May I ask why 18650? 21700 have better energy density and theyre easier to get these days. The price has also come down a lot.

Because I have a metric shitload of them available. Indeed if i was going to order fresh cells 21700 is better especially for a home battery system.

Way better to use your old junk. I like that youre make your own home battery, ive considered it. I have solar installed and would love to not consume grid power at night. I’m thinking of installing a bank of lead acid batteries under my ground mount solar that would dump power into my home at night.
