Does anyone know of a multi-cell / intelligent NiMh ( NiMH only would
be ok) charger that would take a minimum of 1 to 4 cells (not in pairs
as some torches and the like have 3 cells) and with either 100mA
charge option for AAA's or user setable down that low please?

There's a decision tree of sorts, here.

It's a target rich environment, in terms of charging
and charge termination methods.

Yeah, thanks for that Paul.

Most charger manufacturers, they hate BOM cost, and
the odds of them putting thermistors in places they're
supposed to, is just about zero.

Yeah, I've read that elsewhere and judging how hot some of the cells
*have* become whilst charging seems to prove the thought. ;-(
