Home made Discharger

[B4 Sloth]

I was wondering if it was possible to utilise my orion stick pack discharge board in series to make use of the fact it cuts out at 5.4volts. That way I can wire in a couple of fans- to not only drain my packs but cool them whilst doing so- does that make sense.
Not being a sparky- how could this be done? I thought that if the fans/ and or discharge bulbs were before the discharge board this would work. Am I right?
Hope this thread makes sense- My mrs is sitting next to me absolutely caining me for my geekishness-She didnt know the answer!!!
