Doug's un-law says that I doubt there will identical
resistance. What if one charger is in constant current
phase while the other is in constant voltage phase?

These chargers are finicky. I tried adding some shottky
diodes to the wire on the AC/DC adapter and feeding that
into wearable (to charge and run at the same time). The
charger would not run. It did that 'flashing red light
warning thing'.

I am not an electrician nor an EE, but I still doubt
that you can hook two of these up in series, at least
not with some additional circuitry, and that 1A adapter
does not have enough current to charge 4 batteries. I
wonder about one 15v 6A adapter though, but that would
likely be large and expensive.

Rick said he bought a dozen of them though for cheap
on ebay though, so go ahead and try.

Eric, if your SBC need 5v and you have two of them,
can you hook two SBCs in series and feed them 10v?
