What is the current largest capacity 21700 cell right now?

Vapcell F60 (FEB mah) is the highest capacity on the market currently (not the Samsung 50S, Samsung even sells a higher capacity one themselves, the 53G mah).

Vapcell has been getting a lot of the newest cell tech to consumers by rebranding cells from other brands and selling them in retailers. They have the F56, F58, G58, F60, which has been independently tested to reach those respective capacities. They have the N38 and N40 cells as well which are the highest capacity cells on the market.

Do note that for high-drain applications you'll be better off with something with lower resistance. Also think the F58 and F60 cells are better quality than the cells, so would opt for those. There's the LG M58T as well but that only gets around mah from what I've seen and is fairly high resistance, seems like an overall worse cell than the Vapcell F58/F60. BAK has a mah cell as well. Pajda has probably the best testing for these cells available currently right here on endless sphere so would look at that.

Cycle life tests of High Energy density cylindrical cells

Yes, you got me :) Maybe such small explanation on table jpg? Which is already travelling through internet alone and some people will be confused ;) Thanks

The availability to buy them is of course important too as we always read about these great inventions never making it past the news.

My plan is also to have the battery removable so to say make use of the most capacity cells as well as having the most ah in the pack to make the day. It is of crucial importance to save my sweet time.

Time is money for me. So I'm trying to figure out which cells to use. Earlier Samsung 40T may have had some problems, my guesses from my sources and if it is the same chemistry as the 30Q I think I'm not really happy with that quality or the uncertainity of it.

F38 had min capacity of mah and the N40 was specced min. cap of mah from a quick search. Source and sourcing I had a custom triangle pack of Samsung 40t 20s6p so 24ah. No I had it made at bicycle motor works. By Matt. It never got over 19ah. Plus I had to send it back because a whole series of cells had to be replaced at this point he put a Bluetooth BMS on. Never used over 80 amps.
So did he get counterfeit cells.
So it's very important where you inquire your cells from. Oh 1,200usd. Next time I need a battery I'm going to get a spot welder. As far as sizing a pack of these cells, they advertise 3C, but no way in hell would you want to run them in that condition.
1C is still pretty saggy, at 0.5C, finally we start to get liveable voltage drop ( more voltage drop = less battery efficiency and more heat ).

Notice that the line ends early, meaning we either overheated, or the voltage sag got too intense and we tripped LVC, from 10A to 20A. So this range is basically unusable, and possibly dangerous without liquid cooling if sustained for a high period of time.

These would be a very good choice for a bike with a big range, and low to medium level power requirements.
For example if you are running 20A but also have about 20AH of battery ( 1C )

As the demand for high-capacity batteries continues to rise,  battery cells have emerged as a popular choice for various applications, from electric vehicles (EVs) to power tools and consumer electronics. This comprehensive buying guide will help you navigate the key features, benefits, and considerations when selecting the best battery cells in .

What is a Battery?

The  battery is a cylindrical lithium-ion cell that measures 21mm in diameter and 70mm in length. It offers higher capacity and energy density than its predecessor, the  battery, making it suitable for high-drain devices. Typical capacities range from mAh to mAh, providing extended run times for various applications.

Advantages of Batteries

• Higher Capacity: With increased energy storage capabilities, batteries can power devices longer between charges.
• Improved Discharge Rates: They are designed to handle higher discharge currents, making them ideal for power-hungry applications.
• Versatility: Suitable for a wide range of uses, including electric vehicles, power tools, vaping devices, and more.

Key Features to Consider When Buying Batteries

1. Capacity (mAh):
   • Choose a battery with an appropriate capacity for your needs. Higher capacities (e.g., mAh) are better for devices requiring extended use without frequent recharging.
2. Discharge Rate (A):
   • Look at the continuous discharge rate, which indicates how much current the battery can deliver safely. For high-drain applications, opt for batteries with discharge rates of 30A or more.
3. Cycle Life:
   • The number of charge-discharge cycles a battery can undergo before its capacity significantly degrades is crucial. Aim for batteries with a cycle life of at least 300-800 cycles.
4. Voltage Rating:
   • Most batteries have a nominal voltage of 3.6V, with a maximum charge voltage of about 4.2V. Ensure compatibility with your device’s voltage requirements.
5. Brand Reputation:
   • Consider purchasing from reputable manufacturers known for quality and reliability. Brands like Samsung, Sony, LG, and Molicel are well-regarded in the industry.
