I've got a pair of joye twist 10000mah batteries and also a set of SLB-kGo 1100. I don't use just one device through the day but I use 3 different ones. Ok question is, I've been letting my eGo and kGo use them for about 2 days and then put em on the charger and swap em out. I use each one for different setups, cause I'm still expermenting with different stuff. Should I let the battery shut off on it's own or just keep charging every couple of days.
