Now that I’ve got four nice new Costco batteries, I have to get them into the boat. The original setup on the Hunter 340 was to have all the batteries in the starboard lazarette, sitting on top of the holding tanks with a few nylon straps. These batteries are 63 lbs each, four would be 240 pounds of battery on one side.
I’m told the boot stripe is painted higher on the hull to compensate for all the weight on that side of the boat. My plan is to put two in each lazarette. This works for several reasons:
- weight balanced between port and starboard
- batteries can sit closer to the centreline
- being 6volt in series it makes sense to keep them in pairs.
The starter battery an AGM yellow-top Optima and will go down below behind the aft berth bulkhead. It will sit low low and on the center-line, ignored for the season.
The boxes will have nylon webbing over top to secure the batteries in the boxes and the boxes will have stainless carrage bolts through the lazarette floor to keep them still.
I’ve decided to paint the boxes with epoxy coloured black with 423 Graphite Powder, as I have it left over from the rudder slop repair.
“423 Graphite or powdered tempera can be used up to 10% by weight.” as per West System, I’ll go with 5%.
