Model: 83116035
  • Battery Mate battery isolators with a negligible voltage drop
  • Clear monitoring
  • Robust and durable
  • Fast installation

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.

While BI battery isolators are conventional diode splitters, the Battery Mate’s technology is electronic and includes mosfets (transistors). Its components compensate for the voltage drop and ensure that charging continues at the right voltage level, even with several battery banks.

The Battery Mate is compatible with any type of alternator/battery charger, in both existing and new systems. As the voltage loss between the alternator and battery is negligible, the Battery Mate performs far better than conventional battery isolators. This ensures fast and complete charging of your batteries without having to make additional adjustments to the alternator.

The Battery Mate is most suitable for charging multiple batteries, possibly with various brands of alternators, even if their charge voltage cannot be adjusted. It can charge two or three batteries with a very high yield and without voltage loss.

Models 1602/1603 are suitable for alternators with a maximum charge current of 160 amp, the Battery Mate 2503 is ideal for alternators with a maximum charge current of 250 amp.

Safety guaranteed: The Battery Mate LED display indicates whether the power input is active.

Completely corrosion-proof material with aluminium heat sinks, the electronic components are encased in synthetic materials.

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

Stylish shirt
Size: 14"-14.5" Neck 32"-33" Sleeve, Color: Ash Green
Perfect fit and size, as promoted. The quality and feel (comfort) are nice. The color is a little lighter than what I could see on the screen, but I liked it. The shirt is not too thin or thick.

Great shirt! Great price!
Size: 17"-17.5" Neck 34"-35" Sleeve, Color: Medium Blue
These shirts are listed for sale on Amazon with the title "Unlisted by Kenneth Cole men's Slim Fit." To me these shirts aren't "Slim Fit." I have purchased "Slim Fit" shirts in the past from other manufacturers and they were always too tight on me. I'm 6ft and 185 lbs. To me these shirts are more a standard fit and they fit me perfectly. They are made with a combination of cotton and polyester which means they resist wrinkling. And for about $20 each they are a great deal! Kenneth Cole also sells their "Unlisted by Kenneth Cole men's Regular Fit" on Amazon. These shirts should be called "Big and Tall" or "Full Size" fit. This is the first shirt I ordered, and they were too big on me. They are mostly for chubby or muscular men.
