"XH" Multi-Adapter Balance Board (2S-6S) (ProTek, Align, E-Flite)

This board is also designed to allow you to balance multiple batteries at once, as you can charge and balance one 6S battery, two 5S batteries, two 4S batteries, three 3S batteries or three 2S batteries at once on a 10 cell charger. When you connect multiple batteries, the batteries also need to be connected together with a serial charge lead. You should also make sure all the batteries are discharged or used in the same groups that you charge them in (ie: two 5S batteries used in series for a 10S battery pack etc).
NOTE: This balance board will support up to 10S packs, but the balance board connector wire will only accommodate a 6S battery.
