a123 or lipo.... and other ?s

[BrianG]

The only bad thing about the lipodaptor is that it stops the charge as soon as it sees the 3.6v/cell peak, which would be the very end of the CC phase of charging. You'll lose whatever the CV stage would put into the battery. It's not much by comparison, but if you're using 1p A123s with fairly low 2.3Ah runtime, it could make a difference...

Personally, I'd do the manual CC mode thing MetalMan suggested. It just involves you to watch it carefully and make quick adjustments quite often. Also, this assumes your charger will let you adjust the charging current on the fly...
