Hello,
I would like to gather some real world users opinions of the Sanyo HR-SC2600 cells versus Gold Point 3300 versus Sanyo 2400 SCR cells. If you have compared any two or all three of these side-by-side in your application please respond with your thoughts on the performance of each. Also please include your application/setup and any current draw numbers you may know.

I'm very confused by what has been posted in various forums about each of these batteries and which is better for this and that. Some say the HR-SC2600 delivers just as much useable energy as the GP3300. Some say that the 2400 SCR cells are still better in terms of "punch". Please help by posting your experiences.

Thank you,
John

Nothing conflicting in anything you said. Why the confusion?

The HRSC2600 delivers just as much usable energy as the GP3300 because it releases what energy it has more efficiently. There is less loss through heat.

The CP2400SCR is a NiCd with very low internal resistance. It releases its energy slightly more efficiently than either of the previously mentioned cells. It has more "punch" in that it can maintain a higher level of current, more Amps, than the other two cells here.

For the casual sport flier, it's not going to matter much. All these comparisons were made at extreme current levels. Unless you're thinking of getting into competition, the cells will all perform similarly. The NiMH cells will have a bit more duration because of their increased capacity.

Matt,
Thank you for your reply. Why confusion you ask... Because different people are saying very different things about these cells, especially HR-SC2600 versus GP3300. The key, I agree, is the application and use of the cells; thus my reason for asking folks to post their setup when they respond.

I guess the real question is, "At what current level do HR-SC2600 cells outperform GP3300 cells in terms of total energy delivery and output voltage?" Based on the measured data I was able to find on these two cells, the GP3300 still considerably outperforms the HR-SC2600 at 30 Amps in both energy delivery and output voltage.

What about number of cycles? Someone responded to my post on another forum saying that the GP3300 only seems to last about 150 cycles. Anyone else have insight on that part of the equation?

When I called to order a 14-cell pack from a custom battery pack builder I originally asked for the HR-SC cells. But after talking to them about my application they recommended the GP3300 as a better choice. They said that the feedback they are getting from heli fliers is very positive for the GP3300. Their testing shows the GP3300 delivering full capacity + at 30 amps. So, confused as to which one is right for me, yes?

Thanks,
John

I like the gp3300 because they are a little lighter than the scr2400s and wene you add upyour 14 cells it will matter.+more run time and as you were told by your supplier 30 amps is no problem and you willnot need more than 30 amps at 14 cell count(14 cells x1.2 volts=16.8voltsx30 amps=WOW dats o lot o WATTS!!

Well, that is 504 Watts. My Logo 10 weighs 5 lbs 9 oz so that would be about 90 W/lb. Not a lot of power if that was the max it draws. But actually the short term current draws and power output will be much higher than that.

Anyways, I'll see how my new GP3300 pack does when it comes in.

Thanks,
John
