Designed for boaters who value simplicity and reliability, the triple terminals allow you to organize and connect multiple devices seamlessly, reducing clutter and potential wiring confusion.
With triple terminals, you can easily separate system components and dedicate each set of terminals to specific wiring tasks—one for your outboard motor, another for your bilge pump, and a third for your electronics. This organized setup ensures each system operates smoothly and reduces the risk of electrical interference or overload.
With fewer parts and cleaner rigging, you’ll spend less time worrying about your setup and more time on the water doing what you love. Let Norsk Lithium’s advanced design take the complexity out of rigging for good.
A SMART LITHIUM BATTERY HEATER
Each Lithium Starting Battery features Thermal Core Heating Technology™
Our proprietary technology checks the temperature of the cells inside the battery and reroutes the inbound current from the charger to warm the cells if the cell temperature is below 32F. / 0C., Once the internal cell temperature has been increased to a safe charging temperature, the current from the charger is routed to the cells so a safe charge can take place.
This process is fully automatic, and controlled by the BMS built into each battery. More than a simple Lithium Battery Heater, this innovative technology ensures that your battery is always ready to perform when you need it most. This is a critical feature for anglers who enjoy taking advantage of fall fishing bites in northern climates. With the addition of full potting with thermally conductive epoxy, custom heat pads, and our proprietary heating control algorithm, NOBODY does heated batteries better!
BMS MEASURES INTERNAL TEMPERATURE
REDIRECTS CURRENT TO HEAT THE BATTERY’S CORE
BMS WARMS CELLS UNTIL THE INTERNAL TEMP REACHES 59F. / 15C.

HOW TO CHOOSE A LITHIUM STARTING BATTERY FOR YOUR BOAT
1. Determine Your Needs
Start by identifying your outboard motor’s cranking amp requirements. Check the manufacturer’s manual for the minimum cold cranking amps (CCA) or marine cranking amps (MCA) necessary for reliable starts. Ensure that your chosen Lithium Starting Battery meets or exceeds these ratings.
Additionally, consider any other accessories, like bilge pumps or electronics, that rely on the starting battery. A battery that can handle your outboard’s needs and additional loads will provide optimal performance on the water.
2. Set Your Budget
Utilizing a Lithium Starting Battery for your boat will save money and time over the long haul. Still, it’s an investment.
3. Compare Features for the Best Value
When selecting a Lithium Starting Battery, it’s important to compare features to ensure you’re getting the best value. At Norsk Lithium®, we pack our batteries with advanced technologies, offering superior performance and reliability. Our cutting-edge solutions provide more bang for your buck compared to the competition, making Norsk Lithium® the smart choice for your marine power needs.
Norsk Lithium offers two Lithium Starting Battery options in 120Ah (900CA) and 180Ah (1200 CA).
Here are the top three priorities when choosing a lithium starting battery
CRANKING AMPS
Refers to the amount of current a battery can deliver at a specific temperature, typically measured at 32°F (0°C), for 30 seconds while maintaining a minimum voltage. For more info on Cranking Amps
AMP HOURS (Ah)
Ampere hours, abbreviated as Ah or amp hours, is the amount of energy charge in a battery that enables 1 ampere of current to flow for one hour, or simply how long the battery can run.
SIZE
All Norsk Lithium batteries adhere to BCI specifications, eliminating the need for oversized, proprietary, expensive battery trays and difficult installations. For more info on BCI group sizes

“I am running (3) 100AH Norsk lithiums to power my 36-volt Minkkota trolling motor system. The first thing I noticed during installation was the huge weight savings over the lead-acid batteries I typically ran. After installing I ran them on my 21-foot fiberglass for 3 full-day guide trips at an average of 4.5-7 power on my trolling motor remote. They made it 17 plus hrs before finally needing a charge, very impressed!! I will never turn back to the heavy, undependable dark side of the lead acid batteries.”
– PJ VICK 
“
“I’ve never owned a battery where I didn’t have to worry about if my trolling motor was going to die or not. These batteries (100Ah Heated) last for days! Yes – days! Fished South Dakota for 3 days on a single charge and still had life left.”
– Jon K. (verified purchase)
