Nice little lipo - 09.18.2007, 12:52 PM

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.
