Description:
18650 BMS 4S 40A Li-ion Battery Charger PCB though have high energy density and are light in weight, are very dangerous if abused i.e. if you overcharge or undercharge the battery or draw more current than it can provide then it can explode damaging the surroundings or even potentially harm the humans around. To prevent this from happening you should use your batteries with a protection board.
This 4S 40A Lithium-ion Battery Protection Board monitor protects three cells connected in series by monitoring the voltage and current in and out of the battery pack and if any unsafe condition happens then it will cut off the battery from the load or the charger. This can be used in any DIY project with low current like Arduino or Raspberry Pi-based projects, 3D printers, Quadcopters, Robotics applications, etc. As it can handle currents up to 40A you can also use it in slightly higher currents. This Board is suitable for 18650 cells having a nominal voltage of 3.6V or 3.7V, so it can provide a nominal voltage of about 14V and a maximum voltage of 16.8V.
