Brand New · Direct from OEM

Overview

The LG E78-2P12S module delivers high specific energy and strong power capability in a compact enclosure, making it an ideal building block for electric vehicles, renewables storage, and industrial power. The 2P12S layout combines fast charging with a wide operating temperature range and a large, flat cooling interface for straightforward pack-level thermal design.

Key features & benefits

  • Advanced NMC: LG Energy Solution cell technology for long life and efficiency.
  • 2P12S topology: 44.04 V nominal with high usable energy (6.87 kWh).
  • High power: up to 34.7 kW discharge, 16.3 kW charge (module-level).
  • Fast charging: reach 80% SoC in ~30–45 min under optimal conditions.
  • Thermal design: bottom-surface cooling interface, −30 °C to +55 °C operation.
  • Compact & light: 31.0 kg, ~222 Wh/kg energy density.
  • Modular & scalable: clean mechanical envelope for series/parallel pack builds.
  • Compliance ready: supports UL/CE/UN38.3 pack-level programs.

Applications & use cases

Electric Vehicles & Hybrids

Traction packs for light/medium EVs, specialty platforms, and performance builds.

Renewable Energy Storage

Residential/commercial ESS, solar/wind buffering, and microgrid stabilization.

Industrial Backup & UPS

High-reliability backup for automation, data, and critical power.

Marine & Aerospace

Compartmentalized energy with robust thermal interfaces and monitoring.

Integration notes

  • Cooling: indirect cooling via bottom surface; target interface of ~500 mm × 215.4 mm, clean, flat, and thermally coupled.
  • Clearances: allow +10 mm (no design changes) or +15 mm (with planned EVO changes) between modules for swelling and tolerance.
  • Terminals: M6 power studs; typical torque 9 Nm ±10% on clean, flat lugs.
  • Ingress: module is not sealed; ensure pack-level environmental protection (no condensation/ingress).
  • BMS: integrates well with Orion BMS families (Standard, 02, JR2 per voltage/application).

FAQs

What’s the nominal voltage of the E78-2P12S module?

44.04 V nominal (2P12S). Earlier 7.4 V references apply to smaller sub-modules, not this configuration.

Which BMS is recommended?

Orion controllers (Standard/02/JR2 as appropriate) for reliable protection, limits, and telemetry.

Is liquid cooling required?

Indirect cooling via the bottom surface is strongly recommended for sustained power and long life.
