Weight reduction! Lithium batteries that achieve lightweighting for industrial vehicles.

Lighter than lead batteries by about 1/3! Improved driving performance through weight reduction in industrial vehicles!

Overwhelming energy density (lightweight and compact) Achieving the same amount of electrical energy as lead batteries with overwhelming lightness. It is now possible to reduce the total weight of the vehicle by several hundred kilograms, minimizing damage to the floor and loss of driving energy. Improved loading efficiency (maximizing payload) With lighter batteries, it is possible to carry more cargo or higher-functionality optional equipment. This greatly contributes to improved work efficiency. Low center of gravity design and layout flexibility Not only lightweight, but also customizable in shape. This allows for optimal placement within the vehicle, supporting advanced vehicle balance design such as improved stability during turns. Easy weight reduction without charger replacement Our batteries can be designed to use existing lead battery chargers as is. This enables upgrades to lightweight and lithium technology while keeping capital investment to a minimum. Reliability through domestic self-inspection While pursuing weight reduction, we maintain robustness and safety suitable for industrial applications. We deliver only products that have passed strict inspection standards.

From Lead to Lithium: A Battery Replacement Solution with Reduced Initial Investment

No need to replace the charger when switching from lead batteries! Minimize equipment investment and achieve the long lifespan and high efficiency of lithium.

Existing chargers can be reused as is. The cost of replacing with a lithium-specific charger and the electrical work for installation will be reduced to "zero." A smooth transition utilizing existing infrastructure is possible. No modifications needed on the vehicle side (plug-in replacement). By customizing the shape and voltage to match existing lead batteries, operations can start simply by swapping them out without changing the circuit design on the vehicle side. Extending lifespan reduces the "number of replacements." With a cycle life more than three times that of lead batteries, future battery replacement costs can be significantly minimized. Support for small lots and shortest delivery times. Replacement can be done from just one unit. Instead of changing all vehicles at once, it is possible to first trial with one unit and then gradually proceed with lithium conversion according to your budget. "Fail-proof" implementation support through domestic in-house inspection. Vehicle specifications are checked in advance, and shipments are made with optimal settings. Hidden costs due to post-implementation troubles are thoroughly eliminated.
