RE: E-FLIGHT BLADE CP

There's only a .2V difference between those batteries. Not enough to make a difference. Basically it might run longer, but it will provide about the same amount of raw power. If you want more raw power, you have to up the voltage.
With NiMH batteries the drop off is sharp....it's running fine, then blam....its dead.
With the aerobatic kit, the heli needs more voltage. Anyone that has flown the aerobatic upgrades on the stock battery will tell you the heli will barely get airborne. That low voltage just doesnt have the umph it needs to spin the symmetrical blades fast enough to produce enough lift to counteract the heli's weight.
Motors are electrically stupid. They will pull as much as you can give them to the point where they will literally kill themselves by overfeeding on the juice. Take a stock tail motor....shove it on a 11.1V battery all by itself. It will try to devour everything the battery can give it till it runs so fast and hard that it burns itself out. Dumb motor. They will also try to pull what they need to accomplish their task, if it needs 11.1V its gonna try to get it, if it cant get it, it uses what it can with the degraded performance.
With the 11.1V 1250mah lipo, at full charge it will hold close to 12.40V. At about 25min into flight my lipo hits about 11.26V and I start losing available power, at 28min the lipo reaches 11.16V and its coming down...whether I like it or not, but it still has enough power to do a nice gentle landing and have full control. If you try going below 11.16V it will barely get airborne, and stability decreases alot. The gyro will start doing funny things and you will lose some tail stability.
Lipos have many different ratings. 11.1 V 1250mah = 11.1V 1.25A battery. Meaning you can charge it at 1250mah or 1.25A per hour max. mah = milliamps per hour. They also have a discharge rating. Most high quality lipos have around 10A normal discharge rate, with a 16A burst rate. This means that the battery is able to allow something to suck 10A continous from the battery without heat buildup, and 16A for short periods of time.
