Can I get recommendations on where to buy affordable 18650's to build a powerwall?
I am planning on needing 200 or so for my first build.

Are there better LiFePo batteries for the price to build home Powerwalls than the 18650's?

Thanks!

Second hand 18650s seem more scarce this year - maybe due to a lot more interest in LifePo4?

Here's my top 3 sources....
--- good price + honest descriptions ----
1) BatteryHookup - https://batteryhookup.com/ - Have purchased north of 5000 cells over the last 3 years. Mostly 'modem' cells. All as advertised!
2) Battery Clearing House - https://www.batteryclearinghouse.com/collections/all - Purchased about 2500 or so RING pack cells last year. All as advertised!
--- pricier but honest descriptions ----
3) Power2Spare - https://www.facebook.com/Power2Spare18650/ - Purchased about 1000 both pre-tested and raw NCR18650As over the last 2 years. All as advertised!

18650s cells can be cheaper per kwh than LifePo4..... BUT more work! A case can be made to pay more for LifePo4 and get more cycles and work less.

The size of the battery matters here - at 200 18650 cells it's so small the price difference isn't much. In my case, I'm nearing 12,000 cells so it's significant!

But maybe you just want to try your hand at 18650 cells or something like that so a small price difference may not be the main issue?.
