N/A - this device stores no energy. Its published '42-60V' is an OPERATING VOLTAGE WINDOW for the 48 V-class battery clusters it links, not a battery nominal voltage.

| note |
SAFETY-CRITICAL GAP: Dyness publishes NO current or power rating for the LV-Link A on its product page. Do not assume it can carry the summed current of four battery clusters. The datasheet PDF is robots-blocked and was not fetched.
