(ET) Batteries swapped and watered

[Christopher Zach <cz bunsen crystel com>]

Swapped in 30 cells from the S10 experience, After a full commissioning 
charge (they took about 900 watts of power which is pretty good) I 
checked water levels and they were low by about 10-15ml per cell. Topped 
them off, added another 5ml to bring them halfway up the V (I prefer 
overwatered to underwatered) I tied in the back pack and checked those 
cells.

A random sampling showed plenty of water, so last fall's watering was 
fine. I'll re-check in the spring and do a full service, but I don't 
think I am low.

Next up, weld in some new supporting metal and fire the deck back up. I 
used my 25+ year old craftsman to bag some leaves on the driveway, but 
man it is so loud.....
