This is not a power bank, this is a product of a person who does not know what he is doing! Don't do this at home!
The module used to charge the batteries is too weak for this package!
The voltage conversion module is also very weak and heats up to a high temperature at a current above 1A!
Never connect lithium-ion batteries in parallel if their charge is not the same!

I need help please, I built one with the same components except for the lipo batteries but they output nearly the same specs, the batteries are capable of outputting 2350 Ma, 14. 80 volts and 34. 78 watts, but the trouble Im having is that it only works on very short charging cables (less than 1ft) and will not charge through anything longer than that. Can anyone help me out?

this should never be done. I'm sorry but lithium ion batteries aren't like AA's. They only need exposure to air to catch fire. Just watch any video of E-sigs or even cell phones exploding in peoples pockets or while using. (and the cell phone batteries were even commercially made) Someone at home trying this could easily make a mistake and seriously injure themselves.

It may be too late now but I think it would be best to solder the data pins of the USB connector together as this will allow the maximum current to be drawn by the smartphone, around 1. 5A. If you dont it will default in aroun 0. 8A.

What about the high internal resistance of the battery? Does that just result in a lower battery capacity or is it a safety hazard? But hey, you're an electrical engineer and I'm not

This year I created the powerbanks charger using the powerbanks to charge themselves and next month its renewable energy to charge something continuously rating to 5 VDC to 9 VDC

How are u able to charge 6 battery in parallel with tp4056 because the charging module has only 1 amp max output capacity. wouldn't it take forever to charge the battery pack?

At 1: 27 in the video, what is this black point with the 2 red cables? I dismantle my battery pack and I'm trying to understand what are these (I have two of them)
