I've been using nothing but NiMh's but i really would like to try Lipo's in the new boat i built and a future project boat i'm thinkin about, a 30" Aeromarine .20 Sprint Cat. Everyone say's Lipo's are so simple, even more so than NiMh's, but everything i read makes them sound like a pain. Anyways, i read somewhere, on here i believe, that the MRC Super Brain 977 is not a good charger for Lipo's, why?? The manual say's it is capable of charging Lipo's, what kinda of problems have any of you had with the 977?? I use it for my NiMh's and it works great. I have no idea where to start on what Lipo packs to run but i can get to that later, right now i want to know if my Super Brain 977 will be ok for Lipo's before i go any farther, i'll stick with NiMh's if i have to shell out a couple hundred bucks for another charger. Thanks, convince me to go Lipo!
