Custom High-Voltage Battery Packs
Voltaplex is proud to design and manufacture high-voltage battery packs for energy-intensive applications. We build each pack to meet the performance and safety requirements of commercial, industrial, and transportation systems.
Our high-voltage lithium-ion battery options are available in configurations starting at 10 kWh, with scalable options exceeding 100 kWh depending on project requirements. By operating at 400 volts and above, Voltaplex ensures the HV battery pack enables faster charge cycles, reduced current draw, and lower energy loss across applications.
What is a High-Voltage Battery Pack?
A high-voltage battery pack is an energy storage system that operates above 400 volts, allowing for greater electrical efficiency and more consistent power output under high loads.
Unlike low-voltage systems, which require larger conductors and higher currents, high-voltage configurations maintain system stability with less thermal loss and reduced strain on support components.
A high-voltage battery system is well-suited for applications where electrical infrastructure must remain intact. This includes systems that store surplus energy for rapid deployment, supply grid-tied backup during outages, or drive electric energy in heavy-duty transport.

Key Benefits of Voltaplex High Voltage Battery Packs
When your system demands constant performance in a compact layout, Voltaplex high-voltage lithium-ion battery options are crafted for this kind of utilization and beyond.
We’ve meticulously designed each HV battery pack to minimize thermal buildup while maintaining voltage control across the full discharge cycle. Our design reduces heat management complexity and supports higher power throughput in a smaller enclosure.
Clients using our high-voltage battery systems report increased runtime predictability and great layout flexibility: two things every industrial professional can be proud of.
Our HV battery systems also support simplified integration by reducing wiring volume and improving compatibility with modern electronics. A high-voltage battery management system is embedded to monitor each pack segment, ensuring current balance and continuous thermal regulation.
This results in a longer usable lifespan, fewer service disruptions, and consistent output in fixed and mobile settings.
HV Battery Pack Applications
Voltaplex high-voltage battery systems are used where traditional energy storage systems fall short. Their compact design and rapid power handling capabilities make them practical for numerous applications, including the following:
- Commercial and industrial energy storage installations requiring compact, high-output systems
- Integrated power cabinets for off-grid or supplemental solar installations
- EV infrastructure supporting high-speed charging and vehicle power delivery
- Backup systems for grid-tied sites where low-voltage solutions are impractical
- Modular units deployed in scalable smart grid configurations or containerized storage
Each of these applications relies on voltage stability and long-term performance, factors that Voltaplex’s HV battery packs consistently demonstrate.
Modular and Scalable Features
Voltaplex professionals build our high-voltage battery packs with a modular layout that allows system scaling without any redesign necessary.
Units can be connected to increase voltage or capacity as project requirements evolve, reducing both installation time and cost.
Each pack has a high-voltage battery management system that handles safety, voltage balance, and fault isolation across modules. And, as your system expands, performance and protection remain as constant as ever.
