Battery Modules – Li-ion Building Blocks for Custom Battery Packs

Enepaq’s battery modules integrate 18650 and 21700 Li-ion cells into an easy-to-install format – no spot welding, no custom trays – so engineering teams can assemble a custom-capacity battery pack faster. CE certified, made in Europe.

What Is a Battery Module, and How Is It Different From a Cell or a Battery Pack?

A battery module is a pre-engineered unit of lithium-ion cells – arranged in series and parallel, wired, and protected – that acts as the building block for a larger battery pack. A cell is the single smallest energy-storing unit (like an 18650 or 21700 cell); a battery module groups multiple cells together – in configurations ranging from 1s1p to 1s10p and from 2s1p to 2s10p – into one pre-wired, protected unit; a battery pack is the finished product, made of one or more battery modules combined with a BMS, enclosure, and connectors.

Efficient, Safe, and Scalable Energy Solutions

Our battery modules are engineered to combine high energy density with advanced safety features, offering reliable performance across a wide range of applications. With their lightweight, compact design, they maximise power output while minimising space requirements, making them ideal for projects where efficiency and portability are critical.

Built to meet the highest international standards, our battery modules are certified for safety and durability, ensuring long-lasting operation even in demanding environments – from electric vehicles to renewable energy systems, our battery modules provide the flexibility and scalability you need to power innovation.

Modular Design

Cylindrical cells integrated within a pre-engineered format – no custom trays needed for your battery modules.

Simplified Connections

Battery modules connect using busbars and bolt kits – no spot welding or additional wiring necessary.

Scalable Assembly

Pre-configured battery modules combine faster than a custom cell layout, speeding up large battery pack assembly.

Air-Cooled Thermal Management

Strategic air gaps in each module’s housing circulate air and dissipate heat across the pack.

Integrated Sensors & Fuse Control

A JST 2-pin XH connector feeds module temperature data to your BMS, while built-in Fuse Control protects against overload.
