Product Description

Sterling LiFePO4 12V 200Ah Lithium Iron Phosphate Battery with BMS & Safety Shutdown – AL12200

Sterling Power 200Ah 12v Lithium Iron Battery with Battery Management System and Safety Shutdown and Bluetooth functionality.

The lowest cost battery by far – When you take into account how many conventional batteries you will destroy in operation to match the performance and cycle span of a lithium. A lithium battery is by far the lowest cost per cycle of any battery.

For many years people have wanted a simple, easy, solution to installing lithium batteries in the automotive industry: Including commercial vehicles, campervans, caravans, military, police and ambulances. However, due to the specific incompatibility with charging voltages and currents on board the vehicles and the requirements of the battery, the two things simply could not be safely brought together without a very elaborate intermediary system linked into a BMS for the lithium battery.

All this is not gone; today we have lithium batteries with built in BMS and automatic shutdown systems that take care of the extreme faults that may be presented to a lithium battery. With the simple addition of a Battery to Battery charger the correct voltage and current profile is provided to the battery from the vehicle’s alternator with no integration fuss. This means, when your alternator voltage is low, the battery to battery charger increases the voltage and when your alternator’s voltage is too high the battery to battery charger decreases it. Also, when you have too much current, the battery to battery charger reduces the current, thus, presenting the lithium battery with its ideal safe voltage and current requirements. This has never been so important than with the modern Euro 5/6 vehicle applications. The first, all in one – simple to install – package that removes all fears with this technology for application on vehicles.

Lithium batteries are also less than half the weight of the equivalent lead acid. This means that the available energy per weight ratio is 4 times better with lithium batteries.

Bluetooth App

Download the Lithium Battery Bluetooth Instructions Datasheet.

Features of the app are:
1) Terminal voltage display.
2) State of charge of battery display (based on voltage).
3) Battery status – need charge, low power, normal – with colour coordination

1) to download the app, go to the website:

2) On your mobile phone / tablet, click on this link. This shall download the .apk file to your device.

3) If installed successfully the app should appear on your homepage.

4) When app is opened, the ‘Device Scan’ page appears. Here you have to select the device that matches the serial number on the top of the lithium battery. It should look like B0000000xx. Once located, press to open. If you have multiple batteries the app shall detect multiple entries / serial numbers. Simply correspond the serial number to the battery you wish to monitor.

5) When you have clicked on the correct serial number the Battery Monitoring System page opens. The SOC (state of charge) image is a crude representation of the battery capacity % based purely on the terminal voltage of the battery. Therefore, this SOC figure shall only ever be accurate when the battery is neither being charged nor being discharged.
