Bluetooth® monitoring app

This battery give you the capability to easily monitor its key data wirelessly, via Bluetooth® connection. You can access this feature by downloading the Hardkorr Battery app which is available for iOS® and Android® devices. With the app you can view:

KEY INFORMATION
State of charge, current voltage, available capacity, status, health.

DETAILED INFORMATION
Current voltage, net current in/out, status, cycle life, temperature.

CELL STATUS
Current voltage of each cell to ensure they are balanced.

CONTACT DETAILS
Our website, address and email in case you have a question or problem.
The app also records a log of any instances where a BMS protection circuit is activated, including over-charge, over-discharge, under-voltage, over-current and over-temperature. You can find it by pressing the shield icon in the top-right corner of any screen.

 

Handy remote reset switch

The Battery Management System (BMS) inside all lithium batteries contains a protection circuit which trips if the voltage drops below a certain setpoint. In the case of Hardkorr batteries, it is set at 10.0V. This circuit prevents damage to the battery by putting it into a ‘sleep’ mode until it is reset.

In the past, resetting the battery after the over-discharge protection was activated was not easy. Whilst some battery chargers do contain a “wake-up” function, most people had to resort to applying a constant voltage above 12V across the terminals using jumper leads or home-made wires. This was fraught with danger; damage to appliances or the battery were not uncommon.

Our batteries provide an easy solution to this problem; simply connect our included remote reset switch to the socket on the top face of the battery and hold down the button for 5 seconds, and the over-discharge circuit will reset itself. The button can also be flush-mounted into your 12v setup if desired.

 

Oversized Terminals

Direct +/- connection to the battery. The oversized terminals not only simplify installation but also enhance the overall reliability of your power source, providing peace of mind during off-grid adventures.

ATTENTION: This battery is not suitable for under bonnet use.

* Note on discharge current: if you connect multiple batteries in parallel, the maximum discharge current is multiplied by the number of batteries in the array. For example, if you connect two of these batteries in parallel you can discharge at up to 500A.
