Built for the Field

The Hawk IIA (RMBP64/24B) is a new generation of Ni-MH (Nickel Metal Hydride) battery. This unit is one of, if not the most advanced smart batteries in the world today. With its vast range of working temperatures −30°C to 70°C, these batteries can cover all areas of deployment from the Arctic through the Tropics. Both the outer and inside of the case have been treated with a special nylon coating which is resistant to most chemicals, including acid. A four-segment LED display shows the battery state of charge by a simple press of a button. A built-in analytical computer allows information to be downloaded from the battery at any time. All plugs and sockets are the Military AMPHENOL type and are totally waterproof, complete with dust caps. The purpose designed RMBC64/24 charging unit charges the battery in less than 5 hours, flat to full. A minimum of 600 recharge cycles can be achieved.
