In this post we’ll review the best battery in the whole market to you. It’s iSDT model D2.


First of all, if you don’t know iSDT ( I’ll make a quick explanation for you; as I said iSDT produces qualified batteries but beside this they produces parallel adapters, power supplies, battery testers and products like these. As you can see they tend to the power part of the hobby world and as I follow their products for a long time, they have success on it.

Let’s talk about the D2 that just delivered to me. For a quick look this product is incredibly compact, I mean even if the power supply is inside of it and even if it has 24A charge capacity it’s smaller than you expect and it has lighter weight than you think.

On the delivery box it’s written 10A(20A) but it gives 24A power. In older product informations it wrote as 10Ax2 but in the latest ones it’s updated as 12Ax2.

Official Announcements

  • Input Voltage: AC 100-240V
  • Owing to that it’s AC we have gotten rid of carrying a power supply trouble. Frankly it’s a real advantage for weight and place.
  • Charging Current: 0.1-12.0 x 2 – It can give every output to 12A. In this way you can charge many batteries with parallel adapters. For a simple example if you give 2A to one battery, you can charge 12 batteries just in few minutes.
  • Discharge Current: 0.1-3.0A x 2
  • Max. Capacity of Charge: 200W
  • Max. Capacity of Discharge: 5W x 2
  • Balanced Current: 1A/cell x 2
  • Balancing Cell: You can charge with balance your all batteries until 2-6S x 2 – 6S (25,2V)
  • Supported Battery Types: √ LiFe/Lilon/LiPo/LiHv (1-6S)
    √ NiMH/Cd(1-16S)
    √ Pb(1-12S)
  • Screen: 2.4〃320×240 IPS LCD
  • Working Heat: 0 – 40°C
  • Storage Heat: -20 – 60°C
  • Dimensions: 120 x 108 x 70 mm
  • Weight: 510g – Actually it’s 550g without cables.

Advantages +

  • It’s so good that it can work as AC beacuse of the space acquisition and it saves you from wasting money on extra power supply.
  • It has half price of the other products that has the same quality with it.
  • You can charge 2 batteries at the same time and if it’s a special battery that you charge, you can also setup the output voltage different one to another.
  • LiHv support. It’s not avaible for lots of charges.
  • It shows internal resistance, as you all know it’s so important for you to interpret the battery status. And not avaible for every product.
  • Easy to use. We’ll be explaining to you with pictures in the following parts of post.
  • You can charge your phone quickly because of the output that is 5V 2A

Disadvantages –

  • Inside of the box there’s nothing but a charger and a cable. A cable that turns XT60 to another connectors would be amazing. I mean it’s the higher model of the brand you know.
  • AC cable holder is divergent to Turkey. You have to use a little transformer to to make it usable. It’s not a big problem but the cable holde could’ve been eligible.
  • There’s no input for DC, I mean yes, it’s so good that it has AC input but in the area you could’ve charge it from car accumulator if it had a DC input.
  • In 1S (3.7V) one cell batteries you can’t see internal resistance.


iSDT D2 has really easy usage. Let me explain you:

When we press on the wheel we’re being able to choose the operation that we want to do and as you can see on the right picture, on the screen you see the information of the battery in CH1. If there’s no operation the menu’s color becoming grey.

If we press on the wheel again it turns out the menu that we can do our setups, we are making the setups that we want by turning the wheel.

Explanation of the Menus:

Select Task – The menu that we choose whatever we want to do. We’re able to choose Charge, Discharge and Storage modes.

Battery Type – We can choose the type of the battery we’re going to charge from here. LiHv, Lipo, LiIon, LiFe, Pb and NiMH/Cd are able. When you choose the LiHV cell voltage otomatically setups as 4.35V and it maximum rises to 4.40V. As the same, Lipo is put-up as 4.20V and it can max. rise to 4.25V.

Cell Voltage – You can use it for special batteries. As I’ve just metioned there’s put-up voltages for battery types like LiHV.

Cell Count – We choose cell number of the battery.

Current Setting – Charging current can rise to 12A for one channel. I tried it an yes it is rising but just for a battery it’s a real number. We can use this power to charge it more than one with parallel adaptor. About parallel charge I’ll publish another post.

Start Task – For starting the operation (charge, discharge, storage).

When we choose start task, the operation is starting and the cell values, the current and the charge/discharge mAh values can be seen in that moment and with turning the wheel you we can see the internal currents.

If you want it to show internal currents you need to charge it on a specific mAh value.(80~100mAh)

When the screen goes blue you can see that charge status is about to finish and when it goes green you’ll see that the operation(charging) is over.

The usage is that easy 🙂


The battery is successful to achieve the values that they promise in product information. I haven’t experienced any problem yet. Cross between to channels, settings, see and setup the internal currents are really relax to use.

If you want to charge all of the batteries you have without any problem while using, you can buy iSDT D2, I litterally suggest you this. If you want anything cheaper than this I can suggest you iSDT SC-608. If you wouldn’t be able to find this in storage (they’re not producing it anymore) iSDT Q6 Plus model is for you.

Where to Buy?


(If you ask from Facebook for a discount they would return you. You can say we came from the examination of product in :))


iSDT PC – Parallel Adaptor (If it’s not opening try it with vpn, it’s not in the storage of Turkey)

iSDT BC – Battery Control Device until 8S
