If this is a successful test(over a week and with no permanent damage to the battery). I hope to scale up to larger motorcycle batteries (possibly 3 of them for a total of 12v) and connect them to a thyroid transformer, or inverter to power larger loads. Or I may go another route and forgo the lead all together. The main reasons why I used lead batteries:

1.) Availability

2.)Recycle-ability(lots get thrown away everyday)

3.)Mature tech(less guessing and prototyping)

4.)Plate distance & "surface area:mass ratio" (greater power output and energy density than youtube style pipe crystal cells).
