Battery Mate 1603 IG Isolator - 120 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.

Us it Every Day
Size: 6 Ounce (Pack of 2), Style: SPF 50
This is really a great product and easy to use as a spray. I bike ride every day and my ears/face are exposed to the Florida sun. I use it primarily on my face every day. A moment after a quick spray, the product dries, is not sticky, etc. This will become a recurring purchase.

Good protection from the sun.
Size: 6 Ounce (Pack of 2), Style: SPF 50
Does a good job keeping sunburns away. Spray sunscreen never lasts as long as rub-in sunscreen (ie, the bottles run out quicker) so it seems pricier to cover the whole family, but we keep this on hand for days we'll be outside!

SPF ☀️ for Everyday Use 🧴🌸
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1), Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I’ve been using this SPF for almost 2 years now and I still love it! The tint adjusts beautifully to my skin tone and gives such a natural, healthy glow without looking heavy or greasy. It applies so smoothly, feels lightweight, and has a very pleasant smell. Most importantly, it doesn’t break me out at all, which is super important for my sensitive skin. I wear it almost every day and it works perfectly under makeup too. The packaging is also super convenient and easy to use, especially for everyday skincare and travel. Definitely one of the best sunscreens I’ve ever tried — worth every penny!

My favorite Sunscreen
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1), Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I’ve been using La Roche-Posay Anthelios Ultra-Light Fluid Facial Sunscreen SPF 40 for a few years now, and it’s still one of my favorite daily sunscreens. The formula is truly lightweight and absorbs quickly without feeling greasy or heavy on the skin. It layers well under makeup and doesn’t leave a noticeable white cast, which I really appreciate. I also like that it provides reliable sun protection while still feeling comfortable enough for everyday use. Even after trying other sunscreens over the years, I keep coming back to this one because it works so well for my skin. Highly recommend for anyone looking for a lightweight, non-greasy daily sunscreen.
