Not only does the LiFePO4 battery offer longevity, but it is also lightweight and easy to move. Weighing only 1/3* the weight of lead acid batteries, it is 50% lighter while offering the same capacity.
With an impressive efficiency of 95%*, the LiFePO4 battery's flat discharge curve holds above 12.8V for up to 95%* of its capacity usage. This means you can enjoy extended run-time compared to traditional Lead Acid batteries, which only provide 50% capacity usage. Whether you need power for outdoor camping or easy indoor installation, this product is your best choice.
For those using trolling motors, this 12V 50Ah battery is suitable for energy storage and supports a max. discharge current of 1C. If you require a battery for a 30~70lbs thrust trolling motor, we recommend the 12V 100Ah battery. For recommendations on other models of trolling motors or starter batteries, please feel free to contact us.
