Definitely. No gas, no leaks, no thermal runaway like older chemistries. Plus, Power Queen batteries have built-in protections for various issues, including overcharging, over-discharge, overcurrent, high temperature, and short circuit.
You’ll be surprised how compact these are. They are small size and large capacity, making them suitable for most small boats, and only 1/3 the weight of an old-school battery(Vs. same-voltage &capacity lead-acid batteries).
Power Queen LiFePO4 batteries feature a durable design and a sturdy ABS case, making them well-suited for marine environments. They can handle bumps, motion, and wave impacts during typical boating use. For added protection, we recommend securing the battery firmly in a dry, well-ventilated compartment.
