I am facing with some challenges. Luxpower SNA5000 inverter and 3.8 kw N Energy Lifepo4 battery. When I select an protocol for the Lithium battery I do get the 80Ah and then the battery voltage show 5 volt on the Luxpower inverter. tried different pin lay outs on the cable and no success with anything so the only option that i have now is to run it with the lead acid option on the luwpower. If any advice or if some one can assist with the BMS software to change the port settings ( I read it in a Forum that it is maybe possible to fix the problem)
