Battery Operation
Battery Storage
Battery Management System (BMS)
Depending on shipping times and the time since manufacture, the battery may be received at a partial state of charge. Please
fully charge the battery prior to the first use.
Use high stranded copper and heavy gauge cables to handle possible loads from the battery. Make sure to maintain identical cable
lengths.
Verify correctpolarity
Battery Installation
Safe and reliable installation requires trained and certified technicians. This section can only serve as a guideline as all scenarios
cannot be covered.
Wear protective clothing and eyeglasses
Size the battery cables appropriately

Reverse polarity can and will destroy the battery. Use a multimeter to determine proper polarity.
Tighten the cable connections
Please charge the battery to 30%~50% and store the battery in an open, well-ventilated, dry, clean area with temperatures of
around 23 (73.4 ).
The BMS will protect and shut the battery down when it is over-discharged or short circuited. In these rare cases, the battery will
show 0V voltage. Please activate the battery using an external charging source that has lithium battery activation function. Please
contact our Tech Support team at [phone] for more information about the BMS.
Long periods of storage can deteriorate the battery performance. It is recommended to charge the battery at least once every
three months to prevent over-discharge.
For standard discharging, the battery is discharged at 0.2C constant current until the battery reaches 20V. Safe discharging
requires temperatures between-20 and 60 (-4 and 131 ).
Standard charging consists of charging at 0.2C constant current until the battery reaches 29.0V. The battery is then charged at
a constant voltage of 29.0V while tapering the charging current. Charging is considered complete when the charging current has
tapered to 0.05C. Safe charging requires temperatures between 0 and 55 （32 and 131 ) and takes approximately 5.5
hours.
Place the battery in a well-ventilated area
Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
