Yes, I know... I'm using Turnigy Flightmax 5000mAh 5S 30C LiPo's, 4 of them. Wired in 10S2P. So they should be capable of 300A continous , but they can't even handle 130A peak. All the cells are good. I seriously don't know what's wrong with the LiPo's...

But does anybody know the answer too my question?
