You can get motorbike batteries, or batteries for those ride-on lawnmowers. You would need to charge a small battery every day though.

wheelchair batteries come in various sizes i use 20ah ones compact and not to heavy last between 1 to 1.5 days have 3 of them and rotate so always have a charged one on van find a wheelchair company near you they often have secondhand ones
