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.

Never boost batteries again!

Beat winter.

How It Works

SkelStart is installed between the batteries and the starter, which means the batteries are disconnected from the starter.

 

SkelStart will always provide the starting power for the engine, and the batteries will only need to provide energy for lights, air conditioning, heating, etc.
