What size batteries are you wanting to charge?

Yes, you can parallel charge with this charger.
You can actually parallel charge with just about any decent charger.... it just makes more sense to do this with a more powerful 20a charger, like many in the iCharger line.

To match you with the proper size charger, we will need to know the cell count, mah, and chemistry of the batteries you are currently using; as WoodCrafter has asked.

Yes, you can definitely parallel charge. Took less than an hour to charge up 6 4000 4S Lipos for my 71 Slick on the I306B

Hi guys. I posted this problem on another forum but a member directed me to here to see if I can get this resolved. As posted on the other forum, I have 3x 2200mah 3s lipo batteries. I have discharged these batteries for storage with a skycharger B6AC+ charger and placed them in the refrigerator few weeks ago. Recently I purchased a used icharger 208b and it works well in charging up my 1S batteries for my 120sr and mcpx. Today I decided to pull out these 2200mah batteries to fly my B400 but when plugged it into the balancer, I initially plugged the balance plug into the balancer and the 208B identified this as 11.1V (3s) and that alternatively blinks with "main port?". I then plugged the deans lead in and I get Vout low. I checked these batteries with one of those handy battery checker that shows the voltage of these batteries and it shows each cell has 3.83-3.84V with 11.4v total for each of the batteries. I plugged these batteries back into the skycharger B6AC+ and it charges the batteries just fine without showing any errors.

The firmware has been updated to latest version and all settings are at default. The watt limit has charge set at auto and discharge at 30W.

Any help is appreciated.

Here is the manual for the 208b incase you dont have it. http://www.progressiverc.com/media/i...B%20Manual.pdf. It does not even list the Vout error you posted.

Hi,

I have one of the first 106B+ from HK, which I like very much. Yesterday I wanted to discharge a bit one of my lipos and when I pushed the start button the screen blinked and a smoke smell came out, immediately a message appeared and the fan started. I disconnected every thing as fast as I could.

Later I did connect it again and everything seemed ok, but when I connect the battery to the output, it shows immediately "Int Tem Over Break Down" and the fan starts.

I opened it to try to find the origin of the smell, but didn't notice anything burnt. Please help me. I don't know what went wrong, or how to fix it.

By the way I'm really glad to see that the thread is alive and the chargers are still for sale, but I would like very much not to have to buy another.

Could you please press STOP for 3 seconds to monitor the voltage of each cell to see if there is any difference between the displayed voltage and measured voltage? If different, please check if the battery balance port again, the wire from balance board to the charger, and the balance board are damaged or some lines are disconnected.

Noise Abaitment

This question is not specific to the iCharger, but that is what I am using, so I thought I would post my question here.

With my iCharger, I am using a server P/S (2U size I believe). The power supply has a high speed noisy fan on it. I'm wondering what has been tried to cut down on the noise of these supplies.
I have tried putting some egg crate foam around it, but didn't help much. I was also thinking about moving it further away, but that would involve longer leads to the charger. How long could I make the leads, it I increase the wire gage?

Any thoughts on making the power supply a little quieter would be appreciated. (anyone unplugged the fan all together?)

Thanks!!

There are threads on server power supplies being used as charger power supplies and in those threads there are post on replacing the fans, installing temperature controlled variable speed ones,using resistors to slow the fans down and such.

Got my 306 last night. I should have gotten one of these instead of my 1010.

volts and amps- input verse output

Question guys. I searched and just could not find what i was looking for and seems to be a fundamental principle I am missing:

if my Junsi 350 Power supply outputs 15volts and 23 amps, how is it that I can charge my 3S batteries on that power supply. Does the 208B step down the input received from the power suplly and then output the needed volts? What happens to that extra voltage? is it dissipated in the form of heat?

Second- if the Junsi350 can only give 15volts then how does it charge a 6S battery that requires much more? Does one set the amps higher so long as not goingover max C rating of the battery?

Sorry guys, I truly searched and googled and searched...

Most chargers including the iChargers have a Buck / Boot circuite which make it possible to charge batteries below or above the input voltage.

Is there a fuse in these chargers in case the user does something stupid?
