Six holders for 8 AA cells each, giving 12V total for each battery pack.
The battery holder have press studs like those on 9V PP3 batteries, and I'm offering a load (haven't counted them) of connectors which fit these. I would prefer them all to go as one lot but if you just want a few of either I could split.
