Custom High-Voltage Engineering

High-Voltage Power
Engineered to Project.

Custom high-voltage LFP battery systems from 76.8V to 640V — engineered for industrial DC platforms, traction systems, energy storage, and specialty high-power applications. Twelve reference builds shown below; every project is engineered to your specification.

Every pack is
a project.

Unlike our standard product lines, every high-voltage pack is engineered to spec. The table below shows twelve completed reference builds across our voltage, capacity, and power range — but no two HV projects are alike. Tell us your voltage platform, energy target, and physical envelope, and we engineer from there.

Voltage Range
76.8 – 640V
From low-HV traction to industrial DC platforms — we engineer the full range.
Power Output
4 – 50kW
Continuous rated power scaled to your application's discharge profile.
Capacity Range
32 – 300Ah
From compact 32Ah HV packs to 300Ah industrial energy banks.

Reference builds only — every HV pack is engineered to project. All packs ship with 485/CAN communication and optional remote monitoring, GPS, heating, and voice alarm. BMS has completed functional safety report; UL and CE certifications can be supported on request.

Custom Engineering

Start an HV
project with us.

High-voltage packs are project work, not catalog work. We engineer from cell chemistry and module topology through HV-BMS, contactor design, isolation monitoring, and compliance — to your voltage platform, energy target, and certification path.

Custom voltage from 76.8V up to 640V+
Module topology and series-parallel architecture
HV-BMS, contactor, pre-charge, isolation monitoring
Liquid or air cooling for high-power applications
UL / CE / UN38.3 certification support
Engineering samples before production batch
Start an HV Project

Tell us your
voltage envelope.

Every HV pack starts with a conversation. Share your target voltage, energy, physical envelope, and certification path — our engineering team will scope the pack architecture, propose a build plan, and bring it to production.
