TYKOOL YTZ5S Lithium Motorcycle Battery 12.8V 3Ah - Lightweight Power

In this review the TYKOOL YTZ5S Lithium Motorcycle Battery is judged as a compact, high-performance replacement for small powersports lead-acid batteries. The single biggest reason to buy is its combination of strong starting power and very low weight, making it ideal for riders and owners who want quick cranks without the weight penalty; the battery ships fully charged and installs immediately. The review finds it especially useful where frequent starts, longer cycle life and a maintenance-free solution matter.

Key Features

• Lightweight design: Weighing about 1.2 pounds, it dramatically reduces carry weight while maintaining strong starting performance.
• Cold cranking power: With 180 CCA it delivers robust cranking to start motorcycles, scooters and small ATVs reliably in most conditions.
• Long cycle life: The LiFePO4 chemistry yields over 4000 charging cycles, offering years of repeat use compared to typical lead-acid batteries.
• Built-in protection: The integrated BMS protects against overcharge, over-discharge, short circuit and extreme temperatures for safer operation.
• Fast charging: It accepts rapid charging and can recharge much faster than lead-acid packs, cutting downtime between uses.
• Maintenance-free: There is no acid, no watering and no sulfation, and it arrives fully charged and ready to install.

Who It's For

This battery is aimed at motorcyclists, scooter owners, ATV and UTV riders, and PWC users who want a lightweight, maintenance-free starter battery that delivers stronger cranking power than small lead-acid units. It is a good match for restorations, performance builds and any application where weight savings and frequent reliable starts are priorities.

Those who need very high reserve capacity for long accessory runs, or who operate equipment with different voltage or much higher current demands, should verify compatibility or look at larger lithium or lead-acid options. Also check physical dimensions and terminal polarity before replacing a different size than the listed fits.

Pros & Cons

Pros

• Very light at about 1.2 pounds, making it easy to handle and beneficial for weight-sensitive vehicles.
• Strong starting power with 180 CCA for small engines and better cranking compared to many small lead-acid batteries.
• Long expected cycle life of over 4000 charges and maintenance-free operation saves long-term hassle.

Cons

• Some users report mixed battery life in real use, so long-term performance may vary with charging habits and application.
