2S Lithium-ion Battery Protection BMS Board - 7.4V 3A

Lithium-Ion batteries though have high energy density and 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 surrounding or even potentially harm the humans around. To prevent this to happen, you should use your batteries with a protection board. This 2S Lithium-ion Battery Protection Board monitor protects two 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 where the current does not exceed 3A like Arduino or Raspberry Pi based projects, 3D printers, Robotics, etc.

Product Description

To connect your two cells of nominal voltage 3.7 V to the protection board, you need to first connect them in series and then connect the positive terminal to the B+ and negative terminal to B- and common terminal between the two cells to Bn. To connect the load or charger to this board, connect positive terminal to P+ and negative terminal to P-. make sure the two positive and negative wires do not get shorted.
