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.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.
