Does anyone charge their LiPo battery's using Lion setting's?

No...but I have a charger that has a LiPo category. I'm curious why you're asking.

I have heard of others doing it to give the battery a longer life. Maybe its just nonsense.. I just was curious if others here do it or know of someone that does.

Is this Bull..

Charging always to a lower voltage than 4.20 volt /cell like 4.10 volt will extent the battery life dramatically (500-800 charges for 4.10v instead of 200-300). Note that the lower you go the less charge the battery will contain ( 4.10volt = about 85% of C)

Charging at lower than 1C (vs higher) and discharging to 3.5V per cell (vs lower) as well as discharging at lower current (vs rated) is a proven fact towards longevity.

What he said. It's proven too. Not just theory.

Show proof....

That using the Lion setting is better.

...this is obvious... anytime you put anything through stress, that stress has an impact on the internal chemistry of the pack.

by virtue of what you stated, keeping a pack between 3.8 and 4.0 per cell would give you thousands of cycles and charging/discharging at sub 1C... duh right?

but there is no free lunch... by charging to lower levels you have also reduced the amount of energy stored in the pack, therefore sacrificed a few minutes of flight time...

there is a sweet spot however where we can charge at a max level, discharge at a max level and get the most cycles from the pack while getting the most flight time. what that is depends on the quality of the pack and a host of other variables.

my take: charge as you wish, the key is to have fun flying... not turn "pack maintenance" into a hobby.

showing a preference will only get you into trouble, 90% of everything is crap...

I just asked for some scientific proof.....rather than an opinion....

If that is a better way, I would like to know....Lion charging, that is.

Never heard of it !

I certainly agree with operating lipos with a voltage range of 4.10 - 3.7 volts or 90% -30 % and keeping them near room temperature when possible.
Additionally I don't see the point of charging at more than 3C. I can wait 15-20 minutes to recharge. Especially when you have multiple batteries.
The way my 500's are set up I get 6 1/2 minutes operating lipos between 4.10 & 3.7V

I have a 3 year-old set of nanotechs still performing very well. Only slightly puffy .

It doesn't take much to hurt them.
Too much heat or over discharging is all it takes.

spending time, paying attention

I agree with that.....I don't fast charge, but rather have multiple packs.

Fast charging does reduce life expectancy...

The fact is this... push anything over its intended design parameters and its designed life expectancy will diminish.

anything you do to diminish destructive stress increases lifespan...

Lipo Packs are no exception.... reduce wear and tear, extend their life.

I have many and more many 4s 1350 that have over 600 cycles and no problems. Charge them at 3C and discharge to around 15-20%. They seem to love it. I do not baby my packs like some. I try and get 25-30 flights a day. Granted they are around 3:45 sec flights.

That's about 20 days worth of charge cycles....right?
