Wall-mount LFP battery

EG4 WallMount 314Ah Indoor: specs and datasheet

  • UL 1973
  • UL 9540A
  • UL 9540 with FlexBOSS21 and FlexBOSS18

A 16 kWh, 51.2 V, 314 Ah battery for indoor walls or floors (IP20). The datasheet lists 200 A maximum continuous discharge but only 157 A as the recommended figure, so the practical limit is lower than the headline. It is rated for 10,000 cycles at 80% depth of discharge, carries a 10-year warranty and weighs 293.2 lbs, so plan for a solid wall or a floor stand. Up to 32 units can be paralleled.
