Product Specification
8/10
Battery pack should have sufficient strength and battery should be protected from
mechanical shock. No sharp edge components should be inside the pack contains the battery. 
9.2 PCM design
The overcharge threshold voltage should not be exceeding 3.95V. 
The over-discharge threshold voltage should not be lower than 2.3V. 
The PCM should have short protection function built inside. 
9.3 Tab 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 below is very
important to ensure battery performance. 
⑴
The electric iron should be temperature controlled and ESD safe; 
⑵ Soldering temperature should not exceed 350
℃
;
⑶ Soldering time should not be longer than 3s, keep battery tab cold down before next
soldering; 
⑷
Soldering times should not exceed 5 times; 
⑸
Directly heat cell body is strictly prohibited, battery may be damaged by heat above
approx. 100
℃.
9.4 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. 
9.5 Cells replacement
The cell replacement should be done by professional people. 
Prohibit short-circuit between cells’ Al package and exterior component.
