Longer Storage Life Lithium Polymer Battery Pack 72V Lifepo4 Three Wheel Motorcycles ,Golf carts 

Features:

1.lifepo4 battery with Long cycle life and good safety 

2. with unique technology to keep Good consistency of the battery pack

3. can tolerate the Wide range of operation temperature

4. Stable discharge voltage performance, good rate performance

5. Environmentally-friendly product, non-toxic, production under standards of ROHS

6. With a advanced BMS, monitoring the state of batteries and protecting it.

BMS function:

A BMS may protect its battery by preventing it from operating outside its safe operating area, such as:

1. Over-current
2. Over-voltage (during charging)
3. Under-voltage (during discharging), especially important for Li-ion cells
4. Over-temperature
5. Under-temperature
6. Ground fault or leakage current detection (system monitoring that the high voltage battery is electrically disconnected from any conductive object touchable to use like vehicle body)

The BMS may prevent operation outside the battery's safe operating area by:

1. Including an internal switch (such as a relay or solid state device) which is opened if the battery is operated outside its safe operating area
2. Requesting the devices to which the battery is connected to reduce or even terminate using the battery.
3. Actively controlling the environment, such as through heaters, fans, air conditioning or liquid cooling.
