I got my balance plate today . This plate lets me balance multiple packs as a single pack . This plate does the same thing brian's y harness does . This one does both xh & eh plugs . all i did was trim the socket a little so the eh plug would go in eaiser . I will be balancing two 2s packs as a single 4s pack . Also the stock protek plug goes right into my hyperion 610i charger.
