You maybe correct & it would explain why DJI doesn't provide an obvious way to discharge their batteries. Historically (been flying DJI drones professionally for 10 years, early phantom, Inspire and Mavic) it has been necessary according to DJI and battery experts to discharge the batteries fully after 20 cycles or so (DJI used to say 10 cycles) in order to recalibrate the cells to the same level. As you may have observed, the drone doesn't draw down on all cells equally. On the Mavic 2 it draws down on cell 4 a lot more often than the other cells (Mavic 2 & Enterprise Dual). This being the case for most multi-cell Lithium ion polymer batteries.
The Intelligent Flight batteries have a built-in processor and firmware that does several things. It prevents overcharging, over discharging, getting too hot, does not allow charging when the battery is either too hot or cold. It balances the batteries and auto-discharges at a proper rate when idle for more than a day. Let the battery firmware do its thing and you will be fine. |
