What is continuous? I used to repair/test amplifiers and most of them could not sustain their rated RMS output for more than 10 minutes without going into thermal, if you put a fan on them they would run for longer. Granted they are much less efficient than an ESC, but the heatsinking is HUGE compared to an ESC. This testing was done in a 72* shop with a Astron 200 amp power supply. These weren’t cheap amps either they were PPI/Orion/G&S (The HCCA’s forget it), Rockford Fosgate, Soundstream, A/D/S, and a lot of other high end amps and some cheap ones as well. The only ones I wasn’t able to thermal in 10 minutes were the ones made by Zed (Autotek/Hi-Fonics/Rodek/Earthquake). And I am not talking little amps I even had a Hifonics Colossus, and Zues and Autotek BTS7600 in for repair, Those were 900W-1800W amps

Are they rated continuously with a battery because there is no way that that small of a footprint will sustain than much power continuously? I know the heatsinking ability of the Mamba Max it sucks the heat right out of a soldering iron.

I'm just asking.
