Review: iSDT Q8 LiPo Charger – All You Needs for FPV?

Review: iSDT Q8 LiPo Charger – All You Needs for FPV?

The iSDT Q8 is the successor of the well-known Q6. At the identical value, the Q8 improves in each cost present in addition to energy, so it’s a significantly better than the Q6 on paper, however is it an total higher charger? Let’s discover out.

Learn extra about methods to choose a LiPo charger for FPV.

There can be the MAX Edition which has 1000W energy and 30A output present. In my opinion it’s an overkill and never sensible, to not point out it’s onerous to discover a matching energy provide for it. The 500W Q8 is greater than sufficient for most individuals, and it’s less expensive too.

The Q8 charger comes with a display protector, handbook booklet and a few stickers. There’s no cable offered.

At 20A output, you may cost as much as 13 typical FPV drone batteries on the identical time in below and hour (4S 1500mAh). This is greater than sufficient for most individuals. The remainder of the specs are simply as spectacular.

  • Charging Power: DC 500W
  • Charging Current: 0.1A-20.0A
  • Discharging Power: 15W
  • Discharging Current: 0.1A-1.5A
  • Input Voltage: DC 10-34V
  • Output Voltage: DC 1-34V
  • Support Battery:
    • LiFe,Lion,LiPo 1-8S
    • LiHV:1-7S
    • Pb: 1-12S
    • NiMH: 1-16S
  • Balance present: 1.5A/Cell Max
  • Size: 80X80X34mm

The Q6 and Q8 are priced the identical, nevertheless the Q8 is far more highly effective by way of specs.

Q8 Q6 Pro/Plus
Max Power 500W 300W
Max Charging Current 20A 14A
Balacing Current 1.5A/Cell 1A/Cell
Support Cell Count 1S – 8S 1S – 6S
Discharge Power 15W 8W
Input  Voltage 10V – 34V 7V – 32V
Size 80x80x34mm 80x80x33.5mm
Weight 170g 119g

It’s utilizing “contact buttons”, which is far more sturdy than bodily buttons. But I personally discover contact buttons are slower to make use of and fewer exact than bodily ones. Anyway you’re going to get used to them after some time, and it’s not a deal breaker in any respect. I do nevertheless miss the curler wheel button within the Q6 although 🙂

On the appropriate, there’s the enter XT60 connector, and micro USB port for firmware updates.

On the left, there’s the output XT60 connector, and stability connector.

Nothing to see on the underside, just a few non-slip ft.

The iSDT Q8 is a straightforward charger, it solely expenses and discharges batteries, there’s no different fancy options like the ToolkitRC M7 we lately reviewed.

Simply plug in a battery to the output, and enter the cost settings, you’re good to go!

Once the charging began, you get to see the enter and output voltage, in addition to the temperature of the charger.

The fan solely begins blowing when the charger will get heat, and the fan velocity will increase with temperature to attenuate noise.

It additionally reveals the inner resistance of the cells, which is beneficial for figuring out the well being of the battery.

When you aren’t charging, maintain down the enter button for 3 seconds takes you to the system settings.

In system settings you may regulate the next:

  • Lowest Input Voltage
  • Max Input Power
  • Backlight
  • Volume
  • Completion Tone
  • Touch Slide
  • Lanugage
  • Theme
  • Keep Trickle
  • Self Test
  • Calibration
  • BattGO
  • System Info

Here’s the handbook that comes within the field explaining methods to use the Q8, however truthfully it’s not that troublesome in any respect in case you have expertise with any good chargers.

After confirming with a multimeter (calibrated), the voltage readings within the XT60 and stability connectors appear to be extremely correct, most likely probably the most correct in all of the chargers I’ve examined this 12 months, I didn’t must calibrate it 🙂 To offer you an thought listed below are some measurements:

Input XT60 Output XT60 Balance
Multimeter 15.14 15.02 3.70, 3.79, 3.78, 3.73
Q8 15.2 15.0 3.73, 3.78, 3.79, 3.70

And it doesn’t over cost batteries both, whenever you set it to cease at 4.20V/cell, the top voltage of the battery doesn’t exceed that.

Apart from the excellent specs and correct efficiency, listed below are different optimistic elements that I ought to point out after utilizing the iSDT Q8 Lipo charger for some time now.

I take advantage of the Q8 often indoor, however largely for area charging similar to I did with the Q6, as a result of it’s compact and light-weight weight.

One factor that folks don’t discuss when reviewing chargers, is the stability present.

If you’ve got a charger with low stability present, it’ll take without end to complete the final 2-3 % when charging a battery with out of stability cells. The greater “stability present” is, the sooner it’ll end balancing the voltages between cells. This is very essential when you find yourself charging a number of packs concurrently, and if the cells are out of stability. The Q8’s 1.5A  per cell is an impressive quantity, in cheaper charger it’s often round 0.4-0.5A / cell.

The coloration LCD display could be very vibrant and readable even below the solar, viewing angle is nice additionally. It additionally provides “darkish mode” within the system menu which is nice for low mild setting and it doesn’t harm your eyes.

To replace firmware, it not requires that bizarre 3.5mm audio jack with serial adapter. there’s now a micro USB port you may simply plug straight into your laptop.

Overall I’m very pleased with the Q8, there are a few issues to pay attention to although.

I want they used the identical scroll wheel button from the Q6, the contact buttons of the Q8 are extra sturdy for positive, but in addition barely more durable and slower to sue.

It’s a single channel charger, which means you need to use a parallel charging board should you have been to get probably the most out of this charger. If you don’t like parallel charging as a result of security concern, you may solely cost on battery at a time, or most likely want a multi-channel charger just like the ToolkitRC M4Q.

You can’t energy the Q8 instantly from AC, you may solely energy it from a battery, or use a devoted energy provide (PSU) which needs to be bought individually. This is what I take advantage of: This is by no imply one of the best PSU, but it surely’s good worth and no DIY wanted, see my overview right here.

You may also get the marginally costlier ToolkitRC P200, it’s solely 200W (100W AC), but it surely’s versatile and plug and play. The least expensive / strongest possibility could be utilizing a server PSU, however that requires some DIY and understand how.
