Summary
Microcomputer (MCU) controlled 3 stages intelligent battery charging technology, which can accurately track the charging process, and fully charge your battery in an optimal condition, in order to prolong the service life of your battery.

Application Scopes
Used for charging Lithium phosphate LiFePo4 batteries, used in electric bicycle, electric tricycle, electric forklift, electric vehicles, electric motorcycles, electric sweepers, electric boats, electric sightseeing cars, electric golf cart, electric tractor,electric lift trucks, electric medical equipment, electric transportation trucks.

Maintenance and Precautions

• Before use, carefully check whether the specifications and
  performance of the charger match the input voltage of your battery.
  Your battery Voltage must match your battery charger.

• The battery and the charger must be correctly connected with
  correct polarity, positive (Red) and negative (Black). Do not
  connect wrongly.

• Charging cables must be firmly connected to the battery
  terminal. Loose connections can damage the battery and the chargers
  due to generation of excessive heat.

• Do not short circuit charger cables.

• While charging, if your charger or battery is damaged,
  disconnect the input mains power cable and the output connection
  cable of the charger immediately.

• If external mains power cables are used other than the supplied
  mains cable ensure.

Charging Mode Cycles

Precharge stage (T1): When the battery voltage is lower than normal, the battery cannot withstand large current charging. The charger will supply lower current for charging, which will activate the battery and prolong battery life. Charger will automatically switch to high current when voltage is recovered or some time is passed.

• Fast charge stage (T2): Constant current charge stage to peak voltage.
• Float charge stage (T3): Constant voltage charge.

Protection Features：

1. Over Temperature Protection: When the charger internal temperature reaches protection point, the charger will stop charging automatically and the LED flash red.
2. Output Short-circuit Protection: When the charger appears short-circuit, it will cut off the output current and the LED will flash red.
3. Reverse Polarity Protection: When the battery polarity is reversely connected, the charger will cut off and the LED will flash red.
4. Output Over-Voltage protection: When the charger output detects over-voltage, it will cut off the output current and the LED will flash red.
