3600 25C
1C = 3.6A
20C = 3.6A * 25 = 90A

3200 20C
1C = 3.2A
20C = 3.2A * 20 = 64A

4800 15C
1C = 4.8A
20C = 4.8A * 15 = 72A

If this is wrong, please let me know.
Im not an expert but my understanding is the C rating doesnt determine the power that is delivered but the power that can be pulled. If a motor wasnt stressing the 3200 at 22C then it wont be any better with a 3600 at 25C. Again Im no expert but thats my understanding from what other "experts" have posted.

"Any better" can be tricky, but I would go out on a limb and say that it wouldn't be noticable to a mere mortal.

Some guys on here seem to think they have senses so dialed that they can hear a mosquito fart in the next state...but for a stock motor that only draws maybe 25-30% of the capacity of a 3200 in 5 minutes...it really isn't going to make a substantial difference.

For the guys who can "feel" the difference between deans and direct soldering...you better run out and get them ASAP.

The 25c relates to maximum amp draw. I assume that the maximum amp draw is determined based on voltage drop and/or overheating potential. The heat developed is an inverse indicator of internal resistance (which is inversely related to punch). Lower internal resistance = greater amp delivery = more punch. Same thing with lower voltage drop, lower drop = higher Volts to motor = greater speed and greater acceleration under load.

In this case, bigger is better, right ?

But I thought you were the EE /computer guy, shouldn't you should be the one explaining these things ?

Just computers. I could program their website but I couldnt develop their batteries.

In context, though...if the system only flows 10 amps,it only flows 10 amps...it doesn't matter if the battery can flow 90. It may be slightly (SLIGHTLY) better after some time, but if it's a high resistance load, the "maximum" capacity of the battery really doesn't matter much.

Don't you remember? We are Orion fanboys by default since we questioned others' batteries. I think you need to pucker up and kiss Orion's ass like everyone expects. Shouldn't this release be applauded and bought up without question like when Apple went from ipod V1.0 to V1.0000000000001?

Oh that's right! How dare I ask questions I am a fan of my Orion 3200's and Im sure I will continue to be for a while until there is something different that can justify me switching (like a heavy lipo or one that noticably performs better).

correction....the 3200 is only 20C

Sorry, someone else posted 22. I thought 20 as well.

Which would be better for stock racing, with a 27 turn motor the 3200 thast already out or the 3600?

Probably either would be fine but I would go with the newest if you are buying new, so the 3600.

Any idea how much it will cost? Im would guess between he 3200 adn the 4800 but im probally wrong. Why is the 3600 bigger and will it fit in a hara cycloen without mods?

I'm curious how much the C rating matters when you're only loading the battery at 5C or 10C or whatever. What I mean, is, does it matter more to mod racers than stock, since they put the batteries under more load? Or, does a higher C rating mean the batteries will hold more voltage under all loads, including the smaller ones. It's not clear to what extent, if any, it really means to the layman that's just running them with slow motors in club races.

I've heard it said before that C is mostly a marketing term, and is way too ambiguous (especially between different manufacturers) to really mean anything. I wish we had a way to test LiPo that could really tell the story about how the cells will react on the track in different styles of racing. I'm not convinced the standard 35A discharge like we use with NiMH is the best way.
