I'm starting out with a 2.6kWh battery pack that is supposed to be delivered today. I somewhat altered my initial plans, I'm going to first engage in the building of a solar powered trailer "generator." So panels, plus battery, charge controller, and inverter, installed on a trailer that can then provide clean power for lighting large areas at night, and/or providing power for tools, etc during the day.
So the battery pack is built from old Leaf cells, I purchased it from http://evbatterycenter.com/ and I intend on using that as my launching point for making my own cells from salvaged Nissan Leaf vehicles. I plan on testing out the components prior to the purchase of the trailer, and I'll post an update once I've got that next stage complete. I anticipate some time in June or July I'll be making progress on the solar power trailer.
