PRO-GRADE POWER OUTPUT: Specially tuned cells deliver an elite 180CCA—the highest amperage for the 4L-BS footprint. Ensures rapid, high-compression starts for race-ready youth bikes. ADVANCED BMS TELEMETRY: Features a high-precision Digital Readout LCD for live voltage monitoring. Smart BMS manages cell balance and provides critical protection against over-charge/discharge. FEATHERWEIGHT PERFORMANCE: At a mere 1.3 lbs, it’s the ultimate weight-saving upgrade for competitive racing (KTM/Husqvarna). Enhances vehicle flickability by shedding 2+ lbs of dead weight. EXTENDED DEPTH OF DISCHARGE: Provides consistent cranking amperage even at lower charge states. 3000+ cycles ensure the PRO series remains a one-time investment for your vehicle's lifespan. RACING-READY DURABILITY: IP66 waterproof and housed in a flame-retardant ABS shell. Engineered to survive high-impact jumps, extreme heat, and high-pressure power washes after the race. RAPID RECHARGE CAPABILITY: Accepts higher charging currents for quick turnaround times between heats. Superior energy density keeps you on the track longer with minimal downtime. VOLTAGE & CHARGER COMPATIBILITY: Exclusively for vehicles with a qualified regulator (output 15.0V). Strictly not for TaoTao series unless modified with a qualified regulator. Use ONLY dedicated LiFePO4 chargers. DO NOT use lead-acid chargers with pulse/desulfurization modes to prevent BMS failure.
