IMAX B6 Error
 

"Input Voltage Error" appears shortly after connecting a Nano-Tech 1300mAh 7.4v LiPo. The voltage is set correctly on the charger as I had been using it for the past year with no issues, only recently has it started doing this. Occasionally it will make the error before I connect any battery.

Is it possible the power cord is faulty or not supplying enough power?

thats usually what that means. do you have the leads to try running it off a car battery?

Which kind of input (usually a 12V ACDC adapter you plug on the wall on one end and on the imax on the other end, but there are other types) are you using?

I've had static screw up the B6. Becareful.

I'm not sure if I do or not. I bought this charger second hand from a user on here. I have two kinds alligator clips, one with a Tamiya connector to a + and - alligator clip. Or a round style plug I have never seen before to + and - alligator clip. Also my standard Deans to + and - that goes into the charger.

EDIT: Upon looking at the unknown plug, I see that it is the DC input to + and - alligator clip. I presume this is what you are talking about?


I'm not sure if it is a 12V or not. It doesn't say an voltage on the cord, which I find odd. All it says is "Resistant 60 Celsius CSA 18AWGx3C FT2 105 Celsius" I'm going to find another power supply that I can confirm the voltage of.

guessing you have an imax B6AC?
With the standard B6 you need to hookup a laptop style power supply to it

And yes, try running it direct off a car battery, not totally sure how it works inside but hooking it up to DC current should bypass the rectifier, since that's obviously an option

Yes, the B6AC. Didn't even think to add the AC part

Well, the AC is basically a laptop PSU built into the charger.

I have a B6 non-AC, and I had this error when my old 10A PSU was dying.
Replaced with a modified PC PSU that can supply plenty and it works fine now.

The error basically says that the voltage dropped under 11.0v.
Most of the time, if the PSU can't supply enough current, the voltage will drop to compensate and screw things up.

Sucks, but that probably means that you will need an external PSU for now-on.

If you want to use a PC PSU to test, you just have to put a metal paper clip between the green and a black wire in the motherboard/24P connector. That will start it up.
Yellow is +12v, black is 0v/ground.

If you want to use the PSU long-term, you need to modify it a bit otherwise it will blow.
10ohm, 10W ceramic resistor across the 5v (red wire and black wire) does the trick. You want to fix that solidly to the metal case, because it will become hot otherwise.

If you have one, you can also use an XBOX 360 external PSU (the grey brick).
Kinda the same, blue+red for power-on, yellows are +12v, blacks are 0v/ground.
