Thank you Miller for your prompt reply. The reason I would like to have the battery outside is because i can essentially take the battery out , charge it , and fix it back in with ease.
Also the pro angler 17 has specifically designed the battery platform outside the hull, and I assume the reason is because of Skid and Rudder on the back removed the ability to have storage compartment.
The most important reason though is I like minimal rigging when it comes to what lays on the deck of the hull, so the front hatch + the 3 hatches on the deck are all used and full already with accessories and tools keeping my hull clean and tidy

I will eagerly await your reply on the solution , thanks again
