8S 20A BMS LITHIUM 18650 BATTERY CHARGING BOARD

Overview of this 8S 20A BMS 18650 Battery Charging Board

Introducing Roboway 8S 20A BMS 18650 Battery Charging Board at best price in India. This Battery Management System (BMS) specially designed for 8 series (8S) lithium-ion 18650 batteries. It helps in keeping the batteries safe and balanced while charging and discharging.  It supports up to 20A continuous current, which means it can handle medium to high power loads like e-bikes, DIY battery packs, solar storage, and other electronics without overheating.

This board automatically stops charging when any cell reaches its safe voltage limit, preventing the battery from overcharging and getting damaged also it cuts off the load when any cell voltage goes too low, protecting the battery from deep discharge that could reduce battery life. The BMS instantly disconnects the battery if it detects a short circuit or if the current goes higher than safe limits, ensuring both user and battery safety.

Features

Supports 8S Lithium Battery Pack (8 Cells in Series) – This BMS is designed to manage 8 lithium cells connected in series, making it suitable for 24V battery packs used in e-bikes, solar projects, or power banks.

20A Maximum Continuous Current – It can handle up to 20A continuous current, which ensures stable power delivery for medium to high load devices without overheating or shutting down.

Overcharge Protection – The board automatically cuts off charging when a cell reaches the maximum safe voltage (around 4.2V), preventing battery damage and extending battery life.

Over-discharge Protection – It stops the battery from discharging below the minimum safe level (around 2.5–3.0V per cell), which keeps the cells safe from deep discharge that can permanently harm them.

Short Circuit Protection – If there is an accidental short circuit, the BMS instantly disconnects the load, protecting both the battery pack and connected devices from serious damage.
