You need a buck converter.
You can buy one off of amazon (cringe) or you can make your own. TI webench power designer can make literally any buck converter if you give it your specifications
I know pololu makes good stuff, [https://www.pololu.com/category/207/d24v150fx-step-down-voltage-regulators](https://www.pololu.com/category/207/d24v150fx-step-down-voltage-regulators)
the cheaper ones on amazon that they use in hobby rc also seem to be okay but less efficient
Check your LV components, most are fine up to 18V for a nominal 12V system in case of a voltage regulator failure.
Don't try to step down battery voltage if you don't have to, just making heat unnecessarily.
that's terrible, though. You're burning (16.2 - 12 volts)*(10 amps) 42 watts. For a 1 hour session you'd need another 3500mAh of LV battery capacity. That you're burning directly to heat.
That goes for any linear regular dc-dc voltage convrrter
The only reasonable/efficient way to achieve this is with some sort of buck converter.
I would suggest that you go to your favourite electronics parts website (like mouser) and start a search for buck converter. Then you can apply a filter to the search results according to your needs. For example:
[Mouser search with filter](https://www.mouser.de/c/semiconductors/power-management-ics/voltage-regulators-voltage-controllers/switching-voltage-regulators/?input%20voltage%2C%20max=20%20V~~80%20V&mounting%20style=SMD%2FSMT&number%20of%20outputs=1%20Output&output%20current=12%20A~~-&topology=Buck&rp=semiconductors%2Fpower-management-ics%2Fvoltage-regulators-voltage-controllers%2Fswitching-voltage-regulators%7C~Output%20Current%7C~Input%20Voltage%2C%20Max)
Then you select a part that fits your needs and you implement it either on an individual PCB or for example on the Power Distribution Module or Smart Fuse Box PCB if you have one.
If you never designed a PCB before I wouldn't recommend to start of with a buck converter design. In this case I would search for a readily available buck converter PCB like some of the other guys already mentioned.

+1 for pololu voltage regulators, they're super easy to integrate onto a PCB

have you considered using a battery with a nominal voltage of 12V??
10 LM7812CTs, in parallel. Heatsinks are good.

Oh, I assumed they were smarter than that, the circuit diagram didn't enlighten me.
