Just a comment when connecting batteries in parallel, ensure all batteries are equal capacities and types, as identical as possible to ensure uniform behaviour. With a parallel battery bank, [2 or more] one fuse is usually adequate for protecting the wiring against load over current between the parallel-connected batteries and the load.
Batteries have been known to internally short-circuit, due to electrode separator failure, causing a problem not unlike that where batteries of unequal voltage are connected in parallel: the good batteries will overpower the failed (lower voltage) battery, causing relatively large currents within the batteries' connecting wires and heat. To guard against this eventuality, you should protect each and every battery against over current with individual battery fuses. It may even be wise to have a quick disconnect system easily accessible. If the batteries are stored under seats etc, quick access in an emergency may not be possible. I have seen large batteries explode, spraying acid is not good…
Be safe.
