Unconditionally fast discharging

VOIMA means "force" in Finnish. Despite the fact that the products of this line have been tested in a number of adverse and harsh conditions, they perform at the top level - unconditionally.

Where impulse power and fast discharge are needed, VOIMA batteries outperform. They are an ideal solution for instance in micro-hybrids and to serve as an emergency power supply in different conditions. VOIMA is your safe and durable choice for applications traditionally served by supercapacitors. Be it in a railway transport, bus, or a loader, VOIMA will power the machine in a blink of an eye.
