Pololu Fine-Adjust Step-Up Voltage Regulator U3V70A
Operating voltage: 2.9 - 20 V
Output type: Adjustable 4.5-20V
Features reverse voltage protection
The Pololu 4.5-20V Fine-Adjust Step-Up Voltage Regulator U3V70A generates a finely adjustable output voltage between 4.5 V to 20 V from an input voltage as low as 2.9 V while using an input current as high as 8 A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.

It's a little expensive, but if you need the high amperage capability you have to pay the price.
It's a little expensive compared to other Step-Up boards, but if you need the high amperage capability you have to pay the price. I've tried many cheap boards and they fall short when you start putting a load on them. This doesn't drop the voltage.
