DonaldBecker says "The v0.3 MRE appears to have a weakness with reverse voltage protection
(when the battery is connected in reverse, applying -12V to the +12V
circuit).

Specifically unprotected 12V power is supplied to the e-throttle TLE9201
H-bridge chip, several pins of the TLE8888 (BATPA, BATPB) and the main
capacitor. These are not rated for negative voltage."
