Best Portable and Lightweight LiFePO4 Battery

This deep cycle BT Series(w/ bluetooth) 12V 120AH LiFePO4 battery are utilizie an intelligent battery management system(BMS) and bluetooth communication, the KHLiTech bluetooth series ensures you can monitor your battery status and localize any potential issues from a smart phone and tablet.

12V lifepo4 battery

The Lithium bluetooth series is a drop-in replacement for lead acid batteries, bringing with it all the benefits of Lithium Iron Phosphate(LiFePO4) Technology combined with a intelligent BMS. It delivers up to 50% saving in weight, 50% saving in space, a superior cycle life and charges a lot quicker.

At the heart of every Lithium bluetooth battery is an intelligent BMS that monitors and reacts to multiple voltage, current , and temperature events to maximize battery life, performance, and safety. Now with a free bluetooth APP available you can get instant access to the battery state of charge(SOC), voltage, cycles and a complete log on any potential issues.

Battery Management System BMS

All Kehengs LiFePO4 batteries come with an internal smart BMS.

BMS comes with overcharge, overdischarge, overcurrent, short circuit, temperature and other detection and balance functions to protect your battery from damage. If the BMS disconnects the battery due to temperature limitations, you must wait for the temperature to drop before reconnecting the battery.

If your device has parasitic loads, you may need to physically disconnect the terminals to reconnect the battery circuit. Note that while short circuit protection protects the cells of the battery, it can still spark and damage your cables or bolts, so it’s best to avoid short circuits.

Battery Management System BMS
A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger.
