24V 4Ah deep cycle battery manufacturing
How we make 24V 4Ah lithium battery
- Matching set of high quality LiFePO4 cells. For a 24V 4Ah battery, you will need 8 cells in series, each with a nominal voltage of 3.2V and a capacity of 4Ah.
- Series the cells in series positively to each other to achieve a nominal voltage of 25.6V. Connect the batteries using nickel strips and a spot welder.
- Install a battery management system (PCM) to prevent overcharging, over-discharging and short circuit protection. Select a BMS with a nominal voltage of 25.6V and a continuous current of at least 100A.
- Solder the protection plate in the P+,P- position.
- Sheet metal enclosure to house the battery and BMS. cells and batteries need to be insulated.
- Install terminal connectors, fuses and any monitoring displays.
- Perform initial charge/discharge and testing to verify proper operation and capacity.
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.
