Podium Advanced Technologies has designed a bespoke battery pack for
a full-electric extreme off-road motorsport application, where product
requirements dictated by the harsh operating conditions such as shocks
and vibrations, dust, extremes of temperature, are as crucial as peak
performances.
Podium Advanced Technologies has developed a unique module design
built into a bespoke battery pack, matching the severe structural, power
and mass performance targets set by the client.
The first battery pack prototype has been delivered in less than 10 months
from concept design.
