A POWERFUL STARTING MODULE SUITABLE FOR LARGE ENGINES UP TO 27L. RELIABLE UNDER ALL WEATHER CONDITIONS.


The SkelStart Engine Start Module is the most dynamic module for engine starting applications currently available in the world. Its design is based on Skeleton Technologies’ industry-leading SkelCap supercapacitors, which have the highest power density presently offered on the market.
SkelStart not only eases the demanding job of starting the engine but also protects the battery and increases its lifespan. SkelStart’s effective operating temperature range is from -40°C to +65°C, which makes it perfectly suited for bus, truck, rail and heavy-duty equipment applications.
There are no weather conditions too extreme on our planet that this robust module for reliable engine starting will not start under. The SkelStart Engine Module is the most powerful module for engines up to 27L in the world and the benefits of our technology justify the investment.












If you compare the two technologies, you may find that it is heavily stacked on one end. Our technologies are more compatible than comparable.
High Power (for starting)
Zero to full in minutes
Long Lifespan (1 000 000 cycles)
Works in extreme temperatures
-
High energy (for hotel loads)
-
-
Much higher peak power than batteries can provide
Temperature won’t affect starting power
Starting power even with “dead” batteries – If SkelStart’s energy is used, it needs min 9V and max 16 min to be charged from empty to full
More energy stored by the end of the work day
Battery lifespan will be increased 1,5 – 2x
There is no need to idle the engine to charge the battery
Fuel consumption decreases when the engine is idling from 6% to 2% = 400L/year.
Non-hazardous material (no lead, no acid)
Reduced fuel costs and CO2 emissions
Lifespan 1M cycles, no maintenance needed
Supercapacitors have been around since the 1960’s, but it’s only been in recent years that their potential has become better utilized. They are one of the most efficient energy storage devices available commercially. Ultracapacitor modules are a new type of energy storage device with excellent performance, high application values and incredible commercial potential.

SkelStart delivers a higher cranking power than batteries and does it effectively even at -40°C. Upgrade to SkelStart, and stop worrying about if you are going to be able to deliver on time or not.

Most batteries are unreliable at engine starting time, especially at low temperatures. SkelStart provides increased starting power output compared to a battery, even at temperatures of -40°C. Ideal for engine starting and start-stop applications.

Batteries will lose their charge over time and use. SkelStart will provide the highest cranking current to your gensets – in any weather condition.

Every minute counts when you’re working with heavy machinery and with a SkelStart installed, you can be sure there is no downtime because of batteries or starting issues.

Do you trust that your batteries will start the engine when it really matters? SkelStart can save your time, money, stress, and even your life by making sure you can find the charge to always get home.
Skeleton's ultracapacitors offer the highest power and energy density on the market, charging and discharging in minutes, high reliability, and providing very long lifetimes.
