Q: Why does a battery discharge time be shorted?
A:Normally the battery internal resistance will be increased with more use, then the battery discharge performance will be degraded, and voltage drops more fast, so the discharge time be shorted.
Q: What is the difference between parallel and series circuits?
A:Parallel circuit is involved two or more batteries connected to extend the capacity. In this case, the positive terminals are connected together, and the negative terminals are connected together until the desired capacity reached.
Series circuit connects two or more batteries together to increase the voltage. We connect the positive terminal to the negative one until reaching the voltage we need.
Q: What is the high C rate LiPO battery?
A:Normally if the battery C rate ≥5C, then this kind of battery be defined as high C rate LiPO battery. Grepow high discharge C rate LiPO battery can be discharged up to 60C continuously, and 200C pulse. What's more, such batteries can be fast charged via 5C.
Q: What are the applications of shaped batteries?
A: Wearable devices like Smart Watches, Smart Wristbands, Wireless Headphones, VR/AR headset;Medical Equipment, Various Consumer Electronics, Smart Cards, Heating Clothing, Tracking Devices, Smart Locks, GPS trackers, Smart Rings, IoT devices, portable consumer electronics and so on.
Q: What's the advantage of shape batteries comparing with other regular rectangle batteries?
A: The main advantage is to make full use of the internal space of devices and increase the running time.Q: What is the average battery life?
A: Generally, consumer wearable device's working current is within 0.5C, in this case, the battery life could be 1000 cycles. After 1000 cycles, the capacity maintained over 80%.Q: What shape can made?
A: Every shape is possible. The thickness between 0.4~8mm, width between 6~50mm Shaped battery has over 5,000 batteries in various chemistries, sizes, shapes, and capacities. The following types are references:Q: What certification does Grepow have?
A: Grepow has passed IS09001, ISO14001, TS16949, OHSAS18001 quality system certification, and our products can pass ROHS, CE, UL, UN38.3, MSDS and other certification.If you need any product certifications, please let us know and we can help to apply for the certification for you.
Q: Does the LiFePO4 battery have a memory effect?
A: LiFePO4 batteries do not have memory effect. That means deep-discharge cycles are not required. In fact, it's better for the battery via shallow discharge and charge cycles.Q: How many times does the promised cycle of Grepow's LiFePO4 battery reach?
A: Around 1500 times or three years of use, whichever comes first.Q: Can ship LiFePO4 batteries to the United States or other regions?
A: Yes, but if you need to ship the battery internationally, you need to get the relevant certificantion. For example, the battery transported by air to some regions (e.g. Unite State) must be UN38.3 certified, pass various safety tests to ensure the safe transportation of batteries.Q: Is the lithium iron phosphate battery dangerous?
A: LiFePO4 batteries are environmentally safe and structurally stable. They own excellent high temperature performance. The chemistry of the battery saves it from thermal runaway, and hence it is considered to be safe for home use.Q: What is the minimum charging temperature for low temperature batteries?
A:Can be charged at -20℃ (Minimum);
Q: What is the minimum discharge temperature?
A:The operating temperature range is between -50℃ to 55℃;The discharging capacity of 0.5C at -40℃ is over 60% of initial capacity; 0.3C at -35℃ is over 70% of initial capacity;
Q: What is the chemistry of the low temperature battery?
A:Grepow low temperature LiFePO4 battery takes new technology from long-term development, we add special functional materials into the electrolyte, the excellent technology can ensure the great low temperature discharge performance.
