IMAX B3 AC Compact Balance Charger in Pakistan

HX-4S-A20 4S 20A 14.8V BMS For Lithium-Ion 18650 Cells Battery Protection Board A battery management system (BMS) is an electronic regulator that monitors and controls the charging and discharging of rechargeable batteries. Battery BMS protection boards are the brains behind battery packs. 20A 4S BMS manages the output, charging, and discharging and also provides critical safeguards to protect the batteries from damage. 18650 protection circuit Board is a high-accuracy voltage detection circuit. The 20A protection board can be used for lithium-ion Phosphate batteries, Low power inverters, massager battery packs, electronics.

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
