KickAss 12V 140A Dual Sensing Voltage Sensitive Relay (VSR)
Exactly what I was after, and at a great price. Found it really easy to install and now I can ensure I dont drain my battery when powering the Engel in the back of the 4WD. Ordering and delivery was really easy as well. Would recommend.

KickAss 12V 140A Dual Sensing Voltage Sensitive Relay (VSR)
Easy to install and great concept (two batteries in a boat with electric motor .main battery and starter battery for petrol engine). However, when using then elctric motor the switch has been 'stuttering (on-off-on-off-on-off....) as voltage drops. Also has water condensation under the plastic cover for the override switch. Will be asking for a replacement and see if its just bad luck/once off.

All Spark, No Fire! 🔥
The Kickass VSR does exactly what it promises—keeps my battery setup in check without catching fire!! Reverse charging? Nailed it. Car still in one piece? You betcha.
So if you're looking for a VSR that works as advertised and doesnt melt your 12v system, this is the go. Bravo, Kickass VSR! 👏🚗🔋

KickAss 12V 140A Dual Sensing Voltage Sensitive Relay (VSR)
Bought the 140 Amp Dual Sensing Voltage Sensitive Relay 6 or 7 years ago. works fantastic. never had a problem with it,
Other then recently the override switch has broken, (not from over use) but i will be able to use the override wire to an external switch in a more accessible location.
I did have a stat battery die in the middle of Simpson Desert, so happy it had the override feature. so was able to keep it on and start run the patrol of the "house batteries" for the rest of the trip.

It doesn't fit a 2024 Mitsubishi Pajero Sport. There is not enough room to connect it to the battery.

KickAss 12V Smart Battery Guard (VSR & LVD in One)
Very handy and compact component to have in my 12v system. Literally took me one minute to install and the app is convenient to set-up the cut-in and cut-off voltage limits as well as view the health of my crank battery. I run all my accessories from the LVD while I'm camping so it's handy to know I don't need to stress about a flat battery.
