We would like to thank Micron-20 for providing us these PCB's for our discharge circuits. Micron-20 (https://www.micron20.com/en) is the most popular PCB manufacturer in Bulgaria. These circuits play one of the many safety precaution roles, since they discharge the capacitor of the car's inverter. That way, the voltage "outside" of the battery packs drops to less than 60 Volts within 5 seconds if needed. Thank you once again Micron-20!
