You have been getting good advice from several on the group. As a point
of
reference, I took a canoe trip in a cave in Belize. There were no motors,
but the light was supplied by a simple car battery driving a standard
automotive headlamp. The battery was sitting just forward of center in
the
canoe, with no box or mountings.
While I'm not advocating such an arrangement used in the cave, a typical
marine type battery might serve you well, depending upon the current
requirement of the motor. With relatively low current, a standard car
battery might even get the job done.
