you should just do 2-3 cycles on each pack doing hovers. after that go for it. but thunderpower did tell me to do this.

I also do a few "easy flights" before going full blast

usually first flight 2 min hover

2nd flight 4 min of circuits

3rd flight 6 min of easy flying,then you are good to go

I look at it this way,it doesn't take long to break a lipo in and then you know it is done,as opposed to not breaking it in,and hoping it does not do any damage

I have seen some manufacturers say to break a lipo in,some dont,so I do just to be safe

I charge then fly.
But my first few cycles are at 1C then I go to my normal charge rate of 2C. I have no evidence to support that my way makes ANY difference, just how I like to do it.

I put the fun in dysFUNctional :)

I fly easy for about 5 flights leaving around 50% in the pack. I only charge at 1C or less.

I found this at the Common Sense web site.....

How to Get the Most From Your Lipos
• Cycle your packs when you first get them. Cycle them at least 3
times at low rates. Charge at .5C and discharge at 2C
• Try not to discharge your packs beyond 80% of their capacity. For
example try to use only 1600mAh of a 2000mAh pack. This will keep
the temperature down and prolong the life of your pack. Do not fly
your plane until the “low voltage cut-off” kicks in.
• Balance your packs after every flight. An “out of balance” pack and
a perfectly balanced pack look exactly alike. Charging an “out of
balance” pack one time with a conventional serial charger will result
in overcharging some of your cells and will do permanent damage.
This will shorten the life of the pack quicker than anything.
• Whenever possible, charge your packs at the slowest rate you can.
Of course, Lipos should never be charged unattended, so choose the
slowest rate that will still allow you to keep an eye on the process.
All battery types respond better to a slow charge.
• If you have any questions, try our “Live Help” feature located on the
top right hand corner of our website and you chat one on one with a
Lipo specialist.

Ive stopped doing any brake in after flightpower crew went out saying it wasnt needed on todays cells.

I havent seen any change in cycle life on any of my packs...

Gone fishing..or hunting..or something

I just charge and fly. First few flights I am very careful to only run about 60% of the capacity and avoid full collective. I prefer flying eights and circuits to hovering with a new battery - the current drain is actually less in forward flight.

I haven't cycled a lipo for several years except to verify when I think a battery is faulty. Cycling does nothing good for a lipo as most chargers over discharge when cycling, and the life of lipos is actually measured in cycles anyway...
