【Fast Charging】Fast Charging capability improves efficiency, with a charging speed 3-5 times faster than AGM. It quickly replenishes to 80% in 5-15 minutes, supports high current charging (up to 14.6V), quickly restores power in emergency situations, saves charging waiting time, and is suitable for frequent short distance cycling. AGM batteries take 6-12 hours to fully charge, while lithium batteries take 1-2 hours to fully charge. If you forget to charge them in the morning, quickly recharge them before going out to ride.
VOLTAGE & CHARGER COMPLIANCE: Exclusively for vehicles with a qualified regulator delivering output under 15.0V. Use ONLY dedicated LiFePO4 chargers. DO NOT use lead-acid chargers with pulse-repair or desulfurization modes, as high-voltage peaks will permanently damage the internal PRO-grade BMS.
