18650 protected battery specifications

Ideal for all applications but the cell will show its true greatness in ultra high drain devices. While all lithium ion batteries are safe when cared for properly, the Samsung 20S is considered one of the safest options. The CDR of 30A is the highest true rating among all lithium ion batteries and it has tested to maintain a low running temperature at up to 40A CDR. This high current rating does come with a cost as the Samsung 20S has a capacity of only mAh so you will find yourself charging these batteries more often.

Everything You Need to Know about 18650 Batteries

The Samsung 25R remains our top seller for and it's easy to understand why. This has been the go to battery for many vape users since being released in With a capacity of mAh and CDR of 20A, this battery provides a great balance of current rating and capacity. During testing, this battery has surpasses its rating of 15A and all while giving you mAh of capacity.

It maintains a higher voltage output than most throughout the entirety of its cycle but not quite as high as the Sony VTC5A. It does offer a higher capacity and a lower cost than the VTC5A which is why we have rated the Samsung 30Q as our best value of This battery is powering electric vehicles, electric bikes, power tools and so many more applications.

It has great reliability with a mAh capacity and 4. Truly, one of the best batteries on the market! The first thing to consider when choosing an battery for your device or project is the battery brand.

Not all brands are created equal and often times you will find are not very truthful in their battery ratings. This is especially true when discussing the Chinese re-wrapping brands.

The goal of any manufacturer or brand is to sell as many batteries as possible but some companies have been known to exaggerate their ratings to appear to offer a better product than the other.

This practice of exaggerating battery specs is unlawful and can be very dangerous to consumers if gone unchecked. Thankfully, there is a watchdog in the lithium ion battery industry known as the battery mooch who provides thorough testing and will call out these companies for their unlawful practice.

These brands are well established and have long standing tradition, values and standard to uphold. Any manufacturer specs provided by these brands is well documented and tested many times over. You will often see the battery outperform the manufacturer ratings put forward from these brands.The main reason for this battery being successful is its properties compared to its competitors.

These properties include current carrying capability, voltage, cycle life, storage life, safety, and operating temperature and much more. Below table shows the comparison between popular batteries for key parameters. While working with batteries, the two most common terms you will come across is the mAh rating and the C rating.

An cell rated at mAh means that when we consume 2. C rating for a battery is usually 1C, this means that we can consume a maximum of 2. For instance if the C rating for our battery had been 0. The Cell belongs to the Lithium Ion type chemistry and hence very high care has to be taken while using it.

This includes while both charging and discharging the batteries. While discharging the batterycare should be taken that we never consume more current the C rating and also the battery should never be discharged below 3. Normally a circuit will be employed to monitor the discharge current and under voltage value to cut off the battery from the load if anything goes wrong.

Also care should be taken that the battery never experiences a short circuit or reverse polarity. If you are using a single cell then a battery protection module like TP is highly recommended to charge and discharge these module safely.

The charging voltage of cell is 4. Again a module like TP will come in very handy to charge this module and will also provide protection while discharging. Normally to achieve higher level of voltages more than one cells will be connected in series or parallel in that case care should be taken that all the cells are maintained in the same voltage levels, this process is called as cell balancing and is usually done using a BMS Battery management system which takes the responsibility of charging and discharging the batteries uniformly.

Have no fear! So what exactly is an battery?

18650 protected battery specifications

This naming convention refers to a lithium ion battery cell that is 18 mm in diameter, 65 mm in length and circular in shape.

As technology has advanced over the years, and especially in the past decade, the need for batteries which can keep up with modern gadgets has led to the development of cells capable of longer runtimes, higher outputs and better charging abilities. One of those developments is the introduction of li-ion batteries which were originally used in laptops. Like most technologies, engineers began looking for other applications for the battery and two industries quickly seized the opportunity: vaping and flashlights.

Nowadays, you can find batteries in a plethora of products from chainsaws and scooters to even a Tesla Model X. Although some basic things such as the internal chemistry and size remains consistent between s, there are a few options to be aware of.

The first and most important specification to pay attention to when buying batteries for your device is whether or not it requires a button-top cell. All NITECORE flashlights require this added protective circuit which not only provide an overall safer experience, but the added length is what creates a solid connection inside your flashlight. If you recall from high school physics, voltage measures the strength of an electrical charge.

Most batteries will have a voltage rating of 3. However, to measure how much of a charge is flowing at any time, we use the max discharge rate which is measured in Amps. Why does this matter? In order to get some of the brightest outputs possible, some flashlights require a higher discharge rate than is normal on a button-top For example, all of our single flashlights rated for lumens will need a battery with a max discharge rate of 8A or greater.

This specification is less important than the first two, but still one that can create a world of difference. Measured in milliamp hours, the capacity of the battery will help you gauge the overall runtime possible on your flashlight or device. The larger the capacity, the more runtime you can get. Our batteries range from mAh to mAh which is the highest capacity currently possible.

As you can imagine, over time more and more customized models have been designed to suit different applications.
