CHARGEX® EnergyWave
Heavy Duty Battery Protection System
Our Lithium Iron Phosphate Batteries are built with a first class Fully Automatic Built-in Battery Protection System (BPS)
This highly advanced internal battery protection system automatically turns the battery off if it's drained below 8V or charged above 16V - preventing accidental over discharge. The Battery Protection System will turn off the battery by sensing a short circuit, reverse polarity, over and under voltage, as well as, over current. This Built-in Battery Protection System maximizes the efficiency and performance of the battery to increase its cycle life.

Bolted Together for Superior Strength
CHARGEX® Lithium Iron Phosphate Batteries are bolted together using our 3.2V 6AH Stainless Steel Cylindrical Cells which adds rigid strength and superior current conductivity compared to the lesser quality tab welded method.
Further adding to the safety and reliability, each cell bolts through our lengthway circuit boards that add additional strength to the battery while providing individual cell balancing and short circuit protection.
When compared to tab welded cells, our lithium ion batteries are more robust in marine and automotive environments that high vibration often causes lesser quality tab welds to break apart rendering the entire battery useless.
Lengthway Circuit Boards
CHARGEX® Lithium Iron Phosphate Batteries are made with our 32700 - 3.2V 6AH Stainless Steel LiFePO4 cells that are bolted together through our lengthway circuit boards.
The lengthway circuit boards provide rigid strength to cells core and are connected to the heart of the system's BMS that will balance individual cells.

CHARGEX® 3.2V 5AH Lithium Iron Phosphate - LiFePO4 Cell
Thermal Fuse
Internal Cell Safety Fuse
Our latest cell technology 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.
Safety Vent
High pressure safety vent
A high pressure safety vent will flip open to release energy and prevent explosion if exposed to extreme heat.
Electrolyte
Flame Retardant Electrolyte
Our cells are manufactured with a flame retardant additive in the electrolyte making them safe.
Explosion proof
explosion proof stainless steel
Every Smart Battery cell is manufactured in a explosion proof stainless steel cylindrical case.
MORE STARTING POWER
Guaranteed to start your engine faster.
More Voltage = 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.
Our lithium batteries hold a steady voltage above 13V giving your starter all the power it needs to start your engine noticeably faster and stronger.
Setting up your inverter charger
Our lithium batteries will work with any standard marine charger or alternator. We recommend programming your inverter/charger remote to 14.6V for Bulk and
Connecting multiple batteries in series or in parallel
Our lithium ion batteries can be combined in series to increase voltage or in parallel to increase capacity. The built-in battery protection system independently maintains the cells and keeps the battery operating at its maximum capacity for thousands of cycles.
Charging
Our 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
Standard BCI Group Sizes
Our 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
Solar Charging
Our 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.
