- Опубліковано 28 сер 2024
- The VX4 can charge multiple battery types including lithium ion 1.5V, nickel metal hydride 1.2V as well as lithium ion 3.7V and lithium iron phosphate 3.2V
It's the first charger that can grade (test the capacity of) lithium ion 1.5 volt cells.

The USB-C port is the obsolete PD2.0. It requests 12V which isn’t available in the PD3.0 standard so many supplies won’t support it. Have you tried plugging it into one to see what it does? The spec mentions it also works with QC3 at 9V so hopefully it negotiates down to 9V and still gets most of the functionality.
First with 1,5V LiIon-testing function but to many Drawbacks:
NiMH-charge only 0,5A
Grading only at 0,3A, a high capacity cell will take much time
Slots cannot configured individually
Charger let only set you max. current, depending on Internal Resistance it will slow you down from 3A to 0,5A
No discharge function
grading actually means charging then discharging, IDK why they didn't just include discharging.
Thank you for the video, i would have liked to see the end result of the discharge test so i can know what that looks like.
Thank you Julain I apreciat this video. I have been looking at that charger for some time now debating it but ive never got one cause I couldn't ever get a video of it to see if it was worth th money. I just ordered mine after putting it off for a good 2 years. Thanks for showing me that it is a decent charger. :) (cool to know it can do nimh, I thought it was just a standard 18650 charger.)
- Will protected (long) 21700 cells fit? (e.g. from Nitecore or Olight)
- Can you add and charge other cells while grading is running in another slot?
- Is it possible to show or see the measured internal resistance? (Most VC4*/VC8* models show it)
That's a really nice charger.
Hi Julian,
CAn you tall me how to get my new VX4 to hold the capacity reading from a test, so when I get back to my desk I can see the reading? It seems to go through endless cycles of charging/discharging, and I never know the battery's capacity from a test.
How about the POWEROWL battery charger??
Not bad for the price if you have lots of battery types.
That looks almost identical to my Amazon Basics smart charger (currently unavailable, so little point in adding a link). Buttons are in a different place to the Amazon one, but the display is the same (I'd swear to it...), and "quite similar" functionality.
Had that one in my basket for some time.
And yeah as far as I remember it looks identical besides the buttons.
Does the Amazon Basics charger do lithium-ion 1.5V?
vc4s difference to this new one?
Well the VC8S doesn't do lithium ion 1.5V cells. I imagine it's the same with the VC4S.
The VC4S can not charger 1,5V LiIon and no LiFePo4. The VX4 can charge NiMH only at 0,5A
Abbreviating "Grade" to "Grad."? Seriously?
Yeah, that is odd.
If I click on the link for aliexpress, it show as low as 31€ + 10€ shipping. If I log in its 46€ + almost 11€ shipping. Nice device, bad policy. Nah thanks. I'm looking for someone who knows the price of their products.
If you live in the EU, then it will add the VAT (moms in Sweden) according to EU rules.
AliExpress is often showing welcome offer when not logged in. These pieces are very low compared to real prices for logged in users. This is very annoying and misleading.
@@kennethnilsson6976 Oh! That might be it. My oversight.
I think if it's "Shipped by Aliexpress", they add import tax. For me in Canada I was angry to see the same thing, but with a laughable $20 CAD import exemption limit here everything gets taxed and Aliexpress quotes a tax-included price. Only lucky Americans get an $800 US import tax exemption.
