Auxilary Battery Always Ready This is an excellent product at a competitive price. I plan to put one in every car that I own. Great features in a nice package. A well engineered product.

Solid Charger, and consistent 40A Output As long as the input is sufficient, you will get a solid 40A output. I still plan to buy an alternator protector from Sterling. Nothing to do with the Renogy, but if the battery BMS shuts down for some reason (which can happen), it will protect your alternator from the spike it receives up the line. Again, nothing to do with this particular DC to DC (I recommend this on all DC to DC applications), it’s just an added tip. As far as the charger, seems to be a good little unit.
