Just received and used it today, it's great but can the pressure be adjusted down? It's very powerful and atomizing the spray so I'm getting drift

Adjust the nozzle or put different nozzle on. Atomizing is preferred for some tree or shrub spraying, but you need to adjust the nozzle. Good pressure is great.

What all brand batteries work in it? Whats the biggest battery compatible?

Takes the same battery as the Ortho Sprayer.

Does anyone else have a problem with having 4 gallons of product but tbe sprayer will only spray 3 gsllons and won't spray the last gallon ?

I have the same issue. I believe it's because the internal pick up tube is too high i also need to see if i can have my harness replaced either way still lasts me about 2 house treatments maybe 3 depending on square footage. I'm actually looking to order a second one as mine is finally a year old. Still works after the abuse of arizona residential services.
