Description:

Usually, we can manufacture on demand a plenty battery packs in standard configurations, starting with 3s3p to 12s12p of rectangular or square shape. These can easily be found on the inventory page. As well, we can maximize the yield through assembling a more customized battery, molded on vehicle specs and engineered almost in any form or capacity! This is the key to develop a high-performance UAV designed with powerful battery packs, to achieve a long-range flight with more payload.
