But they dont just send power to the Battery. If they did they would not need to connect to the balancing port as well. The charger itself is what will keep the cells balanced and conditions the cells. You dont need to have the balancing port connected to charge, without it would just supply power and charge it. But it would not balance it and monitor the battery during that as well.
There is alot more going on inside of the charger then just supplying power. It does all of the same work as the chargers we use with RC Car Lipos, though it is just a very small and slow charger. Except the DJI charger does not have the menu that you have to go through to set all of the parameters needed to charge your battery. If you had to setup a charger to charge a DJI lipo you would have alot of confused people on this forum trying to figure out how to charge a battery safely for the first time. DJI was smart and recognised that would have been a issue and made an all inclusive charger with all of the settings put in place so people could not mess up or become very confused.
The charger just supplies power as o said.
It does not connect to a balancing port on the battery as there isn't one.
