The main function of 22.2v lithium battery protection board ensures the safe and normal operation of the battery, as follows:
- Overcharge protection: usually charging cut-off protection voltage 25.2±0.025V, once the charging cut-off voltage is reached, the protection circuit will be disconnected.
- Over-discharge protection: usually over-discharge cut-off voltage voltage 18±0.025V, once the over-discharge cut-off voltage is reached, the protection board will be disconnected.
- Short circuit protection: Once short circuit occurs, the protection board will disconnect the circuit automatically in a few milliseconds.
- Over-current protection: once the protection board reaches the set current value, the protection board will automatically disconnect.
The mainstream terminal models of 18650 battery packs are as follows:
- JST-XH, JST-PH, JST-SM
- Molex 51021, Molex 5557, Molex Micro-Fit 3.0
- Amphenol AT Series, Amphenol PT Series
- TE AMP Superseal, TE Micro MATE-N-LOK
Lithium-ion battery production process
#1 Cell Selection
Select the number of 18650 cells or LiFePO4 cells we need. Ensure they works fine.
#2 Battery Sorting
Make sure that the capacity, voltage, and internal resistance of the selected cells are consistent.
#3 Arrangement & Assembly
Combine the required battery modules in a series-parallel manner.
#4 Spot Welding
The positive and negative terminals of the battery are connected via nickel tabs to form the desired capacity or voltage.
#5 Mounting Protection Board
Connect the protection board on the battery pack to ensure that its overcharge, overdischarge and short circuit protection functions properly.
#6 Packaging & Aging
Wrap the battery pack in a PVC or metal casing while charging and discharging to activate the battery pack performance.
