1S 3A BMS Module / 3.7V Lithium Battery Protection

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 1S Lithium-ion Battery Protection Board monitor and protect a cell by monitoring the voltage and current in and out of the cell 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. It is very suitable for 18650 cells which are generally used in these applications.

Specifications

• Short circuit protection
• Overcharge protection
• Over-discharge protection
• Overcurrent protection
• Over Discharge Detection Voltage: 3.0V
• Maximum Working Current: 3A

Product Description

To connect your cell of nominal voltage 3.7 V to the protection board you need to 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.
