6V - 12V ? - Kayak Fishing Adventures on Big Water’s Edge

For you guys running 12 volts, if you want an easy option to control the volts going to your pump, go to Fry's electronics. In the computer fan area you will find a "fan speed control". It costs about $6 and gives you the ability to adjust your voltage from 3vdc- 12vdc using your 12 volt battery (thus allowing you to adjust your pumps flow rate). Its similar to a speed control unit you would find at a hobby shop to control electric motors in cars/ planes etc. This is a whole lot cheaper though.

If you already have a 12 volt setup (battery/ chargers etc) this is a great way to be able to tone your flow down, and save your battery. Not to mention if your battery is running your FF, you can have this "fan speed control" only wired inline with your bait pump, and still run full voltage to your FF.

As far as I understand, your run time is more about the Amp hour rating of the battery, not the volts. So, either way you go (6v or 12v) look for 6ah or above to get good run time on the water. (These batteries can also be found at Fry's. $19.99 for 6v 7ah, $26.99 for 12v 7ah.)

One final trick on a 12 volt setup is to reverse the polarity, which should make a noticeable decrease in pump flow (if you are running 12 volts straight to a 360gph or 500 gph your flow will be too high...
