[RE-wrenches] Battery Automatic Watering

[R Ray Walters]

The fill window can also show full, when it is actually dry. You've got to pop those caps, and visually check the old fashioned way.
That's why we're now advocating a "semi, semi auto system" using only one BFS cap with a pressure sprayer to fill each cell. Auto shut off, but then you visually double check the level, before replacing the cap.
