Hello, I am a technician from Jiangxi Foster New Energy Group, and I will tell you from a professional point of view
To build electric vehicles, there is no than 18650 batteries in the world. the other three are rarely used, and there are almost no electric cartoons on the market.
Our company's brand is Yangtze River. For example, the 18650 model is divided into digital and electric types, and electric vehicles are all powered. by this, the most commonly used batteries are those with a power of 2000 mah and a power of 2500 mah. Assemble it yourself and see what voltage and capacity you want, and I'll give you a quote.
The Baguang 26650 rechargeable lithium battery on Taobao has a nominal capacity of 5300mah. What is the quality of this battery and if the capacity is seriously wrong?
It's is the case. completely impossible, the name The battery5-digit must be a rechargeable lithium battery. The first two numbers are the diameter and the last three numbers are the length. The unit is mm. The diameter of 18650 is 18mm and the length is 650mm. The length of the 26650 is the same, but the diameter is 26mm. The 18650 is 8mm thicker. Your 18650 flashlight should have a thin body. How can you fit such a thick battery in there?
The opposite is possible. Thin batteries can be installed in a thick body. There is an adapter body that can thicken the 18650 battery and install it into a 26650 flashlight. I guess you are asking because the battery life of the flashlight is not good and the brightness maximum cannot be used for more than a few hours. It is very likely that there is a problem with the battery you purchased. The best 18650 is currently the Panasonic 3100mAh, followed by the Sanyo2600mAh. Those with nominal numbers of 3800 and 4200 are all misleading, and some aren't even 2000mAh. You get what you pay for. If you search for 18650 batteries on Taobao and then rank them by sales volume, those priced below 20 yuan will not meet your requirements. Sanyo products priced around 20 yuan are all battery cells if you use them without. Be careful, they will be damaged. Those who are serious about making high-brightness flashlight batteries will point out that they have a protection circuit, which involves sealing a small circuit board into the negative electrode. Product details will usually give a photo. of the printed circuit. The price of this type of Sanyo is generally between 25 and 30 yuan, that of Panasonic is about 10 yuan more expensive. Sanyo 2600mAh is said to be used on 10W T6 flashlight, and the max brightnessmale can last 150 minutes. If you use the 3W Q5, it is estimated that 4 hours will be no problem.
The capacity of 26650 currently cannot reach 5300mAh
The capacity of 32650 can reach 5000, and the capacity of 26650 is currently 3500, this which is the biggest
I have never heard of the brand you mentioned. I have been in the lithium battery industry for ten years. If it's a big brand, I know it.
