Nanolongrange with 21700 Li-Ion battery

- Here is a short video on how I build a 1s 21700 battery for a Nanolongrange FPV drone. I prefer spot welding over soldering, it is way more robust. Compared to 18650 you will get a slightly longer flight time. In the last third of your flight you will experience a stronger decrease in performance as the weight of the bigger cell makes the drone about 20% heavier.
on. unboxi...
I lost about 300mAh trying to get a GPS fix, so you can get close to 25min flight time.
Hallo. What Drone is this? Is it comparable with Tinyhawk 2 freestyle? Thanks
It's my own 3d printed design www.thingiverse.com/thing:4818009 You need 1s suited parts to build it.
That is the model of motors and esc?
If you use acid flux instead of rosin flux it will allow you to solder directly to the cell without the nickel strip. Just wipe off with a wet rag to remove excess flux after soldering.
thanks for the tip!
I use a TS-100 style soldering station with soldering acid and it allows me to create very strong shiny joints literally in the matter of a second, so there's no thermal damage. Those connections are far more durable than spot welds. I've heard people lost their RC airplanes to spot welded packs, because the welds would just fall off.

what would happen if you ran 2 or 4 in series? Any advantages despite the weight or to much weight?
way too heavy. 2 in parallel would probably work on a 12A aio board.
What FC esc?
Hello awesome video and great work. May I ask what spot welder you used? Homemade ? Thank you!
it's a cheap China made spot welder. You ll find it for around 15$ online
You did nice job by adding a piece of nickel, cause as you know it takes much time to solder on the cell directly & it may degrade the mah of the cell, anyway nice video bro 👍 and by the way you almost run the drone for 5min even the battery drops to 3.08v and it stopped indicating, what is cutoff voltage of your mini drone? I'm so curious on this stuff Haha.. 😂
I've tested it down to 2.8V. The step up module is supposed to shut off at 2.65V. Not sure at which voltage the FC will give up.
is that 2 inch quad ? or 85mm ? may we know the spec of the quad you used in this video ?

Can't run digi on that?
sure, walksnail works best czcams.com/video/aQSzI7OpGfQ/video.html
18650 usually are more energy efficient., but not sure if there are there any better efficient 21700 wh/kg on market?
I bought the Samsung 40T because it has crazy high discharge rates: 35A continuous, 75A burst. The first 10min are giving you a Lipo-like stick feeling. Samsung 50E provide 5000mAh (+25%) but only 10A discharge rate.
@@Unboxingexperience7 Would Nitecore NL2150HP 21700 be more suitable? It has also 5000mAh, but at 15A discharge.
15A continuous should fit. Just don't expect a powerful quad
@@Unboxingexperience7 thanks
Qual kv tio?
11500
have you tried the new rekon35? made by the same guy but its a 3.5 inch quad with a dual battery cradle.
id love to see you try and replace the 18650 dual cradle with a 21700 dual cradle and do an endurance test. if you can get 25 minutes with this quad im thinking you can get 35+ with that setup.
no, I like to build and design my own stuff. I prefer 1s stuff but I may give 2s a try.
Das a big battery
This is puzzling. You can get a 3500mah 18650, why even go with a 21700 that’s 4000mah. Smh
the have 10a 5000mah now
You're not going to be flying with a 3500mah 18650
@@maximuschapman7760why though?
Because above 3000 mAh capacity sacrifices discharge rate
