3S 11.1V 18650 Lithium Battery Polymer Battery Equalizer Board

Overview of this 3S 11.1V 18650 Lithium Battery equalizer board

Introducing Roboway 3S 11.1V 18650 Lithium Battery Equalizer Board for maintaining battery balance at best price in India. This board helps to keep all 3 cells (3S) of an 11.1V lithium battery at the same voltage, so that no cell is overcharged or undercharged. This makes the battery safer and lasts longer. The equalizer works automatically while charging or discharging, so you don’t need to adjust anything manually.

It is specially designed for 3S 11.1V Lithium Battery equalization, this board is important for battery health management. It actively prevent overcharging and discharging issues that can damage cells. This 3S 11.1V Battery Equalizer Board is ideal for electric vehicle, DIY project, and energy storage systems. Enhance your battery lifespan and reliability with this versatile 3S Equalizer Board solution.

Features

Automatic Cell Balancing – It balances the voltage of each battery cell automatically so that no cell gets overcharged or undercharged, which helps increase the battery life.

Supports 3S (11.1V) Batteries – It specially designed for 3-cell lithium batteries (18650 or polymer type), making it ideal for 3S battery packs.

Improves Battery Efficiency – By keeping all cells at the same voltage, it ensures better charging and discharging performance for stable power output.

Protects from Voltage Difference – Prevents high voltage differences between cells, which can otherwise damage the battery or reduce its performance.

Easy to Use – Just connect it to your battery pack and it works automatically without needing extra setup or programming.
