Im currently running a 5800 2cell 30 lipo in my caldera 10e with no issues and its pretty beastly. Can these cars take a 11.1 v lipo and if not why? Also, what does a 11.1 v give you over a 7.4 volt? More power? Also, Im about to buy either a avalanche xte or a hurricane xte and need to know the best lipos to use in them. Iknow they come with 3600 lipos but I am def going to want more runtime. Should Ijust use the same 5800 lipos Iuse for my caldera? The one Iuse in my caldera is a hexfly and I got it for 67 bucks. Doesnt seem to bad of a price. Any other brand recommendations
