Hello,
I have a boat with 1 Engine, 1 Starter battery and 1 auxiliary battery.
I would like to use the Cyrix-ct-230 to automatically charge the aux battery once the starter battery has been charged. With the added benefit of having a start assist switch from the aux battery in case the starter battery has been drained.
My question: How would the Cyrix react if I use start assist to combine a full aux battery with a completely drained (or dead) starter battery? Would the Cyrix refuse to connect? I'm concerned that the drained/dead starter battery would drain the aux battery.
