Please HELP - Charging 2s with Turnigy balancer & Charger 2S-3S

I have this charger:

http://www.hobbyking.com/hobbyking/s...idProduct=7637

I use this charger the last year for my 3s lipos, I never tried 2s. But today I received 2x batteries zippy 350mah 2s and I tried to charge it, the charger show the charging led, looks all ok, but 30 or 40m later I use my voltage meter and the battery show the same voltage! I tried with the other 2s battery and the same problem...

Can you Help me? Its a charger problem?

What voltages are you reading

Fully charged 3s = 12.6v

Fully charged 2s = 8.4v

I've had a few of those for charging at indoor flying. They work fine and even cut off the charge at 4.15 volts per cell. I had one do what your describing, smell it and if it has a burned smell at all then it's the charger. Ya I know!!! Cheap to replace though.

If your checking voltages and expecting a 2S pack to reach a 3S pack volts when fully charged then tacx is correct. LOL

Thank you... maybe a charger problem because Im charging the batteries with a li-ion charger and theyre working and flying fine

Another question:
On this charger can I charge batteries below 500mah using a 3s lipo 2200mah as power suply? Its an ideia to charge on the field...

Can I burn my charger or battery?

Specs show 12 to 15 volts input so should work.
