There is a tipping point. Power vs handling compromise. Modified drivers gravitated to 6100 ~ 6500mah and will see a 0.5sec drop off from lap 10 onwards. Why not slap a bigger battery? Lap times will be slower.

After running 23 days of modified, my daughter tells me it feels like 17.5T Blinky. Her fastest lap was a 15.4s whereas the pre-covid Champion time was around 15.9s.

With better battery tech drivers would be lapping 1 second faster.

Never enough power
