Hello fellow diy powerwalls members , i recently joined this website, i am a automotive & light,medium & heavy duty truck technician , as well as a class a,b & c driviing motorhome repair technician and i fix fifth wheel and bumper pull travel trailers, anyways i am beginning the planning stages for building a 4kw powerwall in my utility trailer with solar to recharge the 18650 cells, i don't want to carry around a generator and i'd prefer to use natural resources. The particular 18650 battery chemistry i am interested in using is Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC)

I have been looking through the battery cell database, but i am new to power banks so if anyone can give me some beginner advice towards finding the battery cells i want i'd appreciate it.

Welcome!

Best way to get cells is to buy them new from like nkon or even scout for almost new on Ebay. (Watch out because 99% is fake)
Then after is scouting for instance after laptop packs.
