Hi all,
I'm a layman so be gentle. Basically I live on a boat and I'm off grid. I have a bank off batteries that I use to power my boat. I managed to pick up 6 3000f maxwell capacitors used from eBay. I want to use them in parallel with my 12v battery bank so that when any sudden high current draw motors turn on the capacitors take the strain. I've been told that this should extend the life of my expensive batteries and also extend the ah of the batteries as the relationship between the average current draw and Ah is reversely proportional. The problem I am having is that my solar charger and alternator will not charge the battery or cap bank when it is connected. I'm assuming the the very low resistance of the caps is confusing the changing systems. I've also been told that in hybrid busses that the caps would be isolated from the batteries via a dc to dc Buck converter. This would be very expensive and to be honest beyond my ability to make. My alternator is 175 amps. I was wondering if I could use a high powered resistor between the charging systems and the caps to match the resistance of the caps to that of the batteries so that he charging systems would work? I could then use Buck convertors between the caps and loads which I could get from eBay.
