TerraE is a premium cylindrical battery cell provider, owned by Sven Bauer, CO & Founder of BMZ Group. TerraE's team of executives, engineers, and technicians defines cell specifications, which are manufactured by tier-one suppliers in Asia under the TerraE brand.

Long-term cooperation with Japanese cell engineers, the use of advanced materials, production on state-of-the-art production lines together with the best-in-class production process control.

We begin by auditing the factory and conducting product tests. Once a manufacturer meets our quality standards, they become a TerraE supplier. Additionally, we implement the Outgoing Quality Check (OQC) process and reporting standards. At the final stage of the supply chain, destination factories have their own incoming inspection guidelines to ensure quality.

Material costs are similar across all manufacturers. Thanks to fully automated production, carefully selected partners and high volumes of manufactured product, TerraE cell costs are competitive to well-known TIER-1 cell brands.
