Rack-Mount & Cabinet Battery Systems

If you are an integrator, you do not want our enclosure and our EMS — you want a battery module that fits a standard rack, reports its data honestly, and parallels predictably.

Built for integrators, not for end users

Integrators buy differently from end users. You already have an enclosure, an EMS and a customer relationship. What you need from a battery supplier is a module with stable mechanical dimensions, a documented communication interface and consistent behaviour when you parallel them.

Our rack platform is built to that brief:

Standard 19-inch form factor. 3U or 4U, with the terminal and communication ports in fixed positions so your cabinet wiring does not change between batches.
Documented registers. Every value the BMS exposes is listed in the protocol document — cell voltages, temperatures, SOC, SOH, alarms and limits. No reverse engineering.
Predictable paralleling. Up to 16 modules in parallel with automatic address assignment and current sharing within a stated tolerance.
Fixed mechanical interface. The same mounting holes, depth and mass, batch to batch, so your enclosure design stays valid.

Why consistent dimensions matter more than a better cell

An integrator's real cost is engineering time, not cell cost. A module that gains 2 % energy density but grows 8 mm in depth invalidates a cabinet design, a shipping carton and a mounting jig.

We freeze the mechanical envelope for the life of a platform and publish the changes in advance. When a platform does change, we support the old version alongside the new one for a defined period so you can run down stock.

Models with links have detailed specification pages; unlisted models are also available on request. Capacity and quantity should be sized by our engineers against the actual load — never by nameplate rating alone.
