You are correct about 9V batteries. A 10A short is about 90 Watts. But have you seen the specs on a LiPo Battery?
I have a 18 volt nominal 8,000 mAH LiPo battery that is rated "40C". This battery is safe and within design limits to discharge at 40 x 8,000 mA. Yes, taking 320 amps out of the battery is acceptable, the battery is designed for that. The battery can continuously supply 5.7 Kilowatts over 2 times more power then can a standard AC mains wall outlet. Of course at that rate it runs out of power in roughly one minute. But you can do a LOT in one minute. When you short the leads you get a LOT more than 320 amps A battery like that costs only about $50 today so they are available to almost anyone who wants one. > (1) A common 9V (NEDA1604 style) battery should never be left where it > might contact a metal short, and should never be left in a pocket.
