SkelStart
Engine Start Module
The SkelStart Engine Start Module (ESM) is an ultracapacitor that replaces traditional batteries, offering superior starting power. Unlike batteries, which loses up to 50% capacity in cold temperatures and require frequent boosting and replacements, ESMs deliver 95% power even at -40°C.
