Why your Whoop batteries die in storage and how to stop it

[@JoshuaBardwell]

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

[@vicenteriquelmezavala2110]

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

[@MrShutterBug]

I have 5 of the Tiny Whoop storage dischargers and they’re great! Pop them on and don’t worry about it. I wish I had more of them.

[@ratchet_hoe]

I use the fractal engineering series board. You can use a jumper pin to select 1s-6s so that you can plug in however many batteries you want.

[@theflyingsandalrc]

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! kzbin.info/www/bejne/g6CvkmCgmJiLrdU

[@kurtzFPV]

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.

[@tonhabraken9339]

Wanted to say the same. The Fractal Engineering one is awesome.

[@JoryFPV]

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.

[@btbplanevids]

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.

[@nosmokingnl]

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.

[@monajafi5020]

Every time I’ve faced with a problem you come with a solution. You are awesome.

[@jonaswalther9245]

I have built and used this type of serial adapter for over 6 years as I have flown many 1S helicopters over the years.

[@malelonewolf80]

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.

[@screamatthewind]

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.

[@xDownSetx]

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.

[@davelowets]

You can simply soak them in saltwater and dispose of them

[@DerDirkBelana]

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!

[@p.1206]

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.

[@eedok]

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

[@ProDangles]

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!

[@licensetodrive9930]

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.

[@scottchaffee1004]

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

[@Suraj_Mandal.]

[@TomicaCZ]

I will GLADLY repeat myself.... Thank you for all of us JB. You are doing awesome job gor the community!

[@FabioKastro]

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

[@661FPV]

Yup I make my own series 1s cables with ph2.0 cables, a 5s balance lead, and an xt60. Priceless. I have a 5s and a 4s one also. Store at 1C.

[@zachmachina]

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.

[@bigb69ti]

you should get in talks with one of these companies, and have them make a 1s charger that puts them into storage. you would think by now they would have came out with this. they just need some one like you to help push it

[@kool-k-kel]

Cheers JB, especially love the bit about the storage pair to charge the 2. Good to know!

[@ErraziBProductionS]

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.

[@tq64to4]

[@dimitarkrastev6085]

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.

[@yonseimatt]

Hah! I posted my comment before I read yours. Yes, this is what I do, series charge cells with different capacities, no problem.

[@mitch6131]

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!

[@off-grideverything533]

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.

[@gilebike]

[@vhfgamer]

[@vhfgamer]

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!

[@rasmus80g]

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...

[@chibikaiju922]

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.

[@michaelstidham2891]

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.

[@wam7484]

Reluctant to start an argument over time-honored concepts, so will just quote from the GNB (Gaoneng) package insert: "Our testing also revealed that storing the packs at 3.3 volts per cell (high voltage 3.4 vpc) is optimal for retaining the capacity as high as possible." FWIW Gaoneng says they are one of the largest manufacturer of lipo batteries in the world. Do what you will with the info. I've seen similar numbers several times now from manufacturers.

[@VIFLYDrone]

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

[@pgabrieli]

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

Finally. Serial has been the only way to charge 1s forever, but we always had to make our own adapters.

I wouldn't combine them into one battery if they're that different though. Usually cells are charged in serial, and discharged individually, so if one is fully charged, it will take forever.

Great info as always B. I've killed more whoop lipos than any other.

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 👍.

[@everythingquads]

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.

[@meroonghazwan2793]

Hi Josh, Regarding reduced battery life that we usually notice much more often with 1s cells, well i would guess primarily the reason is that they're built with lower quality materials overall.... But trust me and I'm speaking from experience of more than 6 years in lipo & lion cells, the number one reason which is controllable that reduces battery life is charging end voltage and discharging end voltage, and the well known Temperature So if you want to increase the cycles of any battery you've to compensate with those factors, i would highly recommend that you test charging a normal lipo to 4.10 end voltage and see for yourself the impact on battery life And remember lihv cells generally don't last as long as normal lipos, reason being that they're primarily normal lipos with slightly modified chemistry to give broader range of use, but what you pay in return is reduced battery life due to more strain on the battery itself ( charging to full 4.20 or 4.35 incase of lihv) really push these batteries to their limits! That's what I want to highlight BTW you're doing great for the community and i love you videos, keep it up

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.

[@MichaelDFPV]

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😉

[@KingFPV]

I like it & probably will get this to compliment my Ultra Power UP-S6AC 1S charger

[@machafpv4049]

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.

[@michaelwilkes0]

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.

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

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?

[@JoshuaBardwell]

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've always storage charged to 3.85v -is 3.8v a better voltage to store at?
