I wanted to create a quick thread of what I've done over the past year. As a novice, this has been a great experience and I've learned a lot in the process. I'm close to 14 packs of 80 cell 2000 MaH presently. I'll post pics of the the whole process from the beginning and share tips that I've left learned along the way. A shout out to Mike is definitely in order. Thanks for answering nonsense questions and letting me follow in your direction.
 
Lol I had to update it! I accidentally messed it up. Updates to come and pictures to share

So it began...I bought an IMAX charger at first and used an old flat copper busbar design on my batteries. Those weremy first two mistakes...

I thenought two Opus charger/dischargers and a efest 6 cell charger to move my process along. I switched the the 6AWG busbar design and haven't looked back. I was also using copper bars on my busbars with a thick copper bar between the busbars to connect my packs. I've also moved on from there to copper terminals and bending the busbars.

I use rosin flux and a 30awg wire as fuse which has been tested on this forum and works great (in theory) for our packs. I haven't had a run into problems with these other than buying the wrong things and learning the hard way at first. I also have been using a 30w soldering iron.

I started connecting my packs (not pretty) and figuring out the best configuration. I then ran into the copper terminals and again, I've since moved on with the terminals instead of the old way. I had over 12v with the batteries connected so I bought a 12v inverter and created a really cheesy video. Will post next.


This was my first load test and it was only 60w for 2 hours to test out my batteries to make sure it would work. Everything ran great and I know I'm a nerd, no need to comment of how much of a nerd I am haha

This was my first picture with new copper terminals and I love it. Less work and they are tightly fit for connection

10 packs finished so it was time to hook up my 7 packs to the charge controller to test it out. It all worked! Ordered a DC connect to hook it up to a solar panel (with a rooftop disconnect) and to start charging my packs.
 
Looking very nice.
 
Awesome work!
 
Good work m8!
