Mastervolt Charge Mate Pro 40
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 40 provides additional functionality by limiting the charge current to the second battery to 40 A. The main battery is therefore charged with priority. The return current is automatically blocked, which reduces power dips of the onboard network. An emergency start function is possible by connecting an optional bypass switch.
