When you turn the housing on it's side, the lowest battery is loaded with the weight of all cells above. This prevents equal expansion of the batteries. Do not do this, lay it flat as intended.

15kWh of battery for a little over $2000 is absolutely amazing!

I’ll totally do this when I go back in time to an era where people could own homes.

Wow, what a nice channel to find! A guy talking battery and PV stuff without shouting at me all the time, thank you for sharing

Should always connect the positive first in case of accidental short to the chassis

I’ve been waiting for DIY batteries like this. Great video, thanks for sharing.

I was 100% skeptical before watching this video, now I'm 100% subscribed. Awesome content easy enough to follow fast enough to not get bored

I've only used and built DIY server rack batteries, the pre-built EG/SOK/etc are only 100Ah, so to me it was a no-brainer to build 304Ah for $500 more. I currently have 4 of them in Gobel cases, 60kwh, which will run my house in the summer for 24hrs if we had an outage. In 13yrs we've never had an outage longer than 4hrs, but the real goal was to run the entire house during the 4pm - 10pm Summer peak power rate/cost. We are NEM 3.0 here in CA, so there is no upside to backfeeding the grid at $0.03 Kwh while being charged $0.45Kwh.

Great video. You might think that you are too busy then trust a "solar company" to set you up with solar. Well, if you are handy, a gear head or a tech head then please DIY solar set up. The solar companies are a complete rip off with 1000% mark up, mediocre work, poor customer service and once they install good luck if you need to make changes. We spent over $75k on solar setup we could have done better for $20k.

Wow, great unit. Brings back memories of my telecommunications career, I used to work a lot with all the main rectifiers and battery strings small and large 🙂

This is great to see. It’s amazing to see how far costs have come down.

The kapton tape is a very very good idea. I never thought I’d see a DIY battery like this. The potential voltage risks of a short during the build have always freaked me out. Dropping something and having it hit the terminals in just the wrong way. Someday maybe I’ll get past that fear.

Note the healthy dose of competence 😊

FYI - Strictly per the SI standard, the IEEE and others , ' KwH' would be 'Kelvin-week-hours' vs. 'kWh' which is 'kilo-Watt-hours'! There also should be a space between the number and units - .i.e., '100Ah' should be '100 Ah'.

Since a few years that i didn't research about it, one day I will generate my own electricity, is amazing how cheap it becomes and many DIY options. Thanks

I'd love to see how this holds up over time. Great idea!

If it had a JK BMS w/ active balancer and a breaker, I'd buy one! Nice clean look for DIY!

Simple build most of the complex work is done for you. No breaker or fuse in the battery box, consider that a negative. On my DIY system I have multiple battery’ banks, size each breaker so that total breaker current rating is 150% of max load since each battery will only see a small percentage of its current rating.

Thanks for identifying my first project when I retire in a couple of years
