I need to know the minimum C rating for a 4S lipo,in a buggy with a 2650 KV motor. Thanks in advance for any information!

I would say at LEAST 40C, in my experience. We ruined plenty of LiPos a few years ago running the 2650 and they were all sub 40C.

4S with at least a 30c rating ive been running it on my 2200kv motor for about a season and a half if its hot outside it can get warm after a run but not where its hot ! Still has decent punch .

Gearing also has the most affect out any C" rated lipo. I say that because i can go a tooth down on a pinion and with a 30c 4s lipo it can feel like i have massive torque off the line and to jumps. But than again i was using a big spur gear also.

This 2650 motor is in a buggy that i bought for my 7 year old Grandson. If I gear it low and keep the throttle endpoints turned down, could I get away with running a lower C rating?

Thanks

You could, but don't push the luck by doing this. Suddenly you want to go faster, and then you are stucked with too low C-rating batteries and try to push it and end up with ( in the worst case) a burnt out car due to too much strain on the batteries. Go at least for 40 C to be on the safe side, no point in saving money on low C's.

Agreed! You're seriously going to want to limit the throttle on this car if you give it to your grandson. If you don't he'll probably break it or hurt someone on his first or second run. I also wouldn't let him charge the batteries. Lipo's aren't that dangerous, but still some caution is needed.
