The in-line balancers do not "send a signal" to the charger, they simply just cut the circuit that allows the main leads of the pack to feed through into the charge ports of the charger, making the charger think the battery has been disconnected. If this happens with my charger, my charger will began sounding an alarm indicating an error has occurred.

However, if you have a Hyperion Charger, you can connect the Hyperion Balancers to them with a data link and then they function just as the chargers which have built in balancers, they will adjust current rate if one cell is already full while the others are not to allow the other cells to come back to balance.
