Yes, the wheel adjusts. I guess your idea of adjusting everything (except the headrest) every 30 minutes or so is one solution. It might work adequately. I could also put a firm 1" pad on the seat, moving my whole body forward, which would effectively reduce the headrest angle. Might cause ot

Hi John,     Your very nice Orion BMS will balance your batteries in standard manner ("top" balancing, so to speak.)  Orion makes an outstanding (and a bit pricey) battery management system, with all the bells and whistles if you wish to use those features.     Attempting to perform some sor
