Is the Smart Battery too smart?
"DJI Inspire BatteryDJI Inspire and Phantom batteries will automatically discharge to their storage capacity when left idle for set number of days. When this discharge process begins, both the built-in and DJIGO app battery indicators may show the battery at full capacity while it is already partially discharged (the capacity is derived from cell voltage, which may trick the drone into thinking that the battery is at full capacity). When the current is drawn, a sudden mid-flight drop in battery voltage occurs. To test this theory, I took four batteries on their first day into this discharge cycle and tried flying them on a cold day. The battery LEDs still indicated full charge, the DJIGO app showed them at 94-96% capacity. All four batteries have dropped to 70-80%within first minute of the flight, and then suddenly dropped to 3-6% forcing an auto-landing. This convinced me that this theory is correct. To mitigate this possibility, monitor the number of days till the battery enters the discharge cycle, only fly fully charged batteries, and hover for 10-20 seconds at the beginning of each flight and watch for any unusual drops in voltage. Many owners limit their flying in the winter, which means their batteries entering the discharge cycle more often, increasing the number of these incidents during cold season. This seems to be the most plausible cause of these battery related issues.
I found this on on onother site recomended by a forum member : mydogisdead , I think it is just good concise information that i wanted to share
Safe and fun flying everyone - donnie
