Now I am confused, how does the TH batterys come up with 16.6 volts. I know I'm just an old country boy but how does this happen?
16.6volts out of 12 volt system

lipo chemistry always charges over 0.5 volts per cell of the nominal rate it discharges at half a volt of the nominal.
Each Typhoon battery has 4 cells rated at 4.2 volts full charge.
The batteries are called 4S because each cell is wired in series,
so (4.2)+(4.2)+(4.2)+(4.2) =16.8 volts max charge.

That's okay! Just wash em before you touch your sticks!I had to use my fingers and toes!
DFT, the charge voltage full is 16.7-16.8 v 4 cells at 4,2 volts each is what I have been getting
For some reason I'm only showing 16.6 on my ST16. I have figured out that stated voltages on the outside of the batteries is the storage amounts when you let them set up.

Mine only shows 16.7 v right off the charger, Not a big issue , as they drop .2 points after 1 minute and then settle down!
The reported voltage of 3.7V per cell (or 14.8V) is the nominal voltage. Not the max charged voltage.
Think of this as "half charged" voltage.
They charge above this voltage, so the H charges to 4.20V/cell (16.8V) and should never be drained below 3.3V/cell (13.2V) This will really HURT the battery.
As a rule do not let the battery EVER get below 13.20V.... I will never let mine get below 14.0V (3.5V/cell )
If yours is only reporting 16.7 you may not have conditioned the battery properly but that is very close so I would not worry.

Good info. Can it be under reporting on the ST16? I know how I conditioned mine so they were done right. They flown to 14.8 then to 14.6, then finally 14.4. They have always been 16.6. I have a g.t. Power A8.im wondering if I should use this?
I have conditioned about 16 lipos in my life, and mine from Yuneec read 16.7v from the minute after the 1st charge out of the box! It does not concern me," BUT" it was conditioned properly !

The best I can get out of the stock charger is 14.7v. Been that way since the first charge. I always check the voltage with a DVM. I have 2 batteries and they are both the same charge.

I have four conditioned batteries and they register 16.6 on the ST16 from the beginning to now with many flights. Never have obtained the magical 16.8.
