I'm using this to charge six 6v deep-cycle batteries in a Duffy Electric Boat. Each 12v charger circuit charges two of the batteries. Spoke with the tech rep before the purchase who was very helpful and explained that this application was perfectly OK for this charger. After three weeks it's working great - the bank is fully charged 100% of the time.
I just purchased another one to charge the second bank, as both old chargers had failed about the same time. I'm hopeful that the NOCO ones will last many years. So far so good.
Yes, I recommend this product.
