    Kind of fell into a rat-hole regarding lithium batteries for solar storage. Feels like it might fit here. Anybody followed this guy in CA called Jehu Garcia? He has a cool 60's VW microbus converted to EV and has a ton of cool videos on youtube of hacking lithium batteries, building out tesla like packs, etc. He sells DIY kits and resells used batteries as well. Recently he got ahold of a cache of used scooter packs. 40 Panasonic cells. 36V nominal pack. I've been following some of the FB and forum threads about "waking" the BMS on these packs up. Seems like they have started to figure out how to use these packs out of the box. People are talking about building powerwalls out of them. Garcia posted videos of getting a ~4kW config up and running on a bench. .. He's selling the packs for about $50/ea. That seems insane. Little over $100/kWh of battery. That's right about on par with deep cycle wet-cell batteries.

    I would be very tempted to tinker with these if I were building out another camper right now. Hell, I'm tempted to buy a couple packs to play with for shitsngiggles. (Because I need another project right now!)

    This threw me down a rat-hole watching videos and learning about DIY powerwall setups. We just installed solar on our roof at home and I'd frickin' love to be able to have a battery backup.. sell off that boat-anchor gas genny that takes up space in the garage.

    yes, been watching vids with Jehu involved over the past few months, mostly because i'm a vintage VW fruit (and EV West fan for a few years now) but ... yes also, because a recent smart home project of mine was to create a UI / experience for home energy management. super cool stuff + i / we dream of going off grid one day. one of my clients supplies complete microgrid configurations with critical load management ($$$!), and another is just getting into it on a larger scale (multi-family housing).

    batteries are so gross to me but whoever figures it out (true recycle) is going to win a big prize ... oh, hi, Tim Apple.

    Overdue status update. Ain't perfect, but good enough. No deep explanations, but ask away.

    Cabinets, power columns, paint, drawer/cabinet faces, garage, some trim. The end is in sight. Only need to figure out the section between the bench and bed.

    I've been eyeing the Winnebago Revel. It's a $150K turnkey rig at Flagg RV near me. The 2021 is full lithium off the grid setup. Hard pressed not to sell my toyhauler and go that route for more stealthy travel for MTB, surfing and bumper hauling my 790. I don't see myself as handy enough to build something like you are doing.

    I'd love a Revel. They're kind of the perfect sprinter. Not all that stealthy, but very sexy.

    Compared to my Toyhauler it's stealthy. Also the 2021 paint is Mass State Police blue. Maybe have a few big STAY POLITE decals on it.

    I did not, buy my fuel mileage has definitely dropped! I really wanted the 7 speed transmission which was only available in a 4 cyl diesel. It still moves fine, but it isn't getting any faster. The v6 diesel would have been nice.
