Review of Solo 416-Li & Solo 417 battery powered backpack sprayers!

Solo Model 416-Li Rechargeable Backpack Sprayer 5.81 gallon tank volume and Solo Model 417 Rechargeable Backpack Sprayer 6.6 gallon tank. (Note now the 417 6.6 gallon tank was replaced with a model 417 with 4.5 gallon tank making the present 416-Li the largest capacity. Both sprayers require no pumping and allow fully automatic spraying with both putting out 36psi on low pressure and 63psi on high pressure. Great for big spraying jobs where time is money and there is no time for manual pumping. The 416-Li with it's lithium battery will run 5.9 hours on low and 3.7 hours on high pressure in between charging. Charges in 5.5 hours. The 417 with it's lead gel battery will run 4.3 hours on low and 2.4 hours on high pressure. Charges in about 8 hours. Both sprayers cannot be overcharged and have a red light when charging and a green light when charging is complete. I recommend Forestry-suppliers.com as the cheapest and best place to purchase these sprayers.
