Test/review of Charger GyrFalcon All-88 2017 (Enova)

GyrFalcon All-88 2017 (Enova)

Enova has updated their universal 8 slot charger.

DSC_2511 DSC_2513

DSC_2512
DSC_2514

The cardboard box lists a lot of specifications for the charger.

DSC_2535

The box included the charger, a power supply, some accessories for special battery sizes and a instruction sheet.

DSC_2536

The accessories are spacers for handling small batteries and some extensions for the plus connection for handling C, D and 32xxxx size batteries

DSC_3550DSC_3551

The extension in use.

DSC_2543

The DC input is the usual barrel connector and it is rated for 12V input at 4A.

DSC_3542

The display has many elements on it, because the charger can handle many types of cells.

DSC_3540

One this image the charger is in automatic mode, i.e. it is not possible to select voltage, that will be done automatic and only NiMH and 4.2V LiIon can be charged. (Hold down Fn and CV for some time to switch between manual and automatic)

In manual mode it is possible to select both voltage and current for each slot:
Press button for slot to select it.
Press button for slot again to select voltage.
Press CV to select current setting.
Press button for slot to select current.
Press CV to select voltage setting again.
Hold button for slot down to start charging.

Start a slot (Method 2):
Press button for slot to select it.
Press button for slot again to select voltage.
Hold button for slot down to start charging.
Press CV to select current setting.
Press button for slot to select current.

The above methods are rather long if you want to charge many cells, the charger has some shortcuts to handle that:
Hold button for charging slot down and tap button for other channel will copy the settings and start charging on the other channel.
Hold Fn down and press CV will select 1A and 4.2V charge voltage for all idle slots, pressing multiple times on CV will change voltage.

These short-cuts means that charging any number of (4.2V) 18650, 26650, 32650 can be started by holding Fn down and tapping once on CV.
Charging any number of AA can be starting by holding Fn down and tapping CV twice.

DSC_3543

The C.A line shows selected current and is also used to select current when the “>>” marking is at this line.
The V.V line shows selected charge voltage and is also used to the select voltage when the “>>” marker is flashing at this line.
The battery icon is animated when the charger is charging.
The display will automatic dim after some time, any button press will bring it back to full brightness.

DSC_3544

In this image adjustment of current is select (>> is at the C.A. line).

DSC_2545DSC_2546

The sliders work very smooth and can handle from 30.2mm to 71.7mm, up to ø26mm cells can be placed in each slot and it is possible to use ø32mm cells in each other slot when the extension is used (Only two supplied). For NiMH extension must be used for both C and D cell.
Due to the wide slots, care has to be taken with thinner batteries to get a connection.

DSC_3550DSC_3551

Using the “Extensions” both C and D cell can be charged.

DSC_3546DSC_3545

DSC_3548DSC_3549

DSC_3547

With 10180 cell the 100mA charge current is on the high side, but because most 10180 are high current cell it will usual be acceptable.
C, D & 32xxx cells can have trouble with the plus connection, using the small extender will fix this.



Measurements on charger


  • Power consumption when idle is 0.8 watt with display off (1.4 watt with display on).
  • Will discharge a LiIon with 0.1mA when not charging.
  • Will discharge a NiMH with 0.15mA when not charging.
  • Will not charge at 0 volt.
  • LiIon charging start at about 1.0 volt with a few mA.
  • NiMH charging start at 0.7 volt with selected current.
  • Ib automatic mode it will assume LiIon above 2V
  • From about 1.5 volt to 3.0 volt it will charge with 50mA (72mA for 0.5 and 1A charge current), this is the same for all LiIon chemistries.
  • Above 3.0 volt the select current will be used
  • Meter starts working at 0.7 volt, but is first precise at around 1 volt.
  • Meter is within 0.03 volt.
  • Meter stops updating when battery is full.
  • Meter will not reduce reading.
  • Charger will restart silent if LiIon battery voltage drops below 4.1 volt (4.2V charging).
  • Power cycling and insertion of a battery requires button press to start charging in manual mode.


Charging 4.20V LiIon cells

GyrFalcon%20All-88%201A%20%28SA18650-33%29%20%231

The charger uses a CC/CV charge curve with 100mA termination at 1A charge current.

GyrFalcon%20All-88%201A%20%28SA18650-33%29%20%238

All the other slots look the same, but there is a small variation in final voltage, it is within acceptable tolerances.

GyrFalcon%20All-88%201A%20%28SA18650-26%29%20%231
GyrFalcon%20All-88%201A%20%28PA18650-31%29%20%231
GyrFalcon%20All-88%201A%20%28BE18650-26%29%20%231

These cells are also handled nicely, even the old one.

GyrFalcon%20All-88%200.25A%20%28SA18650-33%29%20%231

A very low charge current also works and there is not timeout.

GyrFalcon%20All-88%200.5A%20%28AW18350-IMR%29%20%231

This very old cell drops significantly in voltage when charging stops and the charger restarts again. I could probably have avoided this by selecting a lower charge current.

GyrFalcon%20All-88%200.5A%20%28KP14500-08%29%20%231

The 14500 is not as worn and the charger stops as it is supposed to do.
It looks like the termination current at 0.5A charge is 100mA, this is a bit on the high side.

GyrFalcon%20All-88%201A%20%288xSA18650-33%29

The charger can handle 8 cells at 1A simultaneous.

GyrFalcon%20All-88%201A%2012V%20%288xSA18650-33%29

Charging 8 cells requires nearly 4A from 12V

Temp4735

M1: 44,4°C, M2: 46,3°C, M3: 49,0°C, M4: 48,4°C, M5: 49,5°C, M6: 46,1°C, M7: 46,2°C, M8: 41,0°C, M9: 48,6°C, HS1: 54,4°C
When charging 8 cells at full current some cells are fairly warm.

Temp4735

M1: 60,4°C, HS1: 69,9°C

PoweronLiIon

Here I tested in automatic mode, where the charger starts in about 2 seconds.

CurrentChangeLiIon

It is possible to change current during charge.



Charging 4.35V LiIon cells

GyrFalcon%20All-88%201A%20%28LG18650-30%29%20%231

The charger supports both 4.30V and 4.35V cells, I only did a test with 4.35V and it looks fine.



Charging 3.6V LiFePO4 cells

GyrFalcon%20All-88%201A%20%2818650-LiFePO4%29%20%231

GyrFalcon%20All-88%200.5A%20%28SO14500-LiFePO4%29%20%231

The charger charges LiFePO4 to 3.6V, but the restart voltage is too high, i.e. the charger will restart a couple of times after it is finished.




Charging NiMH cells

GyrFalcon%20All-88%201A%20%28eneloop%29%20%231

The NiMH charging stops on -dv/dt and looks fine.

GyrFalcon%20All-88%201A%20%28eneloop%29%20%232
GyrFalcon%20All-88%201A%20%28eneloop%29%20%233

GyrFalcon%20All-88%201A%20%28eneloop%29%20%238

On all slots, there is a small difference in current, but that is not important.

GyrFalcon%20All-88%201A%20%28eneloopPro%29%20%231
GyrFalcon%20All-88%201A%20%28powerex%29%20%231

The two high capacity cells are handled fine.

GyrFalcon%20All-88%200.25A%20%28eneloop%29%20%231

Here I use a very low charge current on a NiMH and the charger terminates fine.

GyrFalcon%20All-88%201A%20full%20%28eneloop%29%20%231

With -dv/dt termination it will take some time to detect a full cell, here it is about 13 minutes.

GyrFalcon%20All-88%200.5A%20%28eneloopAAA%29%20%231

No problems with a AAA cell at 0.5A

GyrFalcon%20All-88%201A%20%288xeneloop%29

No problem with charging 8 NiMH cells at a time.

GyrFalcon%20All-88%201A%2012V%20%288xeneloop%29

It needs a bit below 2A at 12V for charging 8 NiMH cells.

Temp4741

M1: 47,8°C, M2: 49,0°C, M3: 50,3°C, M4: 49,0°C, M5: 50,6°C, M6: 49,2°C, M7: 47,9°C, M8: 43,1°C, HS1: 55,3°C
8 cells at full current will give some heat.

PoweronNiMH

Starting is exactly the same as for LiIon.

CurrentChangeNiMH

Current change is also the same.

ChargingNiMH

With NiMH the charger stops every 20 seconds to check the voltage of the cells.


Testing with 2830 volt and 4242 volt between mains and low volt side, did not show any safety problems with the transformer.



Conclusion

This is a fairly advanced charger with support for most round cells on the market, both fairly large and very small. The automatic mode makes it very simple to use and the advanced mode adds support for just about any cell on the market. To use the advanced mode it is a good idea to learn the short cuts, this makes it fast to program multiple slots.

Due to the wide slots, it is necessary to be a bit careful when loading thinner cells (Like AA), they have to be centered in the slot.

I will rated this charger as a very good charger, but it requires a bit care when starting a charge.



Notes

The charger was supplied by Enova for review.

A grand review. But then again: it’s a big charger. Thank you Henrik.
If I did not already own chargers up the wazoo, I knew what to buy when waiting for my BLF GT!

But if you have “only a few” chargers, and live in/around the US, check out RMM ‘s store.

I always think long and hard before I say something really stupid.

Thansk HKJ. I’ve been using the old version of this charger for over 12 months now and very happy with it.

My current and or voltage measurements are only relevent to anything that I measure.

Thanks for the review HKJ.

I got this charger some few weeks back and I really like it.
(But it is not just plug an play, you need to check what you are doing. Just use it a few times and there is no problem.)
I did not get the spacers, but I got four of the extensions plugs for the plus connection.

Some of my experiences with this charger:
- Charger will remember the state of each slot, you don’t need to re-setting each slot if you want to charge a same type of battery at a same slot, just put battery in and press and hold slot button for 3 seconds.
- If power is recycled, memories will lost.

Thorough review as usual, HKJ.
I have been using the previous version of this charger and it has become my favorite, due to it’s versatility.
Also love the capacity!
