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.

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

Note: On Rev A modules the cell wires are soldered to the factory BMS boards, so if you didn't purchase your modules from EV West, and you have Rev A modules, you will need to purchase JST connectors and solder these onto the factory BMS wires. For the mating connector that you need for our PCB board, see below.
