It just chargers threw the balance lead, many do this. Most of all the STOCK RTF chargers that come with your plane charge threw the balance tab. As long as the current is not too high you're ok.

3A output is a bit high I think for balance tab wires but I guess not according to the charger manufacturer.

Hi Simon,

the manual and the technical information is pretty clear. This is a 30W charger with 3A max. charge current and 0.1A max. balancing current:

Charge mode

Connect a suitable genuine GRAUPNER Lithium-Polymer battery pack to the output of the Li- charger 4 plus. The pack must consist of no more than four cells. Connect the balancer connector Graupner/EH to the balancer output.


First you connect the normal battery connector to the charger, then you connect the balancer connector.

Jürgen
