The 2Q standard harness includes one temperature sensor and this pigtail just plugs into the second sensor input connector.
The 2Q BMS comes with a single temperature sensor as part of the harness but with this harness you can easily upgrade it to 2 temperatures.
Include 6 ft (2M) leads for temperatures and current shunt
We also offer a 4 sensor harness for applications needing 4 temperatures per pack
