I just got a Minnkota 210 onboard charger and am trying to determine the best way to mount it. The instructions said to not mount it directly to the aluminum to prevent electrolysis from occurring. My first though is to get a piece of HDPE board and mount that to the boat and then the charger to the HDPE. Is this the best route or does anybody else have a better idea?
Thats how I did mine.
Did mine that way too. Works like a charm.
I mounted mine using two blocks of wood. One under each set of mounting holes. The blocks run perpendicular to the charger. They also provide the added benifet of giving me an airspace under the charger to help dissippate any heat build up.
Get a cheap plastic cutting board from Wal-mart. Anything to isolate the two dissimilar metals.
This is a problem I didn't even think about--but avoided (by sheer luck.) I chose the Dual Pro onboard charger & its case is plastic.
i think i will pay someone to do mines i have 2 batteries and want to add a 3rd i have 1 in thhe back and other in the front of boat.
OK, the things are electronic and generate heat. Heat kills electronics. Gotta soak out the heat or give it plenty of air space. If you attach it to the aluminum, you could get bi-metal reaction. I made 4 nylon spacers and stood mine off 1" to give it plenty of air underneath. No problems. If you sandwich a piece of plastic between charger and aluminum ok, but apply heat sink compound or thermal jelly to mating surfaces.
I used a piece of plywood for mine.
If it mounts with bolts, just use some rubber washers between the back of the charger and the boat. I've got a 4 bank charger mounted in a covered hatch this way. I just open the hatch when the charger is plugged in for ventilation.
I would think anything would has long as it isolates the 2 metal surfaces
I went and got some 1/4" x 1.5" stainless sheet metal screws and some nylon washers to mount it with. I'm going to put two or three washers between the carpet and the bottom of the charger and one between the screw head and the charger. That should keep it isolated from the aluminum pretty well and give it a little breathing room underneath the charger as well. The bilge has a big hatch above it so I will just make sure to keep it open when I charge my batteries. Thanks for tips!
