Thanks Russ,
Wanted to confirm what I thought was the case and to know that the 12volt model Power Pulse was the correct one to buy. I bought 2 to use 1 with each drawer of 3 8d batteries If the batteries were in "Series" then I would have needed the 36 volt unit instead of the 12 volt, which can be used for 3 batteries in "paralell".
