Cost £2000 for the 2 x 28s3p 60ah A123 packs.
Other stuff bms, charger etc etc and thousands or hours building, testing, research who knows.
The Voltage fooling circuitry is analog and digital. The MCM compares the analog voltage from the oem battery voltage taps with the serial data coming from the IPU IGBT power device. You have to fool both if you want to use a higher voltage system like I am doing.
If you opt for a voltage comparable with the stock system then you don't need to fake lower voltages.
Sadly I don't have the time to answer lots of questions on different forums so all updates will appear on the Insight Central thread.
