DEAD BATTERIES PUT YOU BEHIND

DEAD BATTERIES PUT YOU BEHIND

KSM™ Supercapacitor KAPower® Starting Modules — Proprietary Starting Technology for Municipal Fleets

NEVER FALL BEHIND DUE TO A DEAD BATTERY

All Temperatures

Full starting power from -40°F to 149°F with zero degradation — cold winter mornings and summer heat alike.

No Maintenance

Proprietary supercapacitor technology means no replacement intervals, no battery swaps, and nothing for your maintenance team to manage.

Weatherproof Construction

Built to withstand the outdoor conditions your fleet operates in — rain, snow, heat, and cold.

1,000,000+ Start Cycles

A one-time investment engineered to outlast the vehicles it’s installed on.

Proprietary Starting Technology for Municipal Fleets

When any vehicle in your municipal fleet won’t start, the public feels it — delayed routes, slower response times, interrupted services. From police and fire to transit, public works, and parks, every vehicle in your fleet has a job to do. KSM™ installs permanently alongside your existing battery and delivers instant, reliable starting power every time — in any weather, after any length of storage.

Built for Every Vehicle in Your Fleet

Transit Buses

Routes run on time when buses start on time. KSM™ keeps your entire bus fleet reliable — from light-duty shuttles to heavy articulated coaches — regardless of battery condition or temperature.

Emergency Services

Police vehicles, fire apparatus, and ambulances can’t afford a no-start. KSM™ ensures your emergency fleet is ready to respond every time, in every condition.

Public Works & Utilities

Street sweepers, utility trucks, and maintenance vehicles sitting overnight in cold weather are prime candidates for battery failure. KSM™ eliminates that risk — permanently.

Support Vehicles

From inspection vehicles to parks and recreation equipment, KSM™ keeps every vehicle in your fleet operational — reducing service calls and keeping your team on schedule.

Real Stories from Real Boaters about our KBi System

"an added sense of security"
I couldn't be more pleased with the supercapacitor and the support provided by Kold-Ban in planning and executing the installation... It started the engine three times on it own with the battery disconnected! The ability to recharge the capacitor from almost any 12 volt source, if necessary, gives me an added sense of security

"service life is virtually unlimited"
Like all KBi supercapacitors, it is designed to augment and assist - rather than take the place of - a starting battery. Its boost considerably lightens the load of the existing starting battery, thereby extending its life... Unlike a battery, the KSM's service life is virtually unlimited.

"a win in my book"
.. I have switched to the KrankingKART MiniHD in all of our boats. With the 90 second recharge, we never have to worry about getting on site with a dead jump box... Logistically, it's been great for us. We can plan better, because we know we have capabilities beyond a traditional jimp box. Anything I can do to make the experience quicker for our customers is a win in my book.

"it's designed to last forever"
KBi's KSM is simple to install, and it's designed to last forever. As simple as is purpose may be, KBi's KSM is truly amazing. I'm shocked nobody came up with this sooner, as it's only a matter of time before every boat has one.

One Installation.
Zero Downtime.

KSM™ proprietary supercapacitor technology stores energy from your vehicle’s electrical system and delivers it instantly at startup — even when the battery is too weak to start on its own. With a service life of 15–20 years, 1,000,000+ start cycles, and zero maintenance requirements, it’s a one-time investment that outlasts the vehicles it’s installed on.

Try It in Your Fleet — At No Cost

We stand behind the performance of KSM™. That’s why we offer qualified municipal fleet operators the opportunity to evaluate a unit in their own vehicles before committing to a fleet-wide solution. Qualified fleet managers receive one KSM™ unit to install and evaluate — experience the performance firsthand, then decide if it’s right for your operation.
