Battery not charging after riding? Your main battery won't charge if it's too hot/cold. Ensure it is brought to room temperature and then the charging will begin.
When using two batteries, the batteries must be within 2% State of Charge (SoC) with each other before they will both be used simultaneously. If one of the batteries is at a higher SoC than the other, the motor controller will use the battery with the most charge first, until the batteries are equally balanced. The system will then automatically switch to using both batteries together in parallel.
