A lithium battery is a single sealed unit, there is no way to tap a 12V output from it directly. This converter takes the 48V (or 36V) output of the battery and steps it down to a stable 12V supply for your accessories.

Connecting a step-down converter to the battery's output terminals does not affect warranty coverage as long as the converter is wired correctly and does not create an electrical fault that damages the battery.
