XS Power RSV-S6-30Q 5000w Titan 8 14 Volt LTO Lithium Car Battery, Max 1000Amps

The RSV-S6-30Q is a 14V lithium titanate oxide (LTO) reserve module built for capacity rather than cranking. It holds 276 Wh, 20Ah nominal (60Ah compared directly to AGM), and supports burst output up to 12,000W for five seconds. Cranking output is 500 amps, about 750 in AGM terms, with 1,000 max amps available.

The job of an RSV module is voltage stability under long, heavy demand: the kind a large amplifier rack pulls on sustained bass, or a winch pulls under load. Built-in 2/0 AWG bussing gives up to four positive and four negative hidden connections per module with no externally exposed bussing, while two accessible top terminals and four series or parallel expansion terminals let you stack modules into a bank of nearly any size or voltage. The BCI Group 30/30L case with L/R polarity fits the factory battery position, and the module carries a one-year warranty.

Pair it with a Titan8 PWR cranking module when a build needs both fast starts and deep reserve, or run it as a standalone bank behind the amplifiers. Titan8 modules are also offered in BCI direct-fit versions, fully insulated with temperature monitoring built in, for the factory under-hood position.

The module weighs 9.25 lb and measures 8.07" L x 7.21" H x 7.64" W. M6 terminal hardware is included.
