1 x KickAss 12V 140A Dual Sensing Voltage Sensitive Relay (VSR)

The KickAss 12V 140 Amp VSR detects voltage of both your start & auxiliary battery, & will engage or isolate depending on voltage level. Features dual sensing functionality & an override switch.
Featuring a massive 140 Amp current rating the KICKASS advanced Voltage Sensitive Relay (VSR) with override is a specially designed battery isolator which has the intelligent ability to sense both start and auxiliary battery voltages. This allows it to engage or isolate depending on each battery's voltage level. A huge advantage of this dual sensing VSR is that when the auxiliary battery is being charged by solar or an AC battery charger and it is above 13.2V the VSR will engage which will enable the starting battery to also be charged
In normal operation, this VSR will engage when the engine is running and the start battery reaches 13.2V. This will connect the start and auxiliary batteries enabling your alternator to charge them simultaneously. When the engine is not running there is no charge from the alternator to the battery and the voltage will drop. Once the voltage reaches 12.8V the VSR will disconnect from the auxiliary battery. This means that the auxiliary battery can NOT drain your start battery
A smart manual override switch is also incorporated and can be used to manually engage and connect the start and auxiliary batteries. This feature can be used when the start battery is low on charge and the auxiliary battery is still charged. Note: When the manual override feature is used the auxiliary battery takes time to charge the start battery it should not be used for instant starting
A remote switch can also be wired up to the unit to use the same feature
The KICKASS; premium VSR also features a tough case which is hermetically sealed against weather and corrosion making it suitable for 4X4, marine, truck and industrial applications. The unit can be easily mounted to the firewall under the bonnet or almost anywhere else as it has easy surface mounting with convenient cable entry and exit points
Key Features
- Charge you auxiliary battery without the risk of discharging your start battery
- Protects electronics on auxiliary battery circuit from engine start up spikes
- Fully automatic operation
- Override switch (engages relay regardless of sense voltage)
- Indication light wire (activates when VSR engaged)
- Override wire (activated by + feed for optional remote operation)
- Dual sensing - senses voltages of both start and auxiliary batteries
