What is an energy storage lithium battery?

A lithium-ion storage battery repeatedly embeds and disembeds lithium ions between positive and negative electrodes to achieve charging and discharging. These batteries can store renewable energy sources, such as solar and wind power, and release the stored energy when needed.

What are the types of lithium batteries for energy storage?

There are various types of lithium batteries commonly used for energy storage, including lithium cobalt oxide, lithium iron phosphate, and lithium nickel manganese cobalt oxide (also known as ternary material).

How long can an energy storage lithium battery last?

The lifespan of an energy storage lithium battery is influenced by factors such as capacity, quality, and usage patterns. Typically, these batteries can last anywhere from 5 to 15 years.

How to choose the right energy storage lithium battery for you?

To choose a suitable storage lithium-ion battery, multiple factors need to be considered such as system capacity, power, cost, operational lifespan, etc. A corresponding plan should be developed based on individual needs and budget.

What do I need to pay attention to when installing and maintaining energy storage lithium batteries?

Proper installation and maintenance of energy storage lithium batteries require adherence to relevant safety regulations and the involvement of trained professionals. Additionally, it’s crucial to prevent overcharging and over-discharging, maintain the battery in good condition, and replace it when necessary.

What are the advantages of lithium batteries for energy storage?

Energy storage lithium batteries offer numerous advantages, including the ability to store electricity, regulate grid load, enhance energy utilization efficiency, and reduce carbon emissions. These benefits contribute significantly to the promotion of energy transition and sustainable development.

I need more function such Bluetooth and LED screen,i also want anti vibration design for using at my Marine/RV/Vehicle can i customized my battery pack?

Yes of course, just let me know what exactly you need, our professional engineer team will give you an excellent solution, more than you expectation.

I'm very sensible in price, i am a wholesaler of battery pack, if i sell your battery pack in my city, the profit is very low, can i get a cheaper price? and i can see your competitor sells cheaper than you.

It is highly suggest that you can have a comparison with our competitors. There are too many suppliers providing low price battery pack by using cheap materials, especially recycled battery cells. Blueleph offers a wide price range for models with different cycle life and warranty to cover different market requirement. Please tell me your target price so that we could recommend the correct models to you. 

I can see the post that your company shows the warranty is 7 Years, so no matter how the battery pack be used, the warranty will be valid for 7 Years?

No sir, maybe you know the cycle life of cell not only depends on the quality itself , but also is affected by the discharge/charge rate, the actual temperature and other operation conditions. So it doesn’t make any sense if a supplier tells you the cycle life without talking about the operation condition. For room temperature 25℃ and 1C discharge and 0.5C charge, the cycle life of the battery pack can exceed 6000 cycles and warranty 7 Years, only energy storage application.
