Look at my wiring diagram of how they should be connected. Red/Red and black/black glues together.

I'll have to try that..
Two items I use ALL the time are the handy-dandy 10-bulb discharger, and cutoff relays.. I have one for 6 cells (use a pot to adjust cutoff around 5.4V), and one for 4 cells (wired for 3.6V).. they work like a charm.. The relays can look confusing on paper, but they're really great..
I also make car stands out of old hard drives.. tear out the drive unit intact with the platters, bolt the motor side down on a plate with rubber feet as a base, and put rubber feet or foam around the top platter for your car, and you have an ultra-smooth rotating stand.. If you're lucky, you can keep the unit attached to the hard drive base, but some models don't expose the top platter enough..

About glueing the copper plate to the peltier device, what would happen if I did not used thermal bonding. Instead I use normal super glue and I only glue the plate at the corner end of the copper plate.
That would leave the center part of the copper and peltier device clear of glue and so on.
Would that work???
