I have a Fieldmaster with Ctek 120s and D240se with a lithium Lifepo4 battery 300A as second battery. The duel battery system was set up at factory and I only replaced the original FEB battery with the lithium. This year I travelled through Simpson Desert and Around Alice Springs. The second battery was charged so well and there was no shortage of power for my rice cooker, induction cooker and water kettle. I did not see this error code when travelling. However, I have not driven the vehicle lately and the second battery got drained almost to 15%, which is the protection level. Main battery was almost normal at 75%. This error came out twice. My AI research came with this advice;
- Lithium low → aggressive bulk charge
- Smartpass opens
- D250SE demands current
- Trickle path allows reverse influence
- Voltage excursion occurs
- P0563
