This simple charger will do the job: Can charge a 2-4s battery just by plugging the balance connector in, without any need for further adjustment. We also created an option for those that would like to charge via USB from their computers. Please note you must use 2 USB ports to achieve 10 volts. This unit does not have any AC to DC adapter.
One of the nice features with this charger is it will charge very low cell batteries unlike other chargers. In testing we were able to pull dead battery back to life since its not limited to low voltage cells for charger. Also it charges each cells equally which impressed us highly.
