Mastervolt BI 702-S Battery Isolator

Model: 83007021
  • 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.

Inexpensive walls.
Color: Grey, Size: 34" - 3 Panel, Color: Grey, Size: 34" - 3 Panel
We had a hot request for a workstation in the warehouse with some privacy. These have worked great. Easy to assemble. They are lightweight and stable. This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.

Great privacy screen
Size: 6 Panel-119"W, Color: Beige
I have a studio apartment and the bathroom is in my bedroom. I bought this to section the area off so guests can use my bathroom without seeing my entire bedroom. This is perfect for that! It looks very nice and offers alot of privacy. The screen is fabric and good quality! I’m a middle aged woman and put it together myself in about 2 hours. Love this!!!

Nice divider 6 panel with wheels.
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The wall works great , and I put it together by myself. I only gave it what I did because I have to move one or two of the panels on one end around a bit daily to make an opening to pass through. I find I have to check the screws that hold those legs/feet on frequently and retighten them. Beyond that everything was pretty good quality. (I ended up magnetizing an Allen wrench to one of the feet.) I also put on motion lights to the rollers so you’ll see them and don’t trip.
