[QUOTE="The Editor, post: 15039, member: 82"] For those of you new to DJI 'Smart' batteries this is normal behaviour. All lipo packs loose capacity over time whether you use them or not. The internal resistance of the cells increase, they drop in their ability to give up a charge so readily and generally deteriorate with use. This has been well known and managed by the RC model flying community for many years and with those years come experience of how to charge, maintain and look after lipo chemistry packs. But then along came DJI and with it a new breed of RC flyer was born. What DJI did with 'smart' packs was try to do a damage limitation exercise for individuals not versed in how to treat a lipo battery. Without the smart technology many would destroy a battery in a matter of days and not have a clue why. Unfortunately, DJI's algorithms are a little over zealous in how they calculate loss of capacity within the pack and what you are seeing is those algorithms report a lower value almost every time you use the battery. You will see a similar post over on Inspire Pilots (with a similar reply from myself) together with how we managed/mitigated the loss. [URL='https://inspirepilots.com/threads/i-want-my-mah-back.9441/']I Want My mah Back![/URL] Unfortunately, the Spark packs are sealed and therefore not easy (or even worthwhile) expending the effort to get to the individual cells. They are also relatively cheap packs so treat them as what they are which is consumables. [/QUOTE]
