Allows the connection of XH balance connectors (almost all packs made use this plug) to all Hitec chargers with Lipo/LiFe?LIon charging capability. This board works with almost any charger that has a 7 pin balance input connector with .100" on center pin spacing. If you think your charger is weird or unusual and not this normal spacing, measure from the center to the center of 6 pins, if the measurement is .500" (1/2") and you have 7 pins in total, this balance board and it's harness should work.
