iCharger and 40 amp discharge resistor bank

[@matthewcoleman9486]

I finally ran mine a few weeks ago. I was able to discharge at around 5-6 amps on a 6s 4500 battery. I believe we are limited on that due to the input voltage to the resistor bank. It's my understanding that the fans can't handle more than 12 volts.

Does this also work with a 1S lipo where there is no balance lead connected ? According to the manual it needs to have a balancer lead connected but off course with a 1S there is no balance lead. If you don't have a 1S lipo could you try if it works with the balancer board disconnected ? I want to buy one off these for testing my 1S and 2S lipo's but would like to know if it will work with 1S.

Hi there! Have you found out if its working with 1s lipo?

[@roberttruesdell6151]

Why do all those lipos have servo plugs on them as well?

[@christopherburt4463]

Those fans should be hooked up to an external power source. As soon as the batteries are done and the icharger turns off the second channel. This is going to cause the resistors to heat soak and shorten the life of them. Hook them up to the power supply for the icharger.

I see what your saying, we don't build the resistor banks. For our install purpose we use (2) 93mm squirrel cage fans with a independent power source. Please watch this video. kzbin.info/www/bejne/r2O1ZXWkd5pmiLM

[@matthiasurankar6354]

What value resistors are you using on that load bank? I am trying to assemble the pieces to build mine and I am struggling to find any real info how to build those. Or where did you buy yours at if its pre made?

[@kylecashwell1059]

These were sent to us by our customer, I'm not sure about any specs.

[@heardandtested]

How do u know the capacity of each cell after after discharging the battery ?.

[@BisMaxx]

Did the resistor bank feet create those burn marks on the wood? I guess its not safe to sit it on an unprotected surface?

[@kylecashwell1059]

That is my soldering block, I was not sure how hot the feet would get so I went with the wood to protect my assembly deck (Trunk liner on 1/4" plywood)

[@darumaprb8500]

how you have the resistors in one plug and the batteries in other

[@BisMaxx]

found this guy on Ebay for $80. Nice craftsmanship. Do you happen to have a video tutorial on how to setup the charger?

[@BisMaxx]

I noticed you run your discharge voltage at 25V. Isn't that harmful for the 12V fans on the resistor bank? I am able to get my resistor bank to discharge now, but with a setting of 12V it is only able to discharge at a max of 12A??? Why is that? I was reluctant to try to raise the voltage setting, but when I did, I was able to draw more amps. But I am reluctant because of the fans on the discharge device. I do not want to damage them. Any help is appreciated.

[@kylecashwell1059]

I was discharging at 8.343 vdc at the peak voltage. The settings in the charger are what the manufacturer suggests. I went with the 40 amp to get a worst case temp reading.

[@BisMaxx]

I see your screen reads 25V. Isn't that bad for the discharge unit? The 12V fans won't get fried?

[@kylecashwell1059]

That is the max settings. A 2s lipo wont reach 25v. I'm just setting the iCharger to the settings recommended by the company that makes the Resistor Pack. And as for your question, yes, if you put 25v into a 12v fan its going to be a bad day. But we have a solve for that also.

[@BisMaxx]

I am working on 4S packs. I do parallel discharging.Kyle Cashwell

[@darumaprb8500]

looks nice

[@gangstafish25]

How hot do the wires that are plugged in to the left bank get?

[@heardandtested]

Can i discharge with the icharger 406Duo at 30a without the resistor bank?.

[@kylecashwell1059]

140W

[@wrxsavvy]

Kyle, can you share the specs on those resistors? 1ohm 100watt?

[@kylecashwell1059]

+wrxsavvy I believe so, Customer sent us these pre-made to install in a custom charge case. I needed to know the temp for design reasons.

[@wrxsavvy]

+Kyle Cashwell (RotaryWingRC) thank you. I can't see this going in a case unless the case is compartmentalized with a heat barrier. the service you provide is incredible. From a customer I wish you all the best.

[@kylecashwell1059]

You can see the build on our FB page for the cases. Rotor Craft RC

[@jpp2422]

Do you need to discharge the resistor after? or does it just soak up the power?

[@wouldntchuliketoknow8468]

A resistor cannot hold a charge. It converts the energy to heat.

[@vityok_xxl4741]

Why I need use discharge resistor bank??

[@kylecashwell1059]

The highest amp current you can discharge with a 4010 duo is 130 watts. This lets you do a full 40 amp, the RC Car guys use this to condition their batteries before a race.

[@superjoint57]

HELP!!!! While discharging with the same set up you have (iCharger 406 Duo & exact resistor bank), the wires for the bank got so hot the solder came undone on the lead at the charger!!! What can I do to deter this from happening again?? Thank you!

[@kylecashwell1059]

I would contact the company that you got the RB from, that is a issue....

[@gangstafish25]

My resistor got to 170 degrees

[@importryderify]

buy from progressive RC better

[@kylecashwell1059]

We just purchased a competitor of PRC last week, We will have a complete new line of cases coming soon.
