Maintenance & Balancing

Cell balancing and regular maintenance of your lithium batteries are essential to ensure maximum longevity and stable performance. An unbalanced battery fleet can lose up to 30% of its effective capacity and increase the risk of premature failure.

This sub-category teaches you all the professional maintenance techniques: battery log retrieval and analysis, DC balancing procedures, BMS problem diagnosis, and building solid warranty files.

Retrieving Pylontech logs with Battery View. Our expert guide explains how to install the official Battery View tool, connect via USB-RJ45 cable or RS485 console, and extract critical data: SOC history, individual cell voltages, temperatures, charge/discharge cycles, error codes. These logs are essential for any warranty claim.

Official DC balancing procedure. Adding new LiFePO4 batteries to an existing fleet requires rigorous pre-balancing. Find out why passive BMSs are insufficient and how to perform this critical operation: successive slow full charges at low current (0.05C), cell voltage monitoring, and final balance validation. Without expensive laboratory equipment, but with method.

Also learn how to diagnose the symptoms of an unbalanced fleet: premature shutdowns at high SOC, cell voltage differences >50mV, abnormal heating, recurring BMS alarms. Our troubleshooting guides will point you towards the right solutions.
