They also gave me this code for the 320 Ah model, though I have no idea if it's any good: https://eu.humsienk.com/FFCOSSAG12V320Ah

The default current limit of this battery is 300 A, even though it's only rated for 100 A. The internal parts are definitely not sized for 300 A continuously, so what happens when we try?
