Hello, TCE here! Just a quick note that I am aware that the camera framing is tighter than I'd have wanted for a portion of the video. However, I couldn't re-record this, as I didn't want to take the pack apart again, and potentially further degrade it. While it may appear like some of the action is off-camera, all that is there is the connections. I aimed to address this with the diagram of the overall configuration in the video.
Hi, I have the newer version of the Powercore 26800. Where it has a temperature sensor instead of a BP wire. The cells are almost full. Total 15.6v / 4 = 3.9v per series connection. Not giving a discharge. But once plugged in, the battery indicator shows its full. Immediately after unplugging the type c, light goes out and doesnt turn on again.
The 737 has got big firmware reliability problems. Display goes into protection low voltabe or low temp or high temp mode randomly and cant be hard reset. This item needs a recal before they all get returned.
I've had my powerbank in this state fro about a year now, and I've just opened it up to take a look, and I'm getting a reading of 2.81V on one set of batteries and 2.83V on the other, and I don't get any responsiveness from the LED indicator. What would you recommend I try?
That’s a pretty low SOC (state of charge) on those cells. I’d watch the video that you just commented on, but instead of performing it on just one “side” of the cells, you will be performing it on both “sides” (one side at a time). Hopefully that makes sense; if not let me know! Best of luck, and proceed at your own risk. Thanks for watching!
The whole pack needs "balancing", ie each cell needs to hold a certain charge voltage and all cells need to be in a specific range together..if even ine cell is out but a certqin amount, the rest will.not work Its a safetything.
Hmmm, that's not quite true. The cells in parallel "self-balance" to the weakest cell's voltage. No active balancing is needed there. It's only when you get into cells in series with one another. Perhaps I'll make a video to demonstrate further. Thanks for watching!
How i change my power bank IC i have this power bank hi convert ic is not working i buy and change but power bank not working if you know please help me
Hi Mr Engineer, I got a Anker Powercore II 20000, its almost 3-4 years old haha... For somereason its charging, it does the same animation/light/leds to as its Charging, but it doesnt charge - It comes very hot where the BMS board is, and when I press the button to see if there is any lights... It doesn't light up. Any idea?
Note that it wasn't discharged for too long... it was fully charge, and used for a bit, and in the next day I plugged it in for charge. I haven't opened the Battery up yet to check voltages. Might do soon...

I just bought a second one. Both of them can’t be charge after a few months

I have completed these steps and now it’s charging. However not discharging. Both set of cells are at 4.04

loving the channel,thank you.
Hello, I bought an anker powerport 3 mini charger and I have a problem with it. Please help
Hello my anker Power bank 26800 it’s show chagrin but wen remove for charger it’s not working anything
How i change my power bank IC i have this power bank hi convert ic is not working i buy and change but power bank not working if you know please help me
Plug it into itself for 15 seconds!!!
which micro usb c port can be used/replace mine is faulty and become loose

@@OMGitsAFrEaKDuCkseems like a short somewhere on the board. Have you tried checking the ports to see if they are clean?
have the exact same problem. Looks like it's charging, doesn't charge other devices. Any solution?
interesting...but much of what you did was off camera.
