Customized LiFePO4 /LI-ion battery pack + charger + BMS. The BMS (Battery Management System that can monitor and equalize each single cell during charge & discharge ) .
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℃.
