Battery Specifications
Use high stranded copper and heavy gauge cables to handle possible loads from the battery. Make sure to
maintain identical cable lengths.
• Verify correct polarity
Reverse polarity can and will destroy the battery. Use a multimeter to determine proper polarity.
• Tighten the cable connections
Over-tightening cable connections can cause terminal breakage and loose cable connections can cause
terminal meltdown or fire.
• Place the battery in a well-ventilated area
• 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.
• Standard charging consists of charging at 0.2C constant current until the battery reaches 14.6V. The
battery is then charged at a constant voltage of 14.6V while tapering the charging current. Charging is
considered complete when the charging current has tapered to 0.02C. Safe charging requires
temperatures between 0℃ and 45℃ (32℉ and 113℉) and takes approximately 7 hours.
• For standard discharging, the battery is discharged at 0.2C constant current until the battery reaches 10V.
Safe discharging requires temperatures between -20℃ and 60℃ (-4℉ and 140℉).
• 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℉).
• 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.
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.
