first of all im running an HPI Sprint 2 Sport, i know its not the greatest but it was good back then for being a beginner. since then i have added a mamba max 5700 to it and would like to get a better battery for it. im looking at an 8 cell 9.6v, half 8 pack setup with elite 5000 sc batteries and a female deans connector. problem is i am having trouble finding a good charger and discharger at a price that isnt going to break me. any one with any ideas?
