his device is nowhere near safe, all he's doing is running the 4 resistors in parallel and using the pin on the negative side to manually choose how many resistors to combine into the array from 1-4, he ideally should have 5 resistors to reach 30 amps or near it. like i said it's safer to solder them and not has a pin that could be making poor contact, this would never pass a UL rating
The little plug for balancing 2s has to be connected to the 1S positive lead to make it work. I like the idea of adding or subtracting the resistance/resistors to change discharge rate. Will be building one like this.
In regards to the cooling issue, on my resistor banks, I've just submerged the entire assembly into a Tupperware container full of water. I've only done it with ceramic resistors though so I'd be wary with those metal ones. But just a possibility.
You have to effectively run a 1s balance lead to the balance input section of the charger. It doesn't work without a balance lead because that's how to charger monitors pack voltage. Yes I know there is nothing to balance but you still need it. Trust me.
negative lead to the single cell's negative side, and the next 1s lead to the positive side of the battery. you will have all other leads unused. the x6 is a 6s charger so you have 7 wies toal, 5 wires unused
Hey Wil, great video, but I;m not able to get mine to discharge. I have all the connections correct, i know that but can you please tell me all the configurations/settings on the charger? Everything from input source to Z... Mine discharges but only at 2.~ amps, the bank doesn't kick in.
you ask about 1s packs... its really simple. make your self a 1s balance plug. I used an old servo plug, solder the black wire to the ground and both the remaining wire to the positive. now just plug it in like you do your 2s wires. making sure the black is in slot 1. I use this to charge my 1s batteries and now I get the IR readings on my 1s batteries.
Hey will, Awesome video...had a quick question. I’m doing the math and for a 4s pack I’m coming up with 100W 2ohm resistors (5 total) to discharge 4s lipos at 30amps Is my math correct there. Thanks in advance!!!!
This method works fine, but you have to calculate the resistance you need based on the pack voltage and discharge rate. Then you have to set the charger at the correct amperage for the resistor bank you have. If you don't, the charger will attempt to discharge at your higher rate, but it will not work and eventually revert back to the 30 watt maximum for the charger's internals. You must do the calculation first, and in all likelihood you will have different banks for different cell counts.
Hey Will, GREAT video ! Can I ask what ‘wire’ you used to connect the resistors to each other ? I like the idea of the solid core wire to keep things aligned and secure.... Thanks !!
@@brandongriggs2760 You have to set the discharge rate higher. Search for videos on youtube and there are tutorials. Try Duo460 as a search term, and discharge.

Thank you for this. I was wondering how the connection works. I'm not sure I understand electrically how it's working though.
you run the pos side thru the orange resistors. and they heat up and take out power.

@@eksine I'm sure he made a final soldered connection. This is for testing and to show you what effect each resistor has on the discharge.

what about mineral oil? Like with computers?
Where do I get the connection rod to connect the resistors together? What do they call them?
any Home depot store. a simple brazing rod ir alum welding rod will do.
Wow this is MacGyver level. Awesome stuff. I also noted that it could be daisy chained if you wanted more, really cool stuff man, grats.
its not macgyver anything. this is exactly how the charger is intended to be used
Awesome little discharging technique! Keep up the videos, I just subscribed 😎🔋
What setting for your charger I have 2 chargers and both ramp up to discharge at 30amp for about 4 seconds then drops back to the std 4 amps
yea ok sure, but what settings do you have your charger set to. no extra discharge enabled?
What is the purpose of high amps discharging lipo battery 🤔
As for the 1s battery just make a balance line with just using the positive an negative wires no 3rd wire
Thanks for a great video!!!
My question is that do you have to disconnect the resistor pack to charge the battery??
Yes!
Thanks for the video! Well done! Great switch you engineered there! :) Liked !! Subbed!
This might be a noob question, is the x6 being powered by a normal power supply whilst its being discharged?
yes
Thanks for sharing!
In Order one today 👌
Keep the black wire were its at but move the positive wire to the port next to negative wire an thats how u get a balance wire for 1s
Have you figured out the 1 cell dischaging yet?

Hi, when you cycle the lipo, you can let the resistors pluged for the charge mode?

Have you change your settings on the "discharge" mode? I think the default setting is at 3 amps.
Brad, I'm having the same issue, did you ever find your solution?

Hello. I want to unload 4s to 6s. what do I have to buy for it. you can hardly see what they have accepted as resistance.
I like to make my own resistor Bank. what kind of resistors did you use to make yours?

2.82 ohm, so about 3 ohms and you would need 5 for 30A, yes
I have the same icharger x6. Question will the charger stop discharging at voltage cutoff point?
Yes it will stop at the voltage point cutoff. You set that in the charger.
how many ohms are the orange resistors that you are using ? thanks
1 ohm
@@themotofixerycan I use a higher ohm

I wired it up the same way and did not work
Same here.. i used the same everything and it only bumped my discharge up to 4.8

Would have given a thumbs up if the title had stated watts instead of amps. Since watts are the actual limiting factor here.
That is a very inefficient and in effective cooling system you constructed on that.
Yes it was just for testing
this guy is saying numbers that the charger isn't even showing, he doesn't know how to read numbers
Are the bullet connectors XT60H?
Yes
