Hi
Hope you are doing so good.
I have Neje BL 3000
It was working so great, untill i did not use it for around 4 months.
When i recently charged it for 2 to 3 hours, it turns on momentarily when on battery power, and then turns off.
Then, as i connect it to power adapter, it turns on and off repeatedly.
I disconnected all connections from the main board and it still doesnt work. As i try to connect it to bluetooth app it connects momentarily sometimes but fails to proceed further, and disconnects and restarts.
Battery is not swollen.
I tried another battery, 3000mAH instead of 6000mAH, and both batteries charge good to 4.2 Volts, still it doesnt boot.
Please see videos.
This is the photo of mainboard, nothing appears burnt:
If i disconnect the thermister on battery from the main board, it gives error e05, that means the board knows it has to read the thermister.
Kindly help…
