So.. that update I promised is here!
I finished capacity testing the new batteries, they _are_ amazing. Well, a bit better than my dark green ones. I'm not listing the capacities here, take a look at the pic below. Half of em 1700mAh, the other 1900mAh. IR seemed to correct itself after refreshed, all register 120mOhm.
After I finished soldering the parallel groups. Not using the purple cells.
Please don't mind my soldering skills - these batteries are NOT meant to be soldered. Had to first sand the poles, flux, tin, then solder the salvaged nickel strips (also fluxed). It gets warm, but nothing dangerous.
Then on to series them.. Again, don't judge me. I put the weakest, light green cells at the outermost in the series so that I can easily remove them if they prove to be a bottleneck.
Note the cardboard and the rubber band to secure them while I solder.
Stacked together with cardboard in between. After this I just wrap them in cellophane to secure the pack a bit.
Voltage's all good ?
After that, I tackled the wiring. Rewired
@Thehack 's meanwell cables to my dc-ups. I just happen to shorten my dynamo's eps cables few days ago, so I double down them cables on each output pin on the meanwell. Made life harder because the screw connector is relatively small, but made it work somehow.
For the dc-ups's output I used the cables that theHack sent me as-is since it's bulky enough. That goes straight to dynamo's input.
Andd.....
IT LIVES!
Pack's load voltage in the first minute I unplugged the power cable.
Closer look at how everything is wired. The dangling yellow-black cable doesn't connect to anything, I'm not taking out the hdplex just yet.
It's been 45 mins, and I'm down from 23.5V to 21.5V. The weakest cell groups are still at 3.6V.
Load is writing this up and youtube playing in the background on autoplay.
But it's 5.0AM here, I _really_ need to sleep!
