BSLBATT® Marine Lithium Batteries are the industry’s preferred dual purpose lithium marine batteries for starting and deep cycling. From luxury yachts to fishing boats, our BSLBATT lithium marine batteries come with a five-year warranty. In each BSLBATT marine lithium battery, a built-in battery management system (BMS) protects the battery from overvoltage and voltage, making it a simple plug-and-play replacement for any marine application. Each cycle, the BMS will also maintain and balance the battery to ensure maximum capacity. In addition to giving you a ten-fold increase in battery life, our batteries are 70% lighter, charge in a third less time, and require no maintenance, no water additions, and no odors.

For maximum flexibility, BSLBATT is a deep cycle and starting dual purpose battery suitable for 12V, 24V, and 36V trolling motors. With our marine lithium batteries, your trolling motor will always run at top thrust, even when the battery voltage drops below 13 volts. The voltage of lead batteries starts at 12.8V and quickly drops to 11V in strong currents or winds. As a result, your motor runs slower when you need it most. The Smart Batteries use LiFePO4 lithium iron phosphate chemistry, a strong electrolyte that can store large amounts of energy. As a result, your trolling motor will be able to run for nearly 6,000 fishing trips before it needs to be recharged.
