4s JBD 100Amp setting to maximize surge current?

Have a 4s JBD Running my ~250W air pump. Recently had to change inverters and now the surge at startup is causing the inverter to fault.

I have tracked it down tot he BMS because if I move my GND cable to the battery itself it works fine and the Older inverter worked fine for years.

Now I've tried to change the app but I've noticed it doesn't make any difference in performance. ALso On the app Its not reporting any overcurrent or Short Circuits.

Anyone figured this JBD out to maximize its output?
