I was looking at battery charger options for the DJI Neo and DJI Mini 4 Pro and I stumbled across a bunch of sales for LIMETA/ISDT chargers.

I bought the ISDT C4 EVO a few years ago.

$63.19 seems like a pretty good price. ATL was $49.15 on 13th May 2025 according to camel

ISDT updated the firmware recently to v2 to add support for cells like 1.5V Li-ion. There's a long thread on BLF where different users talk about their experiences. I still use my C4 EVO occasionally and I think it's worth recommending. That said, you're spoiled for choice these days when it comes to cylindrical cell smart chargers.

LIMETA is a sister company to ISDT. LIMETA is in Suzhou, China while ISDT is in Shenzhen. I wouldn't say that I'm associated. I randomly contacted them while in Suzhou a few years ago and I visited them to see what distinguishes them from ISDT (LIMETA is focusing on power banks and chargers for drones and EDC use).

    This is bit too pricey, whats so good about it other than pretty LCD.

      The C4 EVO goes a bit beyond being a basic charger. It's somewhere between a simple and an advanced charger.

      It gives you more control when charging, discharging or storing Ni-MH and Li-ion cells.

      You can set the charging current, discharging current, cut-off voltage when charging, cut-off voltage when discharging. It lets you select the -dV/dt termination for NiMH batteries (some older cells might need a value closer to 0).

      Once you setup one slot, you can pop a cell into the next slot and it will use the same settings.

      It can automatically detect the battery type too. So it's geared toward simple use while offering some configurability.

      I personally bought the C4 EVO while looking for something to slowly charge small Li-ion cells (10440,16340). I can select a charging current in 0.1A increments. A lot of other chargers have 0.25A as the minimum charging current that can be selected.

      While it's good for slowly charging small button top 10440/14500 Li-ion cells, I found that it is not suitable for flat top 10440/14500 Li-ion cells. The positive terminals in the 4 slots do not make a solid contact with flat top cells. This is something that I mentioned to LIMETA.

        How about Nitecore Smart Charger, usually half the price of this.

        • Tim Mc on 07/09/2025 - 19:50

          Nitecore UMS4 is about $54. It is worth looking into.

          A good all-rounder is the Vapcell S4 Plus.

          • thorpef1 on 07/09/2025 - 20:20

            @Tim Mc: Another vote for the vapcell.
            The highest regarded charger in its price range.

    What is the relevance of this to the DJI devices?

    • Tim Mc on 07/09/2025 - 19:23

      Ah, sorry. The C4 EVO isn't specifically related to drones.

      LIMETA's main products are drone chargers but they also sell products from the main ISDT brand (C4 EVO, N8 etc). This post is only tangential related to the the DJI Neo and DJI Mini 4 Pro.

      I was searching for LIMETA on Amazon Australia to see if they were selling their battery chargers for the Neo and DJI Mini 4 Pro (NeoGo and MC234AC) for an upcoming trip.

      I already have a DJI Min 4 Pro and I was contemplating getting a Neo + spare battery + 3rd party charger (NeoGo). But it looks like the Neo 2 might be released soon.

  • gtech on 07/09/2025 - 19:13

    Any recommendations for a cost effective charger that will do AA,AAA NiMH (IKEA) and potentially lithium batteries (cylindrical cell). Needs to be smart enough to detect batteries but dumb enough that you don't need to plug it into a PC/laptop.

      I have a basic one (Lii-402) and it works perfectly. Only thing I've ever wanted to do that it can't do is try to revive dead Li-Ion cells.

      XTAR MX4 is about $20.

      It has 4 slots, USB-C input, and 4 red/green battery status LEDs.

      There's a toggle switch on the side for the Li-ion/LiFePO4 selection.

      It can automatically detect Ni-MH and Li-ion cells and select the appropriate charging algorithm and cut-off to use.

      The slots are not designed specifically for AA/AAA cells. They are for a wider range of cell sizes. So it's not as nice when putting a AAA battery in. It's not bad, you just have to line up the notches on the positive and negative terminals.

      I was going to say that its a no thrills charger but it does support a bunch of battery types:

      Battery Type | Constant Charge Current | Cut-Off Voltage
      3.6/3.7V Li-ion | 1Ax2 / 0.5Ax4 | 4.2±0.05V
      1.5V Li-ion | 0.5Ax4 | N/A
      3.2V LiFePO4 | 1Ax2 / 0.5Ax4 | 3.65±0.05V
      1.2V Ni-MH | 0.5Ax4 | 1.45±0.1V

      0.5A is not very fast when charging four Ni-MH or Li-ion cells. But it'll get the job done.

      USB-C input worked ok with a bunch of PD and QC power supplies. I didn't have to stuff around with USB-A to USB-C.

      Disclaimer: I reviewed an XTAR MX4 last year.

      • gtech on 07/09/2025 - 21:45

        Brilliant exactly what I was looking for, thanks mate 👍

      • DanielBaird on 08/09/2025 - 20:47

        Can the XTAR M4 use a usbC to usbC cable? My Liito has a usb C input but only works with a usbA to usbC cable, it doesn’t work on a usbC-both-ends cable coming from a usbC charger.

        That was okay years ago but it’s getting annoying..

        • Tim Mc on 09/09/2025 - 01:14

          Yes, USB-C to USB-C cables work with the XTAR MX4.

          I try to use a bunch of different cables and power supplies when testing.

  • Far Cough on 07/09/2025 - 19:53

    i need a new charger for my enloops as they just constantly show a green light and nothing else.

    • Tim Mc on 07/09/2025 - 20:03

      A digital multimeter might be a good investment to check the voltage. $20-30

      Battery test multimeters and handheld LCR meters are much more affordable these days too if you want to check the internal resistance of a cell. You might be able to find a FNIRSI HRM-10 that can do both for $60.

      Then again, the C4 EVO has this built-in. And there are other chargers like the Vapcell S4 Plus or from XTAR with similar features. It's just the internal resistance can vary wildly and the voltage displayed on some chargers may not be super accurate.

      • Far Cough on 07/09/2025 - 20:06

        yeah i use a multimeter and it reads the correct voltage but wont tell me how much mah it has.

        might just buy this and try it

  • WhatsThisThenSlaat on 07/09/2025 - 20:38

    Assuming the XTAR’s don’t compare to this? Just bought the VX4 recently

    • Tim Mc on 08/09/2025 - 00:20

      XTAR VX4 is pretty good. It's less configurable (but the algorithms it uses are good). It supports a wider range of cell sizes. Flat top 10440/14500 fit nicely (they don't in the C4 EVO).

    • techno2000 on 08/09/2025 - 09:00

      There is a new model released recently Xtar VX2 Pro which is a 2 port charger with a few more features compared to VX4.
      I have ordered it from Ali Express and should receive it soon.

  • oz-dave on 08/09/2025 - 01:31

    Is this a C4 EVO or an R4 EVO?
    The pictures show C4 on the first pic, but R4 on the other pics.
    The listing mentions both C4 and R4, depending whereabouts on the page you read.
    Very confusing !!!

    Related question:
    Does anyone have a firmware preference? (C4/R4)
    And if so, why?

  • techno2000 on 08/09/2025 - 07:44

    I have not had a good experience with Limeta R8 Air for 1.5V Lithium ion batteries. I had posted about that deal few months back.
    It was fine for Ni-Mh though.
    Inspite of them pushing new firmware, they could not get 1.5V Lithium ion to charge properly.

    I will be steering clear of ISDT/Limeta chargers in the future.

  • pebbles8 on 08/09/2025 - 15:19

    I bought the Limeta R4 EVO about 2 years ago. I'd probably avoid it.

    • When charging 18650s it has an annoying high pitch pulsing whine
    • It sometimes glitches out, beeps loudly, and resets itself (though charging does eventually self-resume)
    • I have doubts whether the readings from the device are accurate
    • fan is annoyingly loud

    I went back to using XTAR for 18650s and only use the EVO R4 to charge eneloops (doesn't spin up the fan or whine when charging AA/AAA at 0.5 amps)
