FEATURED PRODUCT - CUSTOM LITHIUM BANKS WITH REMOTE display

Why are our custom Lithium banks better than the competition?

Designed and custom manufactured in Canada, these battery banks utilize the highest quality components providing a reliable and cost effective energy solution for demanding marine applications.


The core of a Lithium battery is the cells.  Many "Name Brand" batteries use "No Name" Lithium cells that are average to poor quality.  MSI Lithium banks use cells from Contemporary Amperex Technology Limited (CATL), the number one Lithium cell manufacturer in the world.


A Lithium battery is a major purchase.  Do your due diligence and ask the vendor who makes the Lithium cells that are in the battery.  If the answer is "I don't know" walk away.  There are huge differences in quality between cell manufacturers.   CATL cells are subject to rigorous and comprehensive testing to ensure they are able to meet the heavy demands of a marine application.  These tests include nail piercing, crushing, hot box, short circuiting, over discharge, overcharge, and heat shock.  To view the detailed tests and cell specifications Click Here


Another key component is the Battery Monitoring System (BMS).  The BMS is the brain of the Lithium bank that controls and regulates the delivery of power.  It's tasked with protecting the bank from over charging and over discharging while monitoring its temperature and overall performance.  MSI Lithium banks use a high quality full featured BMS that has a remote display that can be mounted in your salon.  This display will show real time usage statistics including individual cell voltage, battery charge state, real time current draw, cell temperature and more. 


Lithium banks provide numerous advantages over their flooded or AGM counterparts:


  • Up to 10X the charge / discharge cycles (the bank will outlive the boat)
  • .5C charge rate, can accept continuous charge currents of up to 120A
  • Continuous discharge current of 250A
  • Peak discharge current of 500A (Capable of stating a marine engine)
  • Can be charged to full capacity in 2 hrs vs 20 hrs
  • 99% Charging efficiency vs 80-85%
  • Can be discharged to 10% vs 50%
  • Nominal current capacity of 250A with surge capability of 500A
  • 100% Maintenance free
  • Lightweight, 1/4 the weight of AGM batteries
