not quite sure.it is the ORI30117 Team Orion Advantage DC Computerized Charging System (NiCD, NiMH and Li-Poly) .I really know nothing about these pro chargers as im quite old school..plug and go.I figured it was the same as a wall charger for $9.99 but a whole lot quicker.I dont know what peak sensitivity or MaV or discharge rate or anything means for that matter.Im just trying to get it to read the hump pack and throw a charge to it but it wont because im sure my sttings are all screwed up.
