28.8V 3.2Ah (92.2Wh) Lithium Ion Battery (15A capable)

The CMX820P is a high power 28.8V 3.2Ah Lithium Ion Smart battery with a stored energy of 92.2Wh. 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 CMX820P allows it to discharge continuously at up to 15A (or 330W 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 CMX820P 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 CMX820P 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 CMX820P meets the requirements of IEC 62133:2012 (Safety), UL 62133 (Safety) and UN 38.3 (transportation). If your application requires the battery to be certified to IEC 62133-2:2017 please contact us.

The CMX820P 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.
