Delivering up to 180A CCA, the TYKOOL YTX4L-BS-PRO provides fast, confident starts and clearly outperforms standard lithium options (120A) and traditional lead-acid batteries (80A). Built for long-term use, it also offers an impressive 3,000-cycle lifespan—surpassing standard lithium (2,500 cycles) and far exceeding lead-acid (~300 cycles)—making it a reliable, high-performance upgrade for serious riders.
The TYKOOL YTX4L-BS-PRO lithium battery is designed to cut weight and eliminate upkeep. At only 1.2 lbs, it’s dramatically lighter than a typical lead-acid battery (about 3 lbs), making handling and installation easier. It’s also completely maintenance-free—no activation, no acid, no leakage concerns, and no routine servicing required. Shipped fully charged and ready to install, it delivers clean, hassle-free power for motorcycles and other powersports vehicles.
The TYKOOL YTX4L-BS-PRO High-Performance LiFePO4 Motorcycle Battery integrates a smart Battery Management System (BMS) to help keep operation stable and safe. It delivers key protections such as over-charge, over-current, short-circuit, and over-discharge safeguards, plus cell equalization/balancing for consistent energy output and long-term reliability. For added control, the digital readout displays both State of Charge (SOC) and voltage at a glance, making it easy to track battery status and maintain peak performance.
Built for an easy drop-in upgrade, this lithium battery is made in a 1:1 OEM battery size, so it installs cleanly with no trimming or modifications. The solid brass terminals provide strong conductivity and added durability for a secure, stable connection. With compact dimensions of 4.45" × 2.79" × 3.38" (113 × 71 × 86 mm), it maintains a perfect fit while delivering dependable, high-performance power across a wide range of vehicles.
Built for modern riders, the TYKOOL LiFePO4 lithium battery delivers reliable starting power and long-lasting durability across a wide range of applications—including motorcycles, ATVs, UTVs, PWCs, and scooters. Designed as a direct upgrade, the YTX4L-BS-PRO Battery replaces common OEM sizes such as YTX4L-BS, YTZ5S-BS, YB4L-A, and YT4L-B, making fitment simple and worry-free. With advanced engineering and safety-focused testing, TYKOOL provides a lightweight, high-performance power solution that’s ready to keep you moving—on the road, trail, or water.
