CMX420M

14.4V 5.1Ah (73.4Wh) Lithium Ion Battery (20A capable)

Status: 'Pre-Production'

The CMX420M is in Pre-Production. Please contact us for sample availability.

The new CMX420M is a high power 14.4V 5.1Ah Lithium Ion Smart battery with a stored energy of 73.4Wh. It is designed to meet the demanding needs of medical device manufacturers and comes equipped with a level of technology and regulatory compliance that will provide the next generation of medical devices with a real competitive edge.

The latest Nickel-Manganese-Colbalt Lithium ion cell technology within the CMX420M allows it to discharge continuously at up to 20A (or 220W continuous) making it ideal for high power transportable devices - either as a primary power source or as a redundant backup supply.

The industry standard smart battery interface on the CMX420M allows a host medical device to ascertain pertinent information such as state-of-charge, remaining runtime, cycle count and serial number, all of which allow the device to provide useful real-time data to the user. When connected to a compatible smart charger the CMX420M communicates its charging voltage and current requirements which are then provided by the charger - this system increases both safety and battery lifetime as the battery remains in control of its charging regime.

A clear 5-bar LCD display on the rear of the battery provides a quick visual capacity reference for the user so they can decide which batteries need charging and which can be used.

The CMX420M meets the requirements of IEC62133-2 (pending), UL62133 (pending) and UN38.3 (pending), meaning that that it can be quickly and easily designed into the next generation of medical devices with minimal cost to the OEM.

The CMX420M ships with Entellion branding, white casing and a standard software set-up. All of these can be customised to suit a particular OEM requirement - please contact us to discuss.
