MRB06 Lithium-ion 7.4V battery pack

Rechargeable battery pack suitable for use with Vonyx megaphones. The ready-to-use battery replaces the need for six expensive D-cell batteries, significantly reducing the waste of standard batteries. Included is a USB charging cable that plugs directly into a USB adapter (not included) and provides several hours of continuous power to your megaphone once charged. Perfect for sporting events, parades and emergencies.
