1 Battery, 1 Hour of Flight

by MyGeekShow | November 16, 2014 | (6) Posted in Challenges

 

Can we fly an hour on just one battery? Lets find out!

This episode I'll put one of MyGeekShow's NCR18650B cells on the Raptor 100 and see if we can fly over 60 minutes on one charge. It will be a test of not only the airplane, but the pilot's ability to keep sane for the entire duration.

Safety Statement: To maintain safety, I prepared by doing many thing things including:
-obtaining personal permission from property owners
-maintained a continues watch for full scale aircraft, and;
-maintained direct control of the aircraft for the majority of the flight
-this airplane and system has OVER 1,000 MILES of perfect performance, with 90% of it autonomous with this exact set up. It has been tried and proven many, many times, including over 200km of cross country flights
-the autopilot was programmed to continue to fly after a signal loss, which has been tested and proven to perform many, many times
-the flight was over a very open and low populated area, with 99%+ of the area being open fields or trees
-the altitude may read over 120m, but elevation increased during flight as I took off out of a low valley. True AGL for the flight is 100-120m.
-avoided all airports and populated areas.
-I've flown at this location 3-5 times a week for the last year. I know it very, very well.
-I conducted test flights with the new set up that I did not show during the video to confirm stable performance

Well done. Will be watching the development of these batteries for RC applications. What are the Con's to this battery? Charge time, duty cycle? Thanks, Joe

They are amazing cells, but two things to keep in mind:
1- Cost, each cell is about $12 or so, so this pack retails at about $70
2- C rating, they have a 0.5C happy, a 2C max, and a burst 3C rating. You can't draw more than 7A off of a 4S1P pack for too long. Don't forget this is at 14.8v, so its "effective" 11.1v Amperage is 9A.

Also you may want to add that these are good for around 1000 cycles, which lipos are only around 100. The batteries you use have a high and low voltage protection, and there are vents pressure build up in the batteries. Also no Puffing. The set back is that it take longer to charge at lower Cs

I would like to know a lot more about the battery too. Like the charger that would be used with it and how long it takes to charge? Is there any trouble with if you discharge it down and things like that? Thanks Paul

It uses a standard charger, just set it to 4S (in my case) and you'll be fine! Check out https://www.youtube.com/watch?v=adfydRg8PYU for more details.

I am trying to get more flight time on my quad copter that currently has two 2200 3cell lipos on it and it only flys for 12 minutes before falling out of the sky. Would some of these packs help?

I think the C-rating on these cells are a lot lower than a quad would need.

I have used these type of batteries for my tricopter. Unfortunately his at the lower amp rating would not work for you unless you get a few of them. I have 3s2p LiIon packs (total of 6 cells at 5000mah 11.1v for 60amps

I have made 2s2p (8.4v 6400mah) packs with these batteries for 24hr mountain bike races and they are awesome. They are more expensive than Lipos but they have greater energy density. You do need to more careful of discharge rate as they weren't meant to be depleted in 10minutes like lipos but they are great for long flight like this. 18650 cells are primarily used in laptops but are also used in anything from flashlights to Tesla sports cars. Most hobby chargers like iMax B6 and better can charge them.

Awesome! That sounds like an awesome project! Agreed, they are endurance cells, not sprint cells.

This has grabbed my attention.

3 x 3 as 11.1v (3S) = 10200 mah - 18a discharge (40a burst) - 405g + weight for cables, maybe around 450g.

My quad could EASILY handle this setup. I hover at around 8-10 amps, and max throttle puts it around 20 amps. On 3S a 4000mah 400g battery I get flight times around 12-14 minutes when just cruising around. This could extend it out to 30 minutes or longer!

Am I wrong in figuring up my discharge rate?

Good question! For me, I make sure I have 1 pack for each 100 watts needed for cruise. So, if you're running a 40A burst at 11.1v, you're drawing 444w, so you'd need 4 of these packs to provide the performance you're familiar with. Keep this in mind though, with 4 packs you'd be carrying 13,600mah at 14.8v!! That's an impressive amount of power for the weight (2x as much power per gram of LiPo cells)

My thought is a single battery has a discharge rate of 2C, or roughly 6 amps, and a burst rate of 6C, or roughly 18 amps. With a 3 x 3 (9 batteries) pack, it would increase the discharge rate of those 3 combined battery packs to a total of 6C, or roughly 18 amps, at 11.1V (12.6v charged fully), correct?

Nevermind, I was misunderstanding the max amps isn't burst rate lol.

Panasonic does have high discharge 18650's that can handle 10A and burst of 18A but the density is a little less with 2900mah. Look for the NCR18650PF cells. Used mostly for modded E-cigs and crazy high output flashlights and now Simpson in his uber quad.

how much does your battery weigh? also what are the dimensions of the battery too?

artemen on November 17, 2014
Hi Trend, as much as those Panasonic cells are good, they are also quite expensive! Try out hobby king multistar series lipos. They are high density but only 10c discharge as a result they are much lighter than regular lipos. their 4s 4Ah pack without wires and plugs weight only 270g (320 with). I suggest using 18awg wires and xt30 connectors for a total weight of under 300g. These are perfect for long time FPV, but are useless for 3d flying.

Awesome. I had checked out your other videos a few weeks back and instead of throwing some old laptops away i ripped out the 18650's. Out of 3 laptops only 2 cells were bad. My plan is to use them for ground station or second battery on plane for fpv/camera system only. I compared a 3s setup (my 18650s are 2200) to my 2200 3s turnigy and it is almost half the weight like you said.
