Trolling motor batteries

[SPORTSMAN68]

Got a 112 pound thrust trolling motor---manual said to use 105 ah battery---it requires 3 batteries--so do I need each to be at least 105 ah ?

It is a 36 volt system so three 12 volt batteries wired in series are needed. Unless all three batteries are 105 Ahr as recommended, performance (run time) would be diminished if one or two of them were 80 Ahr respectively. The lesser rated batteries become the weak link in the chain so to speak.

Yes ...all 3 must be same. 105 is the minimum

if they are not deep cycle batteries, doesnt matter how heavy duty you think they are, you will kill them.
