Q Can I be your distributor?
A Yes, please send an email to christin@lithiumvalley.com so that we can discuss this further. We need to know who your target market is, what applications you want to cover, and how much money you spend each year.
-
Q How do you provide warranty?
A Please review the enclosed warranty. If there is a problem during the warranty period and in the case of proper use, we will provide new parts free of charge and guide replacement. If the feedback cannot be repaired, we will replace the new products at no cost; however, the problem products must be kept at your location, and our engineers will come to assist you in checking and repairing them.
-
Q What’s the lead time for mass production?
A It depends on the actual situation. 3-7 days with stock, if without stock, that will depend on your order quantity, normally needs 20-25 days.
-
Q What is your warranty?
A We offer 5 years warranty for all our battery packs. The specific warranty requirements are stipulated on our warranty page.
-
Q How do you control the quality?
A We have ISO9001 certification, and there is QC control from incoming materials to production and then to delivery. Before shipment, battery cells will be divided and an aging test will be performed before the battery pack leaves the factory to ensure that it is normal.

Q Can we put different LiFePO4 battery pack in parallel or series by ourselves?
A Yes. Customers can connect the battery in parallel or series. But there are a few things to keep in mind: 1> Before connecting batteries in parallel, make sure their voltage/capacity is the same. If they are not the same, charge them at the same rate. 2> Never connect a used and a new battery in parallel. This may reduce the capacity of the entire battery pack. 3> If you want to connect them in series, please tell us the total capacity of the pack. We will select the appropriate BMS for each battery. 4> If you are not experienced with parallel and series batteries, please do not handle the battery on your own. It may be dangerous and shorten the battery's cycle life.

Q How do we maintain the health of LFP Battery?
A For LFP, no more maintainance is needed, for that BMS can keep it safe by monitoring the battery status. While there are still several important things to notice:
Preference Temperature(4-35℃).That the temperature is too high or too low will cause a positive impact on battery life.
Appropriate Frequency. Only by using it frequently can LFP battery show the best performance. If you might use it a little less often, it’s advisable to achieve a complete charge and discharge monthly.
Avoid being mixed with metal in case that the metal is in contact with electrodes. If severe, it will cause a short circuit accident.
Appropriate surroundings.The LFP battery should be placed in a clean, dry and ventilated environment, avoid contact with corrosive substances, and keep away from fire and heat sources.

Q What’s the difference between Single-phase UPS and 3-phase UPS?
A Key differences between single-phase and three-phase UPS output:
-Both supplies have a different number of conductors (three vs five).
-Both supplies have a different output number of sine waves (one vs three).
-A single-phase voltage is 230V whereas a three-phase voltage is 415V.
-A single-phase connection is less complicated than a three-phase UPS.
The choice between them depends on your scenario and the power your device is connected to. You need to identify the load that the UPS will protect and assess its voltage range. Generally, loads less than 20kVA can safely use single-phase UPS, or larger loads tend to use three-phase UPS power.If you are still unsure whether your application requires a single or three-phase output, get in touch with our experts to help you select the right system for you.

Q How do we make a profit after installing ESS?
A Initially, ESS installation might make you pay a premium. While in the long term, there is no doubt that you return can offset costs.
For the family unit, home storage can reduce the cost of electricity by increasing the proportion of self-generated and self-consumption, participating in auxiliary services, etc., and at the same time, it can be used as an emergency backup power supply in the face of major disasters and other factors that lead to the middle end of the grid power, improving the reliability of home power supply.
For the grid group, the rapid increase in the proportion of VRE (Volatile Renewable Energy) will further widen the difference between the power generation curve and the power consumption curve. Configuring energy storage can transfer power in time to help the grid balance power generation capacity and power demand.
Take home storage as an example, the graph below is Economic Calculation of Major Home Reserve Countries in the World
