GREEN LANTERN 12.8V200Ah 12V Lithium LiFePO4 Battery
Product introduction
The Green Lantern 12V series has been designed for various types of applications such as loadshedding/backup power solutions, and even outdoor applications such as camping/4×4’ing. There is an advanced BMS built into the battery which is responsible for collecting and analyzing the voltage, temperature and current of every cell. It serves various functions such as over-voltage protection, under-voltage protection, high temperature protection, low temperature protection, short circuit protection and cell balance.

Installation Guide
Preparatio n
Before installation, please read all safety information provided in this document. If you have any questions about operation and safe use of the battery, please contact a technical support engineer.
Before Operation
-
Qualified electrical qualification is recommended.
Remove all metal items, such as jewelry, watches, pens etc. -
To ensure the safety of construction personnel and equipment, disconnect the battery pack from the operating equipment during wiring.
-
Pay attention to the terminal voltage polarity of the battery module.
-
Make sure installation tools insulating and use tools correctly.
-
Follow the connection port description and system connection diagram.
-
It is absolutely forbidden to plug and unplug when the battery is working. Operation should only be done after the power supply is disconnected.
-
Before the formal operation, ensure that the power terminals are properly connected and tighten the terminals securely. When it is necessary to measure voltage, make sure to use instruments and tools correctly to avoid short circuiting.
It is strictly prohibited to disassemble the battery without permission of the professional technician from the manufacturer.

Attention
-
Charging current should be less than the maximum current. Exceeding the recommended current may damage the battery. ；
-
The discharge current should be less than the maximum discharge current specified in the product specifications.
Any discharge current larger than the recommended current may damage the battery. -
Non-professional personnel is prohibited from disassembling the battery.
-
Reverse charging the battery is strictly prohibited.
-
Battery pack should not be used or placed at high temperature. It will cause overheating, function failure or shorten life span.
-
Battery pack should be placed in a dry and cool environment when it is not in use. Immersing into water is prohibited.
-
It is strictly prohibited to install and disassemble the battery pack when it is live.
-
For optimum performance, you must charge at 14.6V. If you do not, you will not be able to reach the full usable capacity of the battery.
-
To ensure the best performance of the battery when stored for long periods of time without use, the battery should be charged and discharged every three months.
-
After the battery discharge protection kicks in, it can be reset in the following ways:
- Let the battery stand for 15-20 min The battery will be automatically unprotected after standing for 15-20 min.
- Use the charger with OV charging function (It can charge the battery starting from 0V) to charge the battery. Once fully charged, the battery can be used normally.
- Use another 12V lithium battery with same capacity to connect in parallel. Leave them connected for over 12hrs. After that, fully charge the battery and it can be used normally.
- If solar charging is used, please set the regulator to the charging mode of B04 lithium battery.
When charged with controller and the controller output is used to connected load:
It is recommended that the controller is set to the below parameters. This is to avoid the battery failing to recover when the BMS cuts the battery off due to protection after a continuous current discharge.
Overcharge Protection Voltage : 14.6V
Overcharge Recovery Voltage : 14.2V
Over-discharge Protection Voltage: 10V
Over-discharge Recovery Voltage: 11.2V
The above settings can ensure that the controller triggers the protection first instead of the battery BMS which can prolong the service life of the battery.
