4.56 kWh lithium iron phosphate battery module for AlphaESS SMILE-G3 three-phase systems, fully usable at 100% depth of discharge. Stack up to 6 modules for 27.36 kWh; IP65 with aerosol fire suppression inside.

The SMILE-G3-BAT-4.5S is a 4.56 kWh LFP module for AlphaESS's third-generation SMILE system. All of its capacity is usable, as AlphaESS rates it at 100% depth of discharge, and it charges and discharges at up to 50 A, enough to match the inverter's full battery power. Each module carries its own BMS and pack balancing, so modules added later work alongside the first ones instead of being held back by them.

### Key Features

- 4.56 kWh nominal and usable capacity, 100% depth of discharge
- Lithium iron phosphate (LFP) cells, cobalt free
- 96 V nominal voltage, 50 A maximum charge and discharge current
- Expandable from one module to 27.36 kWh (1 to 6 modules in series)
- Rated for 10,000 cycles under test conditions
- Operating temperature -20 to +50 °C
- IP65 enclosure, 35 dB or less, aerosol fire suppression inside
- 610 x 212.5 x 435 mm, 53 kg

It works with the SMILE-G3-T4 to T10 inverters and stands beside them in the same 610 mm width. AlphaESS gives a 10-year battery performance warranty.
