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.

Nice look, good value
Size: Large, Color: Grey Mixed(quarter Socks)
Fit great. Cushion on bottom is exactly what I wanted, top and ankle sections are much thinner as I wanted, so as not to be bulky. Expect they will well for walking and hiking. They did wash well although did lose some of the softness but did not shrink.

Nice but issue from manufacuter.
Size: Large, Color: Ivory/Beige/Pink, Size: Large, Color: Ivory/Beige/Pink
I received the 6 pack of socks to give as an Easter present. The socks were great colors, soft, and fit well. Will be a little warm during the hotter days. Unfortunately the yellow pair came with a hole already at the toe area.

My dog LOVES this tiny tug ball
Size: Medium(6")
A lot smaller than I was expecting.. BUT my dog doesn’t mind at all. She seriously loves this thing. It goes flat fairly quickly, but that’s what happens with all of her soccer balls, no matter the size. She’s a pitbul catahoula mix and has a strong bite. Considering my dogs chewing abilities, I’m fairly impressed by the durability of the ball, though she chewed through all but one of the rope handles in about 2 seconds. All that said, it’s one of her favorite toys(she’s 13 years old)
