This should make going to 3S in 1/10th scale a bit easy for the guys who like them in a hard plastic case: http://www.teamorion.com/Products/SL...00+3+Cell+SLPB. Price wise, you won't need to spend a ton of money. Most of you who do use lipo now have a charger that can charge 3S without an issue. You could go with a 2200-3200mAh packs and they are not that expensive. The 3S packs will not be dumping massive amounts of AMPs and they will last longer.
