Frequently Bought Together
The Ionic 12V 125Ah Battery with Heater is a versatile, high-performance battery, ideal for 250 hp Yamaha and Mercury motors. With 900 cranking amps and an integrated heating system, it ensures reliable charging even in colder temperatures. This battery includes a Battery Management System (BMS) with power cut-off, recovery, cell balancing, and protection against low voltage, overvoltage, and short circuits. Proprietary software in the BMS ensures full compatibility with Yamaha and Mercury engines. Bluetooth technology allows for real-time monitoring, while a 99% Depth of Discharge (DOD) maximizes energy use. Lightweight (70% less than lead-acid) and built to last 3,000-5,000 cycles, it’s a drop-in replacement for a wide range of applications, including marine, RV, solar storage, and UPS systems. With the ability to connect in series or parallel, this battery is backed by an 11-year warranty for long-term reliability.

STORAGE CAPACITY
125 ampere hours (Ah). Ionic Lithium batteries provide dependable, consistent power throughout the entire 125Ah capacity. Unlike traditional SLA batteries, Ionic Lithium LiFePO4 batteries maintain a flat voltage curve, delivering steady power output as they discharge. This design ensures you’ll enjoy uniform performance right down to the last bit of energy.
Engine Starting Power
Lithium battery equivalent to 900 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive and other applications. Marine Outboards: Please refer to your manufacturer recommendations.

LIFECYCLES (BATTERY LIFESPAN)
Up to 80% capacity for 3,000 cycles under recommended conditions—compared to just 500 cycles for typical SLA batteries. Ionic Lithium batteries offer exceptional longevity, making the cost per use only a fraction of that of traditional batteries.
OPERATING TEMPERATURE
Engineered for rugged and extreme conditions, Ionic Lithium batteries outlast SLA and other lithium options. With an optimal operating range from -20°F to +140°F (performing reliably down to -20°F), these batteries are built to handle tough environments. Note: For best results, avoid charging below 32°F.
DISCHARGE
100A max continuous discharge, 350 A max pulse. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.
CHARGE
50a max, 14.4V recommended, 15V max Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.
INCLUDES ACTIVE BMS PROTECTION
Equipped with an advanced circuit, this battery ensures cell balancing, low and high voltage cutoff, short circuit protection, and high-temperature protection. These features boost performance and significantly extend the battery's lifespan.
