    Thanks John!
    This is really useful information, and you've taken the time to show all the steps.
    I've just returned to flying RC Helicopters and multirotors after a break of about 6 years, and to my surprise a lot of the LiPo batteries I'd kept in the fridge at storage charge were still within 5% of their original capacity. However, with 3 microhelis, 2 quadrotors, and a pair of 450 scale helicopters and room to fly them at my house, the batteries have quickly had dozens of cycles and are now being retired.
    A shipment of new batteries arrived, and in the time I hadn't been flying HV LiPo become more common, and I have accidentally found myself with a number of extremely affordable HV LiPos, but my Junsi iCharger 106b+ pre-dates HV LiPo and will only go to 4.30V
    Imagine my surprise to discover that the iCharger has been cloned by everybody, and that there's now Open Source firmware for it.
    Thank for the video. I've subscribed because I think you do some very interesting stuff.

    Hi John III, thanks for the very explanatory video, I loved it, and I also updated my original Imax B6 which also worked very well. I also made updates for several of my friends who also liked it, only one didn't like the update and I need you: Can this update be reverted, do you know if it can? Do you know how to reverse this? Thanks in advance for any response...

      I am not 100% sure but I think it should work. I cant provide any specifc steps, I have never worked with the C341 programmer. But you can try to connect the wires the correct way and see if AVR dude can flash your charger. Maybe there is already some documentation on this on the internet aswell.

    Hi!
    Thanks a lot for sharing this video, you know, since some weeks ago I'm loosing my comfidence in my charger calibration and more than flash it with a Cheali firmware I was looking for some steps for with comfidence reading the existent firmware on my chargers (I have 2 identical, GT Power X-Charger B606). This, just because some chargers has on it a 'once time calibration option' and I want to check this on mine having a copy of the firmware of the mcu of my charger.
    I didn't read anything yet, but just watching your vid can solve 2 questions that I have previously, 1st how to identify the mcu without desolder the ide connector of the screen (if I didn't watch you doing that probably I didn't dare it on my own charger :V ), 2nd, how to identify just what connector (the isp connector) is the one to start on (if exist even) without check on the cheali github page.
    Thanks again your vid is very explanatory and your advices are great! regards from chile,

  • @lebanrifordrndohling
    @lebanrifordrndohling 9 місяців тому

    I have a sky rc imax b6 version 1 and the voltage calibration is off. I did the calibration by pressing the Dec and enter key simultaneously and powering on the device. I connected a 3.7v battery and checked it's voltage with a multimeter and accordingly calibrated the charger. But the problem is i had to set to +20 and still the calibration is off by around -0.07 volts. Do you have any idea on how to fix this or do i need to reinstall the firmware? Will this upgrade also work?

    • @johniii5776
      @johniii5776  9 місяців тому

      Hard to tell the problem based on your description. The firmware upgrade might help, but if the charger is broken or you do the calibration in the wrong way, it won't. Also, i am not sure what the calibration process for the original charger firmware looks like. It might work differently. Anyways, here are my thoughts: Did you use a battery with enough cells for calibration? I think you need at least 3 cells to calibrate all measurement circuits. I also can imagine, you may have calibrated the wrong cells. Cell number 1 in a lipo pack is the two first black wire pairs on the balance lead and cell number [max] is the red and black lead. You may have interpreted the enumeration the other way which would lead to wrong calibration. Follow the calibration part of the video closely and make sure you calibrate the right cell number on the charger for the right cell in the battery. I hope this helps!
      Edit. I see now, you calibrated using only one cell. In that case, I do not see why the calibration should not work. If you calibrate till the displayed voltage on the charger matches the displayed voltage on the multimeter then the calibration should have worked fine.

    hey john, I was wondering if we could get in contact about your 3D printed rc cars steering.
    how did you make sure the joints where fluid and smooth?
    what recommendations do you have in the case that I cant use bearings/bushings?
    thanks for helping bro

    • @johniii5776
      @johniii5776  2 роки тому

      Hi thanks for showing interest in my projects! I the trick is to use low layer heights (I use 0.15mm for the car). For connections between joints i like to use wire about 0.6-0.8mm thick. I design holes in the parts and connect the 2 moving parts with the wire (slide wire through the holes and bend the 2 ends so it cant slide out). It is very smooth, easy to assamble and has quite good tolerances. Direct connections between 3d printed parts without using wire or screws or something else will have friction, worse tolerances and be more fragile. I recommend the wire trick it works really well. Also I use 8mm×5mm×2.5mm ball bearings for the wheels. I design a 8mm hole where the bearings can be pressed into. The wheels have a 5mm lug on them and can be pressed inside the bearing itself. I can do an update video about the car, there are quite a few changes and it works really well by now. I may have time im the following weeks but time is very scarce at the moment :) Again, thanks for your interest and have a nice day!

      My meter has an option for 400mA and 10A I always use the correct fuse. If your meter only has a 300ma option there is no reason to put a bigger one in it. You can damage your meter. You need a meter that has a bigger current meter in it.

      You know, probably that charger is not listed on the ones that support this modification. This because the cheali firmware is for that generic kind of '4 button lipo chargers', idk if you know it but they are like a big family of chinese chargers, all very similar among them. I think to get confirmation you can visit the cheali page.
