Single Point Battery Watering System
I have now installed the batteries. I wanted to use lead acid batteries to keep the cost down and the fact that they are a little hardier to erratic charging cycles. I have located them out of the engine room below the companionway steps. This means that they are a little harder to maintain. So I searched for a way to do this easier, enter the battery Watering System. I think every boat that has lead acid batteries should have this. Fill all your batteries from one source. They all fill to the proper level, and they fireproof the battery.
