For Sale EV Peak CQ3 50Wx4 6A 4 Channel Balance Charger/Discharger & 5 in 1 Cell Meter

You had my attention with the CQ3 in the title, but thought I'd mention your pictures show a CQ2 model, which has a 5 watt discharge limit. A CQ3 has a 10 watt limit, which cuts the discharge time in half..

 

And how awesome is the CQ3 vs. Hitec x4?

 

Before we semi-hijack this thread, I want to say this:
The CQ2, I believe, is on par with the HiTec x4 AC+ model 44167. Both are capable of 5w power dissipation. This is perfectly adequate for the average DIY person who's looking to cycle their modules.

I have (3) of the 44167 models and used them for a while for cycling modules. For someone doing volume, the 5w discharge limit slows things considerably. Jumping to the CQ3 (I have 7 of the CQ3s) or the later 10w model of the HiTec cuts serious time off the cycling. I now keep the HiTec 44167s on standby for other projects.

Now, there are advantages and disadvantages to both.
Both are very programmable for safety limits, current setpoints, mAh charged, time limits, etc.

I love the firmware on the 44167. I can set them to do up to 5 cycles with no further action from me. Regardless of what limit triggers the charge or discharge to stop, it will perform the programmed delay and then start the next cycle. It's just the 5w limit that kills me.

The CQ3 paperwork says it will do the same, but it doesn't. If it reaches the mAh limit, it will, but for any other limit, it just stops. This is true on all 7 that I own. I have mine set to do only 1 cycle, as I do 28 modules at a time, and I want them all to be on the same schedule. I start one cycle at 530am and one cycle at 530pm. I do not know if the CQ2 has the same firmware 'glitch'. Maybe the OP can fill in that info.

The new Hitec model that replaced the 44167 features the 10w limit and I've thought about trying it, but I heard it suffers from some firmware glitches also.

 

Thank you. I'll send you a PM when they start working again.
