So, I&#;m seriously considering building a DIY battery. Watched Will build a few on YouTube and it looks like fun, and a good learning experience. A while back Will built a 12 volt, 200 amp hour battery with Fortune cells and a Overkill BMS. The 8 cells cost about $960 ($120 each), and the BMS another $142, which totals $. The Overkill BMS also has Bluetooth and a great app. Then I saw him review an SOK 12 volt, 206 amp hour battery - which he highly recommended - at a cost of $. In that review video he states &#;you can make your own battery for much cheaper&#;. I&#;ve also seen many other YouTube videos where this is stated as well. So, I&#;m a little confused, and am probably missing something very obvious. Am I comparing apples to apples? Can someone please shed some light on this subject. Thanks!!

I can share what I'm doing. I just built one of these a week ago (although with grade B cells). The finished results are quite nice, and prompted me to order 3 more of the battery kits.
First, grade A cells:

Yes, I'm sure you can order grade B cells for much cheaper. I'm going with grade A myself.
Battery box kits (they actually sale everything you need):

JBD 150 amp BMS (you don't actually want to run your cells above 0.5C or 140 amps).
The ones with grade B cells I'm giving to my grandson and sister along with an
For myself, I'll probably use grade A cells and put a few in series for a 24v all in one.
A 280AH battery at 12v with a quality BMS is nothing to sneeze at, especially since you can run those BMS in series. Add matched grade A cells, and I suspect that even in series they will stay balanced quite nicely.
I have no financial interest in anything, I'm just very pleased with the quality of everything I've linked here, and would highly recommend them.
Edit to add, I'm going to check and see if the EVE 304AH cells will fit, or if they have plans for a plate to make them fit.

We&#;ll be honest here. There are some reasons to stick to lead acid batteries. For example&#;
SUNJ ENERGY contains other products and information you need, so please check it out.
You love shopping. For batteries. Every few months or years. (Less if you don&#;t maintain them).
The thought of your conventional battery dying on you suddenly in the middle of the desert thrills you.
You enjoy cleaning things, especially leaking acid and corrosion.
Ok, maybe we got a bit carried away here. But the truth still stands: lithium is the future, and lead acid is the past. The distant past - invented in . You probably don&#;t own a closet full of s clothes (or anything else, for that matter) so why should your batteries be any different?
