Kayak Battery

Recommended Posts

A mate has bought a water snake motor for his kayak from that large fishing/camping store. 

He is now considering battery size and he believes that the amps draw by this motor he needs a big battery. He is talking about something with the dimensions and weight of a car battery. 

Is this the size battery that you kayak blokes use or should he be considering something else in size and weight that will give him enough power.

I used to run an electric on a 16 foot canoe with a quality 35 amp deep cycle battery. It would be good for 4 - 5 hours cruising up river between snags.

It really comes down to how long and how fast you want to run the motor.

You could get 2x 35 amp hour batteries for the price of a 60 ah full size battery and they would weigh less. use one till it's flat approx. 3 hours use then switch to 2nd battery for another 3 hours. and nobody is going to run an electric motor more than 6 hours a day. Easily stored handled and charged.

If your budget allows, get a FVP lithium 50 a.hr batt. Runs my 24 lb on a 14 foot yak for 8 hrs on full noise. Well worth the $. Weighs less than a 7.5 ahr wet cell. You can run them down to 4v without any issues. Ill never go back
