The way they come up with % numbers is by measuring the voltage. They then pull the % out of a lookup table. The problem is that the voltage will be different with the applied load and how long after the load was removed. This is why flying to a set voltage is not as good as flying for a set time period. Anyway - A 30 minute discharge is 2C. Way too fast to accurately hit 3.73V. The way I do it is load the pack till the voltage hits about 3.80V , then lower the load to 1/10C till it hits 3.73V average ( across 6 cells). I use a watt meter for this. Very useful tool. |

Well I finally got through the break in stage of these packs. Decided to use them as the tests came back very close to the rated mah's.
The only flight that I think is worth reporting on was just hovering and forward flight. Fusion 50 5 Min. @ 2000 rpms. (tached it so I am sure) Put 1203 mah's on one set and 1217 mah's on the other. Weird that they were so close. All cells were 3.94-3.96V My last break in flight with each was more or less the same flight style but on the last 1:30 min. I used Idle 2, 2200 rpm, flying tic tocs pitch pumps and light piroing stuff. Still waiting to charge them to see where they are at. I will report back after I really start to fly these @2300 +/- rpm's.
