An alternative method is this 1S storage-charger from Tiny Whoop. It plugs into the battery and discharges it slowly to storage. The main difference is that it goes slower than most chargers, and it only does one pack at a time. For a cost of $5 each, you will probably spend less money and go faster with a series board. But the Tiny Whoop method is much simpler--just plug and forget. www.tinywhoop.com/products/tiny-whoop-1s-discharger-pw-jst2-0-battery
the tiny whoop discharger works fine for me, but they only work to reduce(discharge) the voltage on batteies. so if they are low already you 'll need to charge some juice first
Hi, I have just released V2 of these boards. I have done my best to address the feedback while maintaining the originality, ease of use and simplicity of the original, I hope you enjoy! ua-cam.com/video/MoLa-jc3Xws/v-deo.html
Fractal engineering makes an inexpensive switchable one that works very well too for 1 up to 6 batteries. I've had mine for over a year and it is still going strong. You do have to remember to move the jumper pin bridge to the appropriate number you are charging though.
Just build or buy 1s to 6s cable. I posted a link but its probably got filtered. iti is about 10 per cable and you can use it in paralel and charge/discharge/store 6/12/18/24/30 batteries in one go.
Handy product for people who don't have the skills/confidence to DIY something similar from a 6S JST-XH (balance plug) connector and six 1S pigtails. I made those for each of the three micro connector types I have on 1S packs (I don't just fly Whoops), and always putting them at storage voltage after flying has *definitely* improved their lifespan.
As someone who primarily flies whoops these boards are indispensable. I prefer the Fractal Engineering version, but even a handmade cable is fine. It's so nice being able to throw 12 batteries on my HOTA D6 and storage charge without having to check voltages first. Sometimes I fly 1s just because it's so easy and convenient to work with the batteries.
Finally, a video sharing my concerns and not saying, why worry about a 5 dollar battery. There are great 4 port chargers for these 1s lipo's. They only miss a storage option. These kind of boards are great, but having 4 independent ports does sound like a more ideal solution. Connect, press storage, Wait.
I understand the use somewhat but why not fly the battery down to 3.7 or 3.6 then just charge it back up to 3.8? I normally fly 10 packs down to 3.6 then use a charger with an indicator from BetaFPV to charge two at a time to 3.8 while I contemplate the void of nothingness.
VIFLY 1S battery storage charger is on the way, 2 options, charge full or strorage charge, if you choose storage charge, it can charge it to storage voltage if it is below it, it can dischage it to storage voltage if it is above it.
I just soldered a bunch of xt60 to PH2.0 and stick them on my parallel board and discharge them like normal. The charger gets confused because there’s no balance lead but it’s 1s so it doesn’t matter. Works like a charm.
Thank you so much for this video! I've had one of these for months, and have been wasting so much time trying to get batteries within similar voltages before using it, as if it were parallel. I knew it was in series, but didn't know I could have different voltages! Thanks again!
You are right, for all of us who know how a lipo is made up it is a no brainer to do this at home with cables, connectors and a soldering iron. We all have this flying around. But for all people who are starting or do not go into electronics and wiring at all, it is not that obvious. Great job Joshua. AGAIN!
It's funny how fast FPV goes, I haven't used the flying sandal board since the webleed fractal board came out, it's pretty similar, just has 2 more ports and can do both PH2.0 and BT2.0, goes great with the new webleed BT2.0 batteries
After watching your video, I grabbed all my tiny whoop batteries from my pack downstairs and have them charging. They needed a charge but also benefit from being on the warm steam radiator in the kitchen. The cold seems to sap their energy quickly. I look forward to watching your whoop racing video you posted. FLY HIGH Joshua
It is way more easy to just charge up every battery to full charge, then use the batteries for half their usual flight time before putting the batteries away for storage. The batteries will in most such cases be between 25% - 80 % and thus not take too much damage from storing. One could probably DIY some contraption were one could monitor the voltage of the battery while using battery with a motor/esc solution to get the battery at the voltage level one prefers / more exact voltage level. This can also be done on multi-cell lipos (2S and more), but that leaves the batteries unbalanced during storage. Not the biggest of problems, if one has made sure that one cell will not self-discharge to an unsafe level during storage. But for 1S batteries there is no balancing (unless you use multiple 1S batteries as cells in a multi-cell battery). So with 1S batteries I find it simpler to just use them for half their ordinary flight time, which puts them within a safe voltage level for storage.
i just made myself 1S series board by designing in EasyEDA 7-8 months ago and works perfectly, and now it's very easy to manage them, barely cost me $2
I stopped flying for about 3 years and left all of my 4S 1300mah Tattus at full charge. They all sag out simply by hovering now. Time to rebuild the battery hoard, and discharge the batteries immediately if not in use! An expensive oof.
This is genius and a critical tool to have, thank you so much for this video. I just ordered two of the one's from Amazon with the switches, those look like a great idea for my needs. Thanks for another banger Joshua!
I've just started using the cable adapter that connects the battery in series awesome little cable and now I know how I can make my own for however many batteries I have. Strange why no chargers have storage functionality
I made my own version of that board, but I put 6 PH2.0 sockets on it in a 3S2P configuration, so it can deal with 3 or 6 batteries simultaneously. I also made a cable to plug a single whoop battery into the charger, using an XT60 plug, 2S balance plug (with the 3rd wire removed), and a PH2.0 socket.
Yeah, one thing I've worried about. One, 1s pack I use daily, so don't bother with it too much. But my other ones, I either put on a charger, with readout so I can pull them just past 3.8, or if I don't get to fly them, I have a uruav lipo killer, that will bring them down to storage.
Tinywhoop dischargers are the best. Get a keychain full of them and then any overcharged batteries you just plug in and it takes them to storage. Gotta charge up the discharged batteries a little but that's a much smaller deal than discharging imo.
Hi, Joshua. I moved my mobula6 to 75mm - but unlike on all videos on internet, it just doesn't fly well. Vibrations makes it unflyable. Problem only happens when I put 4 blade 40mm props on it, with native 31m 3 blade props even on 75mm frame it flies OK. I think it would be very helpful for the beginners if you could explain what are these filters, p I d thiks mean, but in simple terms and how to set it up. I found video how to use blackbox gyro data, but unfortunately there's no blackbox on tinywhoops =( Thanks!
Thanks for this video. I have already been through a dozen 1s batteries over the past few months. I picked up the Fractal Engineering board with both types of connections and it is working great. Highly recommended!
I have asked for 1s chargers to have a discharge option for years and I don’t know why nobody has done it. I have been using the Tiny Whoop ones but got one stuck on and couldn’t get it off without mangling the plug and yeah, they are slow. I wasn’t aware of the one you used, so going to have to pick one up!
Thanks for this video! It's going to help save a lot of peoples 1s batteries this whoop season. I love the ability to parallel charge (or series in this case) but I hate having to micromanage pack voltages so I just made a bunch of bt2.0 to xt60 connectors and charge/storage charge my whoop batteries individually directly off my d6 pro like i do my 6s packs. Its slow but gets the job done and keeps my 1s packs healthy.
Have been running the same 1s batteries really hard for 6 months with no issues, at least 100 outdoor flights on each using various aircraft. They get store/charged every day. All the Crazypony 650's died quickly, they never lived up to their specs anyway, tossed them. Having success with Tattu, EMAX, and GNB. Wish I would have seen this video earlier, could have saved a couple bucks. Just bought my 3rd & 4th ViFly Chargers from RDQ. The first ones off the line had some issues, thinking about retiring that one even though it still works reasonably well. The newer ones work like a charm.
One of the first things I did when I got a decent charger, after having only had a small 1S whoop for a long time, was to create an XT60 to PH2.0 adapter. This was so I could charge my 1S whoop batteries just like any other LiPo 2S-6S pack without any sort of parallel board involvement.
I converted my tinyhawk II and 1s batteries to xt30, has worked pretty well so far. I’ll definitely keep my eyes pealed so I don’t kill them all during a parallel charge though.
That shows the one complaint I have with my charger, the storage setting is unfortunately not a balance setting. Suggestions on what to look for when purchasing a charger to verify if does that?
I fly so much whoop that I simply go through batteries and this doesn't affect me as much as most pilots. I'm like buying batteries often. But, I really need to up my charge game. Great video ,thank you.
Hi Josh finally a 1s balance board. I been using aph2 connector to a xt30 adapter to storage charge this is so much better. Thanks for the video and information
I have a pile of those little gadgets Tiny Whoop sells that puts the batteries at storage. Gee I got those a WHILE ago, I'm not even sure how long. But they work great!
Thanks for the tips that was great , on a side note, I think you can run that with less then 4 batteries, but tell the charger as if 2s 3s . . Cheers and thanks a lot
I have the URUAV Lipo Killer...I got I for killing XT60 batteries but....it has a balance plug that discharge balances also...AND it can discharge my 1s to storage. Only bad thing is it’s one at a time but tiny whoop batts don’t take long each.
I don't think charging batteries with different capacity in series makes any difference. What you say is completely true when building a multi-cell battery. You need to match the sizes, because when you fly a battery you use the sum of all voltage across the cells. A higher capacity cell may sit at 4.0V because it is not drained yet, while another cell could already fall at 3.0V giving you a total of 7V (3.5V average per cell) but you can see the problem with that. The smaller cell will probably die after a few such flights because you don't "balance discharge them". In charging though you can mix different capacities as long as you use the balance charge function. The charger will equalize the cells. If you charge without balance (which doesn't make sense since it is the whole point of this border it seems) it will just take longer to "balance" the higher capacity cells and I don't feel like the charger will mind that and it would be all the same for the cells I think.
isn't this device exactly the same as these typical cable adapters that look like an octopus? They convert 4x1S little batteries into a 4S one so that one can use them on typical big multi-chargers like yours.
I’ve been doing something similar for years diy, but why hasn’t a company come out with a stand alone charger yet? If I remember right once upon a time bardwell was even talking about getting one made but abandoned it?
@@JoshuaBardwell I get that, I’m working on my own that would do charge, capacity test and storage. Nothing worse then falling out of the sky 5 feet from the starting gate because the battery is shot and you don’t know it.
IDK if anyone will see this, but I wanted to say I think this videos is awesome! Thank you so much for making and posting it. I have one request, could you please comment on this process for small 2S batteries? I'm talking about 180-200mAh, 7.6V 50C 2S batteries. The use is for 150g robots but I have to purchase ones designed for tiny cinewhoops (I apologize for the noob question). Is there a product for placing them at storage voltage? Do you already have a video on it? Thank you very much for your help.
My question is why do these nbd lipos seem to puff while in storage voltage . I’ve had a lot of them just puff randomly while at storage voltage, granted they weren’t new and I felt I got my money’s worth out of them before they puffed randomly
When I got into whoops, I build a series board on a breadboard. It has a switch so I can charge in a 1, 2, 4, or 6s configuration. Capacity does not matter if charging single cells in a series configuration. The cells with be charged or discharged to the set voltage irrespective of capacity.
Maaan, when I know I will be storing next...on my last flights I just use up to about 3.8v left and that's it...for all of my 4 batteries. Then check just to make sure but at this point I know the 3.8 mark.
Series Charging, that's what i used to do a few years ago. Plug them in, they are recognized as a big 6s or whatever pack and then select Storage Charge or Balance Charge, depending on what you want to do. I used to DIY my own series cables
Well I think you missed one point. The balance port is only discharging and the main port is charging. That means if you do plug in batteries with different voltages it will need to discharge the ones with high voltage to be able to charge the ones with low voltage to set voltage. Basically the high voltage cell will need to go thru an extra cycle. So I would still suggest using approximately same voltage on all cells if possible. It will go faster and will create less wear on the batteries. It is definitely not as important as in parallel because nothing vill short or break. but if you can sort them out avoid to much difference that is a good thing and should be recommended. Also most chargers won't do storage on 1s so a series connection is a must on most chargers. I just soldered a 2s conversion to be able to do this on mine. If I where to create a 4s series board I would put in a switch to be able to change it between 2/3 and 4s on main port...
i use the banggood cable, it's basically the same experience, pretty useful. but i do wish i could find a parallel board for 1s, because there's only a 4s and 6s version, and i wish i could just leave one out. e.g. when i broke in 3 new batteries, i had to run extra cycles on one of my older ones just to have a 4-pack. plus i have 5 moblite batteries, and i can only charge/discharge 4 at a time. the fractal engineering board looks like a good solution, too bad it's US only.
The Fractal Engineering board has a jumper to set it from 1s - 6s. Just set the jumper to the number of lipo's connected to the board. 😉 Not US only. You can pick one up from Drone FPV Racer. If you are in Europe😉
Isn’t the last part incorrect? If you set your charger to 4s it can’t and should not load 2s? 🤔 other series boards have a switch to select the count of cells on it. Maybe that’s why?
Joshua I have a question I hope maybe you can give me lead with as I have no one to guide me over. I have built a tiny whoop weight 23.8 g. with 802 motors 22000 KV. The FC is Betafpv 5A ELRS AIO. I applied their diff. All parts are top notch. On Angle mode when armed and drifts backward and increase motors spin until flipping over. In rate mode I can tame it but it's still hard to control. Do you have any suggestion or some direction I can advance with?
@@theflyingsandalrc Thanks for reaching out. I had the product for a while, I'll likely just replace the plug connectors with BT2.0 connector and I'll be fine.
Just a heads up, you can charge lower counts of cells with the board, you just need to make a jumper to link (in the example of 2s in a 4s board) cell 1 negative to cell 2 positive, it will fix the issue and jumper past the 2 empty positions. The XT60 is connected to only the negative of cell 1 and the positive of cell 4 in this model, so when you only connect 2 cells you have a gap between the xt60 negative and cell 3 negative and as we know the charger is trying to charge through the XT60 and balance using the balance connection.
On the RDQ description it says that it will expect the board to I’ve a diff. Of only 0.3 V per cell as it’ll expect it to behave as a battery back, does this not matter due to the HOTA being smart enough to compensate? That’s why you had a diff. Of 0.5 v?
Funnily enough, I recently took some surplus connectors and made a 3S series harness to do the same thing. I have been using same capacity cells each time just in case - thanks for confirming that I absolutely must do that; I wasn't sure. After flying, I used to put them on one of those parallel boards that shows the voltage and pull them off when they showed 3.85-3.90V (I think HV batts are supposed to be stored a bit higher voltage?) but having to look at the board every few mins was a right royal PITA!
Can you used these to kill your puffy packs? I’ve got some plug dischargers for my xt60 packs but nothing for ph2.0 little packs. Those storage drainers from tiny woop would be great if they had a zero option!
when you tried just 2 batteries, try changing the charger from 4s to 2s before hitting the go button and see if its happy. the isdt8 seems to be happy doing 2s even though a 4s balance wire is plugged in.
haha josh went ego super saiyan at the end ROFL, ive been putting my 1s batteries into storage charge when not in use since i started the hobby lol in fact, the thought of my packs not in storage charge would make me panic but my solution was to take the ph2.0 pigtails i had laying around and make xt60 to ph2.0 adapters for those that want to go direct to their chargers and for a cheaper price to achieve the same goal.. however i do envy not having a 4s series ph2.0 board
Great info as always B. I've killed more whoop lipos than any other. My issue right now Iis that ive been on a 18 month hiatus from fpv due to work and life and just started checking my old 4s and 6s lipos lol(yes I know need all new lipos now, I accept cash donations for anyone who wants to send my way 😋) All put into storage charge July 2020 and so far 10 out of 15 6s and 4 of 8 4s and the solo 5s pack I have are still at storage voltage. Still checking the last few packs now. All my 4s packs but 2 already needed to be tossed into file 13 but the 3 new ones holding storage well after 18 months, I wouldn't expect less from rebel lipos 👍. Now hopefully after the holidays I can get back to fpv, I miss flying so damn much. 😢 already have the workbench full of parts waiting to get soldered together.
Sorry to report the storage voltage Amazon link sent me the charge/discharge board but it keeps failing to operate. Using the same system you have in this video: hobbymate + HobbyFly. Fails every time ….any suggestions ?
You can also solder BT2.0 connectors on the Fractal board. That is what the spaces next to the PH2.0 connectors are for. Factal made a batch of the boards back in September. Looks like their site no longer has any and are currently only available one of their resellers. I am not mentioning the site in this comment, since maybe that is why my post keeps getting deleted. Check out Fractal Engineering's FB page and look at their post from September 28. 😉
Good video. The problem with 1s batteries apart from the life span is not all the connectors are the same. I dont think mine with the JST connections would fit on this board. I have spent more on 1s batteries than I have on tiny whoops and I dont think any of the batteries work anymore so I have given up on ever flying tiny whoops again. Its not worth the investment unless you are doing it all the time.
another vote for the fractal engineering board, much more versatile than this. first of all because you can use up to 6 batteries at once instead of just 4, and perhaps more importantly because you have a jumper to set how many you want to use, so you don't have to plug in 4 regardless as here. excellent if you have only 2 or 3 "odd" ones with different mah ratings (e.g. I only have a couple of 850mah 1S). the flying sandal is good, but the fractal engineering board is vastly superior, in my opinion
I just plug mine back into my 6x 1s charger. Charge till about 3.9 and take em off. They rest at 3.85 for storage. Takes 10 min. Just set a timer to NOT forget.
I do the exactly same with my betafpv bt 2.0 bateries after flying just charge them for 10min on 6x charger and all have 3,80-3,85v. This is simple and so easy :) But i noticed performance drop about 20-25% flight time less after 100 cycles of charging.

Mr Jessie Perkins sales in Tiny Whoop small device like a storage 1s discharger,coast a few bucks and it works really fine,and it is accurate.
Yeah that, I have a pile of those. They're good.
Have been running the same 1s batteries really hard for 6 months with no issues, at least 100 outdoor flights on each using various aircraft. They get store/charged every day. All the Crazypony 650's died quickly, they never lived up to their specs anyway, tossed them. Having success with Tattu, EMAX, and GNB. Wish I would have seen this video earlier, could have saved a couple bucks. Just bought my 3rd & 4th ViFly Chargers from RDQ. The first ones off the line had some issues, thinking about retiring that one even though it still works reasonably well. The newer ones work like a charm.
Thank you for this video! I made some adaptors from XT60 to BT2.0. But this is much more efficient 😃
One of the first things I did when I got a decent charger, after having only had a small 1S whoop for a long time, was to create an XT60 to PH2.0 adapter.
This was so I could charge my 1S whoop batteries just like any other LiPo 2S-6S pack without any sort of parallel board involvement.
Been duying for a video like this 🙏🏻 Thx Joshua 🙏🏻
I converted my tinyhawk II and 1s batteries to xt30, has worked pretty well so far. I’ll definitely keep my eyes pealed so I don’t kill them all during a parallel charge though.
That shows the one complaint I have with my charger, the storage setting is unfortunately not a balance setting. Suggestions on what to look for when purchasing a charger to verify if does that?
The storage setting should bring all cells to 3.8 volts, effectively balancing them. At least that's how all the chargers I've used do it.
@@JoshuaBardwell my charger doesn't balance when doing the storage settings.
I fly so much whoop that I simply go through batteries and this doesn't affect me as much as most pilots.
I'm like buying batteries often.
But, I really need to up my charge game. Great video ,thank you.
Hi Josh finally a 1s balance board. I been using aph2 connector to a xt30 adapter to storage charge this is so much better. Thanks for the video and information
I bought wire harnesses to parallel charge them and use those. Haven't had much of an issue. Having the board probably helps manage it better
I have a pile of those little gadgets Tiny Whoop sells that puts the batteries at storage. Gee I got those a WHILE ago, I'm not even sure how long. But they work great!
Thanks for the tips that was great , on a side note, I think you can run that with less then 4 batteries, but tell the charger as if 2s 3s . . Cheers and thanks a lot
is this the same as a fratal board ?
I have the URUAV Lipo Killer...I got I for killing XT60 batteries but....it has a balance plug that discharge balances also...AND it can discharge my 1s to storage. Only bad thing is it’s one at a time but tiny whoop batts don’t take long each.
The URUAV with an XT60 for killing and balancer for discharging doesn't work with LiHv 4.35 Volt batteries...
I have two units with the same problem..
I don't think charging batteries with different capacity in series makes any difference.
What you say is completely true when building a multi-cell battery. You need to match the sizes, because when you fly a battery you use the sum of all voltage across the cells. A higher capacity cell may sit at 4.0V because it is not drained yet, while another cell could already fall at 3.0V giving you a total of 7V (3.5V average per cell) but you can see the problem with that. The smaller cell will probably die after a few such flights because you don't "balance discharge them".
In charging though you can mix different capacities as long as you use the balance charge function. The charger will equalize the cells.
If you charge without balance (which doesn't make sense since it is the whole point of this border it seems) it will just take longer to "balance" the higher capacity cells and I don't feel like the charger will mind that and it would be all the same for the cells I think.
Hah! I posted my comment before I read yours. Yes, this is what I do, series charge cells with different capacities, no problem.
Fractal’s board has 6 ports and it’s been around for a long while. Love both of my Fractals.
Yep,, great board that is very well made.
havent tried this before, so you plug that in as a 6s like in bardwells video?
@@manbolomo yep!
isn't this device exactly the same as these typical cable adapters that look like an octopus? They convert 4x1S little batteries into a 4S one so that one can use them on typical big multi-chargers like yours.
As far as I know isnt ot also okay to charge different mAh 1s lipos in series as long as you select the "lowest mAh" for charging?
I’ve been doing something similar for years diy, but why hasn’t a company come out with a stand alone charger yet? If I remember right once upon a time bardwell was even talking about getting one made but abandoned it?
Yep I was trying to get a 1S charger with storage function made but so far, nothing has come of it. I guess it's harder than it seems :-/
@@JoshuaBardwell I get that, I’m working on my own that would do charge, capacity test and storage. Nothing worse then falling out of the sky 5 feet from the starting gate because the battery is shot and you don’t know it.
IDK if anyone will see this, but I wanted to say I think this videos is awesome! Thank you so much for making and posting it.
I have one request, could you please comment on this process for small 2S batteries? I'm talking about 180-200mAh, 7.6V 50C 2S batteries. The use is for 150g robots but I have to purchase ones designed for tiny cinewhoops (I apologize for the noob question).
Is there a product for placing them at storage voltage? Do you already have a video on it?
Thank you very much for your help.
Make an adapter and use your regular charger for maintaining those. JB also has a video on how to make a harness for quickly charge balancing them
@@theflyingsandalrc Thank you
How is the Lawsuit with the faa and going?
you can do less than 4 cell but the rest has to be jumperd (short circuited)
My question is why do these nbd lipos seem to puff while in storage voltage . I’ve had a lot of them just puff randomly while at storage voltage, granted they weren’t new and I felt I got my money’s worth out of them before they puffed randomly
When I got into whoops, I build a series board on a breadboard. It has a switch so I can charge in a 1, 2, 4, or 6s configuration. Capacity does not matter if charging single cells in a series configuration. The cells with be charged or discharged to the set voltage irrespective of capacity.
Great video. I'm waiting for my 1s series boards to arrive. Not sure why I have never gotten around to purchasing them sooner 🙄
Maaan, when I know I will be storing next...on my last flights I just use up to about 3.8v left and that's it...for all of my 4 batteries. Then check just to make sure but at this point I know the 3.8 mark.
Series Charging, that's what i used to do a few years ago. Plug them in, they are recognized as a big 6s or whatever pack and then select Storage Charge or Balance Charge, depending on what you want to do. I used to DIY my own series cables
Well I think you missed one point. The balance port is only discharging and the main port is charging. That means if you do plug in batteries with different voltages it will need to discharge the ones with high voltage to be able to charge the ones with low voltage to set voltage. Basically the high voltage cell will need to go thru an extra cycle. So I would still suggest using approximately same voltage on all cells if possible. It will go faster and will create less wear on the batteries. It is definitely not as important as in parallel because nothing vill short or break. but if you can sort them out avoid to much difference that is a good thing and should be recommended. Also most chargers won't do storage on 1s so a series connection is a must on most chargers. I just soldered a 2s conversion to be able to do this on mine.
If I where to create a 4s series board I would put in a switch to be able to change it between 2/3 and 4s on main port...
Can u explain how those chargers balance the batteries...
ua-cam.com/video/XEIWdZHXK1c/v-deo.html
Good Video, thanks! Why Do you Prefer a Board over those cables e.g the one from BG? Is there a difference?
Great video! I have the Fractal Engineering board that NBD sells - same deal, just has 6 ports instead of 4. :)
And it lets you change how many batteries you want to put on
@@tdogfpv True, a jumper lets you set from 1-6 which is nice. Great board!
Fractal Engineering board is the way to go for sure... if you can find one
@@IveGotWood1000 NBD has them in stock right now :)
03:07 They don't need to be the same mAh either. The smallest one defines max current for dis/charging. That's it.
i use the banggood cable, it's basically the same experience, pretty useful. but i do wish i could find a parallel board for 1s, because there's only a 4s and 6s version, and i wish i could just leave one out. e.g. when i broke in 3 new batteries, i had to run extra cycles on one of my older ones just to have a 4-pack. plus i have 5 moblite batteries, and i can only charge/discharge 4 at a time.
the fractal engineering board looks like a good solution, too bad it's US only.
The Fractal Engineering board has a jumper to set it from 1s - 6s. Just set the jumper to the number of lipo's connected to the board. 😉
Not US only. You can pick one up from Drone FPV Racer. If you are in Europe😉
Isn’t the last part incorrect?
If you set your charger to 4s it can’t and should not load 2s? 🤔 other series boards have a switch to select the count of cells on it. Maybe that’s why?
If you plugged in only two cells in socket one and two that should then Reed is a IIs battery
The XT60 still won't have any voltage on it until the board is fully populated.
@@JoshuaBardwell weird. Thought it would work just like hooking up a 4S vs 6S
I just built a custom cable for serial charging and use that. Could not find anything ready to use online.
Joshua I have a question I hope maybe you can give me lead with as I have no one to guide me over. I have built a tiny whoop weight 23.8 g. with 802 motors 22000 KV. The FC is
Betafpv 5A ELRS AIO. I applied their diff. All parts are top notch. On Angle mode when armed and drifts backward and increase motors spin until flipping over. In rate mode I can tame it but it's still hard to control. Do you have any suggestion or some direction I can advance with?
Sounds like your board needs to be calibrated for level, 1st tab on Beta flight configurator. To get JB, just catch him on his live stream
@@theflyingsandalrc It was a bad Gyro.
Tiny whoop mini dischargers are great also, that Flying Sandal requires 4 batteries to work. worked great till one of the connections fell off.
Hi there, sorry you had an issue with your board. Send me your contact info and I'll shoot you a replacement. Thanks for using the board!
@@theflyingsandalrc Thanks for reaching out. I had the product for a while, I'll likely just replace the plug connectors with BT2.0 connector and I'll be fine.
So the one from Amazon would be the better option so you can charge any amount from 1-6 batts? Is my assumption correct @Joshua Bardwell
Just a heads up, you can charge lower counts of cells with the board, you just need to make a jumper to link (in the example of 2s in a 4s board) cell 1 negative to cell 2 positive, it will fix the issue and jumper past the 2 empty positions. The XT60 is connected to only the negative of cell 1 and the positive of cell 4 in this model, so when you only connect 2 cells you have a gap between the xt60 negative and cell 3 negative and as we know the charger is trying to charge through the XT60 and balance using the balance connection.
I had this same question several years ago to one of my RC friends. How do you put those small batteries into storage, he shrugged his shoulders.
On the RDQ description it says that it will expect the board to I’ve a diff. Of only 0.3 V per cell as it’ll expect it to behave as a battery back, does this not matter due to the HOTA being smart enough to compensate? That’s why you had a diff. Of 0.5 v?
Funnily enough, I recently took some surplus connectors and made a 3S series harness to do the same thing. I have been using same capacity cells each time just in case - thanks for confirming that I absolutely must do that; I wasn't sure. After flying, I used to put them on one of those parallel boards that shows the voltage and pull them off when they showed 3.85-3.90V (I think HV batts are supposed to be stored a bit higher voltage?) but having to look at the board every few mins was a right royal PITA!
Can you used these to kill your puffy packs?
I’ve got some plug dischargers for my xt60 packs but nothing for ph2.0 little packs.
Those storage drainers from tiny woop would be great if they had a zero option!
That's nice for that type of connector but what about the BT2.0 plugs like on the BetaFPV 1S batteries?
I use a TinyWhoop discharger with a BETAFPV adapter lead BT2.0 to PH2.0
when you tried just 2 batteries, try changing the charger from 4s to 2s before hitting the go button and see if its happy. the isdt8 seems to be happy doing 2s even though a 4s balance wire is plugged in.
You could put wire links in unused battery sockets, so if you have just 4 batteries connected, link out 2 sockets and select 4s in the charger.
Thanks man. Fpv newbie and this will save my wallet from becoming as thin as my batteries lol
I made myself a diy 5s board from protoboard and connectors
MuteFPV made a nice video about a DIY 1s serial board where you can charge 1 to 6 batteries
haha josh went ego super saiyan at the end ROFL, ive been putting my 1s batteries into storage charge when not in use since i started the hobby lol in fact, the thought of my packs not in storage charge would make me panic but my solution was to take the ph2.0 pigtails i had laying around and make xt60 to ph2.0 adapters for those that want to go direct to their chargers and for a cheaper price to achieve the same goal.. however i do envy not having a 4s series ph2.0 board
will you add the board to your website? or mention it?
Great info as always B. I've killed more whoop lipos than any other. My issue right now Iis that ive been on a 18 month hiatus from fpv due to work and life and just started checking my old 4s and 6s lipos lol(yes I know need all new lipos now, I accept cash donations for anyone who wants to send my way 😋) All put into storage charge July 2020 and so far 10 out of 15 6s and 4 of 8 4s and the solo 5s pack I have are still at storage voltage. Still checking the last few packs now. All my 4s packs but 2 already needed to be tossed into file 13 but the 3 new ones holding storage well after 18 months, I wouldn't expect less from rebel lipos 👍. Now hopefully after the holidays I can get back to fpv, I miss flying so damn much. 😢 already have the workbench full of parts waiting to get soldered together.
Sorry to report the storage voltage Amazon link sent me the charge/discharge board but it keeps failing to operate. Using the same system you have in this video: hobbymate + HobbyFly. Fails every time ….any suggestions ?
What about BT 2.0 batteries?
You need a ph to bt adapter.
You can also solder BT2.0 connectors on the Fractal board. That is what the spaces next to the PH2.0 connectors are for. Factal made a batch of the boards back in September. Looks like their site no longer has any and are currently only available one of their resellers. I am not mentioning the site in this comment, since maybe that is why my post keeps getting deleted. Check out Fractal Engineering's FB page and look at their post from September 28. 😉
That's convenient, is it possible to do the same for 2s batteries with 6s charger (charging 3 batteries as the same time)?
Yes if you had a cable wired the right way.
Good video. The problem with 1s batteries apart from the life span is not all the connectors are the same. I dont think mine with the JST connections would fit on this board. I have spent more on 1s batteries than I have on tiny whoops and I dont think any of the batteries work anymore so I have given up on ever flying tiny whoops again. Its not worth the investment unless you are doing it all the time.
why did you chose LiHv type for them? I am buying this for my 1s battiers too...Thanks a lot
All whoop batteries are HV. They're so small you basically have to over-charge them to get any reasonable flight time.
you forgot about Fractal Engineering and CleanBoard
another vote for the fractal engineering board, much more versatile than this. first of all because you can use up to 6 batteries at once instead of just 4, and perhaps more importantly because you have a jumper to set how many you want to use, so you don't have to plug in 4 regardless as here. excellent if you have only 2 or 3 "odd" ones with different mah ratings (e.g. I only have a couple of 850mah 1S). the flying sandal is good, but the fractal engineering board is vastly superior, in my opinion
I just plug mine back into my 6x 1s charger. Charge till about 3.9 and take em off. They rest at 3.85 for storage. Takes 10 min. Just set a timer to NOT forget.
I do the exactly same with my betafpv bt 2.0 bateries after flying just charge them for 10min on 6x charger and all have 3,80-3,85v. This is simple and so easy :) But i noticed performance drop about 20-25% flight time less after 100 cycles of charging.
I thought since there 4 of the .3 amp batteries, you would be able to charge at 1.2 amps?
If they were on a parallel board, yes, but they are in series, so the current needs to be based on the cell capacity.
@@ASJC27 ah, makes sense. Thanks for the response
