Best damn balance charger I ever had

[BrianG]

I agree with Arct1k; most balance wires/connectors are good for around 1.5-2A max. The wire size and connector type have relatively high resistance due to their size, so when you start pumping higher currents through them, you get more voltage drop across the wires/connectors. This would cause the charger to think the cells are at a lower voltage than they really are and could overcharge them as a result.

However, this type of charger is a really good idea IMO, but only if the wires where changed to something like 18GA and then a use different higher-current connector.
