The 12v lane is ubiquitous, and standardized. Supercaps are inefficient when it comes to storage per weight and volume, discharge rate too.

Both lead acid and supercaps are not even remotely comparable to the main liion battery, they're suppliments, and not interesting ones

The supercaps aren't for long-term storage - just long enough to allow the extra juice to flow back to the batteries. Racing cars sometimes do that with flywheels.

As for 12V, all one needs is a regulator. Unless you have a long-term supply contract (that, I bet, won't be renewed for too long), a lead-acid battery is just dead weight.
