Cart stalls out under heavy acceleration

[daddyscooltv]

Ok..was able to check voltages today...

Pack was 50.4 volts after charge..

Total pack while driving stalls at 46 volts but goes as low as 37..

Tested each battery while driving.. all started at 8.4 and dropped to around 7.6-7.7 while driving..

It's getting to the point to while the cart won't go but just a few feet before it stall out..

Plugged charger in and when gauge on charger is at 15 amps voltage across the pack is 51.8... I would think the voltage would be higher than that...
