    Paid $149 per cell, shipping included - directly from Docan's website. They are the older type with welded studs.

    Hey all, newbie here. Purchased my first 8 EVE LF280K cells from US stock a few weeks back and they aren't pulling full capacity. Seller says that is normal for 2022 stock. I patiently did a top balance and a capacity test from 3.65 to 2.5v. Got about 268ah with a load of .5C. I've now also...

    Sorry, just seeing this. This is very odd, did you figure out what was causing it?

    For the 5C test I used the JBD bms's metrics for tracking ah capacity and a Kisae pure sine wave inverter running resistance loads. For the 0.1C test I used the capacity tester you get from amazon, the ones that go up to 185w. I spent some time calibrating the voltage and current on the tester...

    Something I found when when testing the heating function, but didn't get around to posting about it until now. I didn't find anything doing a quick search so I hope this isn't repetitive info. When the low temperature threshold is met, the BMS will disable the charging MOSFETs and, instead...
