tell me more

With so many advantages over lead-acid batteries, maybe it's time to choose Lithium-ion batteries for your large 48V storage system? The BYD Battery-Box Premium LVS is a modular lithium iron phosphate (LFP) battery pack for use with an external inverter (we highly recommend Victron Energy Multiplus or Quattro inverter chargers with these units).

Between 1 and 6 battery modules can be used in a single stack to give 4.0 to 24.0 kWh usable capacity.

Alternatively, up to 16 Battery-Box LVS stacks consisting of between 1 and 4 battery modules can be connected in parallel to give a maximum capacity of 256 kWh. Additional LVS modules or parallel stacks can be added at any time to increase capacity.

1 PDU base and cover is required for each battery stack and 1 BMU per system/inverter (purchase separately)


  • Expandable from 4kWh to 256kWh
  • Maximum flexibility for any application with up to 64 modules connected in parallel
  • Cobalt Free Lithium-iron Phosphate (LFP) Battery: giving maximum safety and performance
  • CE and TUV certified BYD B-Box module meets the highest safety standards
  • Proven for use in telecom, off-grid and energy storage/self consumption applications worldwide
  • Patented Internal Plug Design: requires no additional wiring
  • Amazing and strong 10 year warranty

Lead-acid batteries may fail prematurely due to operating in deficit mode (rarely or never fully charged) or if left partially charged or fully discharged. A lithium-ion battery does not need to be fully charged, with service life even slightly improved by partial charge. This means it is great for heavy duty usage such as liveaboard boats, motorhomes, caravans and off-grid applications.

  • Nominal voltage: 51.2V
  • Operating voltage: 40-57.6V
  • Nominal Capacity: 4kWh
  • Round-trip efficiency: >95%
  • Ambient Temperature: -10C - +50C
  • Max continuous output current: 65A
  • Peak output current: 90A, 5 secs
