I'm not sure if it's a recent update of repackr, but you don't need to enter comma delimited values. Just copying the values over from Google spreadsheet works just fine.
Very nice job. I build a small 12 volts 5p4s end use your work shit. Thanks, its very good job. Keep going. Now I preparing my cells for 10kw power bank. Its very long time to preparing and diagnostic my cells.
Any reason why you don’t use the “Click on a battery value to turn it green” function of the repacker output, and instead copy to a spreadsheet? It doesn’t seem like its saving you time since you have to go search the database for the cell ID anyway.
@Frank Brand I have a pool pump that need 110 volts to run. so I'm looing to build a powerwall that can supply that. I'm I looking at packs with 31 - 32 cells ? I would appreciate your answer?
I'm guessing that is 110 VDC if so you will need an inverter. DO you know if you want to build a 12, 24, or 36 VDC powerwall? You can email me frank@thediyengineer.com
i sort my cells in groups starting from 1300mah, 1400, 1500 all the way up to 3000mah in bins. anything under 1300 is just about worthless unless they are that capacity from new and I'll look up the model number. I have over 200+ cells and growing each week.
That is a great start. Where are you getting most of your cells? When you get ready to start building your project(s) you will find my Cell Pack Calculator helpful. thediyengineer.com/get-cell-pack-calculator
I go to a local recycling place and pick them up when i can find them. I also trade pc stuff for batteries at a local pc store/repair shop. Sometimes I get a half dead pack sometimes good and sometimes all the cells will be dead. If there's more then 100mv in them i will put them in my home made charger board and see if they charge with ought getting hot. If they pass that test then i bring them up to 4.25v and leave them sit for a week or so, check the voltage and put them in my discharger to see what the capacity is. I then bring them back up to 4.25 and store them, later when I make my packs i'll check them again and any cell that discharges below 4.10 will go back to the recycling place.

Thx very useful, lol a little OCD hopefully you'll do some of the physical build as I'm new to this and all aspects are helpful thx again.
Hi, signed up but didn't get a spreadsheet, double-checked spamfolder also.

Samuel, Thanks you.

Hmm, I probably need to give that some thought.

I purchased 200 new cells advertised 3000mAh so far testing shows less than 1300mAh is this normal for new cells or did I get robbed
You got robbed -- lol
