1)I have an R/C plane with a battery pack that is 9.6V250mAIm looking for backup battery packs, my question is, is this an okay battery to buy it looks the same but I know little about electronics2)If it sounds like i can buy the other battery, what voltage/mA can i go up too, Because I want the longest flight time /capacity
With electronics, they're typically built for a specific voltage. Always stick with the same voltage rating. The mA-hr rating refers to how long the battery will last. It's the product of the current (how much power the battery is providing) and the total time at that current. For example, a 250 mAh battery will last for one hour when providing 250 mA. It will last 0.5 hrs when providing 500 mA. The bigger the number, the longer it will last.
1.) I believe that you got the units wrong. mA is a unit of current, mAh is a unit of energy. Don't get the two confused. 2.) If you want to increase the duration of your plane, then what you need is a battery with a higher mAh capacity. mAh dictates the amount of energy the battery has. Thus the more energy the battery has(measured in mAh), the longer lasting your plane would be. Get a battery with a higher mAh and then your plane will last longer. However there is one thing that you must consider. Not that many battery companies post the mAh rating of the battery on the actual battery itself. Thus you may want to visit the companies website to find the exact battery specifications you need. 3.) The voltage rating of the battery must remain the same, or you risk damaging the internal electronics inside the circuit. Unless of course the circuit has a voltage regulator(Nowadays almost everyone uses a regulator). If the battery that you purchase is within tolerance I would def. use it as well. I would get any battery that has a higher maH rating and any voltage upto 10.6V. 4.) The current rating does not matter for the battery.
