Description
KickAss 12V Battery Guard
The KickAss Battery Guard can disconnect any non-essential loads from the battery (Low Voltage Disconnect). Or it can be set as a Voltage Sensitive Relay (VSR) and connect the main battery to the auxiliary battery. Fully customisable Bluetooth app, manual override switch, LED diagnostics mode.
Set As Low Voltage Disconnect or Voltage Sensitive Relay
Have the flexibility to set the battery guard to suit your needs. Set the Battery Guard as a low voltage disconnect (LVD) or a voltage Sensitive Relay (VSR). If upgrading your vehicle and no longer need an VSR simply change the functionality from a VSR to an LVD via the app.
Battery Guard - Low Voltage Disconnect
Protect your battery from accidental over discharge with Battery. Simply install the devices onto your auxiliary battery and set the voltage and once it reaches the set voltage it will disconnect all loads, preventing damage to your battery from over discharge.
Battery Guard - Voltage Sensitive Relay
Allows both your main and auxiliary to be charged at the same time from your alternator. Perfect for vehicles that do not have smart alternators
Fully Customisable Settings Within Bluetooth App
With the fully customisable settings within the handy Bluetooth app, you can control and set all of your battery guard preferences with ease. Simply connect to the battery guard via Bluetooth and set the setting as a VSR or LVD.
Set cut in/out voltages & cut in/out timeout
Manual override switch via App - great for emergency situations. Using the bluetooth app, you can set the timer before your smart guard cuts out once it goes below cut out voltage, great for high load application such as an inverter where voltage may momentarily drop below the cut out voltage but you still want your battery to remain connected.
Manual Override Switch
Have full control at your fingertips with the Manual Override Switch. Run it into your dashboard allowing you to manually override the battery guard settings. Perfect for activating the VSR to jump start your main battery from your auxiliary battery.
Please check your battery specifications before attempting to jump start.
LED Diagnostics
Get full diagnostics at a glance from the battery guard or LED light in Manual override Switch:
1 Short Green LED Pulse Every 4 seconds - Battery Voltage is above Cut-in Voltage and Battery Guard is engaged
1 Short Blue LED Pulse Every 4 Seconds - Battery Voltage Below Cut-out Voltage and Waiting for pre-set timeout to expire before battery guard disconnect from starter battery and load Terminals
1 Short Red LED Pulse Every 4 Seconds - Battery Voltage is below the cut-out. Battery guard is Disengaged and load terminals are disconnected.
100A Continuous Max Discharge
With a maximum 100 Amp continuous discharge, the battery guard is perfect for all common 12V applications with up to 300A peak current for emergency jump starting. 1200W is the maximum sized inverter that can be run with the Battery Guard
Easy Installation
Installing your battery guard onto your auxiliary battery has never been easier. The battery guard has been designed to fit directly onto the terminal of your battery so no additional cabling or mounting hardware is required.
