re: On-board battery charger installation options

I have two Minn Kota onboard chargers. One is under my console next to my trolling motor batteries and the other is mounted on the bottom side of a hatch lid that provides access under my deck, away from my starting batteries. I prefer that mounting location. When I was running lead acid batteries for my trolling motor, the vapors produced by the batteries when charging were corrosive and ate the finish off of my charger. I did switch to AGM batteries and that solved that problem, but it was an expensive solution. I am still using LA batteries for starting batteries, but because they are away from the charger, I don't get any corrosion. When I start charging, I just throw the hatch lid back and that charger gets plenty of ventilation.
