New HIT? Xtar present VC4S

http://xtar.cc/charger/vcseries/2019/0430/411.html

Good news:

1. Test Batteries’ Real Capacity - charge/discharge (good by Liitokala Lii-500 :laughing:)
2. Storage mode

Certainly interested! Individual display, and it charges NiMH as well… :sunglasses:

I like the capacity test that can include D cells. I’m using an Opus BT-C100 for testing my D NiMH capacities.

But I’m not sure about auto selecting the charging current by battery resistance with no option for manual current selection. Can someone tell me if this is better and why?

This is not too good, unless the algorithm is very smart/conservative in terms of power levels.

I personally only like to charge at 0,5-1,0A depending on the capacity/chemistry of the cell to preserve cycle life.

On the C4-12, if you let it adjust the current automatically, it’ll go to 3A with a 30Q, which isn’t bad, but worse for overall cycle life.

I would never buy a charger that doesn’t let you change the charge current.

We are waiting for the test VC4S from HKJ

Hopefully there is an override using the mode button… Otherwise this might be a deal breaker… ugh… And boy, XTAR is good at incorporating deal breakers in their chargers…

I drive a car with an automatic gearbox, although I could ride a manual gearbox but with a more precise gear selection. I choose the automatic gearbox.

Agreed. Complete deal breaker. Other than the PB2 I own, I don’t think there’s an XTAR charger I’d buy because each one I’ve researched has some sort of deal breaker.

Well, it’s not gonna replace my xtar vp4 dragon+, i need 4 wire IR measurement, and usb output.

I hope if they make new version of vp4+, they increase power to 2A*4 slot, or 3A*2Slot, and use Type C PD for power input and output

Well, the PB2 certainly was a flop in many ways.

And being a good powerbank was not one of them at least.

They should have use type c and not micro usb.

Not a good analogy, charging current is a “set and forget” option vs the active task of driving a car and how driving a manual requires a lot of constant effort and attention.

This is more like turning “active eco” or throttle response to different options before starting your drive.

I’ve heard some negative feedback about the PB2, like not being able to charge low-draw items. But I’m curious of the many ways you find it to be a flop.

No, BlueSwordM is asking for an automatic transmission that has a manual shifting mode for when the driver wants to take full control and override the normal shift logic, like those often found in luxury cars.

Based on my experience with a TC2, I’d agree. It’s frustrating because it refuses to charge my 30Qs at anything above 500mA, and there’s no way to override it.

But is nice to see more manufacturers embrace the extra power of QC for their USB-input models.

There’s no override button, but I suppose you could always plug the charger into a 1A source.

Nope, no manual override of charge current is a “will not buy” scenario.

For me, I would prefer:

  • 4 bays up to 2A
  • 2 of 4 bays up to 3A
  • Accurate & repeatable IR measurement
  • Discharge capacity measurement
  • Li Ion/NiMh compatability
  • Manual charge current setting
  • 21700 compatability
  • Active cooling that works
  • AC power in

I do not care for:

  • Powerbank
  • USB compatability
  • Fully automatic choices
  • Solar compatability
  • Unnecessary ‘bells & whistles’

I don't think there's a single point here I disagree with. I don't mind slower charge rats as much, so the 3A or higher isn't important to me. I actually currently charge my 5500mAh Shocklis on a 0.5A charger ;)

I used to have access to a lot of goodies at a previous place of work, with a Cadex C7400.

/\ :+1: … We think pretty much alike then…… :wink:

VC4Soclose… :person_facepalming:
