Is it OK to put the intelligent battery on the charger even when it's only about 25% down, or should I wait? I'm old enough to remember when charging partially discharged batteries created a "memory problem" resulting in severely limiting the battery life.

Since I have three batteries, I'd like to put the just-used battery on the charger at the end of each flight and pop in a fully-charged battery at the start of each flight.

So...charge the just-used battery regardless of level?

Many thanks.

I would actually prefer charging them when at 25-30%. Draining them completely on every flight will ruin the batteries alot faster.
I also put them right back in the charger (or give them a minute depending om temperature). This is in case of good flying conditions in the near future. Stored batteries will drain themselves when needed.

Yes.

Yes, that was / is true of some types of battery but that won't happen with these LiPo batteries.

They shouldn't be charged while still warm / hot immediately after a flight; let them cool off first, but yes, it's fine to charge them at any time after that.

You can set them to discharge in your app automatically, to just over 50%, no problem charging them if already partially charged, it's not a good idea to take of with less than 100% battery.

Great. Thanks so much.
