SR to ER battery swap DIY project

[Ynnhojnorood]

At this point we are talking about an F150 that weighs as much as an F350. The Lightning is already a ton over an ICE F150. Tom's video about local street weight limits brings EVs into a new light. Those Chevy, GMC and Hummer vehicles are over 4 tons. I think the F150 nailed it by keeping it close to 3 tons with a bit less range. All that extra weight for an extra few miles? Did you see the Hummer? It's like the old GM Hummers as far as inefficiency.

I’m now in a Sierra EV (Max) and get the same mi/kwh as I did in the lightning. I can’t imagine the Hummer is that much worse.

Rolled the dice on this ER battery on eBay. Anyone else out there do this yet? Wish me luck boys and girls.

I rebuilt the battery on my 2006 Prius, but a couple others at the time had blazed down that trail before me.

My hat's off to you, Sir! We are all rooting for you.

Sorry, I replied before seeing your reply!
But yeah, those DIY battery storage systems you're lucky to get above 5kwh out of any wall mount battery. Imagine having 10-20 times that?!?

You could but it'd be alot of reconfiguring of the cells in the SR pack to get it to your existing solar battery bank voltages along with a custom BMS. At that point, you're just harvesting cells. It would however be nice if I could figure out how to repurpose the onboard level 2 charger and 2 phase inverter... the options would open up quite a bit...

There are HV battery inverters now, as I have used a Nissan Leaf battery for home backup. The Lightning battery would be great!
