The Kingston team uses LifeBatt Lithium Ion Phosphate batteries and a “Performance Through Lightweight Solutions” design mentality based on theories by Colin Chapman of Lotus. This translates to an average speed 70 mph and a top speed of 102 mph on the downhills. The weights an estimated 352 lbs of with 220 lbs of that being batteries.

Great information comparing energy density of Lifebatt Lithium Ion Phosphate batteries to gasoline and the efficiency of electric to ICE.

wow, that looks pretty cool. And that chart is pretty interesting, 3.5L of petrol contains the same energy as 100kg of batteries, evs have a long way to go before replacing petrol vehichles.

Hopefully the TTXGP will get more money flowing into battery tech.

huh, just rading a bit on FES, flywheel energy storage, is 130whr/kg max, and charge up in less tha 15min. wonder if we will see some of them eventually
