1s lipo help?

[Asotktl]

I have recently recieved an AC680 charger and am trying to charge 1s lipo's. I'm sorry if this has been covered but I have not had any luck finding any info anywhere. The charger does not seem to stop. I am charging a turnigy 300mah battery, shouldn't this battery only charge to 3.7v?

When I got your pm I wasn't sure what you were asking. On most chargers they go a ways past the 3.7 volts. Does it have something on the display that shows how close it is to charged? Like a bar indicator or a % readout? Also if there is an adjustment to the charging amp rate make sure it is set under the max charging rate for each battery. Hope that helps.

it should peak at 4.2v, 3.7 is the nominal voltage, peaked voltage on any battery is usualy higher then speced voltage.

It only shows the voltage, the manual doesnt explain anything very well. I stopped the charging at about 4.15v so maybe the charger will automatically stop at 4.2? I think I will play with this outside. The display does show charged capacity with 5 digits, maybe thats mah charged to the cell?
Thanks for the help
