Three-Pack Li-Ion Replacement

The Kastar MX990 pack supplies three 3.7 V lithium-ion cells rated at 1900 mAh and 7.03 Wh each. They are built for users of Panasonic WX and BX series headset systems who need ready spares for long shooting days or multi-camera setups.

Direct Drop-In for Panasonic Systems

Each battery replaces the original WX-B3030, WX-B3030M, BX-B3030 or CE-3030 pack and fits the WX-T3020, WX-H3030, WX-H3050, WX-CH450 and WX-CT420 headsets without adapters. The triple pack lets you rotate cells through the charger so a depleted unit never stalls a session.

Built-In Protection Circuit

Integrated safeguards prevent over-charge, over-discharge, over-voltage, over-current and over-heating events during normal use. Cells meet UL1642 and CE safety standards, so they run cool and stable across typical duty cycles. Not suited for devices that require a different voltage or form factor.
