Relays-&-Power-Distribution
Mastervolt Charge Mate Pro - AGM/Gel
A secondary battery on board requires a dedicated charging solution. The Mastervolt Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This makes it possible to distribute the charger or alternator current effectively between two battery banks. 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. The Charge Mate Pro series consist of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications.
- Electronic charge coupling with very low voltage drop.
- High system reliability by prioritized charging of the main battery.
- Prevents power dips of the onboard electrical network.
- Suitable for all kinds of chargers and alternators.
- IP65 electronics in a corrosion resistant casing with aluminum heat sinks.
- Fast and easy installation.

Mastervolt Charge Mate Pro - Lithium-ion, LFP, LiFePO4
A secondary battery on board requires a dedicated charging solution. The Mastervolt Charge Mate Pro Charging Lithium 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. The Charge Mate Pro series consist 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 fulfil even higher continuous power demands of your equipment on board.
