I've had my summit for a while now and am thinking about going lipo. I would use the stock ESC and just buy a lipo cutoff. I already have a Nexus 20C 5000mah lipo that came with my slash, but I cant find another one like it. So I was wondering if I could have the same C rating, same mAh, but have a different brand of lipo? Like SPC or something like that. Thanks.
