And these can certainly be a viable option, IF the batteries you are testing are compatible with the (typically) narrow input range of such inverters. If you need to be able to test battery packs of arbitrary voltage and perhaps discharge to unusual (at least for typical lead-acid packs) end-of-discharge voltages, then off-the-shelf inverters may not be viable.
