Remember Me Adtasheet Password? Page 9 of 10 First. Aug 11, Has anyone checked what the charged voltage of their batteries are after charging through the usb? I just noticed on the datasheet for the AA transistor they state the collector-emitter saturation voltage is 2v so using 6v of alkaline AA batteries you should get a charge voltage of 4v but i am curious if you only feed 5v what the batteries are charging to? I should analyze dataxheet circuit in the charger to see how they have it connected because this would also lead to inherent problems when using rechargeable batteries Aug 24, I thought you guys might be interested in a different type datasyeet mod I posted.
It lets you charge up to 5 batteries at once.
This has the added benefit of reducing the total charge current to each cell so they last much longer than being slammed at 3C! Please leave comments on the new thread so I can answer them.

When I put a battery in the charger it seems to work just fine. Then the light stays lit after I remove the battery. I remove the AAs and try again with another. Then the light never goes out.
Neither time is the battery so much as warm to the touch. Also, when I use the wall wart, I get nothing. My best guess at this point is my use of the wrong solder.
I’m only hoping that I didn’t fry anything. I found the issue. I was using the wall wart from my Dx6i. May have fried something on the board. Reconnected everything the way it was before I began mucking about, and it doesn’t charge Wondering now if the batteries need to be changed, maybe I lucked out and all is not lost on my little misfit.
Last edited by SCF; Dec 08, at Dec 08, Anybody with input on how to reverse the polarity on the N power jack? Unless anyone has any better ideas, I plan on plugging the wall wart into the wall then plugging the lead into the jack. That should give me what i need to know. Jan 04, Jan 06, I ended up getting this fixed up the right way.
Used a meter to do it right. Jan 09, I just successfully completed this on the charger that came with my parkzone ultra-micro p The charger appears to be exactly the same minus slightly different branding on the front.
I picked this up from frys a while back.
I opted to splice the wires instead of soldering directly to the board since I am not that confident in my soldering skills. I used some heat shrink tubing to avoid shorting anything out.
I found several other mods that prevent you from being able to put AA batteries in, or they require you to leave a single AA battery to power the LED. Jan 14, Can you do this Mod AND modify it to a wall charger as well? I have a cellphone wall charger with an output of just over 5V Quote:. Originally Posted by tmenet.

Two diodes in series was my approach. Cathode stripe goes toward the LED. The diode approach does not change the current profile as they only drop voltage, not limit or change the current.

A resistor changes the current flow and also expends heat or power. Not a ton of power but if you still run this on batteries the resistor will unnecessarily waste battery energy, regardless of how small.
On the second charge cycle this degrades further to ma ratasheet so on. Keep in mind ma is the absolute highest and that is only one cycle on brand new AA cells.

Whether you put a resistor in series or get the right voltage wall supply set your voltage at 4. Do not exceed 4. Reducing the charge cycle time is nice for the impatient souls but you will spend more cash buying Li-Po cells sooner. Remove at battery terminal.
Connect two diodes in series to this wire. Cathodes stripe toward LED. Connect diode Anode to 4th battery positive. Jan 13, Sorry for bumping such an old thread but I thought this might be of interest to some of you out there. I drew a schematic to try and understand how this charger works.
Also I was planing to modify it to accept dayasheet wall wart as it eats batteries! The SOT is a mystery to datasheeg. Its marked “GELF” but google knows nothing about it. Last edited by markusb2; Jul 31, at Picture was removed, uploaded to new host. Return to Coaxial Helicopters.
