Based on what's in the manual, some You Tube clips I've seen and experience, this is what I do.
1. I don't store my batteries fully charged.
2. I charge the night before or on the day I go flying.
3. This means I store my batteries with a 10-30% charge.
4. I set my discharge period to 3 days.
5. I don't store a battery in the drone when not in use. If the battery should fail and swell you won't be able to easily get it out. If the battery should burst then who knows what damage it will do.
6. I perform a deep discharge about every 25-30 charges, as recommended. The way I do this is complete a flight and discharge the battery as much as I can, then leave the battery on (in the AC) until it goes out. According to advice the battery will still have a 'real' approx. 10% charge left.
7. I make sure I charge batteries inside the working temperature envelope for the battery.
8. I keep an eye on battery operating temperature. Particularly I don't want them getting too hot while running (=discharging).
What I know:
1. LiPo batteries don't have a memory.
2. These LiPo batteries are good for approx. 100 charge cycles.
3. If you store a fully charged battery and it slowly discharges you lose one of these charge cycles. You don't need to.
4. Never fully discharge a LiPo battery. And I mean FULLY discharge. The battery management system will have difficulty restarting and recharging the battery.
5. If LiPo batteries are charged too hot or too cold the resultant change to the battery chemistry effectively shortens the battery life (read charge cycles).
6. At AUS$250 (that's Australian dollars) I want to get the most out of my investment.
Hope this helps. Yes I know previous posts in this thread cover some of this. I just like to share. As you can see by my avatar I might be just a little obsessed by my drones batteries.
