Changing charging voltage (4.4v)?

Hi folks, I recently got the HG AIO v2 and the NVME board. I added the 10000mah battery from Aliexpress, it looks like this battery is supposed to be topped up by 4.4v instead of a normal 4.2v. I do see this option in the axp22x spec, but is it possible to apply in our current kernel? I’m using @Rex ‘s TwisterOS image and everything is up to date. Thanks!

This is not only related to AIO or HG boards, but a general issue that happens when you want to use high capacity batteries (having a higher charging voltage in general), even some 18650s do that too.

The AXP228 can only charge to a maximum of 4.2v.
