You could fairly trivially swap the battery for lithium ion with a usb-c charging circuit[1]. You can get li-ion batteries in almost any shape and size so surely you can find something to replace the old battery.

- bruce343434 5y agoI'm not sure, but I wouldn't order lithium ion batteries from ali express. They are too volatile and ali express products are often simply too shoddy to risk it.
- johnwalkr 5y agoI wouldn’t either but I’m comfortable with charging circuits from there. I also use cells with overcurrent protection built in.
