The GT Power A606-D comes with a variety of charging leads with different connectors like Deans, BEC, JST, glow starter and alligator clips. If you already have your leads, no problem, the charger accepts banana style connectors. A USB cable and software is also included to monitor your battery packs while you charge them. It quickly shows the current voltage, peak and many detailed information that we usually have to search through the charger’s display. You can also, set up the charger through the software. However, I didn’t try this function, I’m an “old school” and I prefer push buttons to navigate in the charger’s menus to find what I’m looking for. The menus are easy to understand and to navigate through them. Few clicks here and then and the charger was correctly configured. The LCD display is back lighted and clear, so reading the display will not be a problem even outside on sunny days.
The charger is made of a robust metal case. To keep the charger cool, there are two heatsinks at the top and bottom and a silent cooling fan is integrated to the charger. Four big buttons are used to program and configure the charger. On the charger’s left side, there are the AC (100v-240v) and DC (11v-18v) power inputs, a USB and temperature sensor connectors. On the right side you can find the power output banana connectors and five different JST-XH connectors to balance your LiPo/LiFe/LiLo packs. The GT Power A606-D is not just a charger, it is also a discharger and a cycler to revive any kind of battery packs.

The first test I did with the charger was to charge two types of NiMh packs. One 6v (1500 mAh) receiver pack and a 7.2v (4200mAh) NiMh pack. Only few clicks were required to configure the charger according to my packs specifications. I first charged the receiver pack at 1.0A rate. The receiver pack wasn’t been used for many weeks and it was very low. About an hour later, the charger beeped and my receiver pack was fully charged and slightly warm. The next pack was a 7.2v pack. Once again, few clicks to set up the charging amperage at 4.2A and after having holding the start button few seconds, the charger began to charge my pack. As expected, the charger beeped 50 minutes later with a pack completely charged.
Gel cell charging:
If you run nitro, there are good chances that you are using a gel cell for your starter box. To test the GT Power A606-D, I’ve connected the alligator clips to my 12v gel battery. I knew my starter box’s cell was low because I haven’t used it since a long time. After I had set up the charger for 12v Pb cells and set the amp rate to 5A, the charger ran for more than 75 minutes before it beeps and my 12v gel cell was fully charged and ready to power up my starter box.
LiPo packs are the type of packs where the GT Power A606-D really shines. To test the charger, I’ve charged one of my favorite 2S (5000 mAh) LiPo packs. I know how this battery pack reacts to charging, so I was able to compare how the GT Power A606-D works versus the charger I usually use for my charging needs. After I had connected my LiPo pack to the output leads and balancer, I set the charger for a 2S LiPo battery and hold the Start button for few seconds the charger beeped and started to detect what configuration of LiPo battery was connected and then asked me to validate the settings. This is a very nice feature to prevent overcharging LiPo batteries. To validate, simply click on the Start button. Like for all others types of batteries, the charger displays the time, the charging amp, the voltage and the capacity. For LiPo batteries, press one of the yellow button and the charger will display the voltage for each cells. The charger has fully and safely charged and balanced my LiPo pack and of course, the pack was not hot and each cells showed precisely 4.20v at the end of the charging process.
With today’s high performance battery packs, you need a high performance charger that can handle any batteries of any types and capacities. The G.T. Power A606-D is one of the best chargers in this category. It can charge, discharge and cycle any type of batteries. It is robust, easy to operate, fan cooled and it has a clear back-lighted display. It can easily compete and win against any other similar and more expensive chargers on the market.
The GT Power A606-D charger and all others GT Power chargers are fully warranty one year.
Here is a small update about the charger…
I use this charger since many months now. I only have good words about the G.T. Power A606-D Charger. I have charged any kind of battery packs with it. From NiCD to LiPo, the charger always did it right with no false peak. It always operated extremely well. It is easy to operate and extremely accurate.
No matter what RC products I review, there is always a big or small negative point but in the case of the G.T. Power A606-D Charger, I only have good words for it. It is the perfect charger. I’m amazed and it is my number one charger no matter what pack I charge.
