In this review we will be examining the 18650 Battery Protection Charger Board, also known as the 3Pcs 2S 3A Li-ion Lithium Battery 18650 Protection Charger Board BMS PCB Board.
This product boasts a high-accuracy voltage detection circuit, a high voltage device for charger terminal, and a built-in three-stage over-current detection circuit.

When put to the test the 18650 Battery Protection Charger Board proved to be a reliable and efficient option for charging and protecting Li-ion Lithium batteries. The high-accuracy voltage detection circuit and three-stage over-current detection circuit ensure that the battery is charged and protected with precision. Additionally, the MOS transistor adds control to the charging and discharging process. The over charge voltage range of 4.25-4.35V±0.05V and over discharge voltage range of 2.3-3.0V±0.05V provide a safe operating range for the battery.

To put it simply the 18650 Battery Protection Charger Board is a great option for those looking for a reliable and precise way to charge and protect Li-ion Lithium batteries. However, it is important to note that the maximum continuous current is limited to 3A and the max peak current is limited to 5A. While this may not be sufficient for some high-powered devices, it is suitable for most applications.

In conclusion the 18650 Battery Protection Charger Board is an excellent choice for those looking for a reliable and precise way to charge and protect their Li-ion Lithium batteries. Its high-accuracy voltage detection circuit, three-stage over-current detection circuit, and MOS transistor control make it a standout option in its category. As long as the maximum current limitations are not exceeded, we highly recommend this product for anyone in need of a battery protection charger board.
