I just bought the Team Orion Advantage charger and Team Orion 1600NiMh hump packs.Maybe i sound a little ignorant here but can someone please help lead me through the process of charging this thing?I dont know about volts and amps per hour.Every time i think i might have it set up it tells me "check battery".Any help would be greatly appreciated.Also,how long do those packs take to charge/discharge?
