[tha5150]

moved, took a vacation, got married, went on our honeymoon, blablabla.. basically my Hyper 8 and Lipo's have been sitting in the garage, untouched for several months. i know this is not good for the lipo's. what should i do to get things back to normal? what sort of charge and use should i do? kinda a re break-in period. its a 4s 5000mah. i have 2 of them.
