Let us explain how to properly analyze battery data from the perspective of a battery manufacturer.
The most important data for battery performance are: ① Continuous discharge current, ② Mid-Voltage discharge voltage, ③ Discharged capacity and ④ Smoothness of discharging curve.
1. The size of the sustainable discharge current;
When the battery is fully charged at 4.2v, if it can sustain the same current until it is discharged to 3.0v, and complete about 95% of the capacity discharge, then it is the true sustainable discharge performance. Please pay attention to the two factors that determine this performance: the current size and the actual capacity of the battery that can be discharged by about 95%.
Example: AULINE 850MAH 80C battery, can sustain a discharge of 60C (51A) and instantaneously discharge 80C (68A). When discharged from 4.2v to 3.0v, it can discharge about 94%-95% of the capacity (799MAH-807.5MAH). Only under these two conditions can it be said that the true performance of this battery is "sustainable discharge of 60C".
Example: A certain brand 850MAH 80C battery, labeled as 80C instantaneous 160C, when tested with our continuous discharge of 60C (51A) standard, the actual capacity discharged from 4.2v to 3.0v is only 40-45% of the labeled capacity (340MAH-382.5MAH), which indicates that the battery information is seriously exaggerated and does not match the actual battery information.
2. Discharge median voltage;
This data is an important value for us to judge battery performance. This value refers to the voltage of the battery when the median value is set during the total duration of continuous discharge current. Understanding the discharge median voltage can quickly determine the average discharge power of the battery, which is the discharge median voltage value multiplied by the continuous discharge current equals the average discharge power.
It can effectively help customers choose the battery that suits them.
For example, AULINE 850MAH 80C battery, the continuous discharge time of 60C (51A) is 1 minute and 2 seconds, and the median voltage is 3.3857V. That is, when the battery is tested with a continuous discharge of 60C (51A) for 31 seconds, the voltage of the battery is 3.3857V, and the average discharge power is 3.3857V*51A=172.67wH.
3. Discharge capacity;
Generally, the battery capacity we fill in is the capacity obtained by discharging at a constant current of 1C or 0.5C from 4.2V to 3.0V. For high-rate lithium batteries, the larger the capacity that can be discharged under the test standard conditions, the better the battery performance.
For example, AULINE 850MAH 80C battery can sustain a discharge of 60C (51A) and an instant discharge of 80C (68A). From full charge of 4.2V to 3.0V, it can discharge 94%-95% capacity (799MAH-807.5MAH).
For a certain brand of 850MAH 80C battery, the label shows an instant 160C discharge at 80C. Tested under our continuous discharge of 60C (51A), the actual discharge capacity from 4.2V to 3.0V is only 40-45% of the labeled capacity (340MAH-382.5MAH).
Therefore, under the same capacity and test conditions, the larger the capacity that can be discharged, the better the performance. The closer it is to the information displayed on the label, the better the battery performance without false labeling.
4. Discharge curve;
We use professional battery testing equipment to test the battery, and we will get a discharge curve (a curve in which the battery voltage decreases continuously according to the discharge time). If the discharge curve shows a stable downward trend, it indicates that the battery has stable discharge and excellent discharge performance. If there are spikes or ups and downs, it indicates poor battery discharge performance.
Summary:
Based on the continuous discharge results of the battery, analyzing the discharge capacity, median voltage, and discharge curve is the most accurate way to judge the actual discharge performance of the battery.
AULINE will continue to upload more real battery test discharge charts and results, allowing customers to better understand the true performance of our products.
Currently, we have uploaded the real discharge test charts for the AULINE A45 21700 4000MAH 45A battery and UAV series 16000MAH 20C battery. Please feel free check the page.

Thank you for reading this blog,
Since the release of our product BB4831 4800MAH 3S built-in Low Power Buzzer Alert and LED Indicator, we have received a lot of customer support and feedback, thank you all first we appreciate it.
At the same time, there are some problems about the product make customer feel confused, it is our bad, we have not fully introduced the advantages and disadvantages of the product.
In order to let customers know more about the product, we have selected one question which customers are more concerned about to answer.
Why is the internal resistance of one cells of the battery much different from the other two cells?
Answer: This is caused by the special assembly method of the battery, we use one piece 70mm length Nickel at the battery.
Generally we assemble batteries, we use wires to weld directly to the positive and negative electrodes of the battery (no Nickel between battery cells ),
When we assembled the battery BB4831, we used a 70mm length Nickel to link the first negative pole of the battery pack, and the first negative wire of the balance line was welded to this 70mm long Nickel, so when measuring the internal resistance of this batter pack, the resistance of the Nickel will be measured also what lead one of the cells show a higher internal resistance.
Hope our reply could help you understanding BB4831 a little more.
Thank you.
]]>Thank you visit our new blog, we appreciat it.

]]>Sum-up:
LiPo battery has much advantage than Li-on battery on Discharge power. High to 120C discharge rate, it’s like one big Turbo engines to your Drones/Tools. Premise on the same capacity,LiPo Battery was at disadvantage,more bigger cubage and almost double weight than normal Li-on battery. LiPo Battery was good at Drones/Tools and others, Li-on battery was good at support power to Mini tools/ Mini Electrical appliances.
]]>Thanks for reading this post, there we have released 2 type exclusive things at market.
Hope you like it.
The first one is BB4831 - 2170 Li-on 4800MAH 3S 11.1V XT60
It's more like one mini power tank.
What we did and make it special?
1, Pleastic Injection molding: in order to make it looks good and set Buzzer at right situation we made one gap for it.
2, Low Voltage Alert: It's different with Protection Board what's we used at A2641 which is for DJI FPV Goggles, when the voltage low to around 12v that lead protection board cut off power directly, it's a nightmare for us when we flying you know. Our new Low Voltage Alert will not let it happen, it's like one alarm just remaind you it's time flying back. It will not cut any power.
3, Voltage LED Indicator: You can see the capcaity situation any time you want just need click the switch (Yellow Point) of it. More intuitive to know its situation.
The second one is SS-EXT-16 Super Soft Power Supply Cable
It transform XT60 to DC5521, xt60 connector is special re-designed also, more bigger and stronger.
We tried 5 type materials of wire just want make it more soft. Finally we choose Nylon weaving thread, the best combine with Silicone wire.
#24 Silicone wire is avaliable load voltage 600 and current 2a.
Let's see what can them do,
Hope you will like it,
Have a good day.

This is because the Built-in Protection Board needed activated before use.
(all Auline products which built-in protector board are activated before leaving the factory).
2. How to Active the Protection Board?
Auline 3000mAh 3S for TBS CrossFire V2 Transmit as an example
Use DC 12.6v power supply contact Battery Discharge Connector for 1 second, and then you can use it normally.
3. What is the protection voltage we set?
2.8v per cells.
4. When the voltage down to 8.4v (Auline 3000mAH 3S for TBS CF Transmit) what will happen?
When your pack's voltage down to 8.4v that will active Protection Board work,
It will shut down and protect the battery pack.
When you are going to charge your pack, you need Re-active the protection board with DC 12.6v Power.
5. How to active Built-in Protection Board of 1S 2S 3S 5S 6S Battery Pack?
Same way to active the Protection Board like above, prepare DC power to connect Discharge Connector with following voltage:
1S_DC 4.20v Power supply.
2S_DC 8.40v Power supply.
3S_DC 12.6v Power supply.
4S_DC 16.8v Power supply.
5S_DC 21.0v Power supply.
6S_DC 25.2v Power supply.
6. Do we need re-active the Protection Board every time before we charge it?
It's unnecessary, only the voltage down to 8.4v (3S) it will active Protection Board protect battery pack.
So we would love suggest Pilots go to charge the battery pack before 8.6v (3S).
]]>I am Jerry from Auline Innovation LTD.
We have released many new packs at FPV market, include LiPo and Lion Pack.
We received many good sound and complain sounds also. Especial the problem with 2600mah 4S 18650 Pack for DJI Goggle.
Two customer met same problem the Solder Point was Broken:
As new brand at FPV market, that make us so nervous.
But we find it out immediately and complete the Resolvent.
We changed Solder Direction in order to change Force Point (see picture)
TThat will help a lots reduce force strength of solder point and avoid the problem happen again.
We are young brand at FPV market, but we will grow up fast with your help.
We are not afraid Products got problems, we always find it out and improve our products to a new level.
Hope we could get forgive and more support from that two customer who's battery got problem.
Sincerely,
Jerry
