Reddit reviews Turnigy 2200mAh 3S 20C Lipo Pack

That print does look rather large to me though. Lets assume it took 20h. I've assumed an average power consumption of 62 W [1].

Thus, the total print would require 1240 Wh.

The most commonly sold RC battery on amazon.com offers 2200mAh at 11,1V which equals to 24,42 Wh per battery. [2] I'm pretty sure you can run a printer on 11,1V without a step-up converter. You would need 50 of those, and that is not going to fit the box that he packed at 0:23.

Every thermoelectric device I've seen consumes a pretty significant amount of power (~20W on one of the ones I've played with, which the one pictured looks very similar to). A LiPoly pack that can do that for an hour (with a suitable converter in between, I'm assuming ~80% efficiency) would need to be ~24Wh, for a 3-cell pack (nominal voltage 11.1V) this is ~2200mAh. Here is an example of a pack that can do that. The article also says they run it 5s on, 10s off, which would approximately triples that runtime to 3 hours (followed by ~4-5 hours charging, based on nearly identical packs I have for various things).


That said, the batteries shown in the article look more like a 2-cell pack of approximately 1100mAh (hard to guess though, since I can't see the pack fully), so they're either running much less power to the TECs than their upper limit, or they're not running it for very long (~1 hour).

So, it needs a decent sized battery, but if you only want to run it for a couple hours, it probably won't be too bad.

Those batteries are a little chunky for a 250. I have some and they are slightly bigger and heavier than my 2200mAh zippy compact but I like to fly 1500 zippy the best on mine. I got the 2206 motors on my h250cf 3k pro and just added 20a esc and 6040 props to it last night. It's a beast! I use that same charger and it's great. I say go with the 99$ kit h250cf pro kit.
I would also not recommended the flysky fs-t6 I was seeing brown outs with it and left negative review on Amazon for the product. I now use a taranis and it really is amazing! Here is my speed run this weekend. I need to tilt my fpv camera so I can go faster and see where I'm going. This isn't all she has by any means. This was warm up before I went tree cruising

OK, I need to clarify this.

When the motors are not firing balls, and as long as I have my finger on the trigger, the motors will run great, and not slow down. So they appear to be working great.

However, It's when they are shooting balls that there is a problem. When they are firing the balls for a solid 10-15 seconds, the motors start to slow down, and sound like the battery is dying.

The battery has a 20C constant rating with 30C burst discharge rate.

The battery I'm using is this one: https://www.amazon.com/gp/product/B0072AEY5I/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I'll admit that I'm having to read up on the C rating right now. I don't know much about that. Is a 20C battery too low? Or maybe it's just not made to be held down continuously?

Thanks again with all the help you've given me. It really means a lot.

  You'll also need some Dollar tree foam, some music wire, clear tape, razor blades, ect. That setup will get you started with tons of room to grow. The one transmitter will handle 8 planes at least.

Hello, I was just about to order a couple days ago, then figured I should ask you all here on /r/Multicopter if you have any recommendations for changes. I can solder and have tools, is there anything that I am missing here for a complete setup? Oh I also already own a Spektrum DX6i with two Spektrum AR610 receivers.

It seems that indeed we want to replicate the 'astronaut backpack' from your event company, though probably with a more Dr. Seus visual. Fortunately weight isn't much of an issue. We perform as a group so we can just rotate the backpack between performers. The "ideal" solution would be to use something like drill batteries so we could swap them out as needed. I really have no idea how much power a bubble machine would use relative to the energy stored in a car battery.

So to check if I'm reading this right

If we went with a SLA battery, which is a lot cheaper than a LiPo battery for the same amount of power, we'd need...

1. A SLA battery
   
2. An inverter that converts to 120v-60hz home voltage
   
3. The cabling between the battery and the inverter. This is the part I don't know how to do.
   
4. A battery charger for charging up the battery between gigs.
   
5. Additional: We'd probably need some sort of switch somewhere to turn the device on and off without unplugging it from the inverter.
   
   One other concern is that if the bubble machine is on a moving person, most bubble machines have a shallow resevoir and will slosh easily. How was the bubble astronaut setup?
   
   Edit: Also I'm trying to do electrical math for how long batteries last, and brain is melting a bit. So just using examples
   
   Bubble machine : http://amzn.com/B000LXTKMK
   Battery : http://amzn.com/B0072AEY5I
   
   The bubble machine draws 500 milliamps of power, which is .5 amp. The battery has 2200 mAh of power. So if I’m reading how it works correctly, it’s a matter of just dividing the milliamps of power into the mAh and you get about four hours of power. Is that right?
   
   

Thanks for the response! Which 1300mah batteries did you purchase?

I have a chunk of amazon credit that I'd like to use to get the rest of my stuff (even if it comes at a slight premium), so I plan on getting my prop balancer, charger, etc from there if possible.

This is the charger

And I'm considering a few of these batteries

I just burned out an ESC on a quad I just finished building :(. What's the best way to determine the cause?

It's a this ESC powered by this battery with this power distribution board. Thanks in advance!

Perfect!!! I decided to use that!

Can you let me know if you see any problems with this list?? Anything I can improve?? Anything I don't need??

Frame, PDB, FC, Motors, ESCs

Extra XT60 Battery Connectors

Props

Standoffs

2mm Gold Bullet Connector

Cable/Zip Ties

DIY FPV Kit

Tx/Rx

Tx/Rx to USB Adapter

Drone Battery 1 (heavy) 2200mAh

Drone Battery 2 (light) 1800mAh

FPV battery 1500mAh

What's the cheapest way to be able to get voltage to show on my FPV setup?

-Would I be able to use this voltage checker/warning buzzer?

What about a cheap lost model buzzer/discovery buzzer?? Can I use a switch on my Tx to make the alarm sound??

Is it overkill to get 3 batteries total?? 2 for the drone (So I can keep flying when one is charging) and 1 for the FPV reciever/display?

Thanks for the help!!

No idea how much they draw, but I'm using this 2200mAh 20C battery with no issues:

https://www.amazon.com/Turnigy-2200mAh-20C-Lipo-Pack/dp/B0072AEY5I/

Your diagram is exactly how I wired mine, only difference is I spliced together the negatives to save wire. Should be good to go.

I went with a Turnigy 2200mAh 3S 20C Lipo Pack for the controller with this charger and they are XT60


Could I use the same charger for the Quad packs? I have not pulled the trigger on the Turnigy nano-tech 1300mAh 3S 45/90 Lipo Pack yet.


I'm guessing the recommendation for the 1800mah 25-35C is to fly slower at first right? We would by flying FPV but not racing it so I think that's probably a good recommendation.

Since we are already using 2200mAh 3S 20C with an XT60 connector could we just use the same exact pack for the quad? It's rated at 20 constant, 30 burst and we could always use a spare for the controller if we go with a lighter battery with higher discharge for the quad later.

We aren't carrying a GoPro or anything so it would probably support the 2200.

Here's a GenAce battery that works too.
