I have a question about power supplies. I will be charging 2 sets of 5s batteries at the river. 10s2p (4) 5s 5000 mah revos. buying a 1600 continuous watt generator. 2000 watts peak. i have (2) hp 47 amp 575 watt 12 volt power supplies. (2) revolectrix powerlab 6's. would it be better to hook up the power supplies for 24 volts and power the chargers off that, or run each charger off it's own 12 volt power supply. thanks
