4S 40A Lithium Battery Protection Board Bms for 3.7V NMC cells

Overview of this 4S 40A Lithium Battery Protection Board Bms for 3.7V NMC Cell

Introducing Roboway 4S 40A Lithium Battery Protection Board at best price in India. This BMS is designed to work with 4 series (4S) lithium batteries, which means it connects 4 individual 3.7V NMC cells in series to make a pack of about 14.8V nominal voltage. Its main work is to keep your battery pack safe by protecting against overcharging, over-discharging, overcurrent, and short circuits, which can damage the cells or reduce their life.

It can supports up to 40A continuous discharge for making it suitable for medium to high-power applications like e-bikes, scooters, solar storage, DIY power banks, or portable tools. This BMS also balances the voltage of each cell during charging, so all 4 cells stay healthy and equal, which increases the lifespan of the battery pack.

This 4S 40A Battery protection for 3.7V NMC cells ensure optimal functions even in harsh condition. It deliver precise balance charging and robust protection to extend battery life. This board is important for anyone who need to maintain a stable and reliable lithium battery system. Trust Roboway for cutting edge technology and superior battery management solution.

Features

Overcharge Protection: This 4S 40A lithium battery protection board prevent from overcharging by cutting off the circuit at excessive voltage level. It ensures the safety and long life of the lithium battery.

Over discharge Protection: This board disconnect the load when the battery voltage drops too low. This feature protects the cells from deep discharge damage.

Overcurrent Protection: It includes an overcurrent protection mechanism to prevent damage from high current surges. This keeps the battery and connected devices safe.

Cell Balancing: Integrated cell balancing ensures each cell in the battery pack charges evenly. This optimizes battery performance and extends overall lifespan.

Temperature Monitoring: This 4S 40A Lithium Battery bms board feature temperature monitoring to detect overheating condition. It prevents thermal damage by cutting off power if temperature exceed safe limit.
