Product Description

Charge Mate Pro Lithium 90

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 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 in 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.

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.

''Awesome discounts on fishing reels and GPSs. Plus they have next day shipping. The convenience of online shopping is awesome, especially since it's getting harder to get around in store.
They made sure I got the electronics I needed and all the hardware for the install. They even do repair and installs, so I ended up hiring them for the work I needed done on my Mercury. Awesome experience.''

JAMES

"Great experience! I Was looking to purchase a head gaskets for my Johnson 150 hp outboard motor. Mike & Ashley researched parts I needed and come to find out they turned me on to my outboard engine used O-Rings to reassemble my head covers and provided me with parts and torque specs! Thanks! 100% positive feedback and Recommend this Family Business if you need Marine Supplies."

SCOTT

Family owned and operated, which is a huge plus for me! I was browsing the website looking at Garmin gps units, their prices are great and competitive! I reached out to them to ask where I might find a hard to find lower unit part I was needing. They had it in stock! If they don’t have something in stock, they will get it asap! 100% recommend and I will buy from them again in the future!
