Features

  • PRO-SERIES DOMINANT PERFORMANCE: Delivering a staggering 480CCAspecifically engineered to replace and outperform high-capacity AGM battery GYZ16H and YTX14AH-BS. At 3.20 lbs (1.45 kg), it offers elite surge current while drastically reducing vehicle weight for better maneuverability in technical terrain.
  • PHYSICAL SPECS & RUGGED FITMENT: Dimensions: 5.31x3.50x6.54in (134x89x166mm). Precise drop-in replacement for Group 14AH battery trays. Polarity: [+ -]. Features reinforced, vibration-isolated terminals designed to handle the massive current throughput required for professional-grade utility and off-road racing.
  • ELITE 8AH ENERGY RESERVE: Upgraded 8Ah capacity provides superior energy storage for heavy-duty Powersports applications. It provides the necessary reserves to support heavy-duty winches, snow plows, and auxiliary LED lighting without straining the battery core, ensuring reliable restarts after intensive accessory use.
  • POLARIS ACE & SPORTSMAN ELITE APPS: Optimized for the Polaris ACE 500 and Sportsman 500/570. The PRO-series cells maintain a high voltage plateau during cranking, providing the extra "kick" needed for high-compression engine starts in sub-zero winter temperatures where traditional GYZ batteries are at their limit.
  • KAWASAKI MULE SX & PRAIRIE APPS: Engineered for the heavy workloads of the Kawasaki Mule SX and Prairie 400. The robust internal LiFePO4 architecture and flame-retardant ABS housing provide elite protection against the extreme mechanical vibration and heat found in utility side-by-sides.
  • SMART BMS & PRECISION TELEMETRY: Integrated high-accuracy Digital Readout LCD for 0.1V telemetry. The advanced PRO-series BMS manages internal cell balancing with surgical precision, protecting the core against over-voltage and thermal stress for a lifespan of over 3000 deep discharge cycles.
  • CRITICAL VOLTAGE & CHARGER COMPLIANCE: Exclusively for vehicles with a qualified regulator (output below 15.0V). Use ONLY dedicated LiFePO4 chargers. DO NOT use lead-acid pulse chargers, as high-voltage peaks will permanently damage the internal PRO-grade BMS.

  • Awsome power
Size: 14AH-BS-PRO
Its considerably smaller than a lead acid battery but with a bit of engineering I was able to make it work in the stock location on my 07 800 sportsman. Longevity has yet to be determined but it starts the machine without issues as of now.
