Data sheet
The voltage-sensing relay (or separator) can charge 2 batteries of different capacities simultaneously from an alternator.
When the engine is running and the voltage of the starter battery reaches the relay's closing threshold, the relay closes, allowing the 2 batteries to be charged at the same time.
When the engine stops and the voltage drops back to 12.8V, the relay reopens automatically, separating the 2 batteries.
No modification of the existing system is necessary.
