[!CAUTION] Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.

Integration ongoing :low_battery:

/* TODO: This integration is still ongoing. Here is what still needs to be done in order to use this battery type

  • Figure out contactor closing
    • Which CAN messages need to be sent towards the battery? */
