FAQ
1-Q/ What is the cut-off voltage of a lithium battery?
A/ Based on your product requirements, the battery can be configured accordingly.
2-Q/Can a lithium battery explode?
A/ Normally not, thanks to the protection circuit and being memoryless
3-Q/ What is the reason for the swelling of a lithium battery?
A/ In a case the skin of the battery is damaged, it will cause the air to go into the battery, so it will swell up.
4-Q/ Whatâ??s the life cycle of a lithium battery?
A/ The battery can be charged up to 500 times with still 80% of energy left in.
5-Q/ What is the storage temperature of a lithium battery?
A/ 0 to 45 degrees
6What is a lithium polymer battery?
Lithium-polymer battery is a type of lithium-ion battery, also known as soft-pack battery.
7Is it possible to notice a problem on a polymer lithium battery just by looking at the appearance?
Yes, if there is no noticeable flaw, cracks, rust, leakage or other defects then the battery is in fine state
