We recommend using a 12 V⎓ battery of 4 or 7 A⋅h. This type of battery requires special racks in the casing.
You can also use similar batteries of a different capacity, of the matching size and with a charging time of no more than 30 hours.
If the battery is charging for more than 40 hours, a notification will be sent to Ajax apps informing that charging takes too long. This type of event is considered a malfunction and displayed in device States.
The maximum battery size installed in the body should be 150 × 64 × 94 mm. The maximum weight is up to 5 kg.
