Hi, i have the same problem as most of the people: Err2!!! with different power supplies!!! so, HobbyKing, what is the cause for this ????

You need at least a 12v 2amp power supply.

Yes at least 12V I used 9V and got voltage drop. I now run on 15V *2A
 Iedutz 12 points
i have 15V at 5A stabilized power ... so, an other answer ???

Tedutz, light guage wire leading to the charger can cause enough voltage drop to cause issues. 18awg or heavier for a 3' lead ought to be adequate, heavier if it's longer.

This is a great, simple little checker/charger. I've been using one almost daily for 5 months now to charge 3s LiPos up to 5200mAh and love it. It's slow charging, but that's my preferred way to charge for extended battery life and no heat issues. It leaves my batteries better balanced than my $60 charger. In fact, for less than the cost of my $60 charger I could have a half dozen of these charging batteries at the same time. I can run it from a simple wall-wart power adapter and my car dash power jack. I say don't change it! Its simplicity and low cost is its beauty. No switches to wear out, no menus to hassle with, just plug it in...simple and reliable. If you want the beeper a little louder you could pop off the top cover and drill a small hole a little left of the display window just above the beeper. I’*ll be buying more of these.

Hi all I'm getting an Er01 message in mine charger. Any sugestions?

I have been using two of these now for about a year and I have to agree they are great little chargers. One of the main plusses for me is that you can leave the battery in the model and charge through the balance lead so I am not disturbing the main power connectors. There is one thing they could do with these days though - a LiFe option. I believe it would just be a slight modification to drop the charge cut off voltage from 4.2 to 3.6 volts. Even if it meant buying a new charger just for LiFe at $8 it isn't exactly going to break the bank!

Hi Harry, Good point about the LiFe option. A simple slide switch on the side would do the trick and probably not add more than $.50 to the price. Cheers, EA!

2 thumbs up!
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.

Do not order these pieces of crap. They fail within 1-2 weeks, and return shipping is nearly (or higher than) what you will be refunded.

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..)
