These EV West PCB boards will simplify the wiring for your BMS system with the Tesla Model S/X battery modules. We have boards available for all 3 revisions. The EV West boards are unique in that they offer an extra layer of protection by having on board trace fuses in case of any cross current events, as well as a much improved connector by replacing the Molex Mini Fit Jr. plug that can be a source of inaccurate readings of the cell voltages, and we combined the thermistor connections into this single connector, making the process easier and less time consuming. We also include the mating connector and flying leads to simplify the installation and improve the accuracy of BMS voltage measurements.
Note: Please make sure to select Battery Revision Type above for proper fitment. If you have any questions about which battery revision you need, please contact sales@evwest.com
