Haven't looked yet, but from other feedback so far, its probably going to

If it turns out to need a 2S battery, I'll charge that off a proper LiPo
charger/cycler to keep both cells at the same charge state. Not doing
that causes problems with LiPo batteries.

I strongly suspect that ripping a Li-ion phone charger pack apart will
reveal a 5V regulator and a proper balancing charger in ine of the berrte
ones. Not so much in the cheap'n cheerful variety.
