I just purchased a used bait tank(20gal Creekbank) it currently has a short wire with battery post clips. In order for me to clip to battery my tank needs to be in back of boat, I dont have room. If I romove clips and wire on a 12 volt cig. lighter adaptor, will this work. I have a 24v system for trolling motor 12v for cranking and all other acc. will running bait tank off of 12 v affect my fish electronics.
Should work fine - the pumps pull around 3-4 Amps. Just make sure your cig lighter outlet is fused. Is this outlet tied to your cranking battery? A long day and night in the water can pull that battery way down and you might not be able to crank the motor. Might consider a group 26 or so sized battery for the tank pump.
You may or may not get sme interference on your electronics from the bait tank pump. Just have to see.
