Battery Mate 2503 IG Isolator - 200 Amp, 3 Bank

The Battery Mate is the ultimate solution for charging several batteries simultaneously and 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.

While battery isolators are conventional diode splitters, the Battery Mate's technology is electronic and includes mosfets (transistors). Its components compensate for variations in voltage and ensure that charging continues at the right voltage level, even with several battery banks. The input side on the Battery Mate is connected to the alternator and/or battery charger, while two batteries are connected to the output side. The Battery Mate is easy to install on a DIN rail (industry standard).The Mastervolt Battery Mate can be used in any application even if the standard alternator need external excitation or voltage sensing. In this case the additional IG contact can be connected.

WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm. For more information go to P65Warnings.ca.gov.

As expected
Color: Gray/Gray/Digital
Just an old school digital timex. Tried and true. Has both 12hr and 24hr function on the time setting. Has a standard stop watch and timer. The battery is great, just as it always is on a timex. Good water resistance and very easy to use. Overall very good watch for the price!

Can’t read numbers

Numbers are too small to tread on a 44mm watch

I absolutely love these watches! They are built like a tank. They can take a lot of abuse and still keep great time. I originally was going to buy just one to replace my old watch. Ended up buying several of them. Great gifts. The watches are beautiful and elegant, and I feel like a thief when I buy them because the price is so low I think its a typo. I have gotten several compliments on them when I wear them. I have busted up concrete and cleared heavy terrain ,cleaning areas out, wipe then off and they look Like I just took them out of the box. The only thing, and it's not a big deal to me.But the glow in the dark arms don't last long. They even give you the tool to adjust the wristband. Who does that🤣 The Quality of these watches are phenomenal BUY ONE! You won't be disappointed.

Very handsome well-made watch comfortable to wear.
Color: 5885 Siver Stainless Steel/Blue Dial
Very handsome watch. At first glance, it resembles a Rolex. In two days I’ve gotten multiple compliments. Several have asked if it was a Rolex. That’s hardly what I was going for, in fact I had to look up Rolex watches to see what was being referenced. The watch fits very comfortably.
