Easy to use battery isolator

This battery isolator is easy to install and the instructions are very clear. It connects the trailer and truck battery when the trailer battery voltage is above 12.8 VDC and disconnects it from the truck battery when the voltage is below this value. So far it works without problems. Worth buying!

Pros
  • Dope 🔥
Cons
  • I'll write later

One of the best inventions.

This item works great and has saved my ass a few times! This isolates my "expensive" electrical components from the main electrical system of the car. So if these items (can) destroy the secondary battery, I can still start my car and the isolator, and then let the car charge my secondary battery. Thanks for saving my ass leaving the inverter on overnight lol!

Pros
  • Perfect for outdoor activities
Cons
  • Secret

Works as advertised

Based on the instructions and information on the motherboard the installation was easy and I'm sure I know what's going on and why. The instructions are almost in English, and the mainboard will tell you which contact is suitable for which battery. The Revain's advertised wattage at 140A didn't match the motherboard's advertised rating of 80A. Still good enough for my needs, but consider buying an oversized one for your own needs. The materials seem to be good. For 80 amps I need 4-6 AWG wire…

Pros
  • Excellent design
Cons
  • There are cons

The 2nd battery does not help to start the car with this device.

There was no point reading the description that this device doesn't allow your second battery to start the car unless you go to the installation site of the device and press a few buttons on the device. Also the 6mm mounting posts seem quite small, it's difficult to find connectors for wire sizes that can handle 140A current under 8mm. This unit is RV compatible, but I no longer have an RV. I think I'll save and use if I get a trailer with a winch in case I leave the trailer hooked up just use…

Pros
  • Still happy
Cons
  • Useless features
