The State of Charge Head (SOC head for short) when placed at the end of your battery pack allows for instantaneous measurements of both pack voltage and output amperage. This allows you to determine usage rates and state of charge for your entire battery pack.

The SOC head comes in a variety of sizes and shunting options to match your packs maximum voltage and amperage output requirements. It is important to pick a SOC head that has larger voltage and amperage capabilites than your pack.



Rated Current

Maximum Peak
Current (5seconds)

Low Voltage 125/250V




Low Voltage + Upgraded Shunt




High Voltage 250/500V




High Voltage + Upgraded Shunt




*Maximum Continuous Current is 2/3 of Rated Current

Although a high voltage SOC will work with your system, we recommend chosing the SOC closest to your pack voltage. By picking the voltage closest to your actual pack voltage you will be able to attain higher voltage sampling resolutions during the analog to digital conversion process.
