Sure ... Agreed ... but only if you can charge it with a 14 hp engine in a couple of hours.

Re: Electrical System Update

Just because you have more battery capacity doesn't mean that you use more AH. It is not any tougher to put 100 AH into a 900 AH bank than a bank half the size. The larger the battery bank the higher the SOC they go down to with a given load. Because of this they will last longer. Due to Puekert there are gains in bank size beyond the 20 hour rating as well with a given load.

A 100 AH battery with a 5 amp load is 100 AH. A 200 AH bank with the same load is somewhat more than 200 AH.
