I Am currently looking for battery suggestions for use in one of my projects. My projects current consumption (calculated) is
- 360mA for the main rotor 2.5A stall Link (my exact part RK370SD-4045)
- 400mA for the Mbed uC
- tail motor ? unknown specs, N30 is the only part reference
- 3x servos Link unknown mA
- sensor 100mA or less
Voltage has to be 7.2V to 12V
What I would like to know is what are the pros and cons of each battery? This link gives some great info but i want real world recommendations and things I should look out for and any other pertinent information when selecting my new battery.
Currently I have looked for batteries and have come to this conclusion, Lead Acid batteries are not a choice in this project, which leaves me with Li-ion batteries, Li-Po, Nimh, NiCd. The original battery was a 9.6V 650mAh Nimh battery and the helicopter had about 20 mins of flight time with the original equipment.
