The E2650 1S LiPo Battery Gang Charger includes six independent chargers with jumper selectable charge currents of 100mA and 500mA. Using independent chargers is safer for the batteries than paralleling them and using a single charger because there are no high discharge currents between the higher charged batteries into the lower charged batteries. The advanced charge algorithm features a trickle charge preconditioning followed by constant current charge, and then a 4.20V constant voltage charge. The charger is protected against reverse polarity at the power input, and the batteries are protected against reverse discharge due to a faulty or shorted power input. During the constant current charge stage, the charger chip is thermally protected and will reduce the charging current due to overheating or if in high ambient temperatures.
