Home-brew battery measuring station

LOL

I posted data a couple years ago on my maxamps packs... showing much better numbers than what was being talked about here. The reaction was that I must have something wrong with my eagletree or something because they wanted to believe the crappy numbers someone else got with their packs.

Trust me... if MA packs get good #'s then people here will take issue with it, and continue to march with their pitchforks and torches.

I have never, and still don't... make exaggerated claims about maxamps packs. When I posted data in the past, it showed they were not even the best packs I had at the time. My 20c kokam had the best #'s. I've also posted in the past that my Core 5000 pack had better #'s than a similar MA pack in the same test.

I do remember seeing your numbers. From what I can remember they were similar to the results I had with my maxamps packs.

Performance was not really my issue with the dozen or so packs I had. It was longevity. I had them puff just sitting, and had to weed out the bad cells to make good packs. Once I had done that the packs were decent, and I even sold them. Some are still running today, so my "backyard matching process" (trial by fire so to speak) apparently worked.

The packs I had, 3000, 4000, 5000 and 10000 cells, just did not have enough headroom to handle the setups I had going at the time. To be fair I was trying to push a MT on a 4s setup, and we all know that 4s in a heavy vehicle is hard on lipos. The fact that my trakpower packs outperformed the ma 5k packs and were cheaper kinda sealed the deal for me. Then there was the Jason incident, and that opened my eyes to the fact that money overcomes truth for some people...

Please post a link to your numbers GD, I would like to see them again, now that I have a better appreciation for lipos.
