With the 185-lb payload of the prototype (with the pilot), it is obvious that a battery-operated Beaver is not yet commercially viable. The key to the success of this project is advancement of battery technology. The pace of this advancement is such that McDougall expects to have a commercially viable electric Beaver in service in southwestern British Columbia before the end of 2022.

That’s a couple of trout you can carry. Everybody else on the trip is still walking.

Well, if they replace the LiFePO4 batteries at 135Wh/kg with the widely available Li-Co (commonly known as lithium ion) that currently are 270 Wh/kg, their battery weight is cut roughly in half. Payload would be in the neighborhood of 1185 lbs in addition to the pilot, since the Beaver only holds 6 passengers, this is acceptable.

They were never planning on running the commercial flights with the LiFePO4 batteries, just used them for the test flight.

WARNING: This article contains the phrase "Development and commercialization will likely take three to five years." - which usually translates to "Numbers based on extrapolation from lab experiments an we have no idea of if it's mass producible, what it will cost, what the battery's lifetime will be or if it works under anything but ideal conditions."

Leadership seems pretty solid - "Greenshields (Chairman) and Innolith’s CEO Sergey Buchin are well-aware. Previously, the two men were the chief technology officer and chief operating officer, respectively, of Swiss-battery maker Alevo. That company filed for bankruptcy in 2017"
