Hi,
Im planning to build an xxxl power bank to charge some mobile devices. Once or twice a year we are going on a camping trip with around 6 people. I am not sure if is use the right board category.
Currently, I am harvesting some 18650 cells from notebook batteries which I got from my office.
I think I build a 4s 20p battery pack.
It would be nice if I could charge the power bank very fast: sometimes we have access to a public power socket on the camping ground, so I would like to get as much power into it as possible in a short time. So I could use a 20V 8.5A notebook changer for example.
I also want to add an option to change the powerbank with my existing solar panel (https://de.aliexpress.com/item/Port...stalline-Silicon-Wafer-Camp/32805061069.html)
I think I should use this BMS: https://de.aliexpress.com/item/4-S-...B-BMS-Schutz-Bord-mit-Balance/32837937191.htm
Then I have to set the voltage to the 16.8V with this module: https://de.aliexpress.com/item/1PCS-Electric-Unit-High-quality-C-D-C-CC-CV-Buck-Converter-Step-down-Power-Module/32806874450.html
Or can I use this with that fancy display: https://www.banggood.com/de/MPT-721...ge-Controller-with-LCD-Display-p-1056572.html
