Eric,

I think that is probably a typo mistake, the voltage range and capacity is typical for 3000-3500 mAh li-ion cell.
It's a bit awkward to drill down to it, so here's a short cut. Go to this page:
https://jonkersailplanes.co.za/res-system/

Then scroll to the section with this:


Battery specification

Battery type EMECTRIC 96-4 400V
Battery configuration 96S4P LiFePo
Battery Voltage 270V-400V
Capacity per battery 4.7kWh
Battery Weight: 22kg (48.5 lbs)
