How to Choose Single Cell BMS or Multiple BMS?
A single BMS focuses exclusively on one battery cell, while a multiple BMS can handle multiple cells, facilitating advanced features such as cell balancing and comprehensive battery health
Like lead-acid batteries, lithium batteries can be permanently damaged by overcharging, deep discharging, or extreme temperatures. That's where the Battery Management System (BMS) comes in. Often called the brain of the battery, the BMS ensures your batteries operate safely, efficiently, and for as long as possible. In this guide, we'll cover:
A 2S BMS is a Battery Management System designed for a two-series lithium battery pack. The “2S” refers to two cells connected in series, doubling the total voltage of a single cell. For example, two 3.7V lithium-ion cells in series produce a 7.4V nominal voltage and about 8.4V when fully charged.
A battery management system represents one of the most critical safety and performance components in modern energy storage applications. At its core, a BMS serves as an intelligent guardian that continuously monitors individual battery cells and the overall pack to prevent potentially dangerous situations while maximizing efficiency and longevity.
The current limits prevent the source (usually a battery charger) and the load (such as an inverter) from overdrawing or overcharging the battery. The BMS prevents your lithium battery's voltage from going too high (causing overheating and gas release) or too low (leading to permanent damage).
