No disrespect or anything Nick, but we are comparing apples to oranges here.
Battery management and maintenance are a huge concern to most on this list, and Corvus are the first manufacturer I have seen that is going after commercial shipping market with a product that is virtually plug and play and by all accounts pretty bullet proof.
100% DoD without damage.. Plus super fast charge and discharge capability.
Their maintenance section is rather amusing:
How to Maintain a Corvus Energy Battery:
DON'T. You will never need to.
But if you feel you have to:
Dust it off every now and again, a shiny battery is a happy battery.
Say nice things when you see it, you dont need a lonely battery.
Add nice stickers that highlight your business. The battery likes to feel at home.
So given the headaches of battery power, it seems like this solution would make a lot of that go away. Plus they base their entire sales pitch on RoI with fuel savings... pays for itself in 2 to 5 years with a lifetime of 10-20 years.
