How we make 48V 50Ah lithium battery
- Select A-class quality LiFePO4 battery cells, 3.2V 50Ah battery.
- Connect 16 cells in series to achieve 58.4V using a welding machine to connect the positive and negative terminals into a battery pack module.
- Install a PCM (Protection Circuit Module) and connect it to the battery pack, ensuring it has overcharge, over-discharge, over-current, and over-temperature protection functions.
- Enclose the assembly in a case, typically using a sheet metal enclosure.
- Install output terminals, usually M10 screw terminals.
- Insulation protection: Pay attention to insulation and waterproofing, generally rated at IP65.
- Perform one charge and discharge cycle, checking voltage, capacity, internal resistance, and charge/discharge curves.
Lithium-ion battery production process
#1 Cell Selection
Select the number of lithium iron phosphate battery 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 ABS or metal casing while charging and discharging to activate the battery pack performance.
