any update on the teardown? you might try acetone on the glue to soften it.
Double bump! Wonder if really a compression pack. And what pressure. What the materials are.
Sorry after the last post I never figured out a way to get the plastic cell enclosure out of the shell. And now Iām busy with schoolā¦
and/or a hairdry to soften the glue
Maybe these are actually 21700 Li-Ion cells ? Iām betting on Samsung INR21700-30T cells arranged in 13S2P ? That would make up for a max discharge rate of 70A (max 35A per cell), just like with the 12S A123 Pack of M1a cellsā¦ But total capacity would be 6.0Ahā¦ Or maybe 5.7Ah if you donāt fully charge like boosted does (charging up to 54.4V instead of 54.6V)ā¦
We wonāt be absolutely sure though until someone dares to open it.
Any new news on what cells these are?
