I'd ask Mark if he can make a 4-cell version for the Sting series, or make one yourself from a plastic 4-cell AAA battery holder.

Thanks, Dave. I did write to Mark, and he replied promptly that he does not have any Sting Series battery packs, but graciously offered to rebuild any which are sent to him. So I'm hunting for either new ones or a 4-AA holder that can be converted into a Sting Series pack.

Meanwhile, I stopped at Batteries Plus today and bought 4 NiCad AA flat-end cells, 1100 mAH for only $1.29 each. Sweet.
