Upgraded my charger to a PS4 DeltaVolt this spring and had to some reinforcing on the plastic panel over the bilge where it mounts. I added a 3/16" aluminum plate with 1/4-20 SS rivnuts to hold this 33 lb beast and after a few months I started asking myself why am I carrying this thing around with me up/down the HWY and then hauling it around while I'm fishing? Didn't make sense to do that if I'm not using it. Like most folks, except the traveling tournament fisherman, I use the rig and tow it home and charge it there. These pigs are heavy enough without hauling extra weight around.
I yanked it out and mounted it on the wall with a removable bracket/20' long service cable so when I do travel I can take it along. After clearing my materials selection with the guys at Charging Systems this is the end result. Less weight in the boat. More room in the service well and less cluttered. Less abuse to the charger. No voltage drop in the 20' cable or waterproof plug. *Note: You will need to Dremel out the entrance slightly for the cable to fit inside each plug.
Pictures explain the rest.
