Description

Authorized dealer

High-Output Group 34 14-Volt Lithium Titanate Battery

Powering extreme automotive electronics and competition-level audio systems requires an incredibly robust and fast-discharging energy source. XS Power PWR-S6-3400 is a premium 14-volt lithium battery utilizing advanced Lithium Titanate Oxide (LTO) chemistry to deliver unparalleled charge and discharge rates. Designed to standard Group 34 dimensions (approximately 10.24" long, 6.81" wide, and 7.83" high), this lightweight, direct-fit module drops seamlessly into factory mounting locations, allowing you to maximize your vehicle's electrical capabilities while shedding significant weight compared to traditional, cumbersome lead-acid power cells.

Maintaining a rock-solid voltage during extreme current spikes is absolutely critical for preventing amplifier clipping and ensuring distortion-free sound reproduction. Engineered to comfortably support massive aftermarket stereos and heavy-duty accessories, this ultra-efficient power cell effortlessly delivers staggering max pulse amps to keep up with intense bass notes and heavy electrical loads. Whether acting as a high-capacity primary starting battery for a high-compression engine or as a dedicated secondary power source, the fully sealed, maintenance-free PWR-S6-3400 includes robust terminal hardware to guarantee a highly secure, low-resistance connection across your entire electrical network.
