Wrapping up the Kayak Project... Fish finder wiring Question - Kayak Fishing Adventures on Big Water’s Edge

Thanks for all the advice everyone. Looks the FF pulls 1.1 Amps MAX. Not sure what it averages.. Seems pretty high. I agree the 7 AMP battery does seem a little low for this in conjunction with the Livewell Pump... I purchased all the electrical components i needed to install everything. The FF is all set up in the kayak, just the power wiring needs to be done.

Hmm i didn't know that..

That would mean i'd get 4 Amp Hours out of a charge

I'll have to check and see if they have a batter this size with a higher amperage

Where did you find the amp draw? The lowrance spec sheet for the Elit 5 and the mark 5 units is 0.25amps>

Everything get complicated with research. People will run there 12volt battery down to 11 volts, charge it up and run it the next day. Will it work....yes...will it degrade you battery and shorten the lifespan considerably....yes.
I just come from the camp..."if you are going to do something...do it right" the first time, (if you can).
Your bait tank pump should have the amp hour draw as well written on it. Do the math, stick around 60% draw and you will be fine for years to come.
