Acoucou 12V 4.25Ah Lithium Battery 250A Powersports

Description

Product Overview

The Acoucou YTX14‑BS is a high‑performance 12V 4.25Ah lithium‑ion battery engineered for powersports applications. Utilizing advanced sodium‑ion chemistry, it delivers up to 250 amps of starting current—approximately twice the power of traditional lead‑acid units and ten times the number of starts. The compact 5.91″ × 3.43″ × 5.87″ design replaces EST‑TX14, ETX14‑BS, CTX14‑BS and similar models, weighing only 3.04 lb. Built‑in smart protection manages rapid charging from 20% to 80% in 15 minutes while safeguarding against over‑voltage, short‑circuit, and temperature extremes.

Usage

This battery excels in demanding environments, from frigid winter mornings to scorching summer trails. Whether you ride a sport bike, ATV, UTV, personal watercraft, or operate a generator, the YTX14‑BS provides consistent power output across a temperature range of -40°F (-40°C) to 176°F (80°C). Its maintenance‑free, sealed construction eliminates the need for periodic water checks, making it ideal for off‑road enthusiasts, fleet operators, and anyone seeking reliable performance without hassle.
