Motor amps?

[hemiblas]

My emaxx 3905 geared for 38mph is about 35A continuous and 78A peak. I know the more efficient motors peak higher. If you are looking for a little extra the SPC 8000mah pack is rated for 100A continiuos and around the same price. I have run the truerc packs and SPC packs on this setup and they hold their voltage and never get hot. In general though its good advice to get higher C rating, but it depends on the manufacture. Not all of them are as trustworthy as others. I have had 20C 5000mah packs that dont even come close to the truerc and spc packs rated at 10 and 12C.
