→ You really need to tell us more about your car.

What batteries are you running?
How old are they?
What Charger?
How long has it been unplugged from charge cycle?
What did you try to drain the pack with?
Any other mods done to the car?
History?(how long have you had it? When was it last running good?)

Get youself a meter and take a V reading at the controller, then take a reading directly from your battery pack and report back here with your findings.
