How long do the lithium batteries charge for the first time to activate the lithium battery?
How to identify difference of battery ?
Q: Is PCM or BMS necessary for lithium battery? If yes, why?
A: 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.
Q: What are the possible reasons for zero voltage or low voltage of the battery pack?
A: Short circuit or open circuit of the connector or wrong connection, desoldering or cold solder joint between the batteries and lead, wrong connection between the batteries.
Q: What are the possible reasons if the rechargeable battery or rechargeable battery pack can not be charged?
A: The battery is zero voltage or there is battery with zero voltage in the battery pack.
There is wrong connection inside the battery pack.
There is abnormity of electronic components and/or PCB inside the battery pack.
There is failure in charger.
Outer element causes the charging efficiency to be too low, such as extremely low or high temperature.
Q: What will happen if the batteries with different capacity are packed together?
A: 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.
Q:Can I use Lithium batteries mixing with other battery types?
A: If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics of voltage, capacity, etc , may cause over-discharge of the battery which is exhausted first, leading to swelling, bursting or fire.
Q: How do I make the payment?
A: We accept L/C, D/A, D/P, T/T, Western Union, MoneyGram, Alipay, WeChat pay, Paypal.
