Yeah I have that one (most likely the same - think I got it at $2 on sale). That would be the one I would carry since it's small. It's useless for current measurements (at least for flashlights - see here), but I would only be measuring voltage anyway on the trip (and it seems fine for voltages). I guess it won't be that heavy to carry for the assurance of being able to measure the cells.
