Warning!!!!! Like the18650 flight packs these 21700 are not for everyone.
What is your purpose with these batteries? If you want to go fast and race, these batteries is not for you. But if you are able to manage your amp draw and fly for maximum flight time, this is perfect for you. Make sure you pick the correct 21700 cells that matches your applications. For me I am using: MOLICEL 21700 P42A 4200MAH 45A BATTERY

Check out my build page on how I used these batteries to get over 25 minutes of flight time on a 7" quads: https://rotorbuilds.com/build/22522
If you plan to build these pack yourself, I would suggest using a spot weld because it would reduce the risk of damaging the cells if you over heat it. Please look on youtube for proper handling of lithium ion batteries.
Update: I just added a 4s version for this battery holder.
Update 2025: Updated the 6s version that has all the parts in one plate because not all of the item was aligned to the bottom correctly.
Update 2025: Added 3s and 6s stacked in 3s configuration.
