Title: need help in RC Car battery Post by: jayanandan on March 17, 2017, 10:38:52 AM Hi, I bought recently the Sandstorm Off-Road Truggy RC car for the cost of Rs 6995/-. The battery(7.4v 800mah Li-Ion) was charged for around 8hours. It was running without any issues for 5 minutes. Then the throttle was not responding and indicating that the battery is too low. Then I charged for 2 hours of time. It was not running even for 2 sec. Then i charged for 6 hours, again no response. I changed the battery from the shop where i bought the car. I charged the new battery for 8 hours as he suggested. no luck. The same issue has started again. Anyone please suggest, whether i need to check/change the battery or charger (charger output is 7.4v ~ 800amp). Please someone help on this issue...

I don't think the problem is with motor or receiver. That's why i mentioned that it all started again. It seems that every time i change the battery it works fine. I'm suspecting that either the battery or the charger is having the issue.
