I received the LOSI DBXL, and trying to charge a 6V NiMH from a 308i DUO with the Balance Boards provided, however the ports are uneven pos and neg. I also realized the clips off the 6v NiMH can be turned either way on the Balance Board. Do i need another Balance board another accessory to charge this 6V NiMH, an if not which port do i put the 6V NiMH into on my charger? HELP
