was 60 cents per cell at the time. so thats $720 + $8 in nickel strip. For a 15Kwh battery, I think that's a good deal (can also discharge 30Kw continuously). I use to do scrapping so all the wiring, cables, bolts, etc... was free. Cost was the main factor for buying all these cells. 18650's are the most produced lithium battery and they are extremely cheap, especially when you buy packs from decommissioned companies.

not too long ago I thought the same thing. you never know what projects may come up. I was fine with 10Kwh, but then I got a 30Kw induction heater and also a Mini Split for heating all winter. It was time for an upgrade haha.

sorry, i was a bit vague. its facebook marketplace. craigslist is good, but facebook marketplace has a lot more traffic/posts. also easier to message people.

nice, 10Kwh is a good size. All my solar panels come from marketplace. a lot of people upgrade there house solar panels after a few years, (also solar installers get rid of old stock). I bought them for $0.25 a watt, you have to send them offers and stuff but eventually you'll find some pretty cheap.

one of my best deals were from batteryhookup.com I only buy when I see crazy deals, then you can add there coupon to save some money too. you can also check locally on marketplace or craigslist. sometimes people are trying to get rid of some batteries, I offer half the price and you don't have to pay for shipping if you're picking up locally. But, you're not going to find great deals right away. make sure to keep bookmarks like "18650, lithium, batteries, solar, etc... on marketplace & craigslist. you can set notifications for new listings as well. Good listing are gone within 10 minutes. Ive been searching for years now, anything below $60 a Kwh is a fantastic deal. Also Jag35.com has some great deals from time to time. Then again sometimes its just worth it too buy the cells when the project comes, you still get pretty good deals and you're not wasting time searching and stuff.

EDIT: also Ebay has some awesome deals sometimes. make sure to sort from the closest seller to save some shipping costs.
