If the budget allows, I agree.

If you use a regular marine deep cycle battery, you will have to take greater care to orient the battery with the proper end up. If that is a problem, upgrade to gel cell.

Do not use a car battery - they are engineered for "cold cranking amps", which means that they can put out a massive current for a short period, but cells tend to short out after a number "deep cycles" (more than 50% discharge), which is how it appears you will use them. Marine batteries are designed to be charged on land and discharged while on the water.
