DROP IN REPLACEMENT FROM LEAD ACID, GEL OR AGM BATTERIES


Smart Battery Lithium Ion Batteries are 70% Lighter and can last 10X longer than lead acid, agm and gel batteries. A lithium Ion Battery does not have voltage drop like a lead acid battery so when you crank your motor you will notice a faster start. 

Fish finders, Radars and transducers all perform better with higher voltage.

Lithium Ion Batteries do not heat up while charging like lead acid batteries. You will get around 15% faster recharge time with no heat loss. 

A lead acid battery is typically recommended to drain 50% and then recharge. therefore if you have a 200AH lead acid battery you are only getting about 100AH of usable energy. Smart Battery Lithium Ion Batteries provide 100% of usable capacity with no heat loss. A 12V 100AH Smart Battery will provide you with 100 amps of usable energy. 


  • Voltage Curve is nearly flat giving out higher voltage and power through out the cycle.

  • Holding the voltage higher during use provides higher torque for trolling motors, winches and starters. Other devices such as transducers and radar will have stronger and more accurate signals and readings.

  •  A 12V 100AH Smart Battery weighs 30 lbs. whereas a 12V 100AH AGM battery weighs typically 79 lbs.  The Smart Battery will run for up to 20 minutes longer at an 80A draw than an AGM battery.
