Both sensors (horse’s and rider’s) can be recharged via their micro-USB port. This dual cable allows to charge both sensors at the same time.
Sensors’ operational autonomy is around 20 hours. In standby mode, battery life is of several days. However, we advise you to charge them regularly.
To properly charge the sensors, use a recent adaptor with a 5V output.
The dual cable is included in the Start Pack. You can buy it here per unit.
