disappointing
disappointing I bought 8 Lifepo4 60 Ah cells and checked them individually by charging and discharging. I already have some lifepo4 cells from well-known manufacturers (CATL and EVE Energy). The cells delivered are significantly worse.They are much cheaper but unfortunately still a bad deal. Why? - significantly less capacity than indicated. I have measured values between 39 Ah and 47 Ah, depending on the discharge current. - approx. 39 Ah at 20 A discharge current and approximately 47 Ah at 5 A discharge current. - The cells cannot cope with high discharge currents. Discharge rates close to 1C (60A) lead to a significant (below 3.0v) voltage drop after a short time. I didn't even try 3C at all. - The packaging is good, but the cells still have scratches and small dents. That can't come from the transport. - The cells have different capacities and internal resistances. At 20 A discharge current I had values between 36 Ah and 41 Ah. The cells are therefore too different to be able to build a reasonable 24v battery from them. shortly: Significantly less capacity than promised and not usable for most applications due to the poor high current properties. Sending back to China is not an option due to the high transport costs that private individuals pay for dangerous goods. Was an attempt and failed. My bad.
