[Paparazzi-devel] Lisa/L Power Consumption |

Hello folks,
I will order batteries to supply Lisa/L (right now, it is under construction xD), and I wonder how many amperes it consumes with a typical setup of:
GPS + Radio Modem + Overo + IMU
I know that this is a very general setup, and it depends on what ICs are finally selected. But I guess it could help me if somebody can tell me his power consumption experience using Lisa/L.
I was thinking in LiPo batteries (different from the motor battery), but now I have to figure out its discharge rate and mA/h. The compromise is between size/weight and autonomy of Lisa/L.
By the way, does LM317M heat itself a little bit? (12Vin (or even more from a 3S LiPo) - 6.5Vout) x 0.3A (lets say this is what analog devices consumes, "worst case condition") = nearly 2Watts.
Cheers
