I use these 3S packs for everything, they are goddam epic if you'll excuse the language...good price too. I use them in pairs in my Savage Flux and in my truggy, and singles in my Jammin SCRT10, they never even get warm. 200A continuous for less than 40 bucks. I've got 8 of these packs now and never had a problematic cell. They're also a bit shorter than advertised. About 139, not 145.
