Differances in bk 12020 Warrior and 9920

Anyone know what those caps are for? They're a bit small for load filtering, maybe they are there to filter noise/spikes?

By the way, using smaller caps that total the same capacitance as one cap is better because they can produce quicker transient response. Of course, if the circuit doesn't need that feature, it's a moot point.

And speaking of caps, I wonder if using say, a 500,000uF cap on the batteries would help reduce voltage lag when high current draw is being pulled. Of course, this size cap would be somewhat large and relatively heavy, so this is just for speculation.
