Battery or Charger Problems

Hi All

I am new to the Typhoon and I am concerned that I may have a battery problem. Nor am I an electrical engineer! So any help from those of you with far greater experience than me would be great.

I have 3 batteries and after a flight a few days ago whenever I put them in the charger I get the blue flashing error code and a tone. So effectively I am grounded at the moment! Note this is the standard issue charger that comes with the unit.

I have just tested the voltages of the batteries and they are as follows:

Individual Cell Voltages
Battery Number C1 C2 C3 C4
1 3.8 3.79 3.79 3.8
2 4.12 4.12 4.12 4.11
3 4.14 4.13 4.13 4.13

With my rudimentary knowledge as far as I can tell these batteries are fine and its most likely the charger that's at fault?

Can any one confirm that these voltages look fine?

I am waiting for an answer from Yuneec UK but they are not being very responsive at the moment!

Those voltages look fine. I assume the one at 3.8 is after usage.
By your user name, I assume you are a fellow kayaker?

A fully charged cell is 4.2 volts. Storage voltage is about 3.7.

RiverRunner, thanks for that, gives me confidence when dealing with the retailer. Yes the 3.8 is after usage and yes I am a kayaker albeit nothing challengeing just sit on tops on calm rivers!

By way of an update, I went back to my local supplier and after lots of testing there were two issues - a dodgy charger and it appears that the contacts were sensitive to oxidation. So a bit of a rub with the end of a voltage checker and they were fine. I think in due course I am going to invest in a decent charger and adpter (as now sold by yuneec). The charger that comes with the Typhoon H seems a bit shoddy.

But they are cheap to make and barely adequate, therefore fulfilling a requirement to provide "a" charger;)

Your battery cell voltages looked real good.
