For those of you that know or own these systems, I've been watching quite a few videos from various people about dual battery setups. One main video posted by Andrew St Pierre white got me heavily confused. Now, reading the "how it works" from the genesis website, I clearly understand, and that type of system was all fine and dandy when cars didn't use "smart" alternators that didn't drop the rate of output. Now, we have a system that shuts down the alternator output when it senses the battery (main) is at operating voltage, which creates an issue. Basically, once the cranking battery is charged (and say you just left camp where you heavily drained your aux battery), the rate of charge is significantly reduced, and when the isolator links the 2 batteries together, the aux battery is getting a low and slow rate because the alternator thinks the battery is full or near full, thus feeding it a slower charge. The only solution it seems for modern smart alternators is to have the system have a smart DC-DC converter like one offered by redarc instead of the isolator. How are you guys handling this situation (and have to actually tested that your aux is getting to 100%?
