the battery you are tring to charge is probbably dead or too discharged.. this charger seems to throw an error when the voltage is to low on the battery you are tring to charge.. try with another charger till voltage raises and then plug it into your charger and it should work..
thanks for your answer, but i don't think so, because tha batteries (3s) tryed to charge, are brand new, and the cells was on 3.9V each. In fact the other chargers was done. May be it defect on the 3s socket. In this afternoon i'll try with 2s and 4s batteries just to make all tests. I'll write the results here to share my experience. Without a troubleshooting list we have to broke brain only! :)
if battery 1350mAh 3s 30C and there have XT60 discharge plug then can I charged my battery by this Charger? have I took any extra converting plug and Adapter? please tell me as soon as possible, I am waiting for feedback.
Not a good charger. My charger is not charging my LiPo's anymore. It doesn't come with any manual or any review and it is giving errors that are totally unknown like "Er0","Er2". For warranty it costs very much than the charger cost.

Excellent charger, very fast and accurate. Robust metal housing. The maximum charge is 4.20 V per cell saves the batteries. I recommend! POL88/Sailor NAVIGA /

Excellent charger! Kind of like the CopterX charger but better.
1) End voltage from charger 3s 750mah: 4.20, 4.19, 4.19
2) Charger beeps when battery at full charge
3) Can use this as cell checker at the field
Very handy item. Get warm just like most basic chargers, that's fine. Does not overcharge or undercharge, which most other similar chargers have (CopterX, ESky..)
