The voltage reading and battery capacity meter is inaccurate. It only charges my Lipo-4 battery up to 14.2 volts. Full charge voltage for this battery is 14.6 volts. It gets very hot while charging.Update 2/21/2021 This battery charger now fails to recognize that it's connected to a battery and no longer attempts to charge. Save yourself the trouble and don't buy this faulty, unreliable, short lived battery charger.
