Premium High Density Amprius SA112 Li-Ion Battery 19500mAh 20.8V 39A Max (TN6S3P-SA112)

Built for next-generation UAVs, robotics, and tactical platforms that need more flight time per kilogram, this premium high density Amprius SA112 battery delivers a higher energy density than SA17 (308 vs 300 Wh/kg), at a stated trade-off: a lower 39A continuous and 78A peak pulse discharge, versus SA17's 54A/90A. With a 20.8V nominal voltage and 19.5Ah capacity, it provides 405Wh of energy in a 1.4kg pack. It carries the highest cycle-life ceiling in the Amprius 21700 range: 1,000 cycles to 90% SOH at 70% DOD, or 500 cycles to 80% SOH under a harder +3.0A/-7.5A test. Optional Smart BMS ensures real-time monitoring and advanced system integration.

• Higher Energy Density: 405Wh capacity at 308 Wh/kg in a 1.4kg build
• Discharge Trade-off: 39A continuous / 78A pulse, lower than SA17's 54A/90A, in exchange for better Wh/kg
• Longest Cycle Life in the Family: 1,000 cycles to 90% SOH (70% DOD)
• Smart BMS Ready: Compatible with CANBUS, RS485, and UART for advanced monitoring and control
• Comprehensive Protection: Built-in safeguards against overcharge, over-discharge, and temperature extremes
