Lightbulb 1000 Laptop Cell Recycle Job

Half way into the process of evaluating a large batch of LiPo cells ... the deal for my chosen motorcycle, for electric conversion ... fell through.
So, might have some tested and rated cells available ... ?

Self-discharge testing about 1000 2.16Ah cells.
(3.7V x 2.16Ah x 1000 = 7.992 kWh)

All cells in each stack precisely equalized to within 2/1000th V.

Wove tinned copper braid in parallel of closely voltaged cells ... to precisely equalize

Discharged 1st batch as 30s2p using 2 60w light bulbs for a 1 Ah per hour capacity test.
120V DC electricity can be very dangerous - use extreme care!

Nearly 1000 cells running self-discharge test

Finally started evaluating the Dell packs that used the Sony cells


Will eliminate any self-discharging cells;
test all cells for a comparative IR;
confirm all banks in each pack of same IR;
run 30s discharge evaluations (discharge capacity test).
