Avant Tecno’s subsidiary Avant Power started manufacturing batteries for their electric loaders in 2024. They have produced over 500 battery packs that enable a full day of work with a single charge for the Avant e-series loaders. Quickly gaining popularity, the OptiTemp® batteries signaled a new era for electric loaders in terms of capacity, longer operating time and lifecycle, safety, sustainability, and affordability. Now they’re taking the OptiTemp® concept further by introducing Avant Power’s first mobile and compact energy storage solution: the OptiTemp® Cube product line.

Mobile power for any application
The OptiTemp® Cube 50 is Avant Power’s answer to a growing demand for portable energy storage solutions in the loader and work machine market. It is an ideal companion for Avant’s e-series electric loaders. The OptiTemp® Cube 50 can provide the 27 kWh OptiTemp® battery with two full charges, and four charges for the 13,5 kWh battery. “As our battery production increases and more e-series loaders are being adopted, we have discovered that the OptiTemp® technology works equally well within portable energy solutions. Our loaders are often used at work sites without charging facilities. A portable power unit is ideal for providing more juice at construction sites, remote outdoor locations, forests, events, and many other applications. They are also great accessories for rental and leasing companies,” Avant Power’s COO Mikko Piepponen highlights.

While similar solutions exist, the OptiTemp® Cube is a unique product thanks to its immersion cooling technology, robust structure, and reliable performance in any environment. “The OptiTemp® Cubes are like our loaders in many respects: they are compact, durable, highly portable, quiet, and extremely safe,” Mikko says.

OptiTemp® guarantees premium performanceDespite their compact size, OptiTemp® batteries have a high power density that enables premium capacity and rapid charging. The OptiTemp® thermal management system keeps temperatures optimized when the battery is in use or plugged into a charger.

All cells are surrounded by a cooling liquid in the battery’s submersible structure. The immersion cooling system controls temperature and guarantees optimized performance in both freezing and hot weather. In cold conditions, the battery automatically pre-heats before use, and the temperature management system maintains operating temperature during use. The system also ensures that the battery won’t overheat, making it extremely safe to use.

“While the OptiTemp® Cube 50 is intended primarily as a companion for Avant loaders, the upcoming OptiTemp® Cube 100 will provide portable energy for all kinds of machinery, including mining and forestry. These products will pave the way for our larger solutions in the future. Stay tuned!” Mikko concludes.
