The Norsk 20.8Ah Lithium Battery BMS makes it fool-proofed and worry-free.  As a lithium ion battery ought to be.   

The BMS won’t allow the battery to receive a charge until its internal temperature has warmed to a safe 32F.  Once it’s safe, the BMS will allow the lithium battery to recharge, and you’ll be on your way!

Our advanced BMS technology also prevents your Norsk 20.8Ah lithium ion battery from overcharging.  

Even if you hook up your lithium-ion battery charger to the wrong terminals, the BMS will prevent it from receiving any charge.    

The BMS ensures cell balancing during discharge and charge cycles, low and high voltage cutoff, short circuit protection, and high-temperature protection. 


Just because cavemen caught fish doesn’t mean you must fish like them.  

The Norsk 20.8Ah Lithium battery’s patten-pending, dual USB ports allow you to enjoy the outdoors in the 21st century. 

These allow you to power your cell phone, go-pro, or nearly any USB-compatible device while your lithium battery powers your fish finder.
