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.

Good sunscreen
Style: SPF 50
Super good coverage and it lasts a long time in the sun and even through water activities. The only negative is the white cast. Not as bad as others but just be aware it doesn’t fully rub in.

Great sunscreen & works for kids - even used in resorts!
Style: SPF 50
Terrific! I don’t feel it is as good as chemical ones but my favorite non-chemical one. Used on a long vacation and it did the job! Also didn’t cause pimples like other thick versions of this.

Protection
Style: SPF 50
I love this product, especially my husband because it’s all-natural. It contains minerals that leave a slight white residue on the face. While it would be nice to have a clearer texture, it does a beautiful job of protecting you from the sun.

Oily skin win
Size: 1.7 Fl Oz (Pack of 1)
As someone that refuses to spend $40 on a 1 oz bottle of facial sunscreen, I decided to give this one a try. For some background, I have very oily olive skin. I've been using tretinoin for 6 years. Currently, I've been using the .14% of tret for the last year or so. With that said, it's interesting balancing the dryness of tretinoin with my oily skin. This sunscreen is fantastic. It doesn't make me more oily. The price point is good. No breakouts. Doesn't feel heavy or greasy.

Non-irritating, daily sunscreen for sensitive skin
Size: 1.7 Fl Oz (Pack of 1)
Sunscreen does not leave a white cast on the face, which is great! I have sensitive skin, but this sunscreen doesn't cause irritation or dry out my face. Perfect for every day use. Definitely will buy again.
