Premium High Power Amprius SA124 Li-Ion Battery 20000mAh 50.4V 200A Max (TN14S4P-SA124)

Built for missions where peak current draw matters more than endurance, this premium high power Amprius SA124 lithium-ion battery is the highest-discharge cell in Dan-Tech's Amprius lineup. With a 50.4V nominal voltage and 20Ah capacity, it delivers 1,008Wh of energy while supporting 200A continuous discharge and up to 720A for 2-second peak bursts. The trade-off for that power ceiling is a 250 Wh/kg energy density, below Dan-Tech's high-density Amprius cells (SA17 at 300, SA112 at 308, SA08 at 360 Wh/kg). Optional Smart BMS ensures real-time monitoring and advanced system integration.

  • Highest Discharge Rating in the Amprius Lineup: 200A continuous (10C) and 720A for 2-second peak bursts (36C)
  • Power-First Trade-off: 250 Wh/kg energy density in exchange for burst current headroom, below the 300–360 Wh/kg of SA17, SA112, and SA08
  • Compact for Integration: 100 × 80 × 350 mm size optimized for aerial and robotic platforms
  • 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
