| Hello,
I know I made a post on another thread recommending the HR-SC2600 over the GP3300 for the Logo. But then I got to thinking that I don't know exactly how many cycles are on each of my packs so that could be a factor in that recommendation.
OK, here we go... I've read on this and other forums that the HR-SC2600 delivers just as much useable energy as the GP3300. However, looking at discharge curves would seem to indicate otherwise at least up to the 20 A level which is the highest common discharge current charts I could find. For example, the GP3300 drops below the 1.2 V mark at 260 seconds and hits the 1.1 V mark at 580 seconds. The HR-SC2600, on the other hand drops below 1.2 V at 150 seconds and drops below 1.1 V at 390 seconds. That is a big difference!
Further, making me more confused is that I called to order a custom battery pack yesterday with the intent of getting the HR-SC2600s but after talking with them about my application they recommended the GP3300 as a better choice. They added that they are getting very favorable feedback on the GP3300 from heli pilots.
I've also read that the GP3300 doesn't last as many cycles, maybe only 150 usefull cycles.
I have the distinct feeling that there is a crossover point with respect to current where the performance of the HR-SC2600 and the GP3300 meet. But, what is that current level?
I throw in the 2400 SCR because some are saying it simply has more "punch" these other two.
So, could anyone with quantitative data post their experience with one or more of the cell types? I'm looking setup and numbers such as usefull flight time and current draw if known.
Thanks,
John |
