Compact 12-Volt Lithium Titanate Power Cell

Powering high-performance audio systems and demanding mobile electronics requires a highly advanced, rapid-discharging energy source. XS Power PWR-S5-20Q is an elite 12-volt lithium battery featuring sophisticated Lithium Titanate Oxide (LTO) chemistry for incredibly fast charge cycles and immediate energy delivery. Designed as a direct-fit replacement for standard 20Q configurations, this ultra-lightweight module instantly maximizes your vehicle's electrical performance while shedding massive weight compared to cumbersome lead-acid alternatives.

Maintaining a rock-solid voltage during extreme electrical spikes is critical for preventing amplifier clipping and maximizing audio clarity. Built to support heavy-duty accessories and competition-grade stereos, this highly efficient cell delivers staggering max pulse amps to effortlessly keep pace with demanding bass hits. Whether acting as a high-capacity primary starting battery for powersports applications or as a dedicated secondary power bank, the completely sealed, maintenance-free PWR-S5-20Q includes premium terminal hardware to guarantee a highly secure, low-resistance connection.
