Charger in use#

The SkyRC MC5000 is pretty big for a four slot battery charger and analyzer!

I can forgive the size due to the awesome display and the fans.

The positive terminals have two notches each. This makes it easier to insert flat top cells without needing to balance them near the top. That said, if the wrap of a cell blocks the negative end then you will need to carefully align the notch on the negative terminal with the negative end of a cell.

Overall, I am impressed with the battery compatibility.

User interface#

The SkyRC MC5000 has two buttons to control it:

  1. A PORT button to select the slot.
  2. A scroll wheel that can also be pressed down to act as a button.

I found the user interface to be very intuitive.

You can use the SkyCharger app for Android and iOS to control the SkyRC MC5000.

SkyRC MC5000 closeup-scroll-button

There are two ways to select a slot:

  • Press the PORT button. The display will change to a screen for slot 1, 2, 3 or 4.
  • Scroll up or down from the main screen. The number 1, 2, 3 or 4 will be highlighted. Press the PORT button or the scroll wheel to select that slot.

From the slot screen, press the scroll wheel to edit the configuration.

Select the Battery Type by scrolling down and by pressing the scroll wheel.

Battery Types:

  • Li-ion
  • Li-ion HV
  • LiFe
  • NiMH
  • NiCd
  • eneloop
  • NiZN
  • RAM
  • LTO
  • Na-ion

SkyRC MC5000 ui-battery-type-1 SkyRC MC5000 ui-battery-type-2 SkyRC MC5000 ui-battery-type-3

Once you have selected a Battery Type (e.g. Li-ion for 3.6V/3.7V Li-ion), select a Task (e.g. Charge).

Li-ion Tasks:

  • Charge
  • Storage
  • Discharge
  • Cycle

Each Battery Type will have a different set of Tasks with different presets. When you edit the options for a task, the SkyRC MC5000 will memorise your preferences. Upgrading the firmware might reset your preferences.

SkyRC MC5000 ui-li-ion-charge-1 SkyRC MC5000 ui-li-ion-charge-2

Once you have selected a task, insert a cell, scroll up, and press the scroll wheel to select Start. You will be prompted with a question asking whether you would like to apply your choice to the current slot or all slots.

If you would like to stop a task early, select a slot and press the scroll wheel. You will be prompted with “Stop Working?”. Press the scroll wheel again to stop the task or press the PORT button to cancel and resume the task.

I highly recommend reading through the Quick Start Guide.

Testing a battery charger and analyzer#

I started by reading HKJ’s web page “How do I test a charger” to figure out how to measure the voltage, current and temperature of a cell in a charger.

This resulted in ordering some parts from mouser to create a shunt to measure the voltage so that the current could be calculated:
30*603-MFR-12FTF52-0R1 MFR-12FTF52-0R1 0.1 OHM 1/6W 1%
1*590-540 540 DB SIDE COP CLAD BRD

I decided to use parametrek’s ble_meters script to record the data from two Zoyi ZT-300AB Digital Multimeters with Bluetooth connectivity.

After assembling the shunt, I tried to determine the resistance of it so that I could calculate the current:
https://www.robotroom.com/Measuring-Low-Resistances.html

I measured a resistance of roughly 9.5686 mΩ using a UNI-T UT139C Digital Multimeter.

The ble_meters script sees what the Zoyi ZT-300AB has on the display.

For example:

The voltage measured across the shunt might be 0.99mV when there’s a pre-charge current of 100mA.

A 300AB that’s hooked up to the shunt will display 00.99mV and ble_meters will have 0.00099 V.

I can use Ohm’s law (V=IR or I=V/R) to determine the current based on the voltage displayed and the known resistance value of the shunt (0.0095686 Ω).

I = V / R = 0.99mV / 9.5686 mΩ = 0.00099 / 0.0095686 = 0.10346 A

In the interest of transparency and to help others try to measure battery chargers, here is a charger_plot.py script that I created based on bmengineer’s RuTiTe to generate graphs showing the voltage, current and temperature over time.

To measure the temperature, I taped a type K thermocouple to the cell with Kapton tape.

DISCLAIMER: My results may not be very accurate because. A 2A charging current might end up being read as 1.95A or 2.05A. There may also be gaps in the data where Bluetooth connectivity has dropped. I restarted tests where too much data was lost.

SkyRC MC5000 test

Tests#

Room temperature: 21 C

I have measured the voltage, current and temperature of various 1.2V Ni-MH, 3.6V Li-ion and 3.2V LiFePO4 cells while charging and discharging them in a the SkyRC MC5000.

The temperature was measured with a Type K thermocouple.

The voltage was measured with a Zoyi ZT-300AB Digital Multimeter.

The current was calculated by measuring the voltage across a shunt with another Zoyi ZT-300AB Digital Multimeter.

The start and finish voltages were measured with a Fluke 117C.

Here are the test results!

I bought two SB2307 18650 3.2V LiFePO4 1600mAh cells from jaycar.com.au to see how the SkyRC MC5000 handles them. The product page mentioned that they can be cycled 2,000 times. Specifications: 2.0A (Peak Current), 1.0 mAh (Amp Hour Rating), 60 mOhm (Internal Resistance), Nipple (Connection Type), 5 second (Peak Discharge Duration), 1.6A (Continuous Current), 3.2V (DC Voltage). There was no data sheet. I found SB2307 mentioned on an Electus Distribution website. I will take the specifications with a grain of salt and be conservative when using the SkyRC MC5000 to charge and discharge the cell.

Charging a protected Li-ion cell#

The SkyRC MC5000 does not appear to be able to activate a protected cell where low voltage protection has been triggered.

I tried to charge a protected 14500 3.6V Li-ion 920mAh cell where a flashlight had discharged it to a point where low voltage protection was triggered. However, the SkyRC MC5000 was unable to detect the cell.

I put another 14500 3.6V Li-ion 920mAh cell with a relatively low voltage of 3.2V in slot 1 and started charging it. I then quickly swapped it out with the other 14500 cell and the SkyRC MC5000 continued charging. This workaround works but it would be better if the charger could apply a low current when selecting Start for a slot.

USB-C Output#

The SkyRC MC5000 has USB-C PD3.0 65W output.

Thermal Images#

I used a Zoyi ZT-R01 IR Thermography Multimeter to take thermal images of the SkyRC MC5000 while charging a Molicel P42A at a rate of 5A.

AC Leakage#

To check whether there is any risk of electric shock by touching the positive or negative terminals, I measured the AC leakage between the positive and negative terminals and Protective Earth with a Fluke 117C and a UNI-T UT139C.

The measured AC leakage was 70V 27 µA.

According to AS/NZS 60335.1:2020, the maximum permissible touch current from accessible parts to earth for Class II appliances is 250 µA AC.

Conclusion#

The SkyRC MC5000 Battery Charger and Analyzer may have dethroned the MC3000 as the ultimate cylindrical battery charger! What are your thoughts?

I am a massive fan of the physical clicky buttons. They are easy to use and fast. The scroll wheel feels so nice.

The 320x240 colour display provides access to plenty of details. The graphs look pretty cool.

The positive and negative terminals for each slot worked with all of my cells. It would be even better if the slots were 3mm longer so that 26800 cells fit comfortably (they fit but it was a squeeze).

SkyRC have been releasing multiple firmware updates for the MC5000 and they have been updating the SkyCharger app too. I appreciate how SkyRC have been accepting user feedback and how they have been making improvements available via firmware updates.

I would love to see a feature added where a user can save a particular Battery Type and Task to a list of Favourites and then quickly select and apply one of their favourite configurations to one or more slots.

The SkyRC MC5000 is one of the best battery chargers and analysers that I have tested. I can highly recommend it.

Pros:#

  • Great build quality.
  • Good user interface.
  • Good positive terminal design.
  • 320x240 colour display.
  • Physical buttons and scroll wheel instead of capacitive touch sensors.
  • 5A charging.
  • 2A discharging.
  • Fans and vents for cooling.
  • Beep (alarm) that can be adjusted or turned off.
  • USB-C PD3.0 65W output.
  • SkyCharger app for Android and iOS.

Cons:#

  • No favourites feature to save and recall commonly used tasks.
  • No USB-C input.
  • Unable to charge a protected cell when low voltage protection has been triggered.
  • -ΔV is limited to 3mV to 12mV. 0mV would be nice for some situations.
  • Discharge cut-off voltage is currently limited to 2.90V for Li-ion and LiFe.
  • Slightly too short to comfortably fit 26800 cells.
