I have a stock dolphin I have a 7.4v 1200mah li-ion battery how much flight time should I get? Should I use another battery? Would it damage the motor to go to 11.1v li po?

It pretty much wont work with that 7.4v 1200mah battery, you will need a 11.1, and greater capacity than 1200, 1320 TP would be mininum I think.

I would recommend a Apogee 1570, I got one of those and I am very happy with it. 3000mah is too big.

I use 1570 to 2200mah and I get around 10 to 12 minutes of flight.

depending on what type of flight you are making, you can pick the capacity.
I use 3-cell(11.1v) Thunder Power 1320mah. To me this is a perfect match if you are not looking for longer flight times. If you are into 3D then I guess this is the best buy. It smaller, lighter and , cheaper than Apogee 1570. The only advantage Apogee has(it is really not an advantage because it has more capacity) over TP 1320 is that it gives you 2 more minutes of flight time which shouldn't be a big deal.
I tried that pack on my friend's Shogun and really wasn't impressed at all. You will need a battery extention tray to fit that Apogee in your Shogun, Or you will need to cut the frame a little bit where Thunder Power TP1320 will fit right in w/o any modification.

To me it is a great battery.

In short, you will need 3-cell lipo and you will decide on the capacity. You can go for TP 2100 but you definitley don't need more than that.

Hope this helps

I get a greater advantage than 2 minutes, also I get more power with the apogee than the thunder power. So to me the wieght savings on the TP does not matter since I get more power with the Apogee so it will 3d better, I m not saying the TP is bad, I have one of those as well.

If the discharge rates are same, all 3-cell lipo packs should give pretty much the same power.
TP 1320 (G2) and Apogee 1570 have very similar discharge rate. I believe around 10C (or maybe more)
So there is no reason why 3-cell Apogee should perform better than 3-cell TP. If you have had the TP for a while and just got the Apogee, you may think that it works better since newer packs will have less cycle and run time.
So if one gets brandnew TP and Apogee, there should be no difference as for the performance.

No thats wrong, the discharge rate is based upon the capacity, if its 10c then a 1320 will give 13.2a continious, and a 1570 will give 15.7amps continious. The apogee 1570 is rated at 16.5amps continious about 10.5c, the Thunder Power is rated at 10.5c as well I think, and thats about 14.5a continous, so the Apogee will give more power, and to me Numbers don't mean everything, I usually go by how it flies, and I can feel a difference between the two packs. And no my TP doesn't have very much time on it at all, maybe 10cycles, my Apogee now has only a few cycles on it. The TP battery shouldn't be degrated at all yet.

That's ok. I used both packs and didn't see much difference. But if you say your Apogee works better than TP, I undestrand that. It just didn't work the same way when I tried them.

Shogun Battery
I think 1320 from t.p. is a good choice it has a very good punch for 3d and weight about 90 grams I also use 1550 from tanic and it has more power but weight 119 grams.I use E-Flight 400 9 t. pinion MAH C.F.Blades and fly 10 min. of 3D.

Hi All,

I'm using both the TP1320 and Apogee 1570. The 1570 are newer by a couple months. I'm pleased with both. The 1570's give me aroun 19-20 minutes of flight time where I'm getting 14-16 on the 1320's. This is with no 3D, just hoving, circles, etc.

I do prefer the form factor of the tp1320's it's a better fit on my bird. I moved a few components around to accomodate the Apogee's and both now fit fine with a good CG.

The Apogees are thinner but wider. This makes getting the canopy on a bit of a squeeze but it works.

Either will suit you for a long time.

Cheers,
Leslie

It really is not the factor what setup I am running. Because tried the both packs on my heli(with the same setup) and saw no significant difference other than flight time.
My friend had his Apogee and he wasn't getting a good performance. So he asked me to test his pack. I put it on my Shogun and flew it. It performed better on my heli than it did on his. So we determined that the problem he was having was not due to the battery pack. But both packs (TP 1320 and Apogee 1570) performed pretty mcuh the same way on my Shogun.
I am not saying that Apogee is not a good battery, I just like TP better due to the several reason I stated above. It fits better, it is lighter and also cheaper.

I agree with Wedge.

I have a 3s 1800mah Lipo and a 3s 2200mah
and the 2200 has MORE power you can feel it and see it. and hear it.

The TP1320, are about the worst cell for the Shogun, I have a TP 1320 Gen2 and it isn't anywhere near the Apogee 1570, not even close.

When I nail full collective the TP1320 chokes, When I nail it with the Apogee I get full collective.

I used to like TP untill I tried Apogee.

Capacity is the indication of how long the battery will be delivering its power. It is in NO way the indication of the max power you can get.
The more capacity you have the longer your battery will last under the same conditions. 2000mah battery will deliver the power twice as long as the 1000mah battery of SAME kind.
This is the physics. I am not going to argue this.

I like TP cells for my Shogun, if you like Apogee then you buy Apogee.
