I like it. I’ve been wanting to buy one to work with my xtar wp6ii. I don’t mind the slower charging and I discharge my cells to 3v usually so the capacity tester should work fairly well, for a good estimate anyway.

I would have liked a wall adapter but I’ve got enough USB jacks that doesn’t bother me.

Where is a purchase link?

Nice! I’ve been waiting for the discharge testing.

Now adjust that pic to 90%!!! Smile

Will you do a LCD screen charger that will charge LiFePO4 cells at some point?

Wish it could do 1A on every channel.

It would need a fan to keep 4x1A charging cool, and generally that is not appreciated.

Thinking of high current charging without fan: if chargers would be build like flashlights, with heat-paths from critical components to an aluminium shell, that would be neat (and more expensive probably).

Turn the fan on only when needed. I believe the two of four channel charging keeps the cost down (which is a good thing).

That’s why hobby chargers are made of aluminium, but the imax b6 still costs under 30$ and it isn’t so small either.

Are there different recommended links for people living in different countries?
If so a list would be welcome.

If there’s one good link that ships globally, please post that.

VC4 compatible with any USB wall adapters, power banks or computer USB power to make sure you can charge your batteries everywhere and very convenient. And that’s the main reason why we can’t do 1A every channel because of the lower power supply by USB. If you want a charger can do 1A on every channel, XTAR XP4 is a good choice for you, here is the link:

Sorry for the trouble, the first mass production of VC4 has been sold out and not every distributor has VC4 in stock. So we have to know where is your country and recommend the local link for you. Thanks for your understanding.

The first mass production of VC4 has been sold out and not every distributor in different countries has VC4 in stock. We are trying to make more VC4 now to make sure people in different countries can get VC4 with lower shipping cost.

Thanks for your great suggestion.

Question. Is the Ni-MH charging parameter CC Current, or Pulse Charging Current?

At this time, your product link shows CC Current at the bottom of the page, and Pulse Charging Current at the top of the page.

It’s the Pulse Charging Current. The CC current at the bottom of the page is a mistake and we will revise it. Thank you so much! Wilson.

Does the VC4 have the capability to discharge the cells in the charger to test capacity? Or do you have to discharge them to 3.0V seperately then charge to full to get the capacity? I need to know this soon as I have already ordered the CC4 thinking you can discharge/ charge on the charger. If it is not capable of this I am going to cancel the order.

XTAR is from Hong Kong but has authorized distributors in several countries.

America go to either www.xtardirect.com or www.xtarusa.com or www.xtar-store.com These are three different distributors.

Australia go to www.xtar.com.au

South Africa go to www.xtarlight.co.za

Czech Republic go to www.xtarlight.cz

Finland go to www.xtarvalaisimet.fi

Germany go to xtar.de

Hungary go to www.xtarlight.hu

Netherlands go to www.xtar.nl

Norway go to www.xtar.no

Romania go to xtarlight.ro

Russia go to www.xtarlight.ru

Slovakia go to www.xtarlight.sk

Israel go to xtar-il.com

If any distributor sites do not list a new item yet be assured those distributors can obtain the new products from the manufacturer at any time.

Some of these distributors may only sell to dealers so if that is the case just ask them who their dealers are in the respective countries.

VC4 can’t discharge the battery itself and it’s not advise to discharge the battery unless you are professional. We suggest you to let your battery drain to the cut-off voltage by normal use and then recharge the battery in the charger. Hope i can help, thank you.

Question. What is the amps capacity required of the power supply to give the maximum VC4 charge of 2*1.0A? I think this is 2.1A, as you show.

And the second question, what is the amps capacity of the power supply to give the minimum VC4 charge of 0.1A? I am thinking this will be 5V, 0.4A, and will increase the charge time or allow a lower charge amps, possibly to help in the charge of a 10440 cell.

Hi,

I’ve been using this charger for a couple of days and had a question regarding the flashing “Ni-MH” text. It only flashes for a short time, maybe about 5 minutes after the battery is inserted. Does this mean its doing Pulse Charging? after a short time, it then stops flashing.

I’m currently using a 1.6Amp charger (Nexus/Motorola Turbo charger), (got a 2.1amp 5V on order) if I use CH1 & 4 I get .5amp/channel and if i use CH2 & 3 I get .5amp/channel. I’ve not tried all 4 channels yet. I will once this set of AAA finish charging and report back.

Well I have just put 4 AAAs in and its reporting .5amps on each channel, and the “Ni-MH” text is flashing. How can it report .5amp/channel if my charger is 1.6amps?

Output v Input? Is it 1.6a output, or 1.6a input?

Yes, you are right. And VC4 can automatically adjust the input current so you can use any adapters, power banks or even computer USB output. For the 10440 battery cells, sure you can use a lower output adapters to get a lower charge amps to prolong the lifespan of the battery. It’s very wise of you.

Thanks for you support!
When the Ni-MH batteries are inserted in the charger, VC4 will not charge them immediately like other brand chargers, instead, VC4 detect the battery first by flashing “Ni-MH” and then when it recognize it’s a “Ni-MH” battery, it will stop flashing and choose the most suitable charging method. For Ni-MH battery, it will use the Pulse Charging. For Li-ion/IMR batteries it will use real TC/CC/CV charging method.

Some use information for you:
Using different charging method for different types of batteries is very basic and very important. If a charger use the same charging for different types of battery, like if a charger use pulse charging for Li-ion/Ni-MH batteries, the charging curve chart will look like a simulated CC/CV charge, maybe you can get a full battery by that way, but your Li-ion batteries will be hurt and not good in a long run.

For using 1.6amps can get .5amps/channel, i will express your question to our engineer and will give you the answer on Monday when we back to work.

Hope i can help. Thank you.

What are the advantages of the VC4 charger over the Opus BT-C3100?

No one, after lighting a lamp, puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light.

For the question why use 1.6amps can get .5maps/channel. Three conditions, first, maybe the adapter you used is not the same with the nominal output power. The second is maybe your battery capacity is not the same with the nominal capacity and the third is maybe the charging current of deflection of the charger itself.
Our engineer suggest you can provide a video for better and more correct analysis.
Our Email is service@xtarlight.com or sales@xtarlight.com.
Thank you.

Why would anyone needs to “volunteer” his vital stats just to ask a public question in a public forum. Because you are an “Xstarier” extraordinaire or because you are an “inalienable” part of a system that has the undienable urge to voyuer out any possible “dissent”. For those scratching their heads, remember that “A Journey Always begins with The First Step”. An this too:

Bought a VC4 from Xtardirect here in the US. They said they had it and would ship 2 day priority, didn’t go out for a week. Next time I’ll probably order direct from a China vendor and save a few bucks.
Charged a couple of Sanyo 18650s. First one fine. Second one was sensed as a NiMH and indicated charge to 1.55v then showed full. Tried it again for an hour, same thing. Xtar says it’s the battery not the charger, maybe they’re right but in that case seems it should have displayed “null”. I have some Panasonic cells en-route and will try again with those. Jury’s out for me on this charger. Thinking the Opus BT-C3100 might have been a better choice especially given the current Gearbest deal.
