Replacement Rechargeable Battery and Charger Store - Item #: 481036620 - Battery Chargers

Tenergy 48V 5A LiFePO4 Battery Charger - 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 Protection Short Circuit Protection Output Reverse Protection. Charging time: Charging Time= (1.41 * Ah rate of the pack) / 5A charge current. Built-in IC to cut-off power automatically when battery is fully charged. LED indicators LED 1 = Red = Power On LED 2 = Red = Charging LED 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 first the ''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. Indicator 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.

Warning: Only for use with LiFePO4 16 cell battery pack (If used with battery pack of less cells it will cause damage to battery and possible personal injury may occur). Unplug charger after use. To prevent electrical shock, DO NOT remove casing. Be careful of high-voltage inside charger. If failure happens, please contact us. Users and non-professional technicians are prohibited to open the charger! Keep charger out of children's reach. The charger and battery belongs in indoor environment with good ventilation and good cooling system, Do not expose to humid, high temperature, flammable, explosive gas environments. Do not bring charger along during transportation to prevent shock damage! Read the instructions carefully before using. Damage caused by improper use is not covered by warranty.
