DJI Avata Charger : Battery Monitoring

thingiverse

Have you ever wanted to monitor the charge of your DJI Avata battery ? Have you ever wanted to automatically stop the charge at any percentage you want for storage ? (without letting the "smart" DJI battery to charge 100% and then to self discharge to 60%...) Keep the hand on your battery : it's simple. Details on my hackaday's project : https://hackaday.io/project/189188-dji-avata-smart-smart-charger Video of the device running : https://youtu.be/21gmuOZC5eo Video "outside the box" : https://youtube.com/shorts/oBY43TFwshM An ESP32 simply monitors the charging parameters which are sent to an android application written in B4X language. It gives access to : - current - voltage + indivual voltage of each cell - capacity of the battery (remain and full charge) - percentage of charge - temperature You can set an end of charge percentage to stop the charge automatically for storage mode. Works with Avata's chargers without modification. Most of the credits go to Aircuiser. He reversed ingeneered the DUML protocol between smart charger and smart battery. Impressive job done !
