Hi stmdude,
Thank you very much for your help!
Currently this happens after three charge/discharge cylces:
When I start the Raspi and let it run idle ("running idle"-what
did I wrote there......?
I mean: Only the kernel is running and a little script doing
some I2C to get the voltage and the percentage off the chip
from time to time) this happens:
The voltage level falls and I can verify the value with my DMM.
So no problem here.
But the percentage rises first and falls then but towards the
point I would shutdown/switch off, the percentage is way to high.
I use this table (posting #6):
https://www.rcgroups.com/forums/showthread.php?2366548-LiPo-80-rule-and-my-shallow-charge-ratesAccording to that chart, 3.69V is about 10% left charge.
But my board reports:
++++++++++++++++++++
Voltage: 3.65V
Battery: 30%
++++++++++++++++++++
You wrote, calibration is done by...MAXIM? So...do I need to send
them my board? Is a joke...or? OR?
What voltages would you suggest for a LiPo cell, which is currently
be charged AND slightly under load (95mAh - the linux is running reading the
voltage and SoC), has 1000mAh and is supposedly a Li*Po* cell despite
the writing on it saying "LiIon", as upper and lower limits to not to
do harmful things to the lifespan of the LiPo?
How many cycles -- roughly guessed -- I need before the Max17040 from
"wildly guessed mode" to an elaborated guess of the SoC?
And why LiPos are such delicate beasts?...
Thanks a lot in advance for any help!
Really appreciated!
Cheers!
