SkelStart Ultracapacitor Engine Start Module

A powerful module for reliable engine starting for large diesel engines under all weather conditions

The SkelStart Engine Start Module is the most powerful module for engine starting applications in the world. It’s based on Skeleton Technologies‘ industry-leading SkelCap ultracapacitors, which have the highest power density on the market.

Batteries are the leading cause for engine starting problems because of their short lifetime and vulnerability in extreme weather conditions. SkelStart takes the demanding job of starting the engine, protecting the battery and increasing its lifetime. SkelStart’s effective operating temperature range is from -40°C to +65°C , which makes it a perfect fit for bus, truck, rail and heavy equipment applications.
