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.
