Overview of this Daly 7S 24V 20A BMS For Lithium Battery
Introducing Roboway Daly 7S 24V 20A BMS for lithium-ion battery at best price in India. This is a Battery Management System (BMS) specially designed for 7 series (7S) lithium-ion batteries, which gives a total working voltage of around 24V. It helps keep the battery safe and efficient. It can handle up to 20A continuous discharge current, which means it supports medium-power devices and projects without overheating or damaging the battery.
The BMS stops the battery from charging too much, preventing cell damage and making the battery last longer. It also prevents the battery from being drained too much, which is important because deep discharge can permanently reduce the battery’s life. Some Daly BMS boards also include a cell balancing feature, which makes sure all the cells charge and discharge evenly. This helps improve battery performance and ensures every cell works at the same level.
Features
Supports 7 Series (7S) Lithium-Ion Batteries – It is designed to work with 7 cells connected in series, giving a total system voltage of about 24V.
20A Continuous Discharge Current – The BMS can handle up to 20A of continuous current, making it suitable for medium-power applications like e-bikes, solar storage, and DIY projects.
Overcharge Protection – It automatically cuts off charging when the battery reaches the maximum safe voltage, which helps to prevent damage and increase battery life.
Over-discharge Protection – Stops discharging when the battery voltage gets too low, protecting the cells from deep discharge which can permanently harm them.
Overcurrent / Short Circuit Protection – This BMS gives safety by cutting off power during very high current flow or short circuit, preventing overheating or fire risk.
