Never used them. I remember people writing about that, so search the forum. I'd imagine it's like with everything - there are god products, but also a few bad ones. All depends on quality of the cells, which you can't easily judge for such batteries. For very bad ones, you may see "battery...

I never disassembled one, but if I'd design such a charger, I'd keep the USB circuit separate from high power output. The only common part would be the transformer, with separate secondary winding. It is easy to check the voltage with multimeter. You do not need to disconnect. Actually you...

It's all good as long as they will get charged now. If any diodes are blinking, then the battery wasn't damaged yet. This is how the marking works at least - 0% does not mean it has no ability to discharge anymore, it means more discharge would damage the cells. We keep batteries in storage at...

These should be enough to give you understanding of the situation; note I linked to specific answers I gave in these threads: https://phantompilots.com/threads/battery-hibernation.151101/#post-1526916...

You want to solder P3 compass board on P4 leg board? If there was any way for you to do this by yourself, you wouldn't have to ask. What you should have done is take the damaged leg (or the whole P4) to electronics repair shop in your area. They would solder the broken connections well enough...

Can't remember how the GPS is normally shielded in Ph2, but in Ph3 there is a copper foil sticker under it. Copper tape is relatively cheap, you may consider it as a solution. Better conductivity than aluminum, and there are tapes with thicker metal than the kitchen foil.

For sarcasm - you can judge that yourself, these other posts are public. Though the situation suggests I was not sarcastic enough. Anyway, the answer: 1. Try trickle charging for a day, that's the only possible non-invasive recovery 2. Open and measure then charge the cells directly using LiPo...

Looks like I failed to convey what I wanted to convey in my answer. Try reading this: https://cs.franklin.edu/~ansaria/internet.how.to.ask.smart.questions.html It explains the issue in a very short and to-the-point form. Show what you've done. Show what you've learned.

If you tried everything, then I guess it's the end. We can't help you beyond everything.

Also more flight restrictions and more discrete spying, ability to lock your drone remotely, and DJIs DroneID broadcasting without your consent. Because the new firmware implements protections and changes for benefit of the manufacturer, and not for the user. It will often lock your drone...

> help please? help please, I don't know what to do I think every instruction mentions this problem. I even updated mine to make it more clear: https://github.com/quaddama9e/dji-technical-stuff/blob/main/davinci-manual-flash-firmware-in-gl300-rc.md#re-flashing-bootloader For the future, if the...

You will find many threads about that already on the forum. They typically point to here: https://phantompilots.com/threads/need-advice-on-firmware.118813/#post-1217799

You have telemetry so your FC is working. You have the video so your gimbal+camera are working. So it would seem you only have trouble with 2 things: * Battery communication * IMU calibration For battery - use multimeter to check whether the signal reaches FC. @Oso already provided you with...

By plugging the cable reverted you might've fried every chip on the board. Though you likely only fried one, the one which got 12V instead of control signal (dji-firmware-tools wiki suggests this board gets 12V in). No control input would withstand that voltage. > i measured the ohm of the...

6 years! There should be some kind of record board for digging the oldest posts. Nothing really surprising. The battery board does not have boots circuit, and voltage at fully charged single not-HV LiPo cell is 4.2V. Looking at older posts in this thread: * If your 3S (ie Phantom 2/Phantom...
