How does everyone secure their batteries? I have three (3) 12V AGM Group 31s located in the forward part of the quarter berth by the nav station and will be adding a 4th shortly. The existing ones are kept in individual plastic battery boxes and secured with straps tied to eyelets screwed into the bottom of this compartment. As far as I can tell, the eyelets are screwed directly into the hull. I am not familiar with the structure at this location, but do I run any risk adding another set of eyelets in the same general location? The screws are very short, but I keep picturing the worst case scenario with the screws piercing the hull! I doubt that is the case given this is a common place for the house batteries to be kept. Any input is appreciated!
