Menbaa Split Charge Relay 70 A, 12 V, D+ Controlled, with Diode Protection - Separates Starter and Leisure Battery
- Menbaa split charge relay 70 A, 12 V, D+ controlled, diode protection.
The Menbaa split charge relay links the starter battery with the leisure battery of a motorhome or caravan while the engine runs and separates the two batteries once it stops. This way consumers in the living area cannot drain the starter battery. Maximum switching current is 70 A.
How it works
The relay is controlled by the D+ signal from the alternator or a D+ simulator. Alternator diode protection is already integrated. It is a simple, proven solution for vehicles with a conventional alternator.
- 12 V, max. 70 A
- D+ control
- integrated diode protection
- compact, 35 g
Important for Euro 5 and Euro 6 vehicles
Many Euro 5 and almost all Euro 6 vehicles have a smart alternator. In such vehicles a split charge relay and D+ simulator work only partly or not at all. To charge the leisure battery properly, a charging booster (DC-DC charger) is needed.
Safe installation
Work on batteries and heavy cables requires care: disconnect the negative terminal before fitting, tighten terminals to the right torque and protect every circuit with a fuse matched to the cable cross-section. If in doubt, have an auto electrician do the installation.

Questions and answers
Will it work in my Euro 6 vehicle?
Usually not fully, because these vehicles have a smart alternator. A charging booster is then the right choice.
