New Lipo: do you Repeat Charge / Discharge a few times before use?
#1
Anyone who actually charges, discharges, charges, discharges their new lipo's etc before use?
I mostly just charge them put put them on the quad and go.

but then I heard there is something called break in procedure, it goes something like 0.5C charge first, discharge to 3.7V, 1C charge then discharge to 3,6V, 1C charge and flying, gentle first.

just wondering what the benefits are?
I love to share and help people! Flying Mini Quad is the best!

The proper break-in procedure is (quoting from here )

Break-In Procedure:
  • First charge of 0.5 C up to 100%
  • First discharge at 0.5 C to 3.7 volts / cell
  • Second charge of 0.5 C at 100%
  • Second discharge at 0.5 C to 3.6 volts / cell
  • Third charge with 1C to 100%
  • Third discharge at 1 C to 3.6 volts / cell
  • Fourth charge at 1C to 100%
  • First flight assignment with moderate currents, so gentle style of flying, flight time to about 50 - 60% of discharge limit
  • Fifth charge at 1C to 100%
  • Second flight with the use of 70 - 80% of capacity with smooth flying style

All new batteries have a chemical stabilizer in them to give them long shelf life. The break in procedure breaks down this chemical. If you run them without breaking in, your batteries IR goes up and reduces performance/life cycles.

Its all a matter of preference, I know some people who can't be bothered by doing any of this. Just don't scratch your head at why that expensive battery doesn't performance as well as expected. Or doesn't last 400-500+ cycles.

I just charge at 1c for the first time and then go fly here Big Grin

First time I heard this.. wish I would have known before changing to 1C first time on all my batteries

Usually for me, what I do is for the first 5 charge cycle I do only 1C charge and then fly the pack until 50%, light flying only and repeat. It works for me so far.

For your information... I tested the break in procedure last weekend... I measured the internal resistance before and after the break in... and I found none to very little difference...

IR was measured in similar temperature, lipos were at same voltage level (3.8V)

What always stumped me when reading some of the more elaborate break in procedures I've read....like some have almost a dozen cycles on the lipo before they crank it up....is why I've not seen a peep from manufacturers of the batteries in regards to break in procedure. Only thing I've heard was straight from the mouth of a local manufacturer, Glacier, and was told to maybe take it easy on the first flight and after that fly it like you stole it. And now Joshua and Oscar have both tested and came up with the same results. But I'm sure this dead horse will continue to get beat. Smile

Of course it will, even some manufacturers of smartphones tell their users to "format" li-ion cells before use. That myth will keep on going for all the batteries Smile

This is my way.

Buy the battery
Charge it
Install it
Fly it
Drain it to 3.5 volts loaded
Charge it
Fly it and so on.
Easy peasy.

Hi,
I am new here and in the hobby :-). I read up a lot about LiPo handling but on the "break-in" topic I found so many different opinions that I am not sure what is better really. I would be super interested to see the "no break-in" video from Oscar you were talking about above. Can someone maybe give me a link to it?
Thanks in advance!

I just talked to custumer service at Venom and he said just charge them and fly them . try not to get each cell below 3.5v and you should be good .
