My Thunder AC6 Charger came in today and I've been playing with it a little bit. So far I've charged 3 NimH packs and on my 2nd Lipo pack. Both of the LiPo packs were already charged so I tested on them by selecting discharge or storage mode to run them down a little, then charged them back up. I put the software and driver CD in my laptop, installed the software, plugged the charger into the USB port, loaded the drivers, and it all worked.
On the NimH packs, I charged 2ea 4 Cell Rx packs at 1.6A and then I charged a 6 Cell car pack at 4A. On the default sensitivity, the charge terminated at around 0.05V below the peak. The charger never got warm charging these packs.
The LiPo's I tried were 3 cell 1050 packs that I already had charged. I discharged them a little bit and then charged to check the balance and final voltage. The charger showed 4.20V per cell and my Radio Shack Voltmeter showed 12.69V total and 4.23V per cell. That's within 1% but I'd like to find out if the error is in the meter or the charger. Some cheapy chargers similar to this have an adjustment where you hold a button down while you power up and it will let you adjust the voltage readings to your meter.
The software that comes with it is pretty basic, but it has more than I expected. You can choolse the graph you want to look at, Volt & Current, Volt & Temperature, Volt & Capacity, or voltage for each individual cell. The software also shows the settings for battery type, mode, temperature cutoff, mah cutoff, on time, and input volts. The sofware has a cursor that you can position anywhere along the plot and it will give you the digital readout for that position on the graph.
So far this charger seems great, now if it just continues to perform well I'll be satisfied. AC or DC Input, 0.1-5A charge, 0.1 to 1A discharge, USB cable, Software, comes with 5 charge cables and a temperature cable, plus USB cable and balance adapter board. For $55 and $4.95 shipping I'm quite happy with it so far.
