Charge Mate Pro Lithium 40

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

A secondary battery on board requires a dedicated charging solution. The Charge Mate Pro charging relay 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 Charge Master 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. 

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

Applications:

Leisure and professional marine and mobile applications. An effective solution for high power demand on board and/or the need for prioritized or current limited charging.

Be aware! Once they are on, do not walk! 😂
Flavor Name: XL silicone socks 2 pairs
I absolutely love these things. But the first time I put them on in the living room. The walk to my bedroom was VERY interesting 😂😂😂 I now know I need to put them on and hang out for a bit, or simply go to bed. They do exactly what I need them to do. Feet feel great afterwards! With the right lotion, only need to use one every couple of weeks.

Transformed my feet
Flavor Name: XL silicone socks 2 pairs
After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product
