Re: Building a New battery system, need ALOT of help
How large a bank do you want in AH?
4 golf carts in series/parallel makes a good bank if you need one that large. I would prefer it over 12 volt batteries with the same AH total.
Deep cycle batteries have no problem charging with a lot of current. They will accept about 25% of capacity in bulk stage. And a charger cannot be too large - the batteries will accept what they need. If you are cruising and stopping at a dock overnight to plug in the larger the charger the faster to full charge. If you are returning to your home dock after a weekend and will not use the boat until the next week it is less of an issue.
The Iota DLS-55 is a good choice. Make sure to get the IQ-4 option to make it a 3 stage charger - either built-in or separate.
