Before building a big PW, I wanted to have a POC (proof of concept) and something I couldfinish in a timely manner.
It's a 3s60pconfig with my B-cells (1700-1900)
Goal is to power my xdsl box and mobile devices. The xDSL modem uses 12wh.
The case is an old ATX modding case I used long time ago when I and LAN partieswhere hot :p

Case is charged with a 100w panel, if it drops to 10.5V I can add a power supply too.
Three buttonsin front. Red, general pwr on/off, orange to activate USB chargers, green to activate green charging.

There's over and undervoltage protection. cutoff @ 10V.

Just another 180 cells I can add to the cell counter......

If you have questions, don't hesitate.

Man, that looks great! A great way to reuse old worn out parts. Referring to the computer case and what not :p

Actually, with a bit more work, you could really make the case a bit more steam punkish, or very futuristic.

Thanks for the flowers Korishan.

The case is re-use, cells from so called death battery packs.
All other electronics components come from aliexpress.
