XS Power RSV-46 12V Titan8 Lithium Titanate (LTO) Battery
Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.
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.

The XS Power RSV-46 brings Titan8 lithium titanate performance to a 12V platform, making the LTO advantage accessible for builds that run at standard charging voltage rather than an elevated 14V or 16V system. The 12V nominal voltage means the RSV-46 integrates directly with stock alternators and charging systems without requiring any electrical system modifications, lowering the barrier to entry for competitors who want genuine lithium titanate battery performance.
Where conventional AGM batteries give up under sustained high-current demand, the RSV-46 continues to deliver — the LTO chemistry maintains voltage more firmly under load than lead-acid can match, which translates to better amplifier performance and more consistent results on the SPL meter. As a fast charge battery with serious high burst current credentials, the RSV-46 is a strong choice for builders moving from AGM to LTO for the first time, and for experienced competitors who need a reliable 12V Titan8 unit in their system.
