Real life capacity at discharge to 3,0V (@1,5A=ECO mode) - 43V*3*5,3Ah = 680Wh
And this is the correct approach to the battery capacity! and to be honest, at the moment I am planning exactly the same 12s3p configuration using exactly these LG cells.
I'm waiting for the frame and I have no way to check, please tell me:
1. the battery cells must be slightly offset from each other to fit into the frame? is the maximum external size of the battery max 65x55mm? (can You send the finished design/drawing of cell arrangement?)
2. Did You weld with 0.2 mm pure nickel plates? or others?
3. How did You attach the package to the frame?
4. Which BMS company did You use? - I'm considering BeMuchSafer or JBD and I think I'd like something with Bluetooth.
If You can, please send more photos (or all) of your battery pack implementation.
