Key components are:
- 4x a TE LIM contactor (new and original)
- LIM (with MAC address, not tested)
Furthermore some connectors, busbars for these contactors, M5 to 35mm2 lugs and the DC/DC converters (20 pieces) needed for the Voltage Sense Board and some enclosures (some with cutout already). I will provide and open source the files of the Voltage Sense Boards with it so you can have more made at JLC.
The contactors were 280 euro ex VAT. That's also my price for the package.
So basically buy 4 contactors and get the rest for free.
