Victron Energy LiNGST Lithium NG Service Tool USB-C ASS032300030

The Victron Energy ASS032300030 LiNGST Lithium NG Service Tool USB-C is a professional diagnostic and commissioning interface designed to provide a direct wired connection between a Windows PC and the M8 service connector on compatible Victron Lithium NG batteries and BMS NG products. It gives trained installers and service personnel access to advanced battery monitoring, data logging, BMS testing, troubleshooting, and commissioning functions.

The ASS032300030 is specifically the USB-C version of the Lithium NG Service Tool. It incorporates a 150 cm (59.1 in) USB cable and a 20 cm (7.9 in) M8 connector lead. The product-variant section and image on page 2 of the manual distinguish this model from the USB-A version, ASS032300010. 

Using the Victron Lithium NG Service Tool application for Windows, technicians can monitor and log Lithium NG battery data, simulate a Lithium NG battery to test BMS functionality, and record data from complete multi-battery Lithium NG systems.

The LiNGST is a tool for commissioning, debugging, in-depth system analysis, and technical assistance during on-site work, particularly where wireless access is unavailable. 

Key Technology

• USB-C Lithium NG Service Interface
  Part number ASS032300030 is the USB-C version of Victron's LiNGST, providing a direct wired interface between a compatible Windows PC and Lithium NG equipment.
