Hi,

Althogh the manual says you should store a battery at 50-65% if not using it for a long period, it does not say anything about storing for a few days.

Currently I can only fly me P3 during the weekends.

I usually start to land once the battery warning starts (at 30%), so I end a flight with about 20-30% battery

If it is the last flight for the weekend and I know I will only be flying again in about 5-6 days,
is it OK to store the batteries as they are, with about 20-30% charge or should I charge to 50% and store?

Are there any suggestions for this situation?

Thank you,

Thanks for the reply.
I just wanted to know if leaving the battery at 20-30%, when I know it's just for a few days might be even better than charging to 50%, since the load on the battery's chemistry is even lower. I don't understand the chemistry, just wandering and trying to apply common sense.


In a few days there is no risk of reaching an under-voltage situation.

If leaving the battery as it is for a few days is better, this knowledge might help lots of people with the same usage profile... those who can't wait to fly but can do it only on weekends.

The "storage value" (50 - 60%) is where it stores best. Perhaps coincidentally, that's half-way between zero and 100%.

I can pretty well guarantee you if your battery is stored at 50%, it will retain a reasonable voltage level for a surprisingly long time - weeks, if not months. If you store the battery at a 20% level? I have no idea, but I'll bet you're either flirting with a potential problem or it's just going to take longer to get your battery recharged.

Storing a LiPo battery at 50 - 60% is the "de facto" standard. Better safe than sorry.
I agree with Rebel - it's all about chemistry, but there's gotta be a good reason why *everyone* seems to agree that LiPo batteries should be stored at 50 - 60% charge.

OK guys, you convinced me. From now on I will store them at 50%. Thanks guys! Happy and safe flying.
