BH posted today a couple interesting options for large-format LiFePO4 cells that are a great deal, especially if you're planning a small car EV or larger E-moto.
Problem is, these cells don't have studs, bolt holes, or thin tabs for assembling a pack. BH recommends in the description that they're good for people who can aluminum weld or have a laser welder, which I'm sure some people have, but not most.
Anybody have any other ideas on how the average joe can use these cells? I thought that it'd probably be possible to solder to the contact surfaces, but not only would it take a ton of heat and solder, it's not the best idea for EV's that experience a lot of vibration. So maybe that would work if someone would use the cells for a stationary powerwall application.
3.2v 105ah Lifepo4 Prismatic Battery
These batteries were recovered from modules that had a bad laser weld. We tested 40 different batteries and they all tested above 95% capacity. It is likely they were never fully cycled since the laser welds were not done properly. They have aluminum tabs on them. If you are comfortable welding...

12.8v 105ah Lifepo4 Battery - 4x 3.2v 105ah Prismatic
These modules are pretty awesome and unique. They are 12.8v 105ah lifepo4 modules. The company that made these had issues on some modules laser welding the flexible PCB busbars on top. There is a chance these module have never cycled and the batteries we tested were all above 95% capacity. We...
