This is selectable BMS for 3s or 4s or 5s batteries as shown in this image.

The 3 Series 40A 18650 Lithium Battery Protection Board 11.1V 12.6V 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

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).

PCB BMS 6 Series 22V 18650 Lithium Battery Protection Board is a 6-string 22V circuit power tool mostly used for solar lighting, for dedicated 18650 battery packs. It is designed for 3.7V 18650 models lithium batteries for charging, Protection from overcharge and over-discharge. Battery protection board, as the name suggests battery protection board is mainly rechargeable (Refers to the lithium battery) and protects the integrated circuit board. Lithium batteries (rechargeable type) need protection, which is determined by their own characteristics. As the lithium battery, its material determines itself can not be overcharged, over-discharge, overcurrent, short-circuit, or ultra-high temperature charge and discharge, so lithium battery lithium components will always follow A protective plate with a sampling resistor, and a current fuse.

This is a 12v Battery Protection circuit that Automatically Cut off the power supply of the source battery is full and starts charging again when the battery is low. When the battery voltage drops to about 11.5V (low voltage adjustable settings) when the protection board will automatically charge when the voltage reaches about 14.5V when the protective board power charger stops charging. To achieve automatic charging, automatic power off overcharge protection function. This board uses the special voltage control IC and the automobile special-purpose relay assembly, the volume is small, the electric current is big, the shutdown voltage is accurate and stable, the protection is thoughtful, the function is complete, the performance is reliable, can let you rest assured.
