.red {color#F00;font-weightbold;}Features:Intelligent charger designed for 16 cell LiFePO4 battery packs. CPU control and pulse width modulation (PWM) technology, charging current and output voltage is controlled accurately to ensure fully-charged and avoid over-charging. Built-in cooling fan to ensure charger long service life. Safety protection Over Voltage ProtectionShort Circuit ProtectionOutput Reverse ProtectionCharging time Charging Time= (1.41 * Ah rate of the pack) / 5A charge currentBuilt-in IC to cut-off power automatically when battery is fully charged. LED indicators LED 1 = Red = Power OnLED 2 = Red = ChargingLED 3 = Green = Fully Charged User Instructions Check the output plug of this charger and make sure it is not loose.Before charging, please connect the charger’s alligator clips to battery firstthe "red" clip connects to the POSITIVE pole and the "black" connects to the NEGATIVE pole. After, connect the input power plug to the indoor power supply.The charger applies the intelligent charging method of constant current and constant voltage. The charger will automatically shut off when battery is fully charged. Unplug the input power supply then disconnect the output clips.When charger is not in use or finished charging, be sure to unplug input power supply.Indictor LED instruction "Charging" indicator shows "red" under normal charging state. It turns into "Green" when the battery is fully charged, the battery can be put into use at this time.The charging voltage of this charger is 58.4V, and shut-off current is .5A. It can only be operated when connect with not fully charged battery.
