12v step down module? - Kayak Fishing Adventures on Big Water’s Edge

Raskal,

The type of device you have suggested will work fine allowing your main dual battery system all to be at 12-volts. This is very convenient for recharging the parallel battery system. Just be sure that the amperage your bilge-pump / bait-pump draws at 7-volts does not exceed the 3A limit of the DC/DC converter. The converter itself will not consume unacceptable excess power and is totally sealed. All of this is of course assuming you wire things correctly. Go for it!

BTW...the resistor suggested by bus_kid will only work if the resistance load of your bait pump is the same as the resistance of the wiper motors of an air-cooled Volkswagen of some vintage.
