Technical FAQs 4

Why do lithium batteries need a BMS?

The BMS prevents your lithium battery’s voltage from going too high (causing overheating and gas release) or too low (leading to permanent damage). Damage occurs if you overcharge (cell voltage gets too high) or over-discharge (cell voltage gets too low) a lithium-ion battery cell. Overcharging occurs when recharging exceeds a battery’s safe range.

What is a battery management system (BMS)?

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:

What is a BMS & how does it work?

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).

How many amps can a BMS control?

Our battery management system will not allow a current that exceeds 100 amps for more than 30 seconds and cuts off any surge over 200 amps after half a second. Please note that when you have two batteries in parallel, the surge levels are doubled. FAQ: Can the Battle Born BMS regulate amperage from an alternator?
