Understanding Your Battery: Terms To Know
Understanding the basics of battery ratings and terminology is important when comparing and selecting the right type and number of batteries for your application to ensure you have enough energy to meet your energy goals.
We're Invested In Our Lithium Iron Phosphate Batteries
I had a terrible experience with 3x 225ah 8D batteries. The 50% to 80% SOC zone is not much power storage. I've added 2x 300HPs and while I only installed them 5 days ago so far so good. The power storage and more consistent voltage at just about any SOC has enabled installing an inverter and being able to use it, making stays on the hook a much easier experience.
