3. 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.

6. Storage and transportation
The battery must be packed and protected well during transport.
The lithium battery must be transported according to the rules for
transport, these should always be followed (transportation code
UN3480/UN38.3).
Never lift the battery by the terminals, only by the handles.
The battery should be stored in temperatures from -10℃ to +30℃.
During transport, the battery should be about 50-60% charged.
The battery should be charged every three months to keep it active
so that it always works maximum.
7. 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.
7. Install the LiFePO4 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.
