DATOUBOSS LFP48-314-FSD 51.2V 314Ah LiFePO4 Battery, 16.07 kWh, EU (SP-DT-LFP48-314-FSD-A-EU)
So far so good
I have now bought three of these here in the UK. There have been reports on the forum of people receiving units with cells without clear markings/QR codes. I've opened two of mine and they've all had clear factory QR codes. The cells are from 'Great Power' and even the third unit that I ordered several weeks later appears to have cells manufactured on the same day. The BMS is from JBD and after a lot of trial and error I found the appropriate Windows software that allows you to monitor and tweak the settings on parallel packs. The only issue I had is that with the batteries and my Solis inverter set to 'PYLON' as the protocol, the inverter threw an error for 'battery name'. I eventually tracked this down to a field in the BMS settings and was able to update this to what the inverter was expecting. No issues connected over CAN since. Once I tweaked my charge voltage, they charge well, although some cells are a bit out of balance and the voltage spikes on them at a high state of charge. I now have this under control and the passive balancing is slowly doing it's job. An excellent choice if you don't mind tweaking a few settings and learning as you go.
