I want to keep my 380 with me so I can grab a flight on some down time. How long is too long to keep a lipo fully charged?

Good question... I'll be anxious to see what others say.

I would suggest - less is better. The less time a battery is fully charged, the better off it is. Practically, there are 8,700 hours a year and my batteries only last 3ish years no matter how I treat them. A few hours a week can't be that bad for 'em.

I seem to recall a table / article that showed the different deterioration percentages at different voltages. Perhaps look on battery university, or Google Lipo deterioration.

I believe a Lipo at storage lost 2% and at full up to 10% of its capacity. However the period was months or more and not hours or days.

If you keep the battery stored at 50% , it takes about 30 min to top it off..... Best of both worlds.....

Been there, done that and old enough to know better.....

I personally don't leave mine full longer than a week but there again I buy cheap Li-po's. Maybe only charge them to 90% if you think you'll be leaving them longer than a week. It will not ruin them half as much as heat or over discharging them.

60% of the time, it works every time!
