i have a new boat and the motor crank battery is just flapping around in a storage compartment
under the rear casting deck. is this ok? i would have thought that it would need to be clamped or
at least in a battery box. if it is ok can i put 2 150amp battery's in a box under the front casting deck?
if it is all wrong how will i fix it properly?

the cranking battery


where i would like to put the bow mount battery's
