FAQ
Q: Areyou manufacturer? A: Yes, we are. You are warmly welcome to visit our factory if you have interest!
Q: Could you provide a solution for our grid battery storge developments in our country? A: Yes, we can. What's more, our R&D team aims to provide full solution of battery system for ups power supply, solar storage,grid developments, medical equipments, LED lighting, e-bikes, consumer electronics, portable power banks, hand-held Terminaldevices, etc.
Q: Is OEM/ODM available? A: Yes, it is. Please feel free to tell us your application and your basic battery requirements. Our R&D team will provide a full solution to your with these factors taken into consideration: working temperature, dimension,compound mode, power, capacity, peak current, PCM, fuse, motion control ICs, plug, etc.
Q: Can you provide samples for testing use? A: Yes, we can. After discousion and designing with our sales and engineer, we encourage client to order samples first to test ourbattery quality and stability first.
Q: What’s the differences between li-ion cylindrical battery and Lithium polymer pouch cell? Which one is better? A: Li-ion cylindrical battery18650 battery cells can be easily assemblied to large capacity batttery pack or individually used forconsumer electronics etc.Lithium polymer pouch cell Lithium polymer battery has higher safety factor. It can be designed into ultra thin battery(paperbattery) or anti-low/high-temperature battery. Each type has different merits.
Q: What safety protection function does the PCM have? A: Short circuit protection, over-current protection,over-load protection, over-discharge protection, inversely-connection protection, temperature control, balance, fuse, thermistor, etc. Our engineer will choose particular function to use for your battery pack in accordance with your specific situation.
Q: Are there related certificates about battery? A: If required, we could apply CE, ROHS, CB(IEC62133), UL, KC, PSE, BIS, UN38.3 etc.
Q: How long for the warranty? A: Usually 1 - 3 year.
Q: Which payment methods do you accept? A: Usually, we will do Western Union, TT, LC .etc.
