OK I know this is a thorny question at times but I'm looking for a recommendation on batterys I need 12v to power my Trxxas 770's and I want to be able to play for at least an hour, I know nothing about type or make of batterys. I have a pair of 12v gel cells but having read the forum I realize these are a stop gap at best and need a battery capable of quicker discharge. I also want something reliable and safe! so lets here from those actually running there big boats on what make and brand of battery works best. I am building a Dumas Dauntless and all up weight will be in the region of 30Ib's I'm guessing...........Paul
