    Tabless design cylindrical cells tests

    knowing my luck it would happen two weeks after I got them and they would be even cheaper lol

    Tabless design cylindrical cells tests

    They do mostly use Murata cells but some packs also use Samsung, Sanyo and LG cells.

    Tabless design cylindrical cells tests

    They should have been available even sooner, makita had some packs with tabless 2.5ah 18650s already shown in catalogues but then removed them some time after, best guess is that they were delayed for some reason.

    thanks, it looks awesome so far, better discharge curve than P45B and you can get it for 3e, awesome... hopefully its cycle life is at least decent.

    Wow these look like pure garbage, how did they manage that lol? And while 4860 looks to have a good cycle life characteristics, 4695 looks much better based on numbers alone

    Tabless design cylindrical cells tests

    interesting, a bit different info compared to this previous info: https://endless-sphere.com/sphere/threads/tabless-design-cylindrical-cells-tests.122072/page-3#post-1813928 So it't 30Ah which is also not bad, but now I am confused because Pajda tested P variant and got 32Ah, shouldn't this E...
