Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

Dialing in your multi-battery system starts with a power module that understands the demands of serious car audio — and the XS Power XSP311 is exactly that. Designed to function as a dual battery isolator in builds where two power sources need to coexist without robbing each other, the XSP311 brings intelligent voltage control module logic to even complex electrical configurations.
Daily-driver installs benefit from its battery protection logic, while competition vehicles appreciate its ability to keep power delivery consistent under sustained load. The XSP311 integrates cleanly with XS Power batteries and complements any high-current car audio power module arrangement you are running under the hood or in the trunk.
