Default Discharge curve monitor

Is there any inexpensive way to log discharge curves? maybe a simple pc program that can read the voltage via a serial port while a pack on like a indi 30?

If you create a login at gearchart.com you can upload the results from a gfx and have a nice little formatted table of the discharge curve information.

Anything else? I don't want to buy a GFX at the moment.
I had seen a post a while ago where someone had modified their DPD and were logging it on the pc, I have a dpd, but it doesn't give a graph only average voltage.

As promised, you can make your own discharge curve with just a volt-o-meter. Consult the May 2005 issue of RC Driver. Gary Katzer did a great write up on how to plot and graph the discharge curve of your batteries. I donít know if the article is on line, but you can contact RC Driver and I am sure they will help you out.

I recommend you this product. This product is premised on using it, carrying in chassis. However, this will operate, even if it connects between charger and battery. Temperature can also be measured if the Optional sensor is purchased.

I use a basic voltmeter that has an RS-232 connection for a PC. Hook up whatever your discharger of choice is and then clip the voltmeter on as well and record the voltage as the discharger runs. Works like a charm.

That is nice, not exactly inexpensive, but looks to be well worth the money Nice Find
