Can I use a lipo battery like you would in a rc plane or car.
They small. I have a 11.1v 1500 mah lipo battery. I used it in my airsoft gun.
The gun when close to 2 day on a charge. The Elite 4x dsi voltage input is 10v to 17v. Current drain is 200ma at 13.5v.
I can get a 14.8 volt 1600mah battery that about 1" x 1 3/8" x 5"
It will only be used to run the Elite 4x dsi on my kayak.
