This is the battery mount we made for the carbon fibre Braille battery.
A carbon fibre plate will bolt to the rear of the bulkhead to support the back of the battery & an alluminium angle bracket to support the base of the battery.
Longer midshaft bearing housing bolts extend through the bulkhead to mount the alloy bracket.
Rubber was bonded to both brackets to protect the battery.
Rubber straps stretch over the top & around the side to hold the battery securely in place.
Very short positive & negative leads can be used from the starter motor & e-box to the battery.
The battery sits just above the prop shaft & weighs next to nothing, so not sitting directly on the base of the hull was not an issue.
