1.3 Battery Management System
Page 4 of 9
Our lithium iron phosphate (LiFePO4) battery pack includes an onboard digital battery
management system(BMS). The BMS monitors voltage, current and temperature on both
an individual cell and battery pack level. If any of these measurements deviate outside
of their safe operating ranges, the BMS will actively work to correct the deviation. If the
deviation cannot be corrected automatically, the BMS will initiate a self-protect shutdown
by opening the internal contactor, disconnecting the battery from the charger and loads.
Overcurrent protection – If the charge or discharge current of the battery
exceeds maximum permissible levels, the BMS will disconnect itself automatically. To
recover from a high current shutdown, remove the load from the battery, and then rest
the battery by turning the battery OFF and back ON.
Overcharge protection – If the battery`s voltage exceeds permissible levels the BMS
will disconnect itself automatically. To recover from a high voltage shutdown, remove
the charge source from the battery. The battery will automatically reconnect once
the charge source has been removed and the battery’s voltage drops down to
permissible levels.
Over discharge protection – If the battery`s voltage drops below permissible levels the
BMS will disconnect itself automatically. To recover from a low voltage shutdown, remove
the load from the battery. At this point the battery should be charged immediately.
If the battery does not start on its' own, you may need to put a charger on the battery. If
the battery is so discharged that the Low Voltage Shutdown cannot be cleared, the battery
must be returned for non-warranty service.
Short circuit protection – If the battery suffers from a short circuit, the BMS will
automatically disconnect. The battery will resume normal operation after the short
circuit is removed.
Temperature protection – If the battery`s temperature exceeds permissible levels
the BMS will disconnect itself automatically. The battery will automatically
reconnect once the temperature has returned to permissible levels.
Safety shutdown features on your inverter(s) and charger(s) should be
the rst line of protection against overcurrent or over voltage situations. Set your
system’s max current, high battery cutoff (HBCO) and low battery cutoff (LBCO)
according to the Charge / Discharge Parameters section of this manual. The
Battery Management System`s Shutdown is designed as a last resort self-protect
shutdown, and should not be relied upon for managing charge voltage or
currents. Doing so will signicantly shorten the battery’s life expectancy and
could negatively impact your inverter(s) or charger(s).

5.BATTERY USE AND MAINTENANCE
5.1 Battery Storage
Storage temperature 0°C~40°C (Optimum storage temperature 15°C~25°C, low
humidity). Battery performance is affected by temperature. Especially the change in
battery capacity. This is a normal phenomenon. Avoid condensation caused by
temperature changes during storage. Failure to do so can lead to corrosion, rust and
internal battery failure.
5.2 Battery Check Before Use
● After receiving the battery, rst check the packaging carefully. Make sure there has
been no damage to the battery during shipment.
● Please check the battery exterior for any damage or leakage. If there is any damage
or leaking, please contact your installer or distributor immediately.
● Please check the polarity of the positive and negative output terminals. Make sure the
battery voltage is within a normal range. If the battery terminals are dirty or rusty, clean
the terminals with a dry cloth before use. Poor performance may occur due to poor
wiring connections to the charger or the loads.
5.3 Battery Installation
● Please install the battery to ensure minimal dust, metal or other foreign materials. No
smoking or re during installation. Avoid a short-circuit of the battery to prevent
equipment damage or personal injury.
● The battery should be installed in a well-ventilated space with no direct sunlight.
Do not install where it could be submerged in water. The use and storage of the
battery should be kept away from any ammable and explosive materials.

● When fastening battery terminals, please don’t use excessive force, or the terminals
could be damaged.
● After installation, please check whether the terminal fasteners are still tight. Clean
the surface of battery with dry cloth. Please don’t use oil or other volatile organic
solvents to clean or it may damage the case.
● Please make sure that the positive (+) & negative (-) polarity is correctly connected.
Failure to wire correctly may cause a re or damage the battery and electrical
appliances.
● After installation, test the battery and equipment. Observe whether the equipment
and battery are working correctly.
5.4 Battery Operating Requirements
● The charge and discharge current of the battery shall not exceed the specied
maximum charge and discharge current. Current input or output beyond recommended
levels may affect the lifespan of the battery, damage the internal circuitry, or even
cause a dangerous situation.
● When the battery is in a low state of charge, it should be charged quickly. This helps
prolong battery life. If the battery is not charged quickly from an extremely low state of
charge, battery life will be affected.
● LIFEPO4 batteries prefer a shallow discharge and charge cycle. For longest life, a
discharge of 20%, leaving 80% of the nominal capacity is recommended.
5.5 Battery Operation
● It is possible to over-discharge the battery if the battery is not used for long time. In order
to prevent over-discharging, the battery shall be charged every 2 months to maintain a
certain voltage range of 49.95V~51V . For best life, a SOC/ capacity calibration shall be
performed. This calibration method charges the battery fully, then discharges slightly to
prevent an a possible over-discharged state. Letting a battery sit for months without this
procedure can lead to battery problems. Contact your installer or distributor for more
information about this procedure.
● Don’t use organic solvents to clean the battery case.
● A battery is a consumable product with limited cycle life. Please replace it before the
diminished capacity can’t meet the needs of the end user.
● In order to prevent failure of the overcharge protection board, do not charge for overly
long periods of time. After the battery is fully charged, remove it from the charger. Only
use acceptable battery chargers and operate the chargers according to proper voltages
for recommended amounts of time. Failure to do so can damage the battery and
possibly cause a potentially dangerous situation.
● A shallow charge and discharge of the battery ensures that the battery can be used
optimally.Overcharge and over discharge may cause the battery to overheat, re or
failure, shorten life, or other possible dangerous situations.
● Battery switches, displays and USB ports are not considered warranty items. The battery
can function ne without these items.
● Waste lithium batteries should be recycled and disposed in accordance with local laws.
