Good afternoon. My PING batteries have finally died on me and I am now looking at buying/building replacements for them. Been looking around and I quite like the look of these cells from EVE which have threaded ends eliminating the need for soldering or welding. EVE C40 40135 - 20Ah - 60A LiFePO4 - 3.2V - Prismatic - LiFePO4 - Rechargeable batteries | NKON
They seem to have quite decent energy density (for LifePo4) of 170.88wh/kg (though that excludes busbars, holders, casing and BMS)
They seem quite cheap at 10 euros each (if buying a fair number of them, I would be buying 32 to build a 51v, 40ah battery, 2p 16s), so 320 euros for around 2Kwh of cells
I have tried searching the forum but cannot find any mention of these cells. Has anyone looked at them and discounted them for any reason?
Was wondering if I could re-use the BMS from my old PING batteries (signallab v5)?
