      On another Rockster (#RockRep2019) the MOSFET and diode of the fourth phase were defective. In that case, there is an option to convert the 4-phase boost converter to a 3-phase boost converter. (This could cause problems at very high music power in battery mode, because the other phases carry more power and become warmer).
