Charge Mate Pro 90

Current limited electronic charge relay with high efficiency and reverse current protection

A secondary battery onboard requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.

The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the ChargeMaster Pro.

A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.

The Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications. The Charge Mate Pro 90 ensures a higher charge current for example when charging Lithium-Ion batteries. It is also perfectly suitable for large automotive alternators up to 180 A and can be used in parallel operation with a 225 Amp alternator to fulfill even higher continuous power demands of your equipment on board.

Charge Mate Pro: for controlled charging from a single source.

This product is da' BALM! (a softening balm that's the best moisturizer for all skin types!)
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
So many of these are all over social media and I wasn't sure to order a whipped version, or just a balm, so I went with the balm and I'm totally satisfied. No breakouts to my sensitive, mature dry skin, and the scent is light citrus and non-lingering. I suggest to lightly swirl finger tips inside the container in a circular motion and scoop a tiny amount then rub both fingertips together to warm the product as this is key to make it glide smoothly onto your skin, otherwise, you are having to re-dip into the product and use more than you will need. I use it AM/PM right after my facial serums, and follow with SPF moisturizer. I'm not a fan of foundation or powder to avoid the caked on look, but use a little creme blush when heading to work, and will dab a little concealer where needed too. I've been using my Ancestral Haven Beef Tallow/Honey Balm a couple of weeks now and my pores seem smaller than when using any of my previous French pricey skin products! I use this on my face and lightly under eyes, neck, decollete and the heels/sides of my feet every morning. Any remaining product I apply to top my hands. It absorbs quickly without being greasy. If you experience an oily result, then lighten your next application as the product is light if you don't warm it up with your fingertips. I highly recommend and can't wait to tell my dermatologist about it too! Oh and my 86 years young mom uses this daily and loves it too! (Christmas gifts coming her way so she doesn't deplete my supply - lol).

Tried 100’s of product and this is all my son lets me use on him willingly!
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
The ONLY product I can put on my child’s eczema and allergy problematic skin and not irritate his skin. My son has TERRIBLE SKIN that is EXTREMELY sensitive and to top that off, he also picks at his scabs. This is the only product I’ve ever been able to use on him and use up the entire product because he doesn’t breakout in a rash, it doesn’t sting his skin in even the worst of areas that are freshly picked scabs, and that’s a huge deal for us! It is extremely moisturizing and although slightly greasy, it’s a much better feeling on the skin then what you get from a Aquaphor or petroleum jelly. That and my son absolutely cannot stand the texture of Aquaphor and petroleum jelly, but with the tallow, he doesn’t hardly say a word as long as I don’t put it on too thick. This can be layered for extra protection in problem areas, or worked into the skin and absorbs quite nicely and feels fantastic! It has a very mild scent that I truly love, but the scent doesn’t really travel outside the jar so you know it’s very minimal. After the hundreds of products that I’ve tried and the thousands of dollars wasted over the years, I will continue to purchase this as my holy grail for my son’s extremely sensitive skin condition. Thank you so much!!!! And I will upload pictures of before and after so be sure to see how well it’s healed his skin within a week of use!

Amazing smell, awesome price, and nothing synthetic
Scent: Honey & Sweet Orange, Size: 5 Ounce (Pack of 1)
This is a new staple in my skincare regimen! With no synthetic perfumes dyes, or preservatives, it smells wonderful, melts into my skin without leaving a greasy film. I use it morning and evening on my face and body, and my skin never feels dry. It leaves my skin soft and moisturized and I have this on subscription. The price is great, at about $20 for 5 Oz of nonwhipped, but soft, balm.
