This is what I was wondering. Very cool.

It'd sure be cool if the 206B could be modified so that it worked like the 306B. Something like 600W @ input voltage 23V (300W @ input voltage 12V)

That would make it a serious bang for the buck.

Thanks for the education Kgfly.

I'm toying with going to 24V for input power. Trying to find any reason I can to justify it.

(by the way....I added the underlineing to the quote. Let me know if I should remove it since it looks like Kgfly is saying it. I just wanted to emphasize the part that answered my questions)

Note that the losses in the charger when charging are not huge as it is around 90% efficient. Still, going to a 24V supply would be a good idea if you think you might need to go to higher power setups in the future.

The 206B works exactly like the 306B in the sense that it delivers half its rated output at half the input voltage required for its full rated output. That is, it requires 17V to deliver 350W and from 8.5V will deliver 175W output.

The components in the 206B are not rated for higher power throughput. If you want more power you have to upgrade to a 306B

Are the resolutions for the several problems secret?

Or wehat ist the reason for that?
I don't see any GOOD reason for that.

Hello Volker,

We are really sorry to cause you confusion.

Generally, we choose PM to answer the question for it's related with the private information about our customers, we need their contact way to offer some specific information for them, or we need communicate with distributors for them, which we think is not necessary to talk publically. On the other hand, sometimes it's really related with some secrets about our products.

Besides, all information will be public if it's useful for our all customer.

Your understanding and cooperation will be appreciated.

Sincerely
Junsi

I upgraded my two chargers 1010b+, One of them was the same as described above.

How to fix this?

Best regards
Happy New Year!

Hello Zulan,

Sorry to cause you trouble.

Please check if you have installed USB driver and iCharger upgrader. If done, please press STOP and electrify the charger, and then connect PC with our original USB cable not your other USB cable to upgrade again.

Regards,
Junsi

Hi

I have send a PM to you...

Thanks Junsi

Junsi, even for very small small things you send PM and do not provide the solution in the forum then what is the use of this forum ?

My issue of error with 2S Lipo is still not resolved and I am not ready to send it to you because that is expensive affair.

I tried to order one iCharger 3010B from your site and mentioned comments to charge me with a sample price, I am waiting to hear on that.

Please note pin #34 of the PLC 44 microcontroller is connected with pin #1 of the AT26DF161 (16 MBit Data Flash), which can be found under the LCD module (TC1602A-15).

I should be able to cycle single cells, and then charge a 3S pack in between without having to re-enter any settings when going back to cycling. I had to redo some cycling because I didn't notice that lower voltage setting had changed from 2.7 to 3.0V after visiting another mode and I "storage charged" a LiFe cell to 3.85V when Li type had changed from LiFe to LiPo.

I like to remind about this. When doing cycling, it's a pain to have to go through both charge mode and discharge mode to set/check the currents used in cycle mode. In general, voltages, current and subtype (LiIon/LiPo/LiFe) should be settable and stored for each mode.

I think it should be possible to post the pure technical information (without any private information) public here in the forum in most cases.

anyway I think it would be helpful because I think that not anyone who has the same problem as a poster here will send you a PM.
They just se a message, see "private answer" ... and leave.

Can anyone help? I have a new 208B, and am trying to use balance board to parallel charge 2 2200 3 cell lipos. When plugging 2nd batt in to middle slot it sparks and wires get hot. Why is this happening?

john

You are connecting the balance connectors in series when moving laterally across the board, not parallel. And you are likely in parallel with the main leads.

Look at this picture. It shows how you hook up packs in parallel using the standard board.

http://www.rcgroups.com/forums/attac...mentid=2969084

You may have burnt up some traces on the board. You aren't the first to do this, and probably not the last.

Wow, so I can't balance my packs using this board? If I gang the balance leads in parallel it won't individually balance each cell, right?

john

Isn't this what we should be using for parallel balancing? or somthing like it? (you have to pick the correct number of cells of course....this one is a 4s version)

8 bucks or something like that. Can't beat it.

The adapter boards with multiple connectors that I have are all for series charging multiple packs. Peel the foam tape off the back of the board, and solder some small wire in place of any burned up traces. Best to check pin-to-pin continuity with an ohm meter too. Progressive RC also has a selection of cables/adapters for parallel charging. Somewhere Julez has a good write up on parrallel vs. series charging (find with a search).

Instead of a snakes nest, why not use this to keep things all neat and tidy, 2S-6S.

Several harnesses, or the Paraboard, they both work, I've got 'em, but the Paraboard is my go to product for parallel charging.
