Thanks. I'll be adding deans connectors to them (assuming I can solder them on lol) so that should handle the power. I got them for like £16 each here in the USA so that's a real bargain if they are anywhere near 35C and 5500mah
edit: my local rc club is onroad only so I won't be racing them. I might get an onroad car if I see a bargain and then get some lipo saddle packs later on
