😄.. I use 2 car batteries. One on each side so I don't get a bent neck. 😉 Of course it's in series.. Balance charging.😅

evrything Chad does is so easy to understand. He has a way of covering all the details. I really appreciate his taking the time to go the extra mile

I think one of my favorite things about the Rotor Riot guys is that they are honest and don't seem to be spokesman for their sponsors, they just tell it like it is. "These batteries suck." You would never hear that from most people talking about a product they are sponsored by or affiliated with. I'm glad these guys don't just act like all their gear is great without ever saying something negative. If all somebody has to say is good things all the time and can't find anything bad to say, they're either a liar, an idiot, or both and I wouldn't trust them. These guys are doing it right. Cheers to honesty!

the more they say "DON'T DO IT" the more I get the urge to do it.

My new favorite KZread channel just validated what I was thinking! I wanted an extra pack for my Quanum Cyclops FPV goggles, so I was sitting down to solder up some 18650s. I thought I'd check to see if someone else had headed down this road, and the Rotor Riot guys were the first result...delight! For folks with some gray in their hair (or beard), we did this a million times with NiCD/NiMH packs for electric RC car racing. As long as your soldering technique is good, all is well. Of course, LiPo is scarier because of it's tendency to discharge when overheated, but these cells are INR (lithium manganese nickel), which is quite a bit safer than LiPo for this application.

22:50 You finally mention the possibility of 3D printing your own Hardshell Case for these... Took a load off my heart =)

Those plastic cases that they 18650b come in actually make a better "case" than the heatshrink.

Does anybody know of a source for a generic LiPo battery level LED board like comes inside the FatShark battery?

When you use the multi-meter you should be taking the measurements from the red-white and white-black to see each cell voltage. If you think about it, its just the same as you would measure directly from an individual battery except the its through the balance lead. (The voltage checker doesn't actually subtract from the total 2s voltage) White is your 'neutral/reference', red positive and black negative. (BTW if you ran black-white you'd get a the right measurement but negative since your positive MM lead is on the black negative battery terminal). Hope this helps =]

PERFECT TIMING! just bought all the stuff to make these!

lol Sooo the Ice Cream truck fooled me... was looking around trying to figure why there was an ice cream truck driving around in the morning

Thanks for the vid, have made several packs before but not using 18650 cells. Now I have some sweet 2S3400 packs. Thanks for the inspiration! :)

Just use a 2 Cell 18650 battery holder so there is no need to solder onto the cells. Its a lot safer and it allows you to remove the cells and charge them individually with is safer. Also the 18650 battery holder will add more protection than heat shrink. Those particular Panasonic 18650B are rated at a genuine 3400mAh compared to the fatshark ones in the video that were either 1000mAh or 1700mAh. So these 18650's will double the battery life of the fatsharks newer 1700mAh. Nice video, Keep up the Great work. Happy Flying

Cheers for that guys. Might have been a good idea to mention that the 18650 cells charge at 0.2c and not 1C!

I guess it's person preference, but I don't understand why anyone runs the battery in the head strap or why they would even spend all the time to do this. Don't get me wrong, I liked the video and all, but why not just throw a 3000+mAh lipo in your pocket and make an extension lead with an XT60 connector on one end, and a barrel plug on the other end. Then you don't have to worry about bringing extra batteries, it's less weight pulling the goggles down on your face, and you can charge it with just about any charger.

Wow that heat shrink demo was amazing!

To clear it up for anyone who doesn’t get it. The cell checker measures full voltage, red to black, on the balance lead, then cell one, black to white, then cell two, white to white to red, to get each cells voltage without subtraction. Larger packs just measure along the balance connector in pairs moving along the connector one pin at a time. This is easily seen by probing the balance pins on a parallel charge board. When measuring cell one the white wire will be positive, and it will be negative checking cell two. That is why the DMM measurement didn’t match.

With regards to the balance port and reading voltages with a multimeter: Red to Black will give the voltage of the entire pack (7.4v) Red to White will give the voltage of the 1st cell (3.7v) White to Black will give the voltage of the 2nd cell (3.7v)

Very nice hack! I didn't even know these Panasonic batteries existed... Also using the solder wick to bridge is a nice idea.

Dear RR, will you test the Connex Prosight HD ? would be nice to see a Review from pros

One of the main reasons I was so excited when Kapper announced he was doing this show was because ummagawd was going to be one of the hosts. Glad to see he's being a bigger presence on the show!

Great video ! Thanks for these tips !

Hey guys, I very like your videos! A few weeks ago, you said it will be coming an episode about PID tuning. Is there anything planned? Will a video come soon?

I like how tommy said it was "rotor riot approved", but then says that we shouldn't do it. Haha.

Does this battery need to be brought to a storage voltage when storing?

was awesome meeting you guys at flitefest! :)

I'm not sure if you can still find them, but we used to use little battery bars to connect nihm and nicd batteries. they make a nice solid connection.

A parts list in the description would help A LOT!

Did anyone's else Siri get opened ? 😂😂

Looks great! The solder wick is a good idea but a larger solder wick needs to be used to handle the amperage in applications related to larger batteries. Make sure to keep the connection tight because; it might cause fraying and eventual failure. To keep down corrosion at the wick use battery terminal paste from an auto parts store.

Build something similar with a long cable to put the thing in my pocket. I'm wondering: you're using liion batteries, instead of lipos. Why is that? Is there a cheap alternative for the visual battery status checker? E.g. from banggood?

good hack, and another gr8 episode , some laptop batteries have these cells in and a dead pack will normaly only have one bad cell , thing to remember while you are not doing it at home :)

which charging rate do you use for this battery? the specs sheet says 0.5C (1625mA). Is it the same when we have them in series? Thanks.

So you bring 20 4s packs out to fly for the day... but you need to build a better battery for your goggles rather than bring extras? I dont get it. LOL

fatshark batteries are really expensive

You can get little plastic holders for 2 of these cells to fit in which you can do all the soldering on, then just push the cells in afterwards. Much safer. Just search Google or Ebay for "panasonic 18650b holder".

So basically FatShark took this idea and implemented them in the Transformer HD? Cool vid 😎

great informational video =) I did not do this at home and the results are good so far. Ill test my imaginary battery this weekend.

6:38 - Now I want ice cream

where do you get the purple rotor riot stickers? i cant find them in the store :/

The batteries are wired in series, so you just check the voltage between the points in the circuit! You can test the individual cell voltages with a multi meter by measuring like this: cell 1: negative - black wire positive - white wire cell 2: negative - white wire positive - red wire (and so on)

I just got a new FS battery case and did this mod. I was just wondering how well the Solder wick worked on the battery pack from this video?

wow... 18:25 made me start looking around to see if my phone had a message...

You can also pick the 18650 batteries up in almost any vape shop

And if you are scare of exploding your batteries when soldering stuff right into them, just buy those plastic battery cases that you normally put there things on and solder them together. Its exploding free and will work the same way and you can do it at home! Also you can carry extra batteries in your pocket and change them if needed. And if you are not familiar with C charging rates you can use normal 18650 battery chargers that don't cause you any trouble. Also if you have flashlights, bicycle lights vaping mods or anything else that use the same type of batteries you can use the same type of battery in all these devices. So when you are not flying you can pop out your batteries from your goggles and put them in your bicycle light. I have personally around 14 of those 18650 batteries and try to buy only products that use that type of batteries so I can swap them back and forth when ever needed.

"You don't want to heat these batteries up to much"......*Hot glues it then takes a heat gun to it*...."Remember dont do this at home" hahaha

Well at least Chad finally has a decent set of Fat Shark batteries now! :) Just my 2 cents, maybe Rotor Riot should sell a completed battery.. that will also help pay for lawyers for your lawsuit!

Where do you get the nice heat shrink and size? @FinalGlideAus

Does having the voltage checker board affect the impedance of the pack when checked using a smart charger?

So my background in R/C its very large, from flying tiny whoops to the racing in the GT12 Nationals, also building foam-core planes to 3D 50cc gaser, and even flying AP ships for films and racing 280's in an underground club. In total i have over 20 years in the R/C world, and id say that LiPo's have only been around 10 of those years. Before LiPo's came about, most of the R/C vehicles used NiMh/NiCd battery's, for me i built my own battery packs in this way, But used "Deans Battery Bars to connect them together. For me this project is a walk in the park, so i WILL be trying this at home, and don't worry, if a battery goes "POP", i Know what to do.

lol u guys are nuts thanks for the video awsome as always.

Thank you for this guys - very amusing ! ! ! - also very informative as I was wondering just how tolerant Lion cells are to the heat of a solllllllldering iron - thank you again all you expert solllllllderers !

Okay, I’m not saying I just completed one of these, but what I AM saying is that my new fatshark battery needs some branding now. Also, how many amps would YOU charge this with? 6.8, right?

18650 taranis battery mod! We demand rotor riot battery straps and Rotor riot radio lanyards!

when charging what should i charge it at? its a 2s and should icharge it as a lipo? and whats the capacity in mAh of this battery?

Fatshark packs are 1000mah for the small pack and 1800mah for the larger one. The Panasonic 18650s they are using look like the 3400mah ones, so that is 1.88x the battery life vs an 1800mah, and a 3.4x vs the 1000mah packs. The batteries right now are $13 shipped per pair on amazon. Charging: Panasonic (NCR18650B) cells are rated for .5c charging (half that if temperature is below 10c)

Hey guys, do you use voltage protected 18650s which include LVC circuitry on this? If not, do you see any problem with using batteries of that variety?

just made one, whats the proper way of charging it? i have an imax b6 lipo charger

Awesome guys! Those look alot like the batteries in my vape. Lol Great idea, I'm not confident enough in my soldering skills to not blow up. I may have a buddy that would do it. Lol

HELP! Can't do step one! I need to open up the case to add a balance connector in, my old one is completely done, I think the wire came out on the inside. How do I open the case? I've tried making the tab un-latch, but its just not working.

Great idea to build such a pack! I've been searching for the batteries and this specific NCR18650B battery doesn't pave a protection circuit buit in. There are versions with a protection circuit available. Would it be smart to use the protected batteries instead of the unprotected? Furthermore, the same batteries are available with solder pads which should be a lot safer than soldering the wires directly onto the battery.

+FinalGlideAus true.. :) i ordered both to test though and a holder for the batteries to avoid soldering directly onto the batteries.

how do you expect us not to do this? this is amazing.

So is it a 2.1mm barrel connector or a 2.5mm barrel connector? I have already been making these but with a jst connector- I mean, I won't be making these, just curious .>

The question Chad raised at 23:24... my theory is that the designers of the face plate fan knew this was going to retro fit other models of their goggles (and as it happens other makes too) , this method makes it easy to be powered, if you had to connect the face-plate to the inside of the goggles to get its power from it would be way more difficult.

what is a good fpv racer to start with that doesnt cost an arm and a leg......was thinking of getting the falcon 250

i have so many 18560 batteries at home, finally a use for them

Can someone advise? I have FatShark Dominator V3 Headset fitted with the LaForge FPV and diversity module. Nominal volts recommended by fatshark are no good, I have tested on a Lab PSU I have found above pulls 1amp and don’t seem to like going lower than 8v as the sharks start beeping to say the battery is low. If I pump up the volts to 8.5v they seem happy. What is the nominal recommended voltage and max load for running with above FatSharks LaForge FPV and diversity?

where can i find the balance conector and the jack cable? thanks!

Tommy drops battery pack on table...everyone looks down to see if it's going to blow or not.

What is the best way to charge it now? Balance or regular charge?

Could you have taken the side off the 1800 FS battery case to hold the LED checker thingy and put it on under the shrink on the new batt? Might have made it look more finished... Great mod guys!!

How Do you charge the unit as Fatshark ask to charge 18650 Batteries individually outside the case not the two together as in the fatshark case?

Love the RaseKraft Hat!

I think you should know, you can get 18650s with solder tags already welded onto the ends, so you don't have to risk them blowing up from trying to solder directly on to them.

i just purchased a fatshark battery, and it came missing the center wire on the balance lead... i opened it up and added it back in but the quality control out of the factory seems pretty bad... will be making my own from n.... i mean i'll have to find a better alternative to them.

@Rotor Riot, Try putting your volt meter on the red and white wire to read the other cells voltage.

the clip at the beginning is how I feel whenever I try to tune or configure.

do you use protected or unprotected batteries?

Great video keep up the great work

There are some cruel, sick people in this world.

Also 18650 cells can be bought with tags at approx the same price, so you don't need to worry about soldering directly to the cells.

If you want to measure the voltages of each cell through the balance connector, you start at the end with the black wire and put your negative multi-meter lead on that connector, and the positive multi-meter lead on the next connector to the right, measure the first cell, then move BOTH multi-meter leads ONE connector to the right to measure the next cell, and so on. So move the positive lead one connector to the right and then move the negative multi-meter to where you last had the positive lead. I know, it sounds counter-intuitive to put the negative where you just had the positive, but you are not reversing voltages, you are ISOLATING each cell. So as long as the battery's main leads are disconnected, no short will occur. That's how the balanced plug voltage meter works, not by subtracting.

Can this be on with the new fatshark 1800mah battery, the one without the balance lead.

How do you charge it ? From just the balance plug?
