Polymer Lithium-ion battery
8. Cell packing and fixing
Notice of designing battery pack:
Battery pack should have sufficient strength and battery should be protected
from mechanical shock. No sharp edge components should be inside the pack contain the battery.
PCM design
The overcharge threshold voltage should not be exceed 4.25V.
The over-discharge threshold voltage should not be lower than 2.3V.
The PCM should have short protection function built inside.
Cell connection
Ultrasonic welding or spot welding is recommended to connect battery with PCM or other parts.
If apply manual solder method to connect tab with PCM, the notice bellow is very important to ensure battery
performance.
1. The electric iron should be temperature controlled and ESD safe.
2. Soldering temperature should not exceed 350ºC.
3. Soldering time should not be longer than 3 s, keep battery tab cold down before next soldering.
4. Soldering times should not exceed 5 times.
5. Soldering spot location should be away from the t a b film to ensure the sealing of the tab film.
6. The soldering spot should be smooth should be no acumination.
Cell fixing
The battery should be fixed to the battery pack by its large surface area. No cell movement in the battery pack
should be allowed.
Cell replacement
The cell replacement should be done by professional people.
9. Warranty
The warranty is specified in our warranties section of
Terms of Sales
. If the product is to be stored for more than
three months it is necessary to perform the appropriate maintenance to ensure the good condition of the batteries.
Consult our annex to the
Terms of Sales
