1s BMS 3a 3.7v Battery Protection Board With Welding Strip For 18650 Battery In Pakistan

The 4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module comes with recovery function – AUTO Recovery and Integrated 10 low load resistance MOS tube. It provides a continuous discharge of 40A, 100mA balanced current, for electric drill/sprayer/LED lights/low power inverter. (If the cooling environment is not good, please reduce the load current use).The Scope of Nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, a polymer lithium battery) where Charging voltage can be range between 16.8V to 18.1V The board operates smoothly with Continuous charge current of (upper limit): 20A. The balanced version is suitable for starting current below 80A, power 135W below the drill (with balance).

BMS (Battery Management System) – a battery management system that is designed to monitor the status of batteries, control the process of charging/discharging the battery, etc. This Module has Protection against short circuits and protection against over-discharge. The module is to turn off the power supply for the batteries when reaching the maximum capacity of all batteries (balancing). The battery charge is switched off when the voltage reaches cell cutt of voltage and the discharge when the voltage drops to 2.3 – 3.0 V.
Five, four, or three batteries  can be connected to this module at the same time. By default, the circuit is assembled to work with 5 batteries. To switch to a 3 or 4 battery mode, it is necessary to solder a jumper or SMD resistor marked “0” in the appropriate places
