Designed to outperform traditional lead-acid batteries on the road, on the water or off the grid, enjoy the freedom that comes with having more usable energy in a lightweight, no maintenance package that’s safe, reliable and worry-free.

The last thing you need when you’re getting ready for a fishing trip, game of golf or road trip is a battery that doesn’t power your application effectively. LiFePO4 batteries are one of the most durable and reliable energy sources on the market. And, they’re perfect for powering all of your adventures. Take the next step in green energy with rechargeable LiFePO4 batteries.

Certain applications benefit greatly from custom battery solutions. Watercraft, aircraft and other vehicles, for instance, have weight and balance specifications to meet, and customizing your battery helps meet those requirements. Our custom lithium battery packs offer turnkey solutions that combine lithium battery cells, a battery management system, mechanicals, communications and safety certifications.

Product Specification

Lithium Valley 500KWH 1MWH Energy Storage System

1.Scope of application
This system is suitable for the energy storage system ,it can be customized. The system is composed of multiple single batteries in series and parallel, and provides power for external equipment through a converter. The application of this energy storage system in the power grid mainly reflects In the following aspects:
1> Peak shaving and valley filling, by charging and storing energy during valley, and discharging energy during peak hours, reducing the electricity cost of enterprises or parks, and saving customers electricity costs

2>Demand response. When the short-term power consumption is greater than the capacity of the transformer, the energy storage system performs rapid discharge to meet the demand for electrical energy of the load.

3>Dynamic capacity increase, use energy storage equipment to replace the capacity of the voltage transformer at peak time, help users reduce the cost of transformer use, reduce transformer investment and expansion cycles, and conduct short-term power transactions on the power market trading platform in combination with load forecasts to maximize revenue.

4>Off-grid backup power supply provides uninterrupted short-term power supply for important loads when the power is interrupted, reducing the economic loss caused by the sudden power failure of the load.

2.Overall system design
This energy storage system consists of a 30-foot energy storage system container with a planned design capacity of 500kW/1MWh. The energy storage system container includes energy storage system, battery management system, PCS, UPS, EMS, lighting, fire protection, HVAC and distribution Auxiliary components such as electric access system, reserved for installation
/Maintenance channel; access to the power grid system of the plant area through the feeder cabinet of the power distribution room to achieve peak shaving, valley filling, demand management, energy saving, load balancing, dynamic capacity increase, power factor improvement and other functions. The electrical topology of the energy storage system is as spec listed.

Frequently Asked Questions

Can we put different LiFePO4 battery pack in parallel or series by ourself?

Yes. The battery can be put in parallel or series by customers. But there are few tips we need to pay attention; 1> Make sure the voltage/capacity of each battery are same before put in parallel. If they are not same, charge them to the same rate. 2> Don’t put used battery and new battery in parallel. This may reduce the capacity of the whole battery pack. 3> Advise us the target capacity of the whole pack if you would like to put them in series. We will choose the suitable BMS for each battery. 4> If you are not professional in parallel and series batteries, please don’t handle the battery by yourself. It may cause danger and hurt the cycle life of battery.

What’s the lead time for mass production?

It depends on the actual situation. 3-7 days with stock, if without stock, that will be depends on your order quantity, normally needs 20-25 days.

Can I be your distributor?

Yes, directly email to [email protected] we can discuss about this. We need to know your target market, what application you want to cover, and estimate yearly purchase volume.

How do you control the quality?

We have ISO9001 certification, from incoming materials to production, and then to delivery, there are corresponding QC control. Battery cells will be divided before assembly, and aging test will be conducted before the battery pack leaves the factory to confirm that it is normal before shipment.

What is your warranty?

We offer 5-10 years warranty for all our battery pack. we ensure at least 6,000 cycle life for the LiFePO4 battery pack, which means, after 6,000, 80% DOD, there will still around 80% capacity left. You can use it for at least 10 years for normal 1 time charge and discharge everyday.

How do you provide warranty?

Please check the attached warranty. During the warranty period and in the case of correct use, if there is a problem, we will provide new parts free of charge and guide replacement. If the feedback is unable to be repaired, we will replace the new products free of charge, but the problem products must be kept at your place, our engineers will go to help you check and repair.
