How to setup a resistor bank for 40A discharging

[@thomasweber3559]

Hallo Alexander möchte mir so eine Discharge Resistor Bank selber bauen was genau würde ich benötigen oder wo könnte ich so etwas Kaufen

[@JONESSFCY]

Can you show how to set ip the cycle (discharge first and charge) with defined resting time in between? Thank you again for always bringing valuable info. Loving the “stock” racing related videos.

[@hagberg]

It's fairly easy to do. You need to go into the LiPo Cycle Set-up. Set it do DCGH->CHG, cycle count 1, Delay time - I would suggest 3-5 minutes

[@JONESSFCY]

Got it. Thank you so much

Great video, always great tips .

[@bstearn1653]

In the video at 4:20 you say the resistor bank is plugged into the second channel but earlier it was shown plugged into Channel 1. Did you change it before running the Discharge?

[@hagberg]

You can plug it into either channel (opposite of the battery), the other channel will always be used for regenerative mode.

Hi Alex, on the LOAD side, do you know why the Voltage is higher than the battery side, is this normal? It also shows the Amp on the LOAD side is not reaching to 40Amps as you set on the battery side. Is this because of the resistor bank spec? I ve just made mine and tested it, the reading is almost the same on both page for Volt and Amp, i m wondering if there is something i did wrong with my charger set up or my home made resistor bank.

[@hagberg]

Did you crank the voltage and current limit all the way up as advised in the video?

[@dameetz]

Yes I did

[@jas-FPV]

What resistance is needed ? I guess the charger will apply a CC profile ?

[@hagberg]

@jas-FPV good IR for these types of packs, as measured on iCharger, is around 1.0 or thereabouts.

[@jasong712]

So, these discharges do nothing more but discharge the battery quickly and safely of course?

[@hagberg]

@jasong712 correct, the discharge bank allows for a higher discharge rate than if you would use the charger alone.

I just got a 458duo and it will not discharge with a discharge bank plugged in to channel 2 and battery in to channel 1. My 308duo can have discharge bank in either channel. Do you have any idea why?

[@hagberg]

It works on one channel and not the other? Or not at all?

[@jasonchavis6414]

When I’m at the race track for the day do I discharge in charge every time I need the battery for a race?

[@hagberg]

Correct!

Hi Alex, What is the reasons to cause lipo batteries get swollen😢 We even set the HW speedo to cutoff voltage...nothing less than 3.3v/cell We race 1/8 GTe

[@hagberg]

The main cause is too much load, or when run until too low voltage. Too many heat cycles can also wear our out the battery quickly, some brands seem more suspectible to "puffing" than others.

[@thomsonchong3248]

what is your advice to reduce the load😊

[@hagberg]

@thomsonchong3248 make shorter runs, reduce turbo and boost in the ESC. Shorter gearing.

[@MrBratius]

Will this work with the 406X as well?

[@slappomatthew]

1s balancing is something I will never understand.

[@jorgemalafama7196]

are the resistors 1 oam? or more?
