My Vapcell S4+ Analyzing Charger photos and observations

Thanks for your answers.

I charged many batteries and on two of them the charger was filling the battery much more (4000 mAh) than the theorical capacity (2700 mAh). The battery was very hot when I removed it from thé charger… I think this very dangerous !

I can’t charge battery on night or when I’m at work, I’m not very confident …

I have noted a similar behavior (both on this charger and my old LaCrosse BC-900) with old worn-out batteries. Maybe try the Cap Test or Repair function on those cells.

Can you give us some information on the batteries that you were trying to charge with this charger? Also, how old are the batteries?

Too bad it has only .5A on 2 discharge slots.

I would of really liked it to have at least 2A discharge on each slot independently.

But then the charger should need perhaps 2 high-volume fans to manage the heat generated at 2a x 4 !

Not a problem; I’m really looking for a multi-slot high current tester. Let the cooling be handled by me.
Most testers I generally found are .5A on discharge test which is utterly useless for any high current cell.
Opuses can do 1A on all slots (and needs modded cooling). Did not find anything better so far.

SkyRC MC3000 can do 1x 2A discharge, or 4x 1A discharge.

I’d really like for the MC3000 to be able to at least do 4x 1.5A, and hopefully make a variant compatible with longer protected 21700 batteries…

Folks:

I bought this charger 2 weeks ago and have put it through its paces. My impression thus far is it does very well. Appears to be accurate. Build quality is “ok”. About standard for the course. My ONLY issue is the power supply. It is noisy. I can hear a constant buzz when not plugged into the charger and when plugged in and charging a cell you can hear a pulsing sound. Not good. Almost too noisy to share my office. I might have to start looking for a quality 12V 5.0A = 60 Watt charger that is quite as this buzzing is problematic for me. Anyone know where I can buy a decent build power supply?

I use this type:

Similar for 5V, 30+A.

@tatasal
Got this charger less than a year ago and it worked great for my needs.
The other day went to charge some batteries and the screen was blank.
Long story short I am looking for a new charger since this one is dead.
Sent email and pm to Neal however got no response if it is covered under warranty.

Dennis of Vapcell, who is also a member here, just said they have 1-year warranty as long as the the damage is not “man-made”.

Thank you for the update, silly question how do I get hold of Dennis?

Update:
Just sent a pm to Dennis.
Thank you @tatasal.

I received my s4plus today.I can't change current. I do what instructions say. Charger says its in 3a current but then goes down to 157ma. Seems like Charger doesn't go into manaul. Can anyone please help. Thanks Jim

.

Did you manually move or set to Manual and still won’t obey?

Can you tell me how to change the current. I can't seem to get the current to change. I can't seem to get in manual mode.

Set to Manual mode while there is no cell in the bay.

Once a cell/s is loaded while in Manual mode, the charger’s “mA” in the Display should blink, then you can press the “current” button to the mA you wish.

so, Im interested in figuring out the IR of my Eneloops
sounds like this is not the right charger for that job:

I don’t think there is currently a commercial charger/analyzer that can consistently show the correct IR each time, not even my more expensive SkyRC MC3000, considering the inherent drawbacks of using “sliding” rails in order to fit various kinds of cells in the bay, tightness of the contact points, etc., etc. that can affect such IR readings, though they can be just about in the ball-park figure and of course, better than no reading at all of the old analyzers that we have.

….and these manufacturers actually never claim that their product can consistently give the correct reading, each time.

However this is the Vapcell IR tester that I have that can “repeatedly” give out the same IR figure almost each time:

thank you
I need education, considering my first analyzing charger

I have noticed that my old Eneloop, no longer produce as many lumens from my AAA Tool, as my new Eneloop. Im not sure if that is due to IR, or loss of Capacity, or something else

is this S4 a good charger for me to monitor the capacity and resistance (at least to tell new cells from old ones), of my aging Eneloops, as well as LiIon cells?

or would you suggest a different analyzing charger, for my application?

I would say that the current “improved” version of the S4+ will be good enough for your needs.
