SOLVED - Icharger 106B "vout low"

[daniel..]

Hi there,

I have an icharger 206B that refuses to charge one of my 5S packs ( Turnigy 5000mAh 5S 20C Lipo Pack). When I connect the power and balance leads, it reads "low vout" and if I try to force it to charge it says " BATTERY CHECK, LOW VOLTAGE".

The battery monitor says all cells are equally charged at 3.81V. All other packs charge fine.
Any ideas? Thanks!

Daniel

Quick check: have the battery medic discharge the batteries (just click the discharge button, don't have them discharge all the way) and see if any of them drop in voltage quickly. Just looking for a surface charge. Edit, I see you said you have a battery monitor, I thought you said battery medic. Can you watch your battery monitor while you load the battery for a short period of time?

I don't have experience with the Icharger, but my Eco6-10 died in a similarly stupid way. So, it might just be the charger. They seem to give wrong connection error problems when they die. At least it's defaulting to the safe shutoff in failure.

Thanks for the reply. My battery monitor is the monitor function of the charger. Unfortunately, I cannot charge it because the charger refuses to do so. I am going to redo my powerpole crimps (one does not look so well) to see if it could be this.

Regards.

It can be that, low voltage caused by a resisting contact.

How are you powering the charger? If your power supply is not good enough you will also get similar messages and the charger shuts down.

It sounds to me though, like the problem is on the connection the the battery you are charging. You can get similar problems with flaky jst plugs on the balancing cycles too, causing balance cycles to go haywire.

I have an iCharger 1010+ that gives the same message. I connect the battery in accordance to the
sequence of the manual:

1 - power up iCharger, go to correct charging mode
2 - connect balance leads to iCharger
3 - connect + terminal main power wire to iCharger
4 - connect - terminal main power wire to iCharger

the message 'vout low' occurs between step 3 and 4

So.... check the main power lines ! If I don't follow the manual sequence (step 1-4) I can get
funny messages or the iCharger behaves funny in general.

have you checked that the balance leads all have voltage on them on the charger? I had a lead broken that gave me that message

Thanks everybody!

I remade the anderson power connectors and it worked again.
