Re: Running Mach2 from battery at 24v
If you don’t need to slew at high speed, you might not find a great advantage in boosting your battery voltage to 24V.
While it might seem appealing to get room as far as power is concerned, be aware that a dc-dc boost converter won’t give you much than what your battery can already provide. In fact, any voltage conversion (buck or boost) will result in loss of power in the system. Your load (the mount in your case) will consume about the same amount of power (more voltage and less current at 24V than 12V) but the inefficiencies (as small as they can be, say 5% like in the model you are considering) will be totally lost, resulting in a lost of autonomy of your battery-powered system.
Also keep in mind that some dc-dc converter designs require a minimum load to work (or start working) and perform at their nominal specified efficiency... So depending on what else you plan to power from 24V oversizing might not be your friend...
