Hello, I have a very modest 56AH AGM battery bank in my Jeep. I am grounding to my chassis. I can't seem to find the 12/12-18A DCDC in the (non-isolated) version. Assuming it doesn't exists, will the 12/12-30A overwhelm my 2 paralleled 28AH AGM batteries? I've attached the spec sheet for my batteries for reference sake.
Where did you read that there is a 12v/12v 18 amp non-isolated?
Why can't you use 12v/12v 18 amp isolated?
No, the 12v/12vv 30amp will not overwhelm your battery bank.
If the batteries are going to be deeply discharged, there's a good chance of overheating the batteries.
In round numbers, you have a 60 amp hour battery. Meaning a full charge in 2 hours. The data sheet doesn't give a charge rate. Pumping 30A into this for short periods will be ok. Pumping 30A for long periods won't. Aim for a charge in 5 hours or longer. Preferably more. The faster you charge the shorter the battery life.
In any case stick to the lowest charging voltage. There isn't a float voltage specified. Normal for lead acid/AGM is around 13.7V.
