1 Pack toughness

Battery pack should have sufficient styength and the Li-Fe cell inside should be protected from mechanical shocks.

2 Cell fixing

The Li-Fe cell should be fixed to the battery pack by its large surface area.

No cell movement in the battery pack should be allowed.

3 Inside design

No sharp edge components should be insides the pack containing the Li-Fe cell.

4 Tab connection Spot welding is recommended for Li-Fe tab connection method.

Battery pack should be designed that shear force are not applied to the Li-Fe tabs.

If apply manual solder met hod to connect tab with PCM.below notice is very important to ensure battery

performance:

◆·The solder iron should be temperature controlled and ESD safe;

◆·Soldering temperature should not exceed 350℃;

◆·Soldering time should not be longer than 3s;

◆·Soldering times should not exceed 5 times,Keep battery tab cold down before next time soldrictly g;

◆·Directly heat cell body is strictly prohibited,Battery may damaged by heat above approx.100℃.
