FAQs
Below you will find the answers to the common questions.
| 1 - General |
| 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. For example, if we series circuit two batteries with 12V, that will be 24 voltage in total. |
| Q: What are the advantages of lithium batteries? |
| A: High Energy Density: Electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need to batteries with a much higher energy density. In addition to this, there are many power applications from power tools to electric vehicles. The much higher power density offered by lithium ion batteries is a distinct advantage. Electric vehicles also need a battery technology that has a high energy density. Self-Discharge: Lithium ion cells is that their rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms. It is typically around 5% in the first 4 hours after being charged but then falls to around 1 or 2% per month. Low Maintenance: One major lithium ion battery advantage is that they do not require and maintenance to ensure their performance. Ni-Cad cells required a periodic discharge to ensure that they did not exhibit the memory effect. As this does not affect lithium ion cells, this process or other similar maintenance procedures are not required. No requirement for priming: Some rechargeable cells need to be primed when they receive their first charge. There is no requirement for this with lithium ion cells and batteries. Variety of types available: There are several types of lithium ion cell available. This advantage of lithium ion batteries can mean that the right technology can be used for the particular application needed. Some forms of lithium ion battery provide a high current density and are ideal for consumer mobile electronic equipment. Others are able to provide much higher current levels and are ideal for power tools and electric vehicles. |
| 2 - LiPO Battery |
| 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. ALL IN ONE 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: How does a LiPo battery work at high temperatures? |
| A: The high C-rate LIPO battery provides higher discharge rate of up to 60C, and better stability, controlled within 65°C to prevent overheating and damage; |
| Q: What does the C rate stand for in the battery industry? |
| A: The C rate is representative of the charge and discharge capability of the lithium-ion polymer battery. The C rate is divided into a discharge rate and a charge rate, and "C" is used to indicate the ratio of the charge and discharge current of the battery, that is the rate. For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of the 1200 mAh battery), and 1 C means 1200 mA (1 times rate of the 1200 mAh battery). Normally high discharge rate batteries can be fast-charged. |
| 3 - Shaped Battery |
| Q: Can shaped batteries support fast charge? |
| A: Yes, we're using advanced stacking technology and it can support fast charge and discharge. |
| Q: Can shape batteries be used in a low-temperature environment or high-temperature environment? |
| A: Currently, our shape batteries can be used at temperature -50 ℃~50 ℃ or 20 ℃~80 ℃. If you need anything different from this range, please send us more details for evaluation. |
| 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 be 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:

| 4 - LiFePO4 |
| 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 ALL IN ONE'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 certification. 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. |
| 5 - Low Temperature Battery |
| 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: ALL IN ONE 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. |
