Here is what I would like to do.. I have an old Lowrance flasher unit that I would like to install on my little 10 ft Jonboat and I am working on how best to power it. Leaning toward using a motorcycle battery to power it and maybe running lights but I am wondering how well it may stand up to repeated discharges. Perhaps I would be better off going with a battery from an electric scooter? Weight and size are considerations. Thoughts? Suggestions?
