Well, as you probably expect it, I’ve changed my mind again. Turns out, I won’t have enough space for the NESE in the evo. I am ordering a set of PCBs from @akhlut and actually building the battery myself.
I pulled all the batteries out and my 737 sealant and started going at it!
I just finished gluing and putting the fish paper rings on each P group just now.
My nickel strip should be here tomorrow. I got all the PCBs glued up with the P groups. So just waiting on my nickel and I can get going on welding the packs all together.
Ohhh yea. I forgot something. Remember to test the welds before you make the welds in the pack.
A good rule I’ve found is you should definitely not be able to rip nickel to battery welds apart with your hands. Be aware, nickel strip is sharp and can give you “paper cuts”. If the weld is strong will it leave, the nickel that got welded to the battery, on the battery when you rip them apart with pliers.
And for nickel to nickel welds, if it makes a hole in the nickel strip when you rip them apart it’s good.
Unless you provide pics i will not believe that you and @Sender are not the same person. Both of you in the same room at the same time. Pics or it didn’t happen
Nickel strips got delivered today, doing the scratch and saltwater test over night and then hopefully will be spot welding some P packs tomorrow night!
Oh man, finally read through all this. Your journey has been just that. I’m pumped to see how your battery building goes. That’s next on my list for skills to learn.
Told you man!! This has been one hell of a journey. I’m going to try and have the battery finished this weekend. My workbench carpeting turned out pretty good!
Got everything spot welded, now jsut slowly soldering the cell level fusing on. I have 4 of the 12 packs finished.
Once thats done, gotta wire up my BMS! I have all the supplies to keep this tight and safe so no worries there, its just a matter of getting spare time to work on it!
