Thank you for highlighting this product, learning about the hobby and one of the biggest questions I had was how to discharge and storage charge 1s batteries properly. Thank you very much!
I've made three of those 6x1S cables. Lots of testing with the DMM to assure myself that I had it correct. I like this board, one can charge less than six at a time. (edit) And it's cheaper to buy this compared to buying all the bits to make the cable.
Good point I forgot to mention... this is definitely way cheaper than the old way by buying all the wires and adapter pieces to make one yourself. With this now in existence, you'll only want to make a DIY one if you just like to waste time and money.
Good idea from my "DIY-Expert-Level" (ironi) I´d think of a click-based mounting of the power- and balancer cables on the PCB. This way the tiny cable strands are allways wiggling around a bit an will sheer of after a while.
Thank you for sharing this. I have been using a crazy pony board because its a 1s to 6s charge, but this one looks really good and is 1s dedicated. Its now on my shoping list.
Hah, I was just thinking this morning about trying to find or make something like this! I would like to see a 6-pos switch instead of the jumpers though, just to make it a little more idiot-proof. I currently use the betaFPV 6-battery charger, but it can't do discharging for storage. Unfortunately like half my bt2 lipos are puffed and dead now because I never got around to using them and they sat for a month at full charge 😅
yep so my first revision used dip switches and it didn't hold up the current; 6pos switches are hard to find in 2A and when you do they are bulky and expensive; this much current is AC territory so the bright red extended jumper was just the next best solution to get them out at an affordable price
@@fractalengineering Ahh, that makes sense! On the opposite side of things being idiot-proof, would you consider selling just the unpopulated board? I've got enough spare connectors and wires to build one lol
When we encountered this problem with diy vapes back in the day, we went switching mosfets of the appropriate load. I know cost and time prohibitive, but who knows maybe down the line you could refine a deluxe version 😉.
By the way, love the product! Soo, I can fit gnb27 in the bt2.0 hole if I line the banana plugs right, but not fully through hole. Would that be enough contact for light storage charging?
@@MissingNumb lol yes mosfets and even logic gates to detect the number of cells automatically has been discussed, but in the end it would remain useless without the charger, so the next step that would make sense would be a full-featured charger imo I have not had a gnb27 connector in hands, it might be bigger than BT2.0; in any case the purpose of these free holes are to solder a lead to it; I wouldn't recommend simply sticking live wires to it
NIce.....I just have one of those boards that set the whether the battery in an HV or not and a light goes out when charging is done. But there is no way to storage charge. So I just don't bother. I fly them down to about 3.5 and that's it. I may look into this gadget even though I don't fly whoops too much anymore. The lipos don't seem to last too long either. I should dump most of them and re-up.
Oh crap I made a diy harness just yesterday with 4 connectors and a 4s balance plug. Is there something I could do to charge less than 4? Like putting a connector on an empty slot and linking it’s + and - ? Dunno if that made sense.
No, you just need to get this board. I think getting all the parts to duplicate this functionality you want will actually cost you MORE than the board at $13.
Hii I have made something similar for 2s batteries. I am using for 1 year and a half and work well. If you have different capacity batteries wil also work but much slower because the charger try to balance the cells.
Yah I have that parallel charging board. It's a pain in the butt really. Waste a lot of time matching up the voltages, sorting 1s batteries into similar voltage piles hehheh. I have giant bags of them (thank you BetaFPV). This one looks a lot better.
@@stinerivera2543 yes; the idea was to have standard JST-PH for most batteries, as well as a BT2.0 footprint for direct solder, to which you may as well solder any custom connector on a lead
The only problem with this is that all the cells have to be the same capacity, whereas with parallel you can do any capacities you want, as long as the voltages match up
That's true but this is also not real parallel charging. It's creating a serial pack from individual packs so you can take advantage of modern smart charger balancing features. Still better than anything else out there now for 1S packs.
Well that's funny! I basically made the exact same thing myself a couple weeks back. Only my jumper solution is slightly different and I printed my own BT2.0 connectors 😉
It probably will (depending on the side you have shorted). Got to look at the traces but I guess one side is connected to the positive sides of the batteries, while the other side is all shorted and connected to the main red wire. this way you get to choose which series connected battery is connected to the main red wire.
@@sendorm Well the manual advises against it...however for the bravest of you, if you still insist on trying then yes it will utterly destroy...nothing lol, each pin on the top row lead to the VCC side of each cell, so there is a voltage potential of zero between any of them ;) The bottom row is a little more complicated, depending on how many lipos are plugged it may do nothing or dead short 1S; up to you, but I don't recommend it
@@fractalengineering Yeah that's also what I thought. Might I suggest a six way rotary switch for the job? It will do the same thing without any risk of short. Great idea though. Never thought about this. I just charge all my batteries at once :)
@@AlbertKimTV yea it was, I was just checking my balance to see what card to use and POOF gone. Great review though. Hopefully they'll be back in stock somewhere soon
@@AlbertKimTV I'm so sorry. I understand. I've encountered the same thing but on different subjects. sometimes people just need to look in the mirror and put blame where it belongs. Have an amazing day. I hope you get to fight time that you deserve today.

Glad it was helpful!
Good way to charge 1s! I like when you post videos at this time because my lunch at work is the same time.
YES this thing is awesome. I have been using it for 2 months and had no issues.
I have been using the same thing I made when I first bought a 1S whoop. That jumper idea is genius though.

Great review, Albert! Thanks a lot! 😃
Stay safe there with your family! 🖖😊
I just got this and didnt understand the directions. I knew you would have something on it. Thanks!
😁
Love my three fractal boards!! My first has the BT2.0 connectors as well as PH2.0 from first batch. I use the ToolkitRC charger too. Love it.
Thanks for sharing!
This will be great. Nothing like using my drone to discharge 1s lipos. It's gets tedious. I'm getting this.
Good idea

What a great board for balancing 1S batteries. Thanks Albert
This board is so well made and definitely needes for 1s Lipos. Only if they had more stickers with it lol the art is gorgeous.
Great review. Very useful tool. Thanks Albert 🤓
Glad it was helpful!

Lol, I know it's not funny Albert but your explanation of why you don't make certain videos Is funny. Gr8 content & keep up the awesome work you do.
😁
Super produit 👍👍👍👍👍j adore 🥰
FINALLY!!! Thanks Albert!
I build a similar one my self and it works great
nice video keep on going =)
Thanks for the great reviews as always! I was wondering if this board could be used with ISDT 608AC charger?
Can be used with just about most modern chargers.
hi,the jumper is good idea. and i use one with switches series with 6s
Will this work with my htrc t400 duo charger I use to charge my rc trucks with? Another great video
I'm not sure what connector that one has. You'd need an adapter for XT60 if it has something else.
Sold out everywhere. And no uk stock :(

Correct me if I am incorrect. The board looks like you could solder on bt2.0 connectors to the board next to the ph2.0 connectors.
Yes, they actually sell a version with just the BT2.0 connectors but you can add your own of course.
How would this handle multiple emax 2s batteries? Each PH2 would be 2 cells. would the jumper go to the 4 s pin?
This is not meant for that kind of battery. You'll probably start a fire, don't try it.
The extra holes on the board are for bt2 connector :)
also u can install gnb27 connectors in that extra slot fits like a glove...
Oh crap I made a diy harness just yesterday with 4 connectors and a 4s balance plug. Is there something I could do to charge less than 4? Like putting a connector on an empty slot and linking it’s + and - ? Dunno if that made sense.
No, you just need to get this board. I think getting all the parts to duplicate this functionality you want will actually cost you MORE than the board at $13.
Nice, finally. Out of curiosity, if you set the jumper to 5s but you put 6 batteries in the first 5 connectors, instead of 6, do you have a fire?
6 instead of 6? You question doesn't make any sense... 🤷♂️
@@AlbertKimTV I just wondered what happens if, by mistake, one inserts 6 batteries with the jumper still in the position for 5 batteries.
Be sure to read the manual linked by that QR code. You’re charging serially not parallel.
Do you have a link for those adapter leads ?

@@AlbertKimTV thank you !

This one looks a lot better.
so can you use different mah amounts for them like have one 150mah and one 300mah and charge them both?
No, that won't work. The capacity should be the same.
This is good thx for the link got 1 hope U get a cut haha 💰 happy flyin ✌🏼
Isn't this the same as a flying sandal?
I was wondering the same thing. I have the Flying Sandal 1s board. What's the difference?
@@Jonsbasecamp 6s maybe?
What are the solder points for?
What solder points are you referring to?
@@AlbertKimTV the one beside the ph2.0 connectors. It looks like a bt2.0
@@stinerivera2543 Yes, that is what those are. See the other comment from the creator of the board.
@@AlbertKimTV oh okay sir. That means you can solder any connector you want like the gnb one and even xt30 for 1s toothpicks?
@@stinerivera2543 yes; the idea was to have standard JST-PH for most batteries, as well as a BT2.0 footprint for direct solder, to which you may as well solder any custom connector on a lead
Now they just have to add 3x2s and 2x3s to that board 😁
Already sold out @NBD :)
The only problem with this is that all the cells have to be the same capacity, whereas with parallel you can do any capacities you want, as long as the voltages match up
That's true but this is also not real parallel charging. It's creating a serial pack from individual packs so you can take advantage of modern smart charger balancing features. Still better than anything else out there now for 1S packs.
@@AlbertKimTV if using the balance charging mode, do the cells have to be the same capacity?
👍👍
Well that's funny! I basically made the exact same thing myself a couple weeks back. Only my jumper solution is slightly different and I printed my own BT2.0 connectors 😉
does it short one battery if you put the Jumper in horizontally?
Not sure... I don't plan on testing that just in case it does...
It probably will (depending on the side you have shorted).
