I fitted one of these to charge a 170Ah Renogy lithium battery in my Sprinter van. I charge from the starter battery/alternator when the car is running and from the solar panels when the car is off. This charger automatically selects the power source to charge the battery. I've found that it takes a minute or two for the charger to turn off the starter battery/alternator when the van is off, but that shouldn't be a problem. Very happy with it so far!
