Storage, Safety and Limitations
•
Charging current must be less than the maximum charging current specified in the data
sheet.
•
Charging current exceeding the recommended current may damage the battery.
•
The discharge current must be less than the maximum discharge current specified in the data
sheet.
•
Discharge current bigger than the recommended current may damage the battery.
•
Non-qualified personnel are not allowed to disassemble the battery.
•
Do NOT reverse charge the battery.
•
Battery pack should not be used or placed in high temperature. Do NOT use or store under direct
sunlight. It may cause overheat, function failure and shorter life.
•
Battery pack should be placed in dry and cool environment when not in use.
•
Do NOT immerse into water.
•
Do NOT install or disassemble the battery pack when it is live.
•
For optimum performance, you must charge at 14.6V. If you do not, you will not be able to
reach the full usable capacity of the battery.
•
To ensure the best performance of the battery when stored for a long time, the battery should
be charged and discharged every 3 months.
Disengaging the Protection
To disengage the BMS protection, follow the following steps:
1)
Disconnect the battery from the load and allow it to rest for 15-20min. If the problem persists, go
to the next step.
2)
Use a constant voltage (CV) charger to charge the battery for 5min ONLY. Constantly monitor its
voltage until it reaches the recovery voltage of 11.2V, then disconnect the CV charger. Do NOT let
it charge unsupervised.
Alternatively, you can use another 12V lithium battery with the same capacity to connect in
parallel with the battery and let them piggyback each other for approximately 12hours.
3)
To fully charge the battery, use a LiFePO4 charger.
