CLARK Fusion' lithium-ion battery technology and the new multi-voltage charger for voltage classes of 48 and 80 volts sets new standards for efficiency and transparency in Intralogistics 4.0
Clark has unveiled its new fully integrated lithium-ion battery technology, Clark Fusion, at LogiMAT 2026 in Stuttgart, positioning it as a unified energy solution for electric forklift fleets operating across multiple voltage platforms.
Developed for Clarkā€™s complete range of electric powered industrial trucks from 48 to 80 volts, the Fusion system is designed to simplify fleet management while improving efficiency and reducing total cost of ownership. The launch also includes a new multi voltage charger capable of handling both 48 volt and 80 volt batteries, allowing a single charging solution across mixed fleets.
The Fusion batteries are compatible with Clarkā€™s full electric lineup, from compact three and four wheel models such as the S Series Electric STE16-20 and SE16-20 through to higher capacity trucks including the SE25-35, L25-35XE, S25-35XE and GEX40-50. Clark says the system has been engineered to provide a future proof platform for operations running varied equipment types within the same site.
Fast charging capability is a central feature, with most trucks reaching full charge in around two hours. Opportunity charging during breaks allows trucks to remain in operation across multiple shifts without the need for battery swaps. The new charger automatically adjusts to battery voltage and can be connected to either 16 amp or 32 amp sockets, reducing infrastructure requirements.
Energy efficiency is significantly improved compared to lead acid systems, with up to 95 percent of input energy stored in the battery rather than lost as heat. This reduces charging costs and shortens cycle times. The system also maintains consistent voltage output throughout discharge, ensuring stable lifting and travel performance across the full shift.
Fusion batteries are fully sealed and maintenance free, removing the need for water top ups, dedicated charging rooms or ventilation systems. This reduces space requirements and eliminates risks associated with acid handling and fumes. An integrated heating system supports operation and charging in sub zero environments by maintaining optimal battery temperature.
Service life is extended, with Clark stating that Fusion batteries can deliver at least twice the number of charging cycles compared to lead acid alternatives. In practice, a single lithium-ion unit can replace multiple lead acid batteries over its lifespan, while opportunity charging removes the need for battery changes between shifts.
The system is managed by an onboard battery management system that communicates with both the truck and charger via CAN bus. Operators can monitor charge status in real time through the vehicle display, while the system protects against deep discharge and overcharging.
Clark has also integrated 4G connectivity into the BMS, enabling remote monitoring and diagnostics. Fleet managers can access live battery data, receive automatic alerts and identify issues early, reducing unplanned downtime and supporting more predictive maintenance strategies.
The introduction of a standardised battery platform alongside connected monitoring reflects a shift towards more integrated energy management within electric forklift fleets, particularly where mixed truck types and high utilisation rates demand greater visibility and operational control.
