Nice little lipo
 

Here is the scenario. I'm testing 2 11.1V 2200mAh packs that I'm thinking of bringing them to the US. I've made 2 runs with them and the numbers are looking good so far. I used my Ofna MBX with the BK 3695, Hacker C50-13L to test this little packs. I know for sure they can put out 128A burst. On graph A I only ran the buggy for around 15 minutes. Now the second run was done today and I ran until I noticed the speed decreasing, but I just went a tad more to around 24 minutes to see what the packs would do. They did swell up just a bit which has occurred to other bigger capacities packs I have, but it is expected for them to expand a little as the datasheet of most lipos shows a +- on the dimensions. Now this are 2200mAh, but on the second run it shows that I took out 3658mAh and the minimum voltage was 7.14V. I've had my share of lipos and most went bad and some went dead. I know most of you think the packs are dead, but they are not. I waited until they were cool and put one pack on my AF109 and it showed 9.58V. After the pack is done charging I will post how many mAh it took in.

The pack took in 2090mAh. I will charge the other pack later today to see what it takes in.

I just put the other pack in the charger and it showed 9.88V. I will post again after it is done charging to see how many mAh it took in.

that is some incredible batteries. I got a plane shop here testing some that they claim you don't need a LVC and they don't heat up or swell, Just run till you see a difference then change. He has doubled his flight times, just swapping to these batteries. didn't have a wrapper to identify them though

It could either be KongPower or Airthunder. This packs I have are made from the same OEM that provides the batteries to those companies.

Took the other pack of the charger and it took in 2051mAh. I will run the MaxAmps 11.1V 4000mAh packs I have just for a little comparison.

Let me get this straight, you burned 3600 mah and took 2000 in? That sounds like getting something for nothing, thats almost impossible. Good find, i might have to try some

I actually pushed them a lot more than I would have with other packs. I thought that was strange, but it might be a misreading on the DPR-II-150. The first few graphs everything seems to line up right, but now as you can see the Max 128A doesn't line up with the graph. I tried downloading the newest firmware again to see if it helped, but it didn't.

I ran the MaxAmps 11.1V 4000mAh packs yesterday and it didn't perform like the smaller 11.1V 2200mAh packs did. I had to stop at around 8 minutes due to the packs heat and a swelling issue that was uncomfortable to see. The swelling has gone down and they charged ok, but I'll just run them on my Stampede from now on LOL. I will run the KongPower 11.1V 2200mAh today and see the results they give me.

were you running th 2200 packs in parallel? Thats the only way I could see these things putting out that kind of amp and run time. On a 2200mah pack 128Amps would be 58C and the total discharge of 3600+ mah makes no sense.

These must be paralle numbers. which bring the peak discharges down to a more reasonable 29C

I was running them in series. The voltage was at a little over 25V. I was going to compare them with the KongPower 11.1V 2200mAh packs also in series, but I forgot to turn off my rx pack and I drained it, but I'll run it tomorrow.

Some pictures of the set up.

Some more.

erh; i see a 15V dip on a 112A load. for a 6S pack that is hitting bottom (and beyond) 18V should be the CV, at 50A (rather fresh charged) they hit their limit. (18V) 50A is roughly 22C. Good to see they hold up though, but tourturing them like this will shorten their lifespan for sure!

You should def. use them in 2P in your application.

I'm doing this torture test to see if the claims are correct. This have the same ratings as the KongPower and Airthunder packs. They are supposed to be true 25C continuous discharge with 50C+- bursts. I will run the KongPower 11.1V 2200mAh packs in a few minutes and I'll post the graph of that run.
