Default Rechargeable Zinc-Air battery moves closer to commercialization

By comparison, the Gen 2 FES battery has 14 cells, each of 2.1 kWh, or
29.4 kWh for the standard 14 cell pack, so an hPh Shark (dual packs
carried has just less than 60kWh of energy onboard, or 1.6 US gallons of
avgas equivalent.


I think FES battery has 14 cells at 41 Ah per cell. With 58 Volts you get the 2,1 kWh number (per battery back, and with some internal power loss). Two batteries and you end up 4,2 kWh of energy which gives you advertized hour flight duration with minimal power (4-5kW).
