Ann: SOR Battery Ink Exceeds 4V From Moisture in Air, page-117

Caution mate... you're talking about BIG current take-off in these machines (I've worked in mines too). Not even the directors of SOR are mentioning traction-level power. They see the market as being in ultra-low power IoT, skin patches, heart-rate monitors, etc. Their direction (for the present, anyway) seems to be toward miniaturising size, weight, power requirements of load applications, etc. Blasting, drilling or hauling equipment is a different story. Maybe a LONG way into the future, but certainly not this side of the horizon...
