    My new battery was not used for nearly 2 years. Purchased the cheapest variable DC power supply and a Multimeter on Amazon and followed settings in video. Once my battery got to 16v (took around 10-15 mins) it was enough for the Godox charger to start charging the battery again . Cheers! (did not need to charge up to 21v as in video - maybe different for you).

    I just dropped my ad400 pro and it wouldn't turn on. I took off the battery, and pressed the battery indicator, and the lights would not turn on, so I figured it was the battery that was bad. My friend has the same light so I borrowed his battery, and the light fires right up. I opened up the battery to do some more troubleshooting. My multimeter definitely shows voltage, so it's not the batteries themselves that are bad. Upon closer inspection, I noticed a resistor/capacitor that was broken. I just called Adorama to see about possibly getting the battery repaired, and was told I was still under warranty and will get a replacement. Thanks for this tutorial even though it didn't help me solve my problem.

    This worked great!! Bought a 30$ power supply and took like 15 min of charging to bring it to 13v. Plugged in the original charger and started charging on its own. Batteries were at 1.5v when i started reviving them. Thanks

    Thank you for your clear explanation. The battery is working again! It is a pity that nowhere in the documentation it is stated that this can happen when the battery is completely empty. I thought the battery was broken. I had already ordered a new one. So now I have a spare battery.

    Thanks for this. I just did my WB26 (AD600pro) battery the same way. It'll only give a single green LED (indicating error) for the first while, but leave it plugged-in, unplug, use the reset pins again after a few minutes, plug back in, wait a bit, and now it's charging too! $30 Amazon special 12v/5A trickle charger I'll be using on my RV after.

    This really worked for me. I watched all the other videos but none could get it revived. I bought a cheap dc charger like the one displayed from Amazon (was like usd 20 bucks) Set it to 16v and 2amp charge. Let it charge less than a min and the red light appeared!

    I have a problem with my AD1200pro battery. She doesn't want to charge. The charging process is not the same as usual, the lights behave differently, which indicates an error. I only used the flash once. The flash with batteries was in its original packaging, in a bag, in a dry place at room temperature. After watching your video, I realized that the problem was that the battery was discharged to zero. is it the same method for AD1200pro as for AD400pro? or should I use other voltage? Also, on the original video, they often push with tweezers on two small holes, which is not on your video. What is it for? Thanks in advance.

    I was going to charge my battery and heard a pop and saw a spark from the charing port before i hooked it up. The charging unit doesnt recognize the battery port any longer, but the battery still has a charge (it powered the unit) im guessing it shorted in some way and is unrecoverable through this method which seems to be more about letting it go too long without a charge?

    • @StephanWahlen
      @StephanWahlen  ปีที่แล้ว

  • @katjunket7305
    @katjunket7305 4 ปีที่แล้ว

    Thanks for the instructions. I actually managed to get 5 out of 6 of our AD600 batteries recharged.
    And everything actually went pretty smoothly.
    As I did that about 2 months ago, I wanted to try again just to document the exact steps.
    Fyi....the batteries I'm testing on are all most full power.
    I checked the voltage on the power supply on the mult-meter and set it to about 6V.
    However, for some reason now, when I try to charge a battery, I notice that the battery will spark a bit and the readings on the power supply spikes to 30V right away.
    I tried this on multiple batteries and the same thing happens.
    I tried connecting my power supply to the multimeter and do confirm that the power is 6V.
    I try to charge the battery again and the same thing happens. The battery sparks a bit and the power supply spikes to 30V. And this seems to happen for any battery I test with.
    I'm gonna run another test to drain a battery first before trying to charge with power supply
    Any idea why this happens? Is it because the batteries are almost fully charged?

    • @katjunket7305
      @katjunket7305 4 ปีที่แล้ว

      Update: I managed to get the battery drained. When I tested it on the multi-meter it still had a charge of about 25.5V. When I attempted to charge it, it also sparked for a quick second. I suspect that batteries that are working and behaving normally will have a decent amount of charge left in them even when the unit says it needs to be recharged.
      Hence, I'm assuming that any batteries that are still "alive" will most likely briefly spark when attempting to charge them with the power supply.
      Someone reached out to me to see if I can re-activate their battery.
      I'll give you an update on whether or not I observe the "sparking" on a "dead" battery.

    Hi @Stephan did you or anyone else come across that the chargers green lights (after been juiced up to 21V) have a rainbow effect. What I mean is that one led is lit and then goes no the next led and at the same time turns the previous one off.
    XOOO, OXOO, OOXO, OOOX, Repeat. X is a green led turned on.
    I don't get the flow of four green leds as I should

    Good tutorial. I followed the steps and got my batt pack voltage up, but the indicator lights do not light up (when disconnected from the charger and "standing alone") and the flash/head unit does not power on.
    Very disappointed with this Godox light.
    Promised the world but does not live up to expectation.
    Like so many, I "stored" the light for about 6-7 weeks and it would not work after that.
    How does one "reset" the BMS? Other tutorial vids did not work for me.
    No batt heat build-up when charging...

      I know nothing about batteries but what I did was I got a 6-12 volt 2 amp charger from home depot. I also bought a multimeter to see what my voltage was on the battery. I opened up the battery and I kept putting the contacts on the charger to the negative and positive contacts on the battery. I kept measuring and when I finally got it to 12 volts I connected the original charger and it worked for me. Hope it helps.

    I don’t get it. What process are you using to recharge it? What are those leads hooked up to that you are touching to the contacts? Are they hooked up to the Godox charger? And if so where did you get the leads to hook up to the Godox charger?

    • @StephanWahlen
      @StephanWahlen  4 ปีที่แล้ว +3

      I am using a bench power supply to recharge the battery.
      The Godox charger won't recognize the battery when the batteries internal BMS (protection circuit) detected that the battery is deep-discharged.
      The bench power supply also allows to recharge the battery more slowly, carefully.
      If none of this makes sense to you, please do not attempt this method. Li-Po batteries can cause a lot of harm if handeled incorrectly.

      While charging? Or while using it? Did it always get hot?
      Anyway, that's not a good sign. It seems the cell chemistry is altered bc. of the deep-discharge. That results in higher inner resistance and therefore more losses/heat when charging/discharging.

    • @StephanWahlen
      @StephanWahlen  3 ปีที่แล้ว

      It's a bench power supply, sometimes also called lab power supply ("lab" as in laboratory).
      I've seen Cheap units as cheap as 30€, 40-50€ is a usual going rate.
      If you're not familiar with, please be warned. These power supplies are not a battery chargers. They don't have safety mechanisms to protect anything, they output exactly what you set them to.
      If you set the wrong output voltage and current, you can destroy your battery, causing bloating, puffing or - worst case - fire and explosion.

      You will need a power supply that is configurable in both current and voltage.
      It is important, that it has the feature to limit the current! Do not use a standard 24V wall-plug!
      Look for "bench power supply" or "lab power supply".
      Those start at ~50$ for the typical entry-level model (up to 30V, up to 5A)
      Turn the two knobs on the front to the most left position (ie 0) and slowly turn up the voltage to 24V afterwards the current to 130ma (0.13A)
