28-300-BATTERY MODULE is a 28 V LFP spacecraft battery module for energy storage and battery management in LEO spacecraft systems.
28-300-BATTERY MODULE is Dragonfly Aerospace's 28 V LFP lithium-ion spacecraft battery module for modular energy storage and battery management in LEO spacecraft systems.[1]
Dragonfly presents the module as ITAR-free, TRL 9, and flight-proven.[1][2]
The battery uses a 9s4p LFP topology with 297 Wh capacity, 29.7 V nominal voltage, and 32 V end-of-charge voltage.[1]
Its discharge limits are 20 A, 600 W, or 2C continuously, and 40 A, 1200 W, or 4C for 60 seconds at peak.[1]
Recommended charging is at or below 12 A or 1.2C, and internal resistance is 50 milliohm.[1]
The module provides SMBus and direct control lines, operates from -10 C to +40 C, and has a recommended operating temperature of 20 C +/- 10 C.[1]
Its published lifetime and physical specifications are 5 years in LEO, TID screening above 20 kRad, 4.8 kg +/- 20 g mass, and 350 x 108 x 115 mm dimensions.[1]
The built-in BMS provides monitoring, balancing, over-voltage and under-voltage protection, SoC monitoring, transport hibernation, per-string fault isolation, and health telemetry.[1]
