XP750-SE

The XS Power XP750-SE is a compact 12V AGM secondary battery in a black case, adding 750W of stored power with 750 max amps, 22 amp hours, and 28 minutes of reserve capacity. The blacked-out finish suits builds where the battery is visible and the look matters as much as the numbers.

As a supplemental battery, the XP750-SE handles the loads that make a single-battery system sag: one amplifier working hard, an added light bar, cabin electronics, or a small power inverter. Because the current comes from the cell instead of the starting battery, voltage stays steady during bass peaks and you still have cranking power when the music stops.

Absorbent Glass Mat construction suspends the electrolyte in fiberglass, so the battery is sealed against spills and moisture and can be mounted inside the vehicle or in an exposed spot that would rule out a flooded battery. The same design resists sustained vibration from rough roads and high-output subwoofers.

Size is where this cell earns its place: 7.13 by 3.03 by 6.57 inches and 14.5 lb, narrow enough to tuck into a show-quality amp rack, under a seat, or behind a trim panel. M5 terminal hardware is included and a two year warranty covers it.
