It appears that theLGGBM261865/LGEBM261865 (2600mah) are a favorite by manufactures for scooter packs.
I see more and more of them popping up on the salvage market.
I'm guessing they are NCA chemistry as the IR is midrange ~35m? AC. Will get DC IR on the next batch.
I have yet to find a spec sheet to confirm that though.
I have 1592of them tested and had 20 duds.Most because ofphysical damage, some to SD and high IR.All the rest very nice results.
The sheet of the study and testcan be found on my google drive here.https://drive.google.com/file/d/14y1mxVqPn1UDCsqs9g1eDxEuWrLBEn54/view?usp=sharing
