48V Lithium Battery 300Ah Features

Partial State of Charge Tolerant

Partial state of charge, known as PSOC, which is a killer of lead-acid battery, does not affect performance or battery life of a lithium battery. Sometimes battery don’t get fully charged, or they regularly operate in a partial state of charge. Either way, you can count on lithium battery living a long and productive life.

Maintenance Free

Plug, play, and charge. No watering, no corrosion.

More Usable Capacity

Lead-acid battery are typically sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are typically cautioned to limit your use to 50% of the rated capacity, as using more can significantly reduce performance. Lithium battery provide 100% of their rated capacity, regardless of the rate of discharge. And, you can use it all and still get substantially longer cycle life.

Long Life

lithium battery provide up to 10 times longer life than lead-acid battery, and they still provide 80% of the rated capacity after 3,500 cycles.

Constant Power

Full power available throughout discharge. Voltage does not drop like lead-acid.

Temperature Tolerant

Lithium battery can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C).

Eco-Friendly & Safe

lithium battery are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous battery.

Highly Efficient

lithium battery have super low resistance, allowing you to charge much faster. And lithium battery are 99% efficient, minimizing the losses during charge. Compare that to traditional lead-acid battery at 75-80% efficiency, which results in significant loss when recharging.

Fast Charging

lithium battery charge much faster than traditional lead-acid battery, and they’re packed with more usable energy and up to 10 times longer life so you’re always ready to go!
