Frequently Asked Questions

What is Depth of Discharge (DOD) and why is it important?

DOD refers to how much a battery can be used relative to its total capacity. Higher DOD means more usable energy. This lithium battery's DOD is as high as 90%, compared to 50% of traditional lead acid batteries. 

What are the pros and cons of low-voltage batteries?

Pros of low-voltage batteries include lower cost, easy maintenance, and better compatibility. They are more affordable, require less effort to maintain, and work well with various systems.

However, there is a drawback. When the accumulative current in the system becomes too large, it can potentially lead to safety and efficiency issues.

But for residential storage systems below 20kWh, low-voltage batteries are a more balanced and economical choice.

When do I have to choose high voltage lithium deep cycle batteries?

Choosing high voltage batteries primarily depends on two key factors:

Inverter Compatibility: The selection of high voltage batteries should be based on the specific requirements of your inverter. It's essential to ensure that the voltage range of the inverter aligns with the batteries.

Large Capacity Needs: For systems where the battery capacity exceeds 20kWh, high voltage batteries are typically the preferred choice. Their efficiency and ability to handle larger energy demands make them suitable for such high-capacity applications.

What is the lifespan of the Lithium Deep Cycle Battery?

The lithium battery is designed for longevity, offering over 20 years of reliable service with good maintenance and favorable ambient conditions.

What is kWh and how long can a 5.12kWh battery last?

kWh stands for kilowatt-hour, a unit of energy representing the power of one kilowatt running for one hour. The duration a 5.12kWh battery can last depends on the load it's powering. For example, if you're using appliances that total up to 500 watts, the 5.12kWh battery would last for approximately 10 hours. However, for a 1000-watt load, it would last about 5 hours. The actual duration can vary based on efficiency and other factors.

How should a lithium battery be maintained and used for maximum lifespan?
  • Regular Charging: Avoid complete discharges. Charge the battery regularly without letting it drop to 0%.
  • Optimal Charge Levels: Maintain charge levels between 20% and 80% to reduce stress and extend battery life.
  • Ambient Temperature: Store and use the battery in moderate temperatures, avoiding extremes of heat or cold.
  • Proper Storage: If not in use for extended periods, store the battery at a 50-60% charge in a cool, dry place.
  • Avoid Fast Charging: Unless necessary, avoid fast charging as it can increase the battery's temperature and wear it out faster.
What's deep cycle battery?

A deep cycle battery is a type of battery designed to provide a steady amount of power over a long period. Unlike standard batteries that offer short bursts of energy, deep cycle batteries are capable of being discharged to a significant portion of their capacity without damage or reduced life expectancy. They are typically used in situations where energy needs to be supplied over extended periods, such as in solar power systems, electric vehicles, and marine applications. These batteries can undergo numerous discharge and recharge cycles, making them ideal for continuous, everyday use.
