Chargers

I have been using an old Nitecore Intellicharger D4 for years. It has served me well other than being very slow to charge.

I would like a four bay charger that charges fast and has the ability to show battery capacity and voltage. I only have 18650’s at this time but would like the option to charge other batteries as well.

I have a large collection of 18650 batteries with no way of telling their condition which has me wanting a new charger.

The Xstar VC4s seems to be a good choice and is very economical but I don’t mind spending a little more if required.

I haven’t found many chargers on lygte-info that meet all the requirements below.
What do you recommend?

  • 4 slots
  • Capacity and resistance measurement
  • Store function (important for me)
  • Must fit protected 21700 or at least button top 21700
  • Must fit at least two 26650 and two 18650 at once
  • Manual selection of the charging current
  • Does not overheat
  • Nimh charging possible
  • 12V power input (not very important)
  • About $50

Mainly used for NiMh like Eneloop or Ladda, but with the extra to use it with 18650.

I’ve watching Lii 260 and 300. I would like to have Miboxer C2 4000 or Allmaybe TC2 but it’s impossible to find.

I don’t care even if it’s only Nimh, but something reliable and with analyzer.

Yes, i know there is Lii 500 but i’m looking only 2-bay.

I noticed the UMS2 cost nearly double the price of the UM2. So, what are the differences and is the UMS2 worth the extra cost and why?

 

Thanks.

Miboxer C2 charged battery to 4.5V! What to do with this charger?

Chargers

My Miboxer C2 charged a Golisi S43 battery to 4.5V instead of 4.2V. I charged two batteries of the same type. In the first slot the battery charged around 7h to 4.18V and 3700mAh. In the second slot the battery charged for 8h to 4.5V and 4500mAh.

This dangerous charger happily showed he has charged it to 4.5V! I didn’t even know this charger could go above 4.2V because it is not specified for Lipo batteries or anything with higher voltage. I didn’t believe my eyes first but I verified with the multimeter that it was really 4.5V. I immidiately discharged the battery in a flashlight to safe 4.1V.

The charger has worked fine for 2 or 3 years apart from the USB output which stopped working. The warranty is no longer valid so if I knew what caused this failure I could attempt to fix it myself. I didn’t use the charger since a month because I don’t trust it any more. Here are my questions:

What should I do with this charger? Can someone maybe explain why it charged the battery to 4.5V and how this could be fixed?

The Golisi S43 is relatively new, this was the second charge. Did it suffer any permanent damage from the overcharge and is it still safe to use?

Hi, I just bought a new Titanium MD-1600L battery charger. I noticed underneath the charger, it says it has an input of 2.1A, but the power adapter supplied only has an output of 2.0A. Do you think I should buy a new power adapter?

Hello,
I am looking for a charger to charge my smaller cells. Usually AAA’s or 10440’s. All of my current chargers will charge them, but there is always some fidgeting to get them to work. (usually a piece of paper under the battery) I’d like something for these cells that is more of a drop and go. Any suggestions would be appreciated. I currently have a MiBoxer 8-Bay, XTAR VC4s, XTAR VC8, and a Zanflare C4.
Thanks

Hi

I have an Xtar VC2, it seems to work well enough but I would like a charger that is capable of charging to 4V rather than 4.2V, with the intention being to charge to 4V after battery use, then top it off to 4.2V shortly before I need to use it. This is what modern macbooks do to prolong battery life.

Are there any good quality chargers that can set the target voltage?

Thanks,
Mark

Charger with auto current selection or manual current setting ?

Take simple operation into account firstly, guess some of you may choose the charger with auto current selection. Just upon your inserting the battery, this kind of smart charger can make intelligent detection for the battery type, battery resistance and input power, then to select suitable charging current for the battery. Really easy to handle.

While, some people tell that they like more “gentle current” slow charging for small batteries, and fast charging with higher amp setting to save time on the trip. So they prefer being able to set the current manually rather than auto detection. And the charger with manual current setting gives more current choice according to users’ different demands.

And here, you may consider if there is a charger with both automatic detection and manual adjustment? Actually, there is xtar VC8 charger combining them. It can make intelligent charging, also have five optional currents (3A/2A/1A/0.5A/0.25A) for users to choose manually. And based on your preference, do you like chargers with auto current selection or manual current setting, or both?

A 18650 battery is charged up to 4.2V on XTAR X4, why it doesn’t show FULL?

A customer told us he charged his 18650 battery up to 4.2V on XTAR X4 extended, but the charger didn’t show FULL (still at 80%) on the screen. Then, he moved the 18650 battery into another slot, and it immediately showed 100% and FULL. He asked: Shall consider the 18650 fully charged at 4.2V independent of showed percentage, or wait until the screen shows FULL? Did his X4 charger display inaccurately?

Actually, his X4 chargers still works fine. As there is 1% accuracy error of the charging cut-off voltage on each slots, the cut-off voltage (4.16~4.24V) varies slightly between different slots. If the cut-off voltage on one slot is 4.16V, and we assume his 18650 battery’s real-time voltage is 4.18V, the charger will judge the battery is fully charged and show FULL, when putting the battery in that slot. While, if he move the battery to another slot with cut-off voltage of 4.24V, the charger will charge the battery for a little longer time, then cut off. But please don’t worry, the judgement accuracy error is very small, and it will not affect the fully charging of the battery. As XTAR charger can intelligently judge a battery is full-charged or not, if you check the “FULL” on the screen, it means the battery gets fully charged.

As for the reason why the charger doesn’t accurately display the charged volume, the charger shows the percentage of the charged volume to be 20%, 60%, 80%, 100%, and it can’t show the accurate percentage like 98%, 99%. Take above customer’s question for example, his 18650 battery wasn’t charged fully, but almost (e.g. 95%). So it remains at 80%. When the battery is fully charged, the screen will show FULL and 100% in charged volume percentage.

Currently using a Xstar PB2 with 2×18650 for a travel charger and powerpack. Actually very happy with it but I want to transition my travel light to a FM 18500 I built to allow for dual fuel use. The PB2 will require a battery spacer. Are there any similar charges that will work with 18650 and 18500?

parallel battery chargers

Chargers

Hello Everyone,
I am new to this site and this is my first post.
As a part of my project, I want to charge different chemistry of batteries using buck controllers with same input supply. Then the batteries are connected in a manner that to step up voltage using boost controller and it is then connected to common load.

Suppose, a power bus of 36V is supplying to the two charge controllers i.e., buck controllers which are connected in parallel. Then at the output of each charge controller a battery is connected to charge.
Charge controller 1 is connected to Lithium ion 12V
Charge controller 2 is connected to Lead acid 9V
Note: Power supply of both charge controllers 1 and 2 is same i.e, 36V power bus.
Now in this design the batteries are connected to the boost controllers for step up voltage to 24. Two batteries two boost controllers.
Boost controller 1 is taking supply from Lithium ion 12V and steping up to 24V
Boost controller 2 is taking supply from Lead acid 9V and stepping up to 24V
Both the boost converters are connected to the common load bus using ORing controllers.

My doubts are:
1. Can the charge controllers connected in parallel with different outputs? Generally we connect charge controllers in parallel to double the current with 1 output but in my case different outputs. How can I control this process?
2. After charging the battery to its rated voltage, how can I control the charge controller?
3. Here if I use buck or boost converters, what kind of voltage control strategy is implemented either voltage or current? Generally, parallel converters operate with current control but I had different outputs there is no connection between the converters just an input terminals of same power bus 36V.

Can some one please guide me,

Thanks in advance.

Hi everyone, I am building a massive 16-18kwh lithium battery pack using old modem batteries for a solar array and am looking for a good charger to spot test some batteries. I bought a 16 bay cell docter/megacell charger but I am not sure it is accurate and I am a little concerned that I wasted my money. Some cells test at low capacity and then I stick it in my xstarVC8 and they test somewhat normal, then I stick them in my hobby charger and they test even lower. So I am looking to gauge accuracy here, any suggestions?

Why the VC4S doesn’t show number IR when batteries are fully charged?

Chargers

A customer told that he got some 18650 batteries fully charged on the VC4S, then tried on mode IR, but the charger didn’t test the batteries’ internal resistance, nor show the IR data on the screen. You may have the same question about the IR testing on VC4S charger before. Let’s figure it out.

Our chargers adopt the direct current load method to test battery internal resistance. It means to apply a little bit larger current to the battery for a short period of time. Based on the voltage’s change of the battery, also together with the applied current, it can calculate the DC internal resistance of the battery. If the battery gets fully charged, in case of over-charging, the charger won’t test internal resistance in order to protect the battery. Besides, when the adapter input current is lower than 700mA via the charger, which is insufficient for internal resistance testing, the charger doesn’t test IR either.

Any thoughts and opinions are welcome.
