The cells I ordered are 3300mAh NiMh...
They are tack welding the tabs for me as well in pairs so all I have to do is drop em in. I wire4d up the smartcharger I have to my cube n that will work out just fine. This charger has a very populated circuit board, no doubt computerized.. looks way too advanced except the standard transformer and rectifiers, standard entrance power source although with regulators before the PCB. I'm impressed. I had this thing in my closet for years, never used it.. actually never knew I had it till now.
Problem solved! Always good to work these things out with others.
