Precautions

1,No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.2,Customers should configure a BMS which is used for strictly monitoring, management and protection. 3,Properly connect the terminals of positive and negative of the batteries. The reversal charging is forbidden. If the polarity is reversed, the battery will be damaged and safety problem may occur.4,If the batteries kept unused for a long time, it should be charged and discharged at the standard model every six months. Store the battery in the state of 30% SOC (voltage scope: 3.275V~3.305V).5,AppearanceWithout break,distortion, contamination,leakage.

Very Important! About delivery and transportation Time&Please note: we do not accept the dispute of no update logistics!

1,Because the battery (especially the high-power battery you purchased) is a special commodity, the terms of transportation are very strict, all logistics companies in China, including China Post, UPS, FedEx, DHL, are unable to directly transport electricity Pool, 2,So we will start to transport your order from Hong Kong. Once the battery arrives in Europe or US, we will declare for import at the European or US customs. When the battery passes through the European or US customs, we will send it to you by UPS or FedEx. so the ups number we provide will not be updated before the battery passes the customs. This is normal. 3,Once UPS's transportation number is updated, you can receive the goods within 3-5 days at most. If we can't find the updated information after delivery, and the transportation time is still within the time we promised, please don't bring up a dispute.

Q:Can you test each battery PRIOR to shipping?

A:We will test all the battery Voltage and Internal resistance before shipping.Voltage:The deviation less than 0.01VResistance:The deviation less than 0.1mΩ

Q:How can I do if I need more help for the order?

A:Beauty customer service is online 24 hours, please contact customer service if you have any needs

Q:If I want to solar charge LiFePO4/Lithium Ion battery, which already has PCB, would a normal controller work fine?

A: For LiFePO4 / Lithium Ion battery, we always recommend to use LiFePO4/Lithium Ion solar controller. Especially if you are using the battery as UPS (back up power supply). The Lead Acid solar controller will constantly provide pulse current to the battery, in the long run, it might damage the PCB. So the PCB won't be able to protect the battery when it should be.

Q：I am a distributor. Can I cooperate with battery warehouse for a long time?

A: Yes,Individual pricing for large scale projects and wholesale demands is available.
