  • Actually many chargers will charge through the main “discharge plug as well” and only balance through the 4 pin connector.
    The main connector has all the cells wired in series and can carry the full discharge rate, the smaller multi-pin plug has pairs wired to each cell, so that you can monitor each cell voltage independently while charging. This is also used by the charger to draw down a cell that is slightly higher in voltage while charging so that it will end up balanced across the pack.
    You can read more on various RC forums if you wish

No public wish lists :(
