Dont forget that these resistor banks run hot! Always be careful when using one, and always make sure the fans are running or you will be looking at a nuclear meltdown.
I watched your video and it was very informative like the lot we like to know where I can get one of those resistor packs how much and how do you take PayPal and approximately how long does it take to ship one to I would say I live in Northwest Ohio thank you very much
7 year old video but sooooooo good. Thank you for helping me setup my new discharger!!!! Super helpful. Can’t thank you enough 👏
Glad it helped! 👊🏻
Thanks!, this is one of the few videos that explains setting this up instead of just showing it working.
The charge cycle is at 40amps two?
Yes 40amp charge and 40amp discharge
Just finished mine and this video was a great help. Thanks mate
👍🏻👊🏻
Way helpful! Thanks man. Was wondering how to set up my charger to do this. Thanks again
Thank you for the vid! Love vids like this that are straight and to the point! 🤘🏻🤘🏻🤘🏻🤘🏻🤘🏻
Thanks was awesome made setting this up on my new 406 a breeze👍
Thank you so much for making this video!
🙏🏻👍🏻
Can this charger charge / test a 100ah 6 volt Ni-Cd batt?
Great video.. just set up my 406 DUO.. thanks..
Is there a step to set the low voltage limit in the discharge cycle? Great video!
@@polizei16 low voltage being cell voltage when the discharge cycle is complete?
@VoyageRC yes, is there a setting for voltage so that the discharge cycle ends at that point, say 7.6, and then switches to charge?
@ you can set the “cycle” how you want and it will run a discharge and then charge. You can change the cutoff voltage or leave it at the default based on battery type.
@@VoyageRC very cool, thanks for clarification. I'm waiting on getting a dx6 in the mail is why I asked.
@ glad to help. Charge safe my friend 👍🏻
Charger is badass
Just sent you a message about getting one of your power banks discharged power banks but I'll be discharging one cell batteries for paying car racing spec racing Will this work with a one cell battery thank you
Great video !
Do you have a link for the power supply ? The one on the description isn't working any more.
Nice VDO. I'm going to buy this charger (used). If I discharge with resistors bank like you by use a bad battery (very different of IR value of each cell). will this charger protect each cell from volt going below than setting and completed with balance ?
The charger will do its very best, however, if the battery has a bad cell then things can go wrong. Always keep an eye on the battery while charging.
@@VoyageRC Thank you so much.😀
Hi there. Great video yes. I just don't know and you didn't touch on what the percentages for end current. what does that do?
Not much
Do you know if it’s the same setup for a newer 456 / 458?
I believe so, however I have not used the newer versions.
Hey what is ohm?. I want yo buy 5pcs of resistor but don't know which ohn i should choose. Please need your help
Do you sell the discharge bank anymore?
I am currently out of stock. I am in the process of manufacturing another batch with a better cooling design.
Can you please tell me what you used to ‘attach’ the heat sink to the resistor bank ? Thanks !

Should the pack be fully charged before starting this cycle?
POWERITE ELECTRIC-ELECTRICIAN in order to gain the benefits, yes.
After your race what do you do to charge (40amp?)before you complete the discharge/charge as you explain in the video. Thanks.
Nothing on your eBay page. What are the specs of the resistors you are using ??
can you explain what and how is pulse test takes place in this charger
I'm getting back into racing, and I have to say -- this is fascinating. It kind of goes against everything I've been reading about proper LiPo charging/safety. I'm curious, what do you think the realized power gains are? Are we talking 2-3% here? More? Not sure how you would really test this other than "feel".
Anyway thanks for the video!
You definitely feel it. There is no way to quantify it. Thank you!
Internal resistance directly correlates to max discharge. A DC IR test is the way you quantify any increase in performance of a battery
Have you used the extra discharge feature ? Its a resistor in series on the positive side of the battery , it only requires 1 channel.
I have exact same set up battery and all. I put the battery to Storage mode at the end of the day. It roasted my charge cable. Do I need to set up separate set up for storage mode???
You dont need to, but your battery would thank you for a lower charge/discharge rate. This shouldnt have fried your cable. Its less abuse than a normal cycle.
Could you use this setup to discharge a 1S battery with 40A ?
Reason why i ask is that the manual states that the balancing board needs to be connected for regenerative discharging and off course with a 1S lipo that is not possible since it is only 1 cell.
Has not been tested on 1S
I followed your instructions and my pack discharged at 40amps but when it starts the charge portion after about 5-10 seconds it stops and says "Error 0701 Output over current (+). Any ideas of why? TIA
My 406 duo says the exact same thing.In charge mode the highest I can go is 37.9 amps.Power supply is a 1250 watt servor.Thoughts by anyone to fix this issue?Thanks for any input.
catlover After playing with the settings I also figured out it works too with 39.7 amps. I contacted iCharger support in the US & they said flash the firmware. I updated it to v2.18 & same error. Contacted them again & they said it would have to be sent to OEM for repair in China.
iowarctracks I'll try the 39.7 tomorrow.Thanks for the info bud.If I have to send it to China I'll prob not worry about it as other than that I really have no problems now knock on wood.
Just an update for you and anybody my left port only will go to 37.9 charge rate before it kicks off so I tried the right port and I can charge and discharge at 40 amps with no issues.My suggestion is to try both ports and see which is better for you.Good luck and happy charging and discharging.
Got a question. On my charger on the regenerative channel it says 40amps but on battery side it says only -8 amps what am I doing wrong it's a 4010 duo btw. And power never went over 200watts on bank side
How my ohms do the resistors have?
how do you change the on screen temp from celsius to Fahrenheit ??
It should be in the settings menu
compliments for the video very nice!!
i have a question can you tell me the parameters
of the resistence?thank you
100 watt 1 ohm resistors x5
Thanks for the walkthrough!
Should you make a charging profile as well for getting that pack charged?
You can set it all up on the same profile. 👍🏻
@@VoyageRC oh I see, so you can just go to charge. Then when it’s done you select cycle.
@@smcarmel yes sir. Just select what you want to do for the battery. Makes life a little more simple.
For sure, makes sense. And 40a is okay? I feel like 20a may do the same thing no?
@@smcarmel as long as it is a good quality battery. You will get the most benefit from a 40 amp cycle. 20 amp will be easier on the battery and pro long its life.
Question, I have purchased the icharger 4010duo and have been able to discharge battery packs using the charger itself. So what is the advatage of using this setup over the charger itself. Hate to feel like im doing something wrong or missing out on something, thanks.
Using this setup will allow for faster discharge. The charger itself can only handle about a 10amp discharge. Using the resistor bank ups the discharge to 40amps.
Where do you get the fans that you have attached to the resistors??
How hot do the wires on the battery side get? Mine got really hot. My discharge bank was 170 degrees.
Battery side wires are 10g and stay pretty cool. Just get a little warm
Great video and got my icharger 308duo setup in no time. One question, how important is it to enter the mAh on the discharge programming? I currently have it set to ignore, will I damage my packs?
It should not damage your packs.
Voyage RC thanks. Guys at the track that have ichargers have it set to ignore because they think that if you have it set to a specific mAh, it could stop before proper voltage.
Can I discharge at 30amps instead
You can discharge at any amperage up to 40 amps.
Im looking to made 6S resistor bank to discharge your n 40A with 4010 duo ! Can I made this with 100w resistor? I’m calculate around 1000w
10x100=1000
@@VoyageRC yes I know but your cooler and head think will works very well?? Or is normal to stay so hot in aluminum piece , and thanks to reply me and about your video
@@accessor100 a resistor bank generates a lot of heat. Some sort of heat sink and fan will be necessary for cooling.
@@VoyageRC thanks for share! I will made one with this resistors and try to made with 200w too to by less pcs and made smaller bank
With the 4010duo can I turn the voltage up higher then 25v will that be ok?
I would leave the settings the same as the video
Voyage RC ok thanks! Appreciate your response.
how your iCharger doing, mine has been burned after month of working, very unreliable
Atlas .lc I would say a rare occurrence. Mine is still running good.
do you still make these resistors? looking to purchase one but can't seem to find any
Matthew Carvill I currently do not
would my tq 12guage charge leads work with 40amps?
what are the resistor specs? I'm on a tight budget and would rather build my own? thank you
if you don't want to announce to everyone in public my email is butler123454@gmail.com I appreciate your help with my rc habbit
Can i discharge 3S, 4S, and 6S whit this resistor bank? i have Icharger 206B, 306B and 406duo
Sune Olsson higher than a 2s has not been tested on this particular resistor bank. Setup is the same and it will discharger higher cell count batteries. It just might not hit 40amps.
Typically how long would it take to discharge? a 2S pack?
Chad Lintner depends on the size of the pack. bigger mah rating will take longer. my 4250 proteks average about 6 min
Everything works well except you had a 40Amp 9.4C. The highest I can go with mine was 40amp 7.1C
Any ideas?
The C rating is just referring to how many times the Amp Hour rating of your battery. It does not affect the settings. I higher capacity battery will show a lower C rating at 40amps.
ahhh. Thank you sir.
What are you using for your power supply?
Perry Codes a Randy Locken power supply
So basically server pulls that have had bullet connectors soldered on? I just can't understand why people that are most likely technically inclined would pay a 400% to 700% markup for someone else to solder on bullet connectors and wrap it in some vinyl... On top of that, it's a product that isn't going to be warranteed... Blows my mind.
Then dont buy one
I won't. Thanks for the suggestion.

I got some safety alarms going off when I tried this. Same charger.
Thanks for showing the steps! Very helpful for me since I don’t know what voltage to set the resistor bank/sink voltage to. So you recommend to just max it out since the resistor bank doesn’t care what voltage?
You were going to provide a link for the discharge bank. I did not see one.

Heat is terrible for lithium batteries. Cycling from discharge to charge at high rates will damage the pack chemistry. Same goes for reverse charge to discharge, ie charging a pack to running in a vehicle or on a load
Ted Markson feel free not to do this. This is what a lot of the top stock racers do and I have had a ton of questions on how to setup the charger. Yes it is harder on the batteries and you will have to replace them more often. But you also do get a performance boost.
Why didn’t u set ur endpoint to a higher voltage per cell? Wouldn’t that be better
#cheatermode
Hi , I don’t understand why would you want to discharge your battery?
This is a way to generate a little heat in the pack to lower the internal resistance. Racers will high amperage discharge and then immediately charge the battery and go race. This provides a little more punch during the race.
Does this Work with 6s too?
It will, however, it wont go up to 40 amps.
@@VoyageRC ist there a way to let it go up to 40A?
Markus Romeis it would be a bigger resister bank to account for the extra cells.
Would this work on a 308 for onc cell?
In theory. Resistors might need to be slightly different. Setup should be the same.
What about 1s batteries ?
Change it from 2s 7.4v to 1s 3.7v?
@@VoyageRC ok cool but not a 40 amp discharge?
@@AUCRATECH93722 it might still hit 40
@@VoyageRC ok I will give it a shot.
Would this be a regular cycle on race days. Also what type of times for the cycle
@@AUCRATECH93722 cycle before heats/mains. At this amperage it will not take too long.

Where's the lipo sack?
If the battery is gonna go I would rather see it and get it outside. Don’t want it stuck in a bag that will still burn.
But.... why? Aren't you supposed to discharge a battery by putting it in the thing it goes in?
joblessalex what if you crashed it?
that fan aint doing much.. mount it 1 inch above blowing on the heatsink
Only 300 watt discharge. That's nothing for that charger.
Make the damn things take AC voltage and be able to discharge without an addon. Chargers are by far the worse part of getting into RC racing. It's straight up ridiculous
How do u know the capacity of each cell after after discharging the 3s battery ?.
