what everyone needs to understand is that the Mavic batteries have the charge controller built into the battery pack. So all it looks for is a fixed 13.05V and 4.5A source. It doesn't know or care where it is coming from as long as it is within spec, it will proceed with charging the battery. The battery charge controller (on the battery) then determines the appropriate voltage and amperage in which to use based on the battery's charge level. The cell balancing is also monitored and controlled onboard the battery. Once it is fully charged, the charge controller inside the battery shuts off and regardless of what the charger is outputting, will not try to charge the battery. So the fear of using a non-OEM charger is not necessary. If you have concerns, simply check the actual output voltage and amperage before you use the charger. If you hook up a charger with too high or too low a voltage, the battery will alarm and stop the charge cycle to prevent damage to the battery.
So by integrating the charge controller inside the battery pack it has made it very easy for manufacturers to build aftermarket chargers since they only have to develop a power supply than can output 13.05V at 4.5A and not worry about all of the complexities of charging a Lithium Ion battery.
