Lithium ion or polymer cells need to be protected from under or over discharging, which can be really bad. This is done by a battery management system/board, or BMS. It's a device that combines battery protection for multiple cell batteries like we are building. It’s called a battery management system or BMS for short.
That’s why these batteries should go together with a battery management system unit or BMS. This will control the voltage and current from the battery and keep them safe. Usually, the nominal voltage of a LIPO battery is 3.8 volts and 4.2V when fully charged.
Solder the positive (red wire ) from the DC jack and Rocker switch to the P+ of the BMS, negative wires from the DC jack, and Battery level indicator to the P- of BMS. Then apply hot glue at the base of the battery compartment, then secure the battery pack. So that it will seats firmly and prevent any loss of wire connections.
But unlike other types of batteries, for example, lead-acid or nickel batteries, lithium-ion batteries are very demanding for the charger parameters. Battery management system lithium ion batteries (Like 18650 Batteries) is very important. If you don’t control the process of charging and discharging of Lithium-ion batteries, they will fail soon.
Generally cells are salvaged/second hand, and typically use Lithium 18650 cells. Lithium batteries need to be kept at the same voltage level across a parallel pack. This is done by balancing each cell in the pack to raise or lower its voltage to match the others.
The battery cells can swell and even explode from overcharging, and a deep discharge can make the battery fail. That’s why these batteries should go together with a battery management system unit or BMS. This will control the voltage and current from the battery and keep them safe.
