Junsi,
I've been trying to get my 106B+ to work with Logview but keep getting an error message: "COM port can't be opened"

I reinstalled the Logview program and the Junsi USB driver and still the same.
I also tried to register onto Logview for their support but they ask a random question? "beGrlin-G" I have not idea what that is all about.

Please help,
DM

Hi,

My 1010B killed itself while discharging to storage

It was discharging, fan was running and it was not very hot but warm. Then suddenly it showed error: "Input vol err - low voltage".

Now, when I connect to power supply, it first shows correct input voltage (13.xx V) and output voltage (0V). When I connect battery it still shows correct Vi but Vo is shown much too low (should be ~14V). And when I finally connect ballancer port, it first shows Vi=0V for a short time and then the error again: "Input vol err - low voltage".

I made a small video to show this:

Problem with 1010B+ after discharging (to storage level) (0 min 39 sec)


I guess, some "high power part" is broken as it happend on discharge with maximum power. Can anyone tell me which part it is from these symptoms? I can solder and swap parts, but I am not that good at reading circuits

Thanks,
- Oliver

Hello All,

I'm a new owner of an iCharger 106b+, I purchased it to replace my cheap Imax B6 clone because I wanted a quality charger that can deliver what it promises and is very accurate. I have very basic understanding of electronics (from elementary school some decades ago). I tried to search and read back a few dozen pages, but did not find anything related to my question. So I apologize in advance if it's been asked before and if my question sounds very stupid.

I was charging a 2s 2100mAh LiPo pack at 1A in balance charge mode and at some point I saw something on the LCD which scared me: it was showing 8.58V output for main lead. I immediately checked the cell voltages and those were fine around 4.0xV (I don't remember exactly, but they were definitely below 4.2V and as far as I remember slightly below or around 4.1V per cell). I stopped charging. I've never seen higher than 8.4V for main lead on the B6, so seeing 8.58V on the 106b+ surprised me very much.

Is this normal? If yes, how can it be much higher than the sum of individual cell voltages measured on the balance lead?
I checked the calibration with my DMM, balance leads are accurate and main lead was lower by 0.05V. So I guess it wasn't really a calibration issue.


At the moment I'm using a cheap laptop AC adapter (outputs 12V and max 5A) to power the charger. I plan to get a proper power source and am looking at the VOLTCRAFT FSP 1207 fixed voltage laboratory power supply (Synchronised 11 - 15 V/DC, 7 A 105 W). I have the opportunity to get it at decent price and specs look good as far as I can tell (I'm charging my largest 7600mAh packs at 5A max, smaller 2100mAh ones 1A max). Could someone please confirm this power supply will work fine with 106b+.

Thanks for your help in advance and please excuse my noobness and English (not my native language).

This is normal. The charger will let pack voltage go somewhat past max voltage as long as it has control of the cell voltages. The difference between pack voltage and sum ofl cell voltages is voltage drop in charge cables and connectors.

Voltage drop between charger and battery. This is due to wire and connector resistance. If this drop becomes excessive, the charger will terminate with error. To keep the drop to a minimum, use short charge leads, heavy gauge wire (14AWG or better), and good connectors.

Yes it will work but that is not a lot of power. You should allow 20% overhead for efficiency loss. So in theory you should not charge at more then 84W to ensure you don't overdraw the supply. That's pretty low for a charger that can do 250W. I would buy something bigger so you can charge that 7600mah pack at 7.6A.

Thanks a lot for all of your fast responses, much appreciated

The Voltcraft has a 180W 12A version, thought that's stretching my current budget at 1.5x the price of the 7A version. I guess I save some money from elsewhere and buy the 12A version for peace of mind I know both is low for the 106b+, but the charger is a bit overkill for me in this regard because I do not ever want to charge at more than 5A - don't ask why, it's my personal stupid reason Longer charge time for the 7600 batteries is not a problem for me, even the batteries are overkill for my use (after 2 - 2.5 hours crawling they are still around 3.71V per cell).
Thanks again!

Pick up a server power supply and mod it, or, if you don't want to mod it, you can buy one here from several sources already moded.

Hey I'm new to this thread and just upgraded to a 206B. I bought it as part of a package. This is the package: http://www.progressiverc.com/the-ticket-350w-combo.html.

Just curious, did I make a good choice. Right now I fly mostly 3 and 4 cell batteries....................thanks

I bought the 106B / 220 watt package from Progressive and have had it for about 6 months with no issues. I think you made a good choice.

Yeah I've been using mine to get all my batteries to storage charge when I am not using them. I couldn't do that with my old charger. So far I am very happy with the package, looking forward to trying it out in the field.

Hi Guys

I'm currently researching how to setup an external capacity resistance to discharge my lipos faster. If I was to do such a thing, does the icharger tell me how much mAh the external capacity resistance has eaten aswell as what the icharger has eaten up?

What do people use as an external capacity resistance?

Same current goes through both (series), so the charger will display the correct mAh value.
There is a spreadsheet on page one, for resistance calculation.
