SkelStart
The most powerful
engine start module
in the world
The SkelStart Engine Start Module is a supercapacitor engine start module. It will start your engine anywhere, every time, and will crank any large diesel engine reliably, time after time.
Supercapacitors are an energy storage technology similar to batteries, but their strengths are different: very high power, 10+ year lifetime, and excellent reliability, even in extreme temperatures.


SkelStart Engine Start Module 24V
A powerful module for reliable engine starting for diesel engines in any weather conditions
The SkelStart Engine Start Module is the most powerful module for engine starting applications in the world. It's based on Skeleton's industry-leading SkelCap supercapacitors, offering unparalleled power.
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, while protecting the battery and increasing its lifetime. SkelStart's effective operating temperature range is from -40°C to +65°C (-40°F to +149 °F) , which makes it a perfect fit for bus, truck, rail, and heavy equipment engine starting.
