This cell was a failed cell from a Mitsubishi iMiEV battery. They are nominally 3.7 volts and 50 Ah.

Interesting that they wound up two separate accumulator piles and fused them in parallel, versus one big one. I guess the form factor might make it a little more energy dense. Alternatively, they may have 25 Ah and 75 Ah options down the line...

After 2012, the improved GS-YUASA, LEV50N , having a different electrolite..

Aparently there are 75ah, 50ah, and 40 ah versions of the GS Yuasa LEV cells
The Mitsi Outlander PHEV uses a 40 ah version of this cell 80s, 1p config..12 kWh.
Nice video of the pack being dismantled...
