Mastervolt BI 703 Battery Isolator

Model: 83007030
  • Battery isolators that divide your charge current with a minimum energy loss.
  • The Charge Mate for connecting and/or disconnecting two batteries.
  • Battery Watch for monitoring the condition of your batteries (also usable as main switch).

Onboard systems usually consist of two or more batteries that function independently when powering the 12 or 24 V consumers. These batteries require independent charging with reliable battery isolators or battery combiners.

Mastervolt’s BI battery isolators are based on conventional diode technology. The diode voltage drop (ca. 0.6 V) can be compensated for by adapting the output voltage of the connected charger or alternator. Mastervolt Mass battery chargers and Alpha Pro charge regulators are standardly equipped with automatic voltage drop compensation.

The Mastervolt BI battery isolators are compact and fully solid state, preventing wear. The weight varies from 580 to 1300 grams.

Completely corrosion-proof material with aluminium heat sinks. The electronic components are encased in synthetic materials, the BI models have molded diode splitters.

The synthetic end plates feature connection lugs, the solid bolt connections with nuts and locking rings ensure easy installation.

Great size and warm but didn't feel as luxurious and soft or thick as I thought
Color: Shadow Grey, Size: Twin/Twin XL
This blanket is not quite at fluffy or thick as I would have wanted. It feels thin but soft. It does keep me warm though and it's the perfect size to have multiple people cuddle on the couch while watching a movie?

Shed Really Bad
I love tge feel of these blankets. However, they shed really bad. We have blanket fuzzy embedded in all of our clothes from these blankets. I have washed them several times.

Light, soft, comfy, cozy, but not hot!
Color: Dark Sage Green, Size: King/Cal King
I've been looking for a blanket to replace a Berkshire blanket called "Perfect Touch" I've had since 2009 and this is it! I wanted something light weight, comfy, and cozy that doesn't get so hot like many do. When I first got it i thought it might get hot because its soooo fluffy, but it doesn't. I know some have complained about shedding or it coming apart after washing. I've washed it several times, following the washing instructions provided and haven't had any issues at all, really nice quality for the price! Oh, and its cat approved too.
