First impression of the B6AC V2

The box of the B6AC V2 is full of information and already makes fun of unpacking. Included with were in addition to the charger still all kinds of things Connection cable with crocodile clips, XT60, Futaba and JST sockets, On Adapter cable with banana plug was included as well. Of course, there was also one power cable and English manual at.

SkyRC Imax B6AC V2 Balancer Charger Review

The processing of the charger is good. The housing is completely made aluminium and is labeled in great detail. Where there is something and what the device ultimately can is already printed on the housing. The integrated LCD Display has a backlight and is easy to read.

On the left side of the case are one AC input (240V 50 / 60 Hz), DC input (11-18V) one micro USB socket, via which the B6AC V2 can be connected to the PC and a connection possibility for one Temperature sensor, which is not included in the delivery. Also not included is the WiFi module, so that the charger can also be operated with a suitable app.

On the right side of the case are the Balance sockets (up to 6 cells) and the charging output, On the back was synonymous with the version 2 the SkyRC Certificate of Authenticity attached, which can be scratched below. With the number rubbed off, the authenticity of the device can then be checked on the website of the manufacturer. One should carry out this review also in any case, since the predecessor model already numerous counterfeits are in circulation. However, fakes of the 2 version are not known at the moment.

Commissioning and functions

The SkyRC charger can be powered via the AC or DC input. Thus, for example, the SkyRC B6AC V2 can be operated directly with a 11-18V battery, which was previously possibly used in its quadrocopter.

On the basis of my Cheerson CX-20 LiPo with 11.1V and 2.7A I would like to describe the charging process in more detail. Before you connect the charger to the power, the battery should already be connected. To do this, connect the balancer cable to the Balance Socket and connect the charging cable to the XT60 connector of the LiPo via the matching adapter cable. In any case, you should first connect the adapter cable to the charger and only then connect the battery. Otherwise there is a risk of a short circuit.

If the battery is switched on and the charger is connected to a power source, we can select or adapt our desired configuration via the display and the menu buttons. You can load the B6AC V2 LiPo / LiFe / LiIon batteries with 1-6 cells, NiMH / NiCd batteries with 1-15 cells and lead-acid batteries with 2-20V, Is loaded with 0.1-6.0Aunload with 0.1-2.0A.

Before we choose our suitable battery type, we can in the System Settings make various settings. Among other things, you can set here: a Safety Timer, a Capacity Cut-Off, a Temp Cut-Off, the temperature unit, the idle time, the NiMH / NiCd Sensitivity, the sounds and an Input Power Low Cut-Off. In addition, you can view the firmware and hardware version, as well as the serial number.

In addition to the charging function, there is also one Charging Indicator, on which you can see the volts of the individual cells, it can be a resistivity the battery can be done and you can individual loading profiles invest.

Once you have selected the right battery type in the start menu, in my case "LiPo", you can then choose between different modes.

Balance charge

In this mode, the voltage of each cell is adjusted during charging.

Charge

The charger charges the individual cells to the specified voltage and then keeps them at the constant voltage.

Fast Charge

In this mode, the cells are only charged up to set voltage. The constant voltage is not kept, which is why the battery is usually only charged by 80%.

storage

The cells of the battery are charged / discharged to the best possible voltage for storage.

Discharge

Discharge the cells

For the other types of batteries there are correspondingly adapted modes. For the NiMH and NiCd batteries these are Charge, Auto Charge, Discharge, Re-Peak and Cycle. For Lead-acid batteries there are the modes Charge and Discharge.

The individual LiPo modes I've tried with the stick Cheerson CX-20 LiPo. Balance mode works as expected and is accurate. For independent verification you can use a LiPo-Checker or measure with a multimeter on the balancer connector. The storage mode works exactly as well and the B6AC also manages the unloading and recharging as desired.

Software

If you would like to operate the SkyRC IMAX B6AC V2 on the PC, the manufacturer will provide the so-called "Charger Master" Software ready. Using a graphical user interface, the B6AC V2 can be configured as desired. The configuration options are the same, which can also be selected directly via the device. Firmware updates can also be uploaded to the B6AC V2 via the software.

So when I read something: "Here you should definitely first connect the adapter cable with the battery and only then insert the banana plug into the charging socket. Otherwise there is a risk of a short circuit. "I get goose bumps !! This can not be!??? Or how did that mean? Can that happen so easily?

Hi Andreas, thanks for the hint. This is of course wrong formulated and I will correct the mistake quickly! I actually meant you should first connect the adapter cable to the charger, then connect the battery and only at the end turn on the charger. If you first connect the battery with the adapter cable, it can quickly happen that the two banana plugs touch and it comes to a short.

Yes, that can happen. Of course it is good to know that such texts are also read well and lead to corrections.
