Now I would guess the main reason to do a DIY conversion is you don't have £25,000 plus spare to chuck at a car, so managing to source good value batteries is going to be one of the most important aspects of a build.
So in the UK what are the best value batteries for a ICE conversion to have circa 100 to 150BHP and over 200 NM of torque?
Is it Leaf batteries or are there any others to look out for?
