Battery system vri BASE LINE

Fully developed and approved – flexibly adaptable for you

With vri BASE LINE, we offer you a standardized product family that is ready for immediate use and can still be customized to your needs. The series is based on a modular design, available in two common form factors (18650 / 21700), and meets the highest performance requirements. The completed certification process saves time, reduces costs, and enables a quick project launch – without additional licensing procedures.

For you, this means: reduced development effort, shorter time to market, and full planning reliability.

The intelligent Battery Management System (BMS) allows for precise control and monitoring – and is designed for second-life use: when the cells are replaced, the BMS can be retained. This supports compliance with growing regulatory and market requirements and contributes to resource conservation and sustainability.

With vri BASE LINE, we offer you a smart battery system for industrial applications that enables a powerful yet cost-effective energy supply for your products.
