Plug & Play
Simply Connect your battery cables and you're ready to go. Every Smart Battery has a built in battery protection system keeping it running at peak performance for thousands of cycles.
Smart Battery Lithium Ion Batteries can be connected in series and in parallel. Our internal battery protection system requires zero maintenance for the life of the battery.
Built in Battery Protection
70% Lighter than Lead
Yachts with large battery banks can typically reduce 70% of there weight and use around 1/3 of the space required for the same amount of power as their lead bank.
100% Depth of Discharge (DOD)
Safely use 100% DOD (depth of discharge) meaning you can expect to nearly double your capacity when comparing to the same size lead acid, gel or agm battery.
Long Life 3000 - 5000 Cycles

Lithium Trolling Motor Batteries
Smart Battery's work with all 12V, 24V, and 36V trolling Motors and offer the greatest flexibility as a dual purpose battery for deep cycle and starting. Our lithium batteries hold above 13 volts for most of the time your trolling giving your motor the power it needs to keep the running at its highest thrust throughout the entire day. In contrast lead batteries start there voltage at 12.8V and quickly go down to 11V in in strong current or winds causing your motor to run slower when you need the power the most. Smart Battery uses LiFePO4 Lithium Iron Phosphate chemistry, a strong electrolyte capable storing an extreme amount of power for over 10 years while providing 100% usable capacity powering your trolling motor for the next 3000 fishing trips.
MORE VOLTAGE IS MORE POWER
When you start your motor a heavy load is placed on your battery, Voltage in lead acid and agm batteries starts out low and can drop below 10V during cranking causing your motor to spin over slowly. Smart Battery Lithium Batteries hold a steady voltage above 13V giving your starter all the power it needs to start your engine noticeably faster and stronger than lead acid batteries.
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.
Connecting multiple batteries in series or in parallel
Smart Battery® Lithium Ion Batteries can be combined in series to increase voltage or in parallel to increase capacity. The Built In Battery Protection independently maintains the cells and keeps the battery operating at it's maximum capacity for thousands of cycles.
Smart Battery® Lithium Ion Batteries can be recharged with any standard charger, alternator and charge controller designed to charge Lead Acid, Gel or AGM Batteries. In some cases if your charger does not reach a high enough voltage it may not fully charge the battery. We offer a line of 12V Lithium Battery charger designed to provide maximum performance and longest life out of our batteries. To view our Chargers Click Here
Standard BCI Group Sizes
Smart Battery Lithium Batteries are the same group sizes as Lead Acid Batteries. Simply connect your cables and you're ready to go. The built in battery protection system will automatically disconnect if you accidentally touch the positive and negative terminal together with a wrench or if the battery is accidentally wired backward. After you install the battery and connect your cables you can immediately use the battery. Unlike other Lithium batteries that require sophisticated external wiring to battery management systems, our line of Drop In Replacement Lithium Batteries are " Plug and Play " requiring no maintenance for life. Install once and your done.
Smart Battery Lithium Batteries work with all standard Solar Charge Controllers. Our batteries are 99.1% efficient and able to absorb nearly 100% of the energy from your solar system whereas your lead batteries can lose over 25% of the power from your solar panels due to resistance.
Tip: Keep your battery connections firmly tightened, a loose terminal will heat up and cause resistance.
3.2V 5AH Smart Battery® LiFePO4 Cell
Every Smart Battery® is manufactured with our 3.2V Lithium Iron Phosphate (LiFePO4) Explosion Proof Stainless Steel Cells. These cells bolt together for a firm connection and more electrical conductivity compared to the tab welded method. Our cells are among the safest on the planet with multiple 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.
