Make sure the batteries are very equal.Use a resister across the ind. battery and measure the voltage drop. Us a good voltage regulator when charging.

You are correct with the logic and double the batteries in parallel will double the watts available. I personally think you would better place your few dollars here at the site below and get a more efficient way of powering a vehicle without the need to recharge ever. Check it out and see what you think.

The wiring would be correct but it would not be the most efficient solution because the batteries are never perfectly matched and in a parallel circuit some of the power from the stronger battery will drain into the weaker one. The best solution is to get bigger batteries.

Your wiring logic is correct. I don’t foresee any problems if you have the space.
