What size fuse should be used when connecting two 36V 60AH Norsk Lithium marine batteries in parallel for my trolling motor?
Asked by Mason M. in South Dakota
ODIN
TECH GOD!Official AnswerNorsk Lithium recommends the installation of a fuse block on the positive terminal of each 36V 60AH battery wired in parallel to provide individual circuit protection for each battery, preventing significant damage in case of a short circuit or fault within one battery wired in the parallel configuration. A sample of the recommended fuse block and the 150A 58V fuse can be found on page 16 of our Marine product manual.

What is the lower limit voltage cut-off for my Norsk Lithium 36V marine battery?
Asked by Joshua C. in Nebraska
ODIN
TECH GOD!Official AnswerThe lower limit voltage cut-off for your Norsk Lithium 36V marine battery will be 30.0 volts.
If this low voltage limit is reached, the battery’s BMS will stop further discharge from taking place and the battery will enter Shut-Down Mode to protect the battery from damage caused by over-discharge of the battery’s cells

Should I use a battery maintainer while storing my Norsk Lithium marine battery?
Asked by Justin R. in Arkansas
ODIN
TECH GOD!Official AnswerThe use of a battery charge maintainer, often referred to as a “float charger”, is NOT RECOMMENDED by Norsk Lithium for use with lithium batteries. Using a maintainer that constantly tops off a battery’s SOC can cause metal plating within the cells that will significantly reduce the lifespan of the lithium battery. Because Norsk Lithium Marine Batteries have an incredibly low passive-discharge rate (<3% per month in normal operation mode) a battery maintainer for long-term storage is unnecessary. Any damage caused by the use of a battery charge maintainer IS NOT covered by warranty.

How is my Norsk Lithium Marine Battery shipped?
Asked by Anthony W. in Pennsylvania
ODIN
TECH GOD!Official AnswerTo comply with DOT regulations, Norsk Lithium Marine batteries must be shipped as Class 9 hazardous materials. This requires the use of packaging that meets specific thickness standards and is properly labeled for hazardous transport. We deliver our products to customers through trusted carriers, including FedEx, UPS, and USPS.

I have 5 Norsk batteries (2) 36V for trolling motor, (2) for starting, (1) dedicated graph battery. This is my first year with them and the research I have done says take them to 50% before putting them to sleep. I charged them about a month ago and never made it back out. They are all mostly charged still. Wondering if there is a way to discharged them before I put them to sleep. I am in North Dakota and have pulled them out and have them on a shelf in the heated shop for the winter already.
Asked by Travis C. in North Dakota

TECH GOD!Official AnswerFor optimal performance and longevity, store your Norsk Lithium Marine batteries in a cool, dry location with a charge level between 50–60%.
Since your batteries have already been removed from your boat, you may either discharge them to the recommended range using an external source or store them at their current charge for this season. When preparing for storage in the future, aim to maintain the 50–60% charge level. Storing batteries at a higher charge for a single season will not cause harm; it would require multiple years of high-charge storage to negatively impact the lithium cells.
If you choose to discharge your batteries before long-term storage, the simplest approach depending on your setup is to connect them to your boat’s equipment (such as the trolling motor or electronics) to draw down the charge. If the boat is already in storage, you can use a high-voltage LED light bar (rated up to 48V) connected to the battery terminals to safely reduce capacity.
Once your battery is charged and ready for storage, we recommend placing it into Deep Sleep. This function completely disconnects power from the terminals, preventing any drain from electronics or accessories and helping preserve the battery’s charge.
Deep Sleep can be activated through the Norsk Guardian App or by pressing the Power Management Button located on top of the battery case until 3 lights are illuminated.
For additional details, visit the Norsk Lithium website.
**Storing your batteries at the 50-60% battery capacity is ideal conditions. Storing your batteries at a higher battery percentage will not harm them for one season; it would take multiple years of long-term storage at a high battery percentage to negatively affect the lithium cells.

What is the appropriate temperature to store my battery? Both short term and long term. And are there temperature extremes i should stay away from? Thank you.
Asked by Mark N. in Alabama
ODIN
TECH GOD!Official AnswerFor short-term storage, keep Norsk Lithium batteries in a cool, dry place between 32°F(0°C) and 77°F(25°C). For long-term storage, a temperature range of 40°F(4°C) to 60°F(15°C) is ideal, with the battery charged to about 50–60%. Avoid extreme temperatures during storage, below -4°F(-20°C) or above 113°F(45°C),as this can cause permanent damage or shorten battery life.
We recommend after charging your battery to about 50–60%, to put the battery into Deep Sleep for storage. Deep Sleep cuts all power to your battery’s terminals to ensure your electronics & accessories will not be able to drain off of it, as well as preserving your batteries charge percentage.
This feature can be implemented using the Norsk Guardian App or by using the Power Management Button on top of the battery case.
