Hey guys im building a 8T-E and looking for lipo's to run and I cant figure out the differance in a battery that is 20~30C and one that just says 25C like the 4s batteries on Hobbycity. I dont understand what 20~30C is compared to 25C. Why do they use this: ~. Should I be using 4 cell's? Im running a Neu Castle motor and MMM ESC, do you think this will be the best setup for strictly large track racing? A little help would be much appreciated.
