Yes. I even called TQ Wire and spoke to them about how to connect to the charger using their leads and a 1S battery.

How are you able to use 5 resistors ?? are they all 1ohm 100watt ?? My RL power supply made a weird noise and shut down permanently when I hooked up 5 resistors, it worked fine on 4. Now the power supply turns on for 8 seconds and shuts down I verified this with 2 older computer power supplies, they both worked fine with 4 resistors but burned up with 5

Those little fans are cute and all but don't do anything to cool the resistors down, ended up with a 70mm pcu fan ... keeps the temp at >200F

maybe a lower watt resistor ? trial and error i guess , keeps it to himself so he can sell the resistor banks

Same here 27 amps or so with 4 1ohm 100w resistors

Mopar, If you are using the Discharge+ function, it should not do anything to the power supply itself. It sounds like you have Regenerative discharge mode set instead. This will destroy power supplies like you have noted. Please disable regenerative discharge, otherwise you will destroy every power supply you connect it to. It must be getting expensive at this point.

Marcos.J, The resistance of the wires and connectors can reduce your discharge rate. The wires or connectors must be hot to the touch, yes?

R = E/I = 8.18 / 26.5 = 0.308 Ohms. Your wires and connectors comprise about 0.58 Ohms. Try larger wires, larger connectors, and double-check solder joints.

The resistance of the discharge bank is not a secret. Please read my posts earlier in this thread. Comment #33.

With all of the talk of reaching a 30A discharge rate with the x6 and the required hardware and wiring, I have to ask what discharge rate is possible out-of-the-box?

yes hot to the touch ill try another resistor i do have my regenerative function disable

Dont feel bad, I blew 3 power supplies learning this.
thanks for the link updated the software and I’m just shy of 30 amps I’m ok with that probably just need to redo the solder joints

If you don't already go to rcgroups.com, you should check out their battery forum as Junsi has been active there. That's where they have also posted all the latest FW.

This!

Every race I have ever been reads different, even with Fluke meters

I do this too, ...... weight scales have the same issue

Well I got it to discharge at 29.7-29.9amps so that’s pretty close to 30 amps . Cost me about $9 worth of resistors from amazon and always 1day shipping

fluke meters are calibrated at the factory, but that's only good for 3 years. I highly doubt anyone is sending theirs in for any kind of calibration down the road...

Hey Andy, Regenerative mode is off, discharge rate set to 30A, extra discharge enabled, also have balance enable on ... maybe that's the problem ??

Oh I get it, I have 3 power supplies in the trash I am using 1 ohm 100 watt resistors and running on the latest 2.0.4 beta2 ...

Has anyone figured out how to discharge a 1s pack at 30A?
