1 Cell 18650 Lithium-ion battery protection Board

Description

The 3.7V 3A li-ion BMS PCM battery protection board is designed to safeguard 18650 lithium-ion batteries. It incorporates a high-accuracy voltage detection circuit and supports charging and discharging control through a MOS transistor. The board includes a built-in three-stage over-current detection circuit, protecting against over-current conditions and load short circuits. It offers overcharge protection with a limit of 4.25V ±0.05V and over-discharge protection at 2.54V ±0.1V. The maximum continuous charging current is 2A, while the maximum continuous discharging current is 3A.OKY3399-1
