I have been severely humbled by a battery buying mistake and now intend to build using Sinopoly cells. My PMAC motor draws 350a at full throttle and while I don't intend to use full throttle except in conditions of (high winds/fast current) I don't want to ever exceed Max Discharge Current. This puts me in the 400a 1C minimum. I would prefer 500a @ 1C.
I have found 500ah Sinopoly cells on Alibaba at a good price but would like to better understand how to ensure they are new grade A Sinopoly grade A and new. Has anyone purchased Sinopoly's in that size or could recommend decent vendors?
