HOW ITS MADE - WATCH NOW
Smart Battery line of 12V Lithium Batteries are built using our 3.2V 5AH Lithium Iron Phosphate Cells, The safest and most robust chemistry used for high capacity lithium ion batteries. Designed for applications that demand huge amounts of power and require high quality batteries that can withstand harsh conditions in rugged environments both on land and at sea. The bolted design of our cells provide strength to the pack and better current conductivity compared to tab welded cells. They bolt through length way circuit boards that keep the cells balanced and provided additional rigid strength to the pack.
| Standard BCI Group Sizes
Smart Battery Lithium Ion Batteries are the same size as standard lead batteries. Simply connect your cables and your ready to go.
Tip: Keep your battery connections bolted firmly to prevent power loss due to heat from resistance created with a loose connection.
3.2V 5AH Smart Cell
Every Smart Battery comes built with our 3.2V Lithium Iron Phosphate (LiFePO4) Explosion Proof Stainless Steel Cells. These cells bolt together for a strong firm connection and higher electrical conductivity compared to the tab welded method. Our cells are among the safety on the planet with multiple safety redundancy features.
Internal Cell Safety Fuse
Every cell has a built in thermal safety fuse between the anode and cathode that will internally break in the unlikely event the cell would begin to overheat.
High pressure safety vent
A high pressure safety vent will flip open to release energy and prevent explosion if exposed to extreme heat.
Flame Retardant Electrolyte
Our cells are manufactured with a flame retardant additive in the electrolyte making them safe.
explosion proof stainless steel
Every Smart Battery cell is manufactured in a explosion proof stainless steel cylindrical case.
Setting up your inverter charger.
Smart Battery Lithium Ion Batteries will work with any standard marine charger or alternator. We recommend programming your inverter/charger remote to 14.6V for Bulk and Absorb, and set the float to 13.6V.
How to connect your new Smart Battery - Plug & Play
The hardest part of switching your batteries to Lithium Technology will for sure be taking out your old batteries! Simply place the Smart Battery in your battery compartment, connect the cables and your ready to go.
