Thanks for that. I have tested 3 cells so far, 2,527mAh, 2,490mAh and 2,493mAh. They are around 50m Ohms and charge to 4.1Vdc, but have been sitting on a shelf well over 6 months, so they have naturally degredated "naturally". But I will continue checking them all. I am using a SkyRC iMax B6AC V2 at the moment and wish to buy a 4 bay chargerLGGBM261865 are 2600mAh cells I have tested thousands of them almost all have been testing at 2600mAh or higher. The LG M26 series cells are all 2600mAh cells
Yeah 46 to 44 ohms to be more precise. That link doesn't work for some reason50mOhms is that with the iMaxB6AC V2? I haven't read how they accurate they are? Is the imax a 4 wire IR tester?
All of mine came from 9bot battery packs (electric kick scooter). The bms had shut down on the packs, 90 % were good cells. The average IR was ~37mOhm So I bet your cells have a lower IR than the tester says. if you want to learn more about IR testing check out wolf https://secondlifestorage.com/index.php?search/64240/ he also tested loads of the LG M26 cells.
