Key Takeaways:

• The Risk: A dead battery jump start 20 miles offshore is dangerous; relying on jumper cables in rough seas is a recipe for disaster.
• The Lithium Problem: Traditional jump starting techniques can damage sensitive Lithium (LiFePO4) Battery Management Systems (BMS).
• The Solution: KBI supercapacitor technology acts as a permanent, onboard jump starter, delivering the instant power needed for marine engines.
• MKSM is now BoatStartPlus: We are rebranding our heritage technology under BoatStartPlus to provide the ultimate safety net for marine vessels.

Turn the key (or push the button), and… nothing. Maybe a single click. Maybe the whole helm goes dark.

If this happens in a parking lot, you call AAA. If this happens 20 miles offshore, you are in a survival situation. According to US Coast Guard statistics, machinery failure is consistently one of the top contributing factors to boating accidents.

Performing a dead battery jump start on a boat isn’t like doing it on the roadside. You can’t just flag down another boat, and trying to connect cables between two rocking vessels in a swell is dangerous for both the crew and the electronics.

We are seeing a massive shift to Lithium (LiFePO4) batteries in the marine world. While they are incredible for “house” loads, they have created a new, silent crisis when it comes to engine cranking.

The Problem with a Traditional Jump Start on Lithium

Everyone loves lithium for running trolling motors and fish finders. But starting a large marine engine is a violent event. It requires a massive spike of amperage—often more than a standard lithium battery can safely deliver.

When you attempt to crank a heavy engine with a lithium bank, two things happen that make a standard dead battery jump start complicated:

• The BMS Trip: Lithium batteries have a safety computer called a Battery Management System (BMS). When the starter motor demands 800+ amps, the BMS sees this as a “short circuit” and cuts the power instantly. You aren’t just dead; you are locked out.
• The “Voltage Sag”: If you try to jump start a dead cranking battery using your house bank, the sudden voltage drop can reset your navigation equipment (GPS, Radar) right when you need it most.

The BoatStartPlus Solution: The “Internal” Jump Start

This is where KBI Supercapacitor technology changes the game.

Instead of worrying about carrying cables or calling for a tow, BoatStartPlus acts as a permanent, self-contained jump start system.

A supercapacitor stores energy electrostatically, meaning it is always ready to dump a massive charge instantly. By installing this system, you separate the duties:

• The Battery handles the slow, steady electronics.
• The Supercapacitor handles the violent energy spike to start the engine.

This means you never have to perform a dead battery jump start with cables again. The power is already there, sitting right next to the engine, immune to the cold and ready to fire.

Enter BoatStartPlus

At Koldban, we are consolidating our tech under a new banner: BoatStartPlus.

If you’ve used our MKSM products in the past, you know the reliability we’re talking about. We are taking that heritage and applying it specifically to modern marine environments where safety is paramount.

BoatStartPlus utilizes KBI supercapacitor technology to ensure that when you hit the Start button, the engine fires—regardless of how cold the water is or how depleted your battery might feel. It is the ultimate insurance policy against the dreaded “click-click-click” of a dead system.

Stop worrying about your next dead battery jump start. Equip your vessel with BoatStartPlus at Koldban.com.
