Looking for some input. I'm looking to upgrade my charger have a 200w ac charger I'm looking at the dx6 dx8 or 406 duo. I charge up to 6s. Normally 2x 4s or 2x 3s packs. What would the best option. Also best psu to pair with it

Hello

While using the charger this weekend, it turns itself off and on again while trying to charge it on the 2nd channel. On the 1st channel, it gives error code 1602 when trying to charge.

How can i solve this problem?

I want to use the servo features, anyone with experience explain how to wire it up?
TIA

Good day everyone, Had my DX8 for a couple months now and now trying the regen discharge with a resistor bank. I am however having an error after starting the discharge. I am getting a Common-negative connection? Has anyone had this error and have a solution as I am powered off a 12v power supply and 2s battery. I have gone through the manual and settings and cannot find a answer.

"CH1 & CH2 common-negative connection prohibited" ERROR 1404

Thanks

I have a DX6 and I get this error periodically but I've never tried regen discharge. I get it when just trying to charge two batteries at the same time. unplugging everything including input to the charge, ie a power cycle, makes it go away. YMMV

I have the DX6 and am having the same error 1404 trying to cycle with a discharge bank in CH2 and battery in CH1. Would love to get this corrected. Any advice would be appriciated.

The manual also has error 14** deleted from the code list as there is a black line between 13** and 15**. The manual does state the input negative must not be connected to the battery etc negative lines on the outputs which could be the issue here in terms of the error, but mine are not connected either. I have tried changing the setting to accept regen to input as well as this is the only setting that mentions regen but still the same error again. I have followed multiple videos online to see if I am doing something wrong but all setting the same. All videos relate to the 406Duo, The software looks the same so dont know where to resolve this issue.

Thanks

I finally contacted Jun-si directly on their email [email protected] to refer this error to them and they supplied new firmware which resolved the problem. Their reply was within a day so great service.

I’ve been looking for correct wiring configuration for charging and discharging of 1s batteries using a discharge bank and the DX8 charger, DRC sells the cable but they are on several week back order and will not ship out till June 16 as per the website

Recommended firmware update for DX6 and DX8. Supposed to fix reliability issues.

It's from the future, you know it's good.

I have a DX6 and have a couple questions for the experts.

1. I’m trying to set up a cycle for discharge to storage. I select dschg->chg sto. Discharge is configured for 32amp to an external bank. Storage is set to cut off at 3.85V. The problem is the cycle wants to fully charge after discharging. I assume it would then run the storage mode discharging down? The issue is the full charge isn’t necessary, and I want the faster discharge vs using the internal resistor only available in storage. What am I doing wrong here?
2. Can I run a second DX6 off my Fantom 900W power supply? Mostly wanting to speed up discharging and getting batteries to storage at home.
3. If I use the DRC 2s Dual Balance charge lead and want to continue with 1C charge rate I can keep my amps set at 5A? (5600mAh battery)

1. Not sure I follow what exactly you're doing there. In my 406 Duo there are basically three different modes: charge (always charges the battery to what you defined as "full" setting), discharge (always discharges until "empty") and storage (will put the battery to the selected storage voltage and will automatically decide if it needs to charge or discharge to get there - and will use the settings for either as defined in that profile) So if you have setup both charge and discharge modes to your liking, all you should have to do is just set the charger to storage mode and let it do it's thing, instead of setting it to discharge->charge->storage (that would only be needed if you planned on cycling that battery).

2. Depends entirely on how many cells you charge with how many amps. at the same time. Discharge doesn't really put load onto a PSU. So on 900W you should easily be able to charge e.g. three 2S batteries with 30A simultaneously - with power to spare. Just calculate Volts times Amps equals Watts - just remember don't expect 100% efficiency, so always leave some headroom.

3.Technically 5A for a 5600mAh battery is only around 0.9C, but you could run it like that if you really want to. Personally I'd never go below 1S (1S already is ultra-ultra-ultra conservative with modern batteries, so I don't see the need to ever go any lower. In fact I usually don't use less than 2-3C most of the time. Not sure what the balance lead used has to do with it, though? Maybe i understood the question wrong?

1. Thank you. That's super helpful that storage will use the discharge setting profile if needed. So if my discharge uses and external resistor on Ch.2 at 32A then it will follow that setting. That's all I was trying to do.
2. Just wanted to confirm. Voltage calculation should be based on the battery nominal voltage or the 12v of the PSU? I think it's the battery nominal voltage even if charging in series exceeds the 12V PSU.
3. The DRC 2s Dual Balance charge lead looks like a series connection. So I think the voltage increase, capacity increases, and current remains the same; then you would end up charging at the same C? Thanks for the suggestion, I'll bump up my charging rate to 2-3C.

1. At least my iCharger does.

2. I'd use the max, not the nominal voltage. So 4.2V per cell for that calculation - but remember keep some headroom with the wattage.

3. If that cable connects two 2s batteries in series, you'd need to set the charger for a 4S battery of the same size, incl. C-rate. Just make sure you use the necessary precautions for serial (or parallel) charging. You should only do serial charging on chargers setup to balance during the whole charge, not only at the end - otherwise, if you use different size batteries (which you should not with this method), or if you use batteries that vary widely in their charge status (let's say one really empty, one at storage), you could end up with one of the batteries getting charged beyond 4.2V, which can get dangerous. As long as you always watch out for all that, serial charging is not a problem.

What is the most amps you are able to discharge 2 x 2s lipo's at using the internal discharging?

My K2 charger limit is 1.5a x 2 (even though specs are 30w x 2), looking to upgrade
