This 16 Liters Lithium powered Backpack Sprayer delivers 1.0 GPM at open flow and has a maximum system pressure of 40 PSI. Equipped with a 2.0AH lithium battery, this sprayer can sprays up to 165 Liters on a single charge. Not only is the pump durable, the tank braves the elements with UV-stabilized material to prevent fading and other sun damage. Adjust the spray gun nozzle to three different spraying modes: stream, cone, and atomized mist, depending on the job.

Unless you have a serious problem with your arms, just get a non-battery Solo backpack sprayer. Have been using mine once a month for more than a decade and still works like new. It just takes an occassional pump as you wander around - what else would you be doing with your spare arm anyway?
