There are a ton of matchers out there,using 35 amp matching there is even one still using 20 amp matching I think.I'll let the track decide what works and what doesn't.Right now I can see no diffrence on the track between a 30 amp battery and a 35 amp battery,matter of fact I have seen 35 amp batteries get out run by 30 amp batteries on several occasions,
very recently by me.I don't really cycle my batteries anymore,I just keep track of the # of cycles I put on them,as I've found that fresh cells are a key facor with batteries,so I try to rotate my cells,and keep the freshest cells for racing and the older packs for practice packs.
