These guys using lifepo4 don't. See the "step by step lithium conversion thread". They have long graduated past the Odyssey-powered chairs.
Their application actually discourages using large prismatics, and favors the much higher-rate high-capacity cylindricals. Roboteq controllers, high-tech motors, wheels, powder-coated custom frames, Hyperion chargers - you name it - non-commercial site with nothing for sale.
Burgerman provides this all on his own to basically show the sorry-ass state of affairs when it comes to wheelchair tech - stuck at the turn of the last century for the most part.
I'd call these guys "msv" or medium speed vehicles now, although Burgerman's racing chair does have functional wheelie bars.
