I am looking for a battery that has either 9V or a voltage that I can connect in series to make 9V. My load will draw about 150mA, but I would like to be on the safe side and have the battery discharge current be at least 200mA.
Here is the tricky part. This battery will go on a medium RC helicopter to power electronic sensors for a robot I'm making.
I am guessing on this and will know more details after the helicopter actually arrives and I do some weight tests, but the weight of the battery (or batteries in series) should be about 20 grams at the most.
I don't care if its a primary cell or secondary cell as long as its not ridiculously expensive.
Does such a battery exist?
Thank you
