The diode approach does not change the current profile as they only drop voltage, not limit or change the current. I ended up getting this fixed up the right datashewt. I performed this modification and I’m having some very unusual results.
Jan 14, When I put a battery in the charger it seems to work just fine. Cathode stripe goes toward the LED. Page 9 of 10 First. catasheet
First, up front, I did not use rosin core solder. The charger appears to be exactly the same minus slightly different branding on the front. I remove the AAs and try again with another. Connect two diodes in series to this wire.
Qualcomm desktop charger modification. Diode Mod and Battery Profile I picked up an MCX last week and thought it was silly to keep expending batteries so I reverse engineered the charger, came up with a solution then looked to see what others had done.

Sorry for bumping such an old thread but I thought this might be of interest to some of you out there. Dec 07, I used some heat shrink tubing to avoid shorting anything out. This has the added benefit of reducing the total charge current to each cell so they last much longer than being slammed at 3C! I bookmarked it this time.
Jun 21, I drew a schematic to try and understand how this charger works. I was using the wall wart from my Dx6i. My best guess at this point is my use of the wrong solder. I picked this up from frys a while back.

The SOT is a mystery to me. I’m only hoping that I didn’t fry anything. I found several other mods that prevent you a92a being able to put AA batteries in, or they require you to leave a single AA battery to power the LED. Also I was dataasheet to modify it to accept a wall wart as it eats batteries! Is this the battery you are looking for? A resistor changes the current flow and also expends heat or power.
Two diodes in series was my approach. Oct 06, I just successfully completed this on the charger that came with my parkzone ultra-micro p Originally Posted by tmenet. Images View all Images in thread.
Whether you datashwet a resistor in series or get the right voltage wall supply set your voltage at 4. May have fried something on the board. Help with qualcomm charger modification!
Aug 28, Can you do this Mod AND modify it to a wall charger as datsaheet Picture was removed, uploaded to new host. Please leave comments on the new thread dahasheet I can answer them. Also, when I use the wall wart, I get nothing. Do not exceed 4. Not a ton of power but if you still run this on batteries the resistor a928w unnecessarily waste battery energy, regardless of how small.
I should analyze the 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, Reducing the charge cycle time is nice for the impatient souls but you will spend more cash buying Li-Po cells sooner.
