Flooded lead-acid and Ni-Cd batteries remain essential for critical DC backup power, but manual inspections cannot provide continuous visibility into battery health. Discover how DFUN BMS monitors voltage, temperature, internal resistance, SOC, SOH, electrolyte level and terminal leakage—helping utilities and industrial operators detect faults early, reduce maintenance workload and improve backup power reliability.

In mission-critical facilities such as airports, data centers, and large campuses, backup power reliability is essential. Managing thousands of batteries in UPS systems has become increasingly complex, and traditional maintenance methods are no longer sufficient.

How remote battery capacity testing and an advanced battery monitoring system (BMS) help substations operate safely in extreme high-altitude environments. Through a real-world project in Tibet, DFUN demonstrates how online battery capacity testing for lead-acid battery banks improves reliability, reduces maintenance costs, and ensures uninterrupted backup power for critical grid operations.

As urban transportation systems continue to modernize, ensuring the reliability of emergency power supply has become a critical safety requirement. In a recent deployment, DFUN proudly delivered a comprehensive Battery Monitoring System (BMS) solution to the Prague Metro system in the Czech Republic

Project OverviewThe Indonesian data center project aims to build a highly efficient, stable, and secure facility for data storage and processing. To ensure uninterrupted power supply, the project utilizes 9,454 units of 12V VRLA Hoppecke batteries. DFUN’s Battery Management System (BMS), renowned fo

In this case study, we highlight the deployment of DFUN’s Battery Monitoring System at the Nabiax Data Center in Spain. Our cutting-edge solution is currently monitoring over 1,700 units of 12V backup batteries, providing Nabiax data center with the tools needed to optimize battery performance and r
