I just bought this: https://www.amazon.com/gp/product/B003JSJS5I
20A, 2 bank charger.
Thing is, reading reviews, it is saying the 5 year warranty is null and void if I modify the cords in any way.
So normally I would have cut the end off the AC plug and wired it into the shore power the same way my current charger is. But if I do that, bye bye 5 year warranty. So I need to wire an outlet or an extension cord.
I'm a bit of an amateur electrician. Done a few projects with careful research like installing my galvanic isolator, wired/soldered connections for interior LED strips, made some connections here and there and replaced fuses, etc.
Just want to check in with y'all.... can I snip an extension cord, wire it the way I would my charger, then plug the charger into the female port on the extension cord? I know, I know, it is an exposure to salt, moisture that I would prefer to avoid so I'm going to solder/dielectric grease/heat shrink the cut connection and wrap the extension plugs with electrical tape. but will this work? any better way to do it?
