The converting stage 3016 can be coupled to the bus 3060, access the bus voltage, V3, and can be up or down converting. The converting stage 3016 can buck or downconvert the bus voltage, V3, to a low voltage, V5, at an output of the converting stage 3016. The low voltage, V5, may or may not be different from the low voltage, V4, generated by the voltage controller 3006. The low voltage, V5, can be useful for driving any number of electronics and controllers. For instance, the low voltage, V5, can be used to power the second controller 3012. The low voltage, V5, can also be provided to a low voltage channel of the bus 3060, and thereby passed to the energy storage management system 3110 and any accessories on the bus 3060. For instance, the low voltage, V5, can be used to power the master controller 3174. The converting stage 3016 can have a buck topology. In embodiments, where the LED voltage, VLED, is lower than a voltage that is useful for powering accessories, (e.g., VLED<5V), the converting stage 3016 can upconvert the bus voltage, V3, to a higher voltage, such as V5=5V.
