● 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 specied
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.
