I am planning to buy a 12v battery for my ultrasonic inverter. 3S configuration with high AH value lithium-ion isn't cheap and availability is very scarce in my locality.
I came across "ORANGE Li-Fe 50Ah 3.2V LITHIUM IRON PHOSPHATE BATTERY PACK" costing just under 40 USD. I want to if it is a good idea to use a step-up boost converter with this battery to output 12 volts to power my inverter? Are there any risks involved with this setup? Any cautionary measures to be taken care of? ? Suggestions, please? Thank you.

3.2V is not a good input voltage for a high power step-up converter or inverter.
One 50 Ah cell will not have more energy than a 4S battery with 12.5 Ah cells.
The 4S solution is much better because it will have less switching losses.
