Premium High Density Amprius SA112 Li-Ion Battery 39000mAh 41.5V 78A Max (TN12S6P-SA112)

Built for high-endurance UAV, robotics, and tactical applications that need more energy density than raw discharge power, this premium high-density Amprius SA112 battery is built in a lightweight, compact design. Featuring 41.5V nominal voltage and 39Ah capacity, the TN12S6P-SA112 provides 1,620Wh of energy at 308 Wh/kg, ahead of SA17's 300 Wh/kg. The trade-off is current: 78A continuous and up to 156A pulse, lower than SA17's 108A/180A, in exchange for 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 adds remote communication support. Ideal for professional drones and industrial platforms where endurance matters more than peak current.

• Higher Energy Density: 1,620Wh total energy at 308 Wh/kg in a 5.3kg package
• Discharge Trade-off: 78A continuous, 156A pulse, lower than SA17's 108A/180A, for better energy density
• Smart BMS Ready: CANBUS, RS485, and UART communication for advanced telemetry and diagnostics
• Longest Cycle Life in the Family: 1,000 cycles to 90% SOH (70% DOD)
• Full Protection Suite: Includes safeguards for overcharge, discharge, short circuit, temperature, and cell balancing
