Note:

1.Test results will be affected by test conditions (eg, temperature, wire loss, test equipment, test parameters, etc.), please perform multiple tests and take the average of the results to reduce the deviation.

2.At a temperature of 25°C, the deviation between the pure resistance discharge test result and the nominal data is controlled within ±10%, which is normal.

3.Cycle Life:More than 1000 cycles, Capacity and performance will decrease as the number of cycles increases.

24v lithium ion battery for electric wheelchair


Test Report: UN38.3, MSDS

Certification: UL,CE 


FAQ:

Question: Is PCM or BMS necessary for lithium battery? If yes, why?

Answer: Yes, it is necessary for lithium battery. Since lithium battery is hazardous goods and may cause leakage or fire if misused. PCM and BMS is a necessary method to protect the battery from over-charge, over-discharge, over-current, over-temperature and short circuit. BMS also has functions of SOC(state of charge), SOH(state of health), communication and LCD screen etc.


Question: What are the possible reasons if the rechargeable battery or rechargeable battery pack can not be charged?

Answer: There is battery with zero voltage in the battery pack. 

Or there is wrong connection inside the battery pack. 

Or there is abnormal electronic components or PCB inside the battery pack. 


Question: What will happen if the batteries with different capacity are packed together?

Answer: If the batteries with different capacity or new and old batteries are used together, leakage, zero voltage and so on might happen. If the batteries are rechargeable and are being charged, some batteries is overcharged and other batteries is not in full charged state. During the discharge, some batteries can not discharge fully and other batteries might over discharge. This way, the battery will be damaged.
