    Is the P2V manual correct, recommending a new battery after only 300 charges?

    Battery cost of approximately $170.00 USD each divided by 300 flights is about .57 cents per flight.

    After 3 weeks with my P2V I must have about 50-60 flights already. And don't forget you need to completely discharge the battery every 20 flights or it's even less time on the battery life.

    Is this correct?

    I suspect that they mean 300 charge cycles. If you drain your battery each flight, then yes, that would be 300 flights.

    Sometimes you have to pay to play. ;- )

    Well I don't think it is 300 flights and "case closed" just like the manual say.

    Lipo's usually start degrading about then (300 charge cycles) so what would happen then is that slowly you will get less and less flight time. now to be on the safe side and to insure your bird does not fall out of the sky it is good practice to replace it on time. Now if you take good care of your batteries you can get more than that. Again, all of this at your own risk of course.

    Bottom line is batteries "Usually" start degrading before they give up.

    We are on our 4th set of these Lithium Ion's after a little over 7 years. One thing we have found is they also have a time life of around 2 years from first use. Another thing is when they are done, they are done, with little warning. They work fine and then simply will not charge beyond 2 bars and would only last about 2 hours as opposed to nearly a full day.

    I'm wondering if there isn't something built into the "Intelligent Charging" system that determines this to prevent over cycling problems for which Lithium's are famous.

    The Vision uses lithium polymer batteries, not lithium ion. They are different. I don't know the life cycle difference between the two, but probably not the same. I have heard others say that they have lipo's that they have been using for five or six years and still going.

    It's probably just a liability statement. That's the mark that the battery could start degrading, so maybe they warn you beforehand so you don't try to start a class action lawsuit?

    What would be sh*tty is if they set a limit in the firmware so the Phantom wouldn't start after a set number of battery cycles.

    Imagine if the Phantom would flash a warning LED when the battery reaches 300 cycles, then completely refuse to start after, say, 330 cycles.

    My own post from a while back in a different thread, but I still feel this way...

    All interesting observations. Not knowing any better in the first few weeks of ownership I ran the battery's down till literally 12%- 15% and fought landing with stick up till the end, now I am landing at about 20%.

    Thanks all!

    Great information about Lithium batteries, more that than you probably want to know.

    All R/C hobbys R expensive in my experience! But this one is one of the best "bang for the buck" so to speak I M H O.

    It's like the guy who questions the MPG of a Ferrari?
