You are saying that since the internal battery resistance will be halved, the charging current will double. Also, it looks like there is a slight chance that the cells will get off-balance.

It sounds like it'll be easier to get a 5v to 12v voltage booster and feed it from a mobile power unit via usb.

Something like this, perhpas:

I'm not sure which one would be best though
