Battery Management System(BMS)

The battery management system (BMS) built into each battery ensures that the battery switch off in the event of under voltage or overload and automatically again turns on as soon as the problem is resolved.

- Protection of the cell against under voltage by switching off the load in good time.

- Protection of the cell against over voltage by reducing the charging current or switching off the charging process.

- Shutting down the system in the event of excess temperature.

- Charging of the battery is stopped in case of under temperature.

High performance traction/storage battery

Lithium LiFePo4 batteries are heavy. Make sure it is adequate and safe attach and always use the appropriate transport equipment.

In an accident unsecured, batteries could become a projectile! Always take carefully with lithium batteries.

Make absolutely sure that the LiFePO4 battery is not connected with reversed polarity.

Should the battery be connected incorrectly, the BMS electronics will be irreparably damaged and must be replaced with a new BMS board. This is not a warranty case.

Important instructions

Do not open the LiFePO4 battery without consulting the dealer. Unauthorized opening of the battery voids the manufacturer's warranty.

▪ Only use the battery for the application for which it is intended.

▪ Do not short-circuit the LiFePO4 battery. The cable connections to the consumers must go through a backup to be protected.

▪ Installation and maintenance may only be carried out by qualified specialists.

▪ Do not expose to permanent direct sunlight. Protect from the effects of heat. Temperatures above +60 ° C can damage the battery.

▪ Use only compatible chargers. The battery is in a longer storage of all disconnect devices.

▪ Pay attention to proper assembly.

▪ Avoid damage of any kind, for example by falling, drilling, etc. (Risk of short circuit).

▪ Always keep the battery dry and clean.

▪ Note the plus (+) and minus (-) markings on the LiFePO4 battery and the device and pay attention to the correct polarity.

▪ The cycle capacity may vary due to the change in the working temperature and the charge and discharge rate differ from the nominal capacity.

▪ Suitable for parallel connection maximum four batteries (If need series connection, the BMS should be customized with higher cost).

Before connecting, bring to the same charge level. Batteries from different manufacturers or different types should not be interconnected.

Caution:

- Do not store at above 60℃(140℉);

- Do not dispose of the battery in fire or water;

- Do not expose to high temperature, disassemble or short circuit;

- New Battery pack must be fully charged before use.
