98 EZGO won't hold charge

Colemajl · 02-22-2017, 08:16 PM

It's a 98 EXGO txt series cart. Batteries are 6 months old and all tested good. Basically the cart starts off good for first 20 minutes then the cart begins to lose power quickly. Charger also tested good. I also checked all connections. Any ideas?

Hmm the batteries are 6 months old and were tested so I guess it's not your batteries. Do any wires going to motor or controller feel hot? I can't be sure but your controller may have an issue. Once it dies down after 20 minutes take a reading of the pack voltage and see what it is. Do you test your batteries with a meter or a load tester?

I tested with meter. Pack tested at 37.6. I will drive around tomorrow and feel wires going to motor and get back.

Make sure you charge it tonight and once it dies down considerably measure the voltage

Did you get 37.6 fully charged and rested? It looks a bit low, 38.2 is the standard for a 36v pack.

Test each battery for voltage to see if you do not have a dud in the pack.

Here is JonnieB SOC chart for reference. 37.6 is about 80% charged.
