Viability of using a Tesla 5.3 kWh battery module

It’s about ten pounds (20%) heavier than the existing 4 kWh battery and has about ~32% more capacity.

Has anybody looked into using one of these?

The Tesla battery modules are about 25 volts nominal if my memory serves me correct. For the X4 we need around 45 volts and for the sp140 we need roughly 85v. Sadly the voltage is low enough that it’s simply not usable for our application.

There is a chance that you could modify the X4 for improved thrust and and efficiency, put it on a trike, and run two of these battery modules in series.
