Hi, it's the current generation of Daly 250A BMS. It should be this one. Seems to work pretty well so far. Since it is possible to set the temperature, I'll test it by setting the low-temp charge protect slightly above ambient temperature and see, if it closes the charge MOS. If it does, I'd...

That's correct. But the above numbers are cell voltage masured by the BMS, not the voltage set at the charger. So by the time they reach those voltages on cell level, they should have the respective SOC if I am not mistaken. #1 You're absolutely right, I can definitely not compress them at that...

Interesting. Those numbers were roughly based on the SOC charts I found here in the forum. My plan is to keep the battery between 10-90% SOC for longevity. Guess I will have to play around a bit and cycle test it a few times with slightly adapted settings until I hit the sweetspot. It listed...

Then I can't quite follow. One would be the cell expansion and compression during charging/discharging for longevity. Given that the metal case size is what it is, I can really only compress them with the filament tape which does have a pretty strong tensile strenth. So hopefully, this will not...

Hi, thanks for your feedback. Do you mean movement between the cells or for the whole cell pack within the case? The pack has rubber foam layers between the cells and I wrapped it with like 20-25 rounds of filament tape as strong as I could. There wasn't any movement at all when picking it up...

Hi all, as a long time reader and now, first time poster, I have just built my first LiFePo4 battery with 304Ah Eve cells. Find below some pics and specs. Happy for any constructive feedback or if anyone spots a mistake. The battery is intended for our offroad vehicle EVE 304AH cells with...
