You can connect any battery with the operating voltage of 4.2–10 V to the hub using 6V PSU.
We recommend using zinc-air alkaline batteries for extended autonomous operation. Before connecting such a battery, remove the stickers or open the air shutoff valves. If possible, leave the battery with access to the air for up to 2 hours. This will trigger a chemical reaction inside the battery and ensure proper functioning.
Below is a list of recommended batteries with guaranteed compatibility.
