For making the battery pack we require a 4S 40A BMS module, 4 Li-ion cells, nickel strip, DC female barrel jack, and cell connecting brackets. Apart from these, we will also connect a voltmeter, and a bulb to show the pack in operations, which will be connected through a switch.
To build a 12V battery pack, you will need: 18650 Cells: At least three cells connected in series. Battery Management System (BMS): To protect against overcharging, over-discharging, and short circuits. Nickel Strips: For connecting the cells. Spot Welder or Soldering Iron: To secure connections.
To build a 12V battery pack with 18650 cells, connect four cells in series (3.7V each) to achieve approximately 14.8V nominal. Use appropriate battery management systems (BMS) for safety. Ensure balanced charging and consider using protective cases for safety and longevity.
Designing a simple battery pack and connecting it with a cost-effective protection circuit to make a robust battery pack that can be used to power RC cars, quadcopters, or other different gadgets running at 12VDC.
Connect the BMS according to its wiring diagram: Attach it to the terminals of your battery pack. Ensure that it is correctly positioned to monitor each cell’s voltage during charging and discharging. 6. Insulate and Secure Your Pack
The Li-ion battery pack circuit diagram consists of three basic components: the battery cells, the PCM, and the load. The cells are the primary energy source for the system, providing the energy for the load. The PCM is responsible for monitoring and protecting the battery from overcharging, over-discharging, and excessive temperature.
The solution is simple – either connect a charger externally, or short-circuit the OUT- and B- with something metal (I often add an external button), but it''s annoying to deal with.
