I'm currently running a Fluidyne radiator with Flex-A-Lite fans and I'm just running them off where the stock fans plugged in and they just don't seem to be pushing enough air, is it possible for me to run them straight off the battery? I already have them ran off a switch.

Depending on the switch you use, it's likely too much amperage for them.
It could be suffering from a voltage drop thru that switch.
Why not wire it with that switch & use a couple of relays to run the fans.
Get some 30 amp spec relays, fuse it off the battery & wire it up.
Google bosch relay wiring
Or even bosch relay wiring for cooling fans.
Tons of info out there for this basic mod.

I think it may be the switch, it does get very hot which is what worries me as well.

I wired both my fans(eBay) to the factory plug, use the stock fan switch, and sealed my fmic and radiator. I used to run very hot at around 210 degrees average and now I'm running between 185-195 daily driving.

I need to buy a new cooling fan switch and cooling fan relay, maybe I'll just do that and say away with the flip switch thing. I'm just afraid I'm gonna be blowing fuses etc.

I haven't blown a fuse yet. I say try it out. Most of the time I don't need the fans on.
