# What does the bsp (battery status processor) accessory do?

**Warning, the bsp is for lead acid batteries.** When activated, the bsp manages the global battery charge current, measured directly by the bsp in the battery, and controls the variostring, variotrack and xtender charge currents. This control will implicitly apply a solar priority strategy. Thus, the current will be taken primarily from the variotrack and variostring.
