The Mighty Max Battery YTX4L-BS is a sealed 12V 3AH SLA/AGM replacement battery built for ATVs and small powersport vehicles that need a compact, vibration-resistant power source.

This compact battery is designed to drop in for models like TaoTao, Cheetah, TForce and other ATA 110cc-series small vehicles, offering reliable starting power in a small footprint. It combines sealed lead-acid construction with AGM technology to deliver a high discharge rate and reliable performance across a wide temperature range. The pack ships with the battery and mounting screws only, so check your vehicle harness and brackets before installation.

Why choose a sealed SLA/AGM battery for powersports use?

Sealed AGM (absorbed glass mat) construction prevents spills and allows flexible mounting orientation. The chemistry tolerates vibration and repeated deep discharge better than many basic lead-acid cells, making it well suited to off-road and recreational vehicles.

• Spill-proof sealed design for safe installation in varying positions
• AGM technology supports higher discharge rates and faster recovery from deep discharge
• Durable against shocks and vibration encountered during trail use

Who is this for: Owners of small ATVs, scooters and mini-bikes — especially those who ride TaoTao, Cheetah, TForce or ATA-series 110cc models — who need a compact, sealed 12V battery with reliable cranking ability and resistance to vibration. If you want a drop-in replacement that tolerates varied temperatures and can be mounted in constrained spaces, the Mighty Max YTX4L-BS is built for that use. Confirm terminal orientation and available accessory wiring before purchase to ensure compatibility.
