Built for the Field

The Merlin (RMBP64/12) is a new generation of 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 −20°C to 60°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 RMBC64/12 charging unit charges the battery in less than 5 hours, flat to full. A minimum of 600 recharge cycles can be achieved.

🧠

Built-In Analytical Computer

A built-in analytical computer allows battery performance data to be downloaded at any time — giving operators and maintenance teams full visibility of usage history, cycle count, and battery health.

🌡️

Wide Temperature Range

Operational from −20°C to +60°C, the Merlin covers every climate from Arctic deployments to tropical theatres without performance compromise or pre-warming procedures.

🛡️

Chemical-Resistant Nylon Casing

Both inner and outer surfaces are treated with a specialist nylon coating resistant to most chemicals including acids — suitable for use in contaminated or CBRN-threat environments.

🔋

State of Charge Display

A four-segment LED display gives an instant readout of battery charge state via a press-to-test button, allowing operators to assess readiness without specialist equipment.

🔌

Waterproof AMPHENOL Connectors

Military-specification AMPHENOL plugs and sockets are fully waterproof and supplied complete with dust caps, ensuring reliable connections in the harshest field conditions.

♻️

600+ Recharge Cycles

A minimum of 600 full recharge cycles before cell change is required — making the Merlin an extremely cost-effective long-term power solution for sustained operations.

Smart Battery Technology

The Merlin features a built-in analytical computer that logs operational data for download, allowing predictive maintenance and accurate readiness reporting across a fleet of batteries.

No Transport Restrictions

Ni-MH chemistry means the Merlin ships without dangerous goods classification, simplifying procurement and logistics through standard military supply chains worldwide.

From Arctic to Tropics

Tested globally, this product covers every area of operations without performance compromise in any climatic zone.

−20°

Sub-Zero Arctic Operations

Fully operational at −20°C without pre-warming. From Northern Europe to the Falklands, the Merlin delivers consistent power across the coldest operational environments.

60°

Desert & Tropical Environments

Equally capable at +60°C, ensuring reliable performance in the Middle East and tropical theatres where battery failure is not an option.

IP

Submerged & Wet Conditions

Waterproof AMPHENOL connectors with dust caps provide reliable sealing against moisture and particulates in rain, mud, and wet operational conditions.

NBC

Chemical & Contaminated Environments

Nylon-coated casing resists most chemicals including acid. External surfaces can be fully decontaminated without risk to the battery.
