Li-Ion Battery Pack 25.2 V & 50.4 V — BXL7630H / BXLE330H

Power for machines that don't get to stop.

25.2 V and 50.4 V, 680 to 983 Wh by cell variant — with protection that survives its own failure.

Uptime, engineered from the cell up.

Three-stage protection with an independent fail-safe: if the main IC fails, the Smart Fuse still acts.

Main IC: Undervoltage · overcurrent; Main IC shuts down before cell damage; 2 stages each
2nd IC: Overvoltage; 2nd IC blows the fuse, even with the main IC gone; 2 stages
Smart Fuse: Overtemp · short circuit; Smart Fuse stops severe accidents; 2 / 1 stages

Activation conditions fully customisable.

Catalogue notes

Pack-level cycle life depends on pack design and operating conditions and may differ from cell-level specifications.

The catalogue prints the length as “200 / 216(L)” without defining what the 200 mm figure excludes; both are reproduced as printed.

All values are subject to tolerances. Specifications are subject to change without notice.
