Thanks WIGMAN. New to Lipo and had originally heard that 1C was the limit. But have seen some saying 4C or 5C. That sounded awful high. I've got a TP610C so 10 Amps is the limit and it sounds like that should be just about right. I have no illusions about running with the big boys. Just want a decent ride without having to buy new packs every 2 weeks.
