1、Lipo battery FAQ and Answers关于RC-lipo电池的FAQ1. Q: knowledge for the Manufacturing process of the Lipo batteries:A: First from raw materials-drying-Balling-Mixing-Coating-Electrode drying-calendaring-cutting-punching-stackingtab welding-short circuit checking-pre-package-electrolyte injection-pre-form

2、ation-degassing-gas bag cutting-folding-code printing-formation-aging-finished products.2. Q: For example, I have heard people say that the Lipo batteries have a Production and an Expiration Date! Meaning that if the Lipo is Old”, it could be Not good and loose its potential really easy . Do you hap

3、pen to know anything about that?A: About the life of lipo packs, usually we suggest that our customers to storage the lipo packs in half full status under proper temperature environment for storage. And if you do not use them for about 3 or 6 months, we suggest re-charging the lipo packs for 1-3time

4、s during this period and then re-storage. And this is no problem for the performance and quality of the lipo packs when you re-start to use them.3. Q：What is the story with the weight? If two batteries on the same capacity and cell number have different weight, does that mean that the heavier one ha

5、s more Discharging capabilities (more C)?A：About weight, usually the exact capacity cells will also have a certain weight of the inside materials. If just under with real materials and also under the same dimension, of course the weight (as the materials is more) is higher, then capacity is good and

6、 also the discharge capability is better. But not higher weighter much better. As the RC models sometimes needs lower weight under the same lipo packs. So this will need higher production technology to make it.4. Q：Why are they inflating? Is it water vapors (moisture) thats building inside the cell?

7、A：About inflating, its not with water vapors. As for lipo batteries, the status of inside is like solid-state. So if the lipo pack inflating/swelling, thats due to over-charging or over-discharging which damaged the inside structure of the lipo packs materials, and caused the gas, which seems will b

8、e swelled.5. Q: I need Batteries witch can keep the 40C on 22 Celsius - is that possible?A: Itshard tokeep the 40C on 22 Celsius when you discharge the lipo pack with 40C.6. Q: What temperature gets your battery on a discharge rate from 40C and over 75% of the whole capacity?A：The temperaturefordisc

9、harge rate from 40C around 65-70 Celsius.7. Q：Can your battery keep the discharge rate of 40C over 75% of the whole capacity?A：No problem to keep the discharge rate of 40C over 75% of the whole capacity of our lipo packs.8. Q：Can you send me the picture of the packaging they come in?A: Please check

10、the picture ofour lipo batterypackaging pictures attached. (Usually we first usethe thickbubble foam to wrap the lipo packs every sides to avoid any crash or damage; and then we will make every battery pack tied and finally use a strong box to carry them. And will also use some hard plastics patches

11、 to fix the box.So please just take easy onthe package during the transportation. As we have also sent many cargos out to our customers all over theworld, which always in good status whenreached to our customers.Thanks.9. Q：The Lithium Polymer Cautions：A: Lithium Polymer Batteries and packs that are

12、 abused may cause damage to the pack or the device resulting in personal injury.Do not expose the battery to extreme heatDo not short circuit batteryDo not puncture or modify the battery or packDo not immerse the battery in waterNever reverse charge the batteryCharge only with charger specified by e

13、quipment manufacturerOperating temperatures for charging are 0 to 45 10. Q: I thought that your prices would be lower than those on the Hobbycity website. Everyone here in Italy uses this web site as a reference and I find it very hard to sell at prices that are above those.A: We know and understand

14、 that so far some customers always take the prices levels from hobbycity for reference and negotiate on prices offers from other suppliers. Also, hobbycity also indeed doing some harmful to some main and big distributors inthis RC markets. But considering the whole markets development and also brand

15、 reputation establishment, high stable quality and performance batteries with competitive prices will be the trend for the markets. And so far we are also planning to work out an effective way to compete with Hobbycity lipos to assist our customers to solid their market shares as possible we can. So

16、 maybe for some lipo packs items, the prices from Hobbycity is lower than ours, but for some other items, maybe we can also provide a much competitive offers for our customers. So could you please kindly re-check your demanded items and it will be much better and helpful if you can also list the prices you got from Hobbycity for our reference, and then we will check and provide the
