Hey everyone!

I just got some new packs for me 700 and I was wondering what you guys recommend for breaking them in. I'm not a crazy 3d pilot anyway but should I just take it easy for a few flights?

Thanks!
Jay

Break-in ..

Charge 1 pack a at a time. (don't parallel charge)
Charge at 1C.
Discharge at no more than 5C.
Repeat 5 times.

Thanks, TheWoodCrafter

Break in....

-Place packs in helicopter
-Fly
-Packs are "broken in"

There has not been any scientifical data performed on the benefits or harms of what everybody calls breaking in a pack. I have never broken in a pack and I regularly get well over 200 flights on my big boys. 400 on a set of 6s Volts and 500 flights on a set of 6s Spyder packs. I am currently on 120 flights on a set of 6s Gens Ace packs and again, I've never broken in any of my packs.

Well, I have heard that before as well. I personally have never broke in a pack. I've just always charged them and flew it like any other one I have. Being that I'm building a stock of flight packs for my 700, some new, some old, and some used, I just want to be sure that I'm taking care of them the best I can.

Well you guys must not measure IR.

Doing so has proven that with proper break in the IR goes down.

1c charge and easy as you reasonably can be during flight for the first or first few flights is about as far as I care to go.

When someone does a scientific study with many samples I would think about it more. My lipos will either be worn out from use or taco'd before I reap any worthwhile benefit from crazy break in schemes

Wrong. I measure IR almost every flight with my PL8 and most of my packs come down with IR measuring between 0.8 - 1.9 and on the high flight packs, I was lucky to get around 2.4 per cell.

Show me your facts where it has been proven that a break in procedure is needed for batts and I mean scientific data. I don't want to hear "because company A or pro pilot xxx said so".

Not being ugly here or anything but I have heard of people putting 10 + cycles on their packs by charging / discharging and for what reason? That's 10 flights you could be enjoying!! I did charge my new packs at 1c for the first charge just to make sure all the cells will balance properly but after that, I charge all my packs at 3c and fly the crap out of them and again, I've never had an issue!!

Here is just one opinion of break in -

Brand new packs
New lipos ship in a "sleep" state. They have a chemical stabilizer in the cells that help them more easily handle shelf life, and are shipped at a storage voltage of approx 3.85V per cell. This stabilizer is lost when the packs are cycled, so it is important to let the packs remain asleep until they are needed.

Once a new pack is ready to be used, it needs to go through a "break in" process. Generally this means treating the new pack gingerly for the first few cycles, including charging it slowly (1C) and gently discharging it to 50% capacity for the first 5 flights. This does 2 things. First it makes sure the pack is in good condition and secondly it "loosens" up the pack for normal duty.

Note on break-in: I am seeing more and more forum posts about people trying to break in new packs on a charger. I recommend against this. Not only is it very time consuming but it is also wasteful. Instead charge a new pack at 1C and the go fly it. Take it easy and use the time to work on some basics like hovering in less comfortable orientations or slow, precise flying. Using a pack for break-in in this fashion gives you more flight time and gets you more useful cycles of the lipos. Just remember to take it easy.

That was from Chris site, TJinTech, https://sites.google.com/site/tjing...ipo-terminology

I follow most discussions over on RC Groups in the battery/charge forum.
Some of these guys are battery experts and have the data you are looking for.
Some of these guys have been testing batteries for years.

This is what I understand is behind a break in -

New, uncharged packs will have a lower discharge C rating than a pack with 10 cycles on it.
Because the IR is higher on a new pack than after 5 or more cycles.
The lower the IR the higher the discharge C the pack can handle.
If you exceed the true discharge C of the pack it will puff and may be slightly damaged.

Now your new pack may have for instance a true 20C instead of the 30C you paid for.
After 5 or even 10 cycles it will be at 30C.
When new if you exceed the true 20C it may puff the pack.

Ever hear of guys complain about their new expensive battery puff after only one ( or just a few) flight?

That is because they exceeded the packs true discharge C because they didn't break in the battery.

Do you have any scientific data that shows batteries do not benefit from some form of break-in procedure?

I guess you really can't call it scientific because I am not a scientist but I think 4 years of flying electrics from 2s to 12s qualifies. Like I said about a dozen other times, I have never broken in a battery, cycled a battery on the charger to break it in, or storage charged a battery and I have never had an issue. Then again, I have always used higher quality batteries. I can list my larger packs that I have had over the last 4 years and give you the flight data but that won't appease you so I won't waste either yours or my time.

This is a moot discussion because just like religion and politics, you will never see my point of view and I will never see yours and I will never agree with breaking in a pack and you obviously believe you have to and no matter what we say, our opinions will never change

A little testy aren't you.

Taking this personal too and taking yourself way to seriously.

I don't give a rats if you believe me or not and you are right, you can't appease me.

The OP asked a question and I tried to help by answering it.

I read somewhere if you take the batteries on a date and buy them a nice bottle of wine that they will last much longer.

To hover is divine, the alternative is rather PLANE.

It's not about having an issue, it's about being able to extract the maximum performance and longevity from a pack. If you cannot compare a pack handled one way vs. a pack handled another way then I don't see how you can say with any certainty which pack handling methodology works best to ensure the maximum performance and longevity from a pack.

For the record, I don't see how a few break-in cycles could possibly hurt. I go easy on my packs the first few flight or cycles on the charger and only charge at 1C for the first several flights.

From Thunder Power's info sheet included with all lipos:

"First few Flights
Thunder Power recommends no more than 3-5C average discharge for breaking in new packs."

3 to 5c discharge? Is that even possible?

John from Revolectrix just released an interesting video. Some questions and discussion about break-in followed.

John writes
thought i'd go into some detail to bust some mythys.

1. You don't need to pre-cycle batteries before playing
2. aging of batteries does exist. the longer the better...........
user 3d Dave replies
FWIW, this is still written on TP's Safety Data Sheet.

"First few Flights
Thunder Power recommends no more than 3-5C average discharge for breaking in new packs."
John responds
yup correct. 2 reasons for maybe wanting customers to pre-cycle.

1. the cells/packs are more than a year old. when the packs age the cathode plate re-builds the deposition layer and may need to be cycled a few times. only required if the cells/packs are over a year old.
2. the factory did not do formation. but i doubt this

Great video. Just think if they were made in the USA, they would cost 10 times the price with unions, benefits and higher wages.

Kinda of sad in a way, those people working their tails off to produce batteries so we can play with our toy helicopters. But on the flip side, thanks to them for making them affordable.
