Problème batterie DEVO12S ?

Est ce un problème de batterie ou autre chose, merci.

Is this a battery problem or something, thank you.

Vidéo :

No video.
I see only a black box containing the words, "Blocked Plugin".

On some Modules like Frsky it can be very jumpy. Try the Test on dsm2 . May be some Overload on the main Voltage Regulator.Most time with the cc2500. Some one used a dc to dc converter to power the modules on the 1 s Lipo Tx Vesions to get a relatively stabel Voltage

test on DSM2, idem. When y touch the screen the voltage down.

I will try a full discharge on my lipo charger to see.

I just made a complete discharge, I unloaded 2700mAh.

I recharge 2730mAh

Is there a difference between the charger and USB charging ?

With USB Charging i can't go to 4,2 v (4,12v max)

i don't know about the 12, but some inside Charger do not charge to 4.2 because the Cycle Live is longer below 4.2

-> 4.2 V around 350 Cycle
-> 4.1 V around 1000 Cycle

on normal Lipos ( thumb rule)

may be here is the same Thing done to get more Cycles out of the Lipo

but if your Lipo getting old the internal resistance is getting higher ,then it charge to 4.2 and some seconds after the full charge it drops fast to a lower Voltage.
If i do testing my Charger i measure the cut off Voltage at the charge State and there it should stay at 4.2 or a little lower at the End.

btw . a Lion Batt is full at 4.15 ! Only Lipo is 4.2 <- care full here to not kill your Batt

only my 2 ct.
greeting Alex

Mine does the same thing. I always just assumed it was a software quirk. It hasn't seemed to hurt anything on mine.

Quelle tension d'alarme as tu mis ?

What did you voltage alarm set ?

3.6V.

Ok ! by default it is 4v

how long she works ?

Can't say I've payed enough attention to time it.. But it has no trouble lasting a full day of flying. I've got two batteries, and have only had to use the second when I forget to charge the one in the transmitter. I bought my second battery from here: www.dx.com/p/walkera-bt3000-3-7v-3000mah...evo-f12-black-331708
