Could someone who is wiser than me clarify best practice?
What I tend to do with my (TB47) batteries is as follows:
1. After use, I fully charge them to 100% and then allow them to do an auto discharge over 3 days. This, I believe, takes them down to the 'safe' storage level of around 60%.
2. Recharge to 100% before use (obviously).
3. Every 20 or so charging cycles, completely discharge and then recharge to 100%.
However, on the Phantom Angel web site that The Editor kindly pointed to, it says: "Manufacturers (including DJI) state that LiPo batteries should be stored at ~50% charge if left for more than 24 hours. DJI’s auto-discharge function takes at least 3 days to discharge - that’s not good enough."
So, am I doing the wrong thing in recharging after use and allowing my batts to auto-discharge? Would it be better to leave them at whatever level they're at after use (typically around 20%)? Or is it bad to store them at that low a level?
Is the best thing to in fact invest in a Phantom Angel?
Obviously, given the cost of them, I want them to last as long as possible!
Thank you.
