are 8 volt and I charged each battery up to 5 volts thinking that is enough for charger to start, when I plug cart charger in I get 2 red flashes and the code says battery voltage fault.

Missed the reply about need to be higher than 5 volts. Thanks, I will charge them more. what is the the volts needed for the charger to start charging.

You probably need the battery pack around at least 40 volts or more. Do the best you can to get the pack as close to 48v as possible

I'm not familiar with your charger, but if you connect each battery to a 12 volt charger, and get them to 8 volts, I'll bet that would be enough for your charger. Monitor hourly, to make sure you don't over charge them.

It is also very likely the QE charger is dead and that is why the batteries were left to discharge so much.
Add the 12v charger to any pair of 8v and plug the OEM charger in at the same time. The added 12v charger should kick the pack up high enough to signal the charger to come on.

When I have this issue I put the charger in the start/crank mode, it's usually the highest amperage out put on the charger. Let it charge a few cycles then you should be good to swap back to a regular charge voltage.
