FAQ and Answers :
Q. Can you explain in detail how you match cells for a battery pack before you assembling the pack?
A: We will do the following things before assembling the pack:
a. Select capacity, same capacities cells for one pack
b. Measure the voltage, same voltage cells for one pack(difference is under 0.02v per cell)
c. Measure the inner resistance,same IR cells for one pack (difference is under 1m Ohm)
All above steps are very strict to make sure the pack performance is perfect.
Q:What&rsquos your advantage compared with other suppliers?
A: a. High quality batteries: Our batteries are in enough capacity, and lower in RI,
Before shipment, we will inspect the products and ensure the quality which are well approved by our clients.
b. Better service: We always offer what our clients need. Reply client&rsquos questions timely. Supply best projects solution for clients. We ship out the products on time&hellip
Q: What&rsquos you payment and delivery items?
A: Payment items: By T/T, 30% for deposit, and balance all before shipment. For small
amount, we also accept payment via PayPal.
Q: What company will be used for making the shipments? DHL? UPS or others?
A:Normally, we ship our battery via TNT,UPS and FedEx, DHL. We also have some special line of special countries like US, Africa, India, Korea, Japen, Malaysia and so on. Pls contact us for details.
Q:How long can I store it?
A: To ensure the long-term (more than a month) storage battery, you need to follow some simple rules: Transfer to battery-storage mode (3,8 V-3, 9V);
Q:Do the operating lithium-polymer battery-zero temperatures?
A: In the battery, during the recoil energy, chemical reactions take place. When operating in sub-zero temperatures, the process is slowed down, the consequence is a decrease battery performance. When used in temperatures above zero, features restored to working values.
Q:How many cycles of the life of lithium-polymer batteries?
A:There is no single answer to this question is no. Battery lifetime depends on how well she enjoyed. We can not allow a full battery discharge, over-charge, and charge higher current than specified by the manufacturer. If you do not violate the manufacturer's recommendations and rules of operation, the number of cycles of charge discharge will be at least 500 over the life of the battery.
