This allows the batteries to absorb equally putting less strain on the charging system.
mitiempo was being nice!

This is just plain WRONG. Let me spell that: W R O N G

There is no earthly reason why start batteries need to have an amperage capacity anywhere near the house battery bank.

Especially not with EchoCharge or DuoCharge technology, or even with some of the other methods of "combining" batteries.

One poster on these Boards has 10, count 'em, 10 4-D batteries aboard, total over 2,000AH capacity. I'm just gonna guess that his start battery isn't anywhere near 2,000AH capacity!
