Mastervolt Charge Mate 1204

Onboard systems usually consist of two or more batteries that function independently when powering the 12, 24 or 48V consumers. These batteries require independent charging with reliable battery isolators or battery combiners.

Mastervolt offers several intelligent solutions:

• Battery isolators that divide your charge current with a minimum energy loss.
• The Charge Mate for connecting and/or disconnecting two batteries.
• Battery Watch for monitoring the condition of your batteries (also usable as main switch).

A secondary battery is becoming increasingly common. As a second battery can prevent the main battery from depleting and being unable to start, this seems like a safe and reliable solution. The second battery, however, also has to be charged regularly.

The Charge Mate series connects both batteries during charging and keeps them isolated when discharging. The Charge Mate 1202 and 2502 are especially practical for small systems, the Charge Mate Pro provides additional functionality by limiting the charge current to the second battery to 40A or 90A. The main battery is therefore charged with priority. The return current is automatically blocked and power dips of the onboard network are reduced. An emergency start function is possible by connecting an optional bypass switch.
