MaxAmps Voltage Drop Graph

[TexasSP]

I have heard several people swear by the truerc packs, I guess it wasn't BS after all. Thanks for the graphs, that was good to see yet disappointing and great at the same time. All in all it makes me glad I am selling the last of my maxamps packs off.

So is this a chart of 10 full pack cycles, plotted to a line for each pack? We are seeing the average voltage over the discharge of the pack, or some other finite time period?


Good info, I like to see data like this.

It's the average voltage for every point that the pack hit a specific range of current.

It was nowhere near that scientific. I noticed that the Li-Saver LVC kept tripping on my Revo even when the packs were fresh off the charger. It did it with any combination of my four 2s 6k MaxAmps packs. I thought it was a problem with the LVC, until someone on here suggested that I test the packs to see if they were just dropping voltage that badly under load.

I tested each pack seperately in my Kyosho buggy for about 10 minutes each. Each pack was fresh off the charger when the test run began. I used the first 1000 mAh of each test for the graph. I tried my best to run the car the same for each test on the same "track" in front of my house. I basically did laps through my lawn and my neighbor's lawn across the street, stopping hard at the end of each lap and starting hard again at the beginning of each lap.

If I were trying for a lawsuit or something, I'm sure better tests could be performed. The only real test I need is the fact that I can't run these packs in my Revo without tripping the LVC on take-off.

Now I know, at least for myself, not to spend any more of my money on MA packs. I also had two 3s 5k packs of theirs puff a cell within the first 10 or so cycles each. I guess I can't sell these packs, so I'll just keep them around for smaller lighter vehicles. Maybe I'll run them in parallel if I can fit them in a different application.

I wish I had the time to do better testing, but this small test was proof enough for me.
