Modular and stackable lithium battery systems for scalable energy storage.
Low- and high-voltage LiFePO4 reference platforms for staged capacity, serviceable modules and project-specific inverter integration.
A battery module is not automatically a complete energy storage system.
“Modular” may describe repeatable battery modules, a stackable enclosure, parallel low-voltage batteries or a series-connected high-voltage string. Each architecture has different BMS hierarchy, isolation, contactor, precharge, service and expansion rules.
A product title mentioning IP65 or a particular energy value applies only to that exact verified model and revision. It is not extended to every stackable system. Inverters, PCS, switchgear, HVAC, fire protection and site installation remain separate unless stated in the proposal.
Start from a real configuration, then confirm the project version.
Reference models demonstrate available form factors and engineering experience. Current drawings, component revisions, documentation, MOQ and delivery terms are reconfirmed before quotation.

Separate module, stack and complete-system decisions.
Architecture
Choose low-voltage parallel or high-voltage series based on the PCS, power and service strategy.
Expansion
Define approved module count, matching rules, commissioning and future expansion limits.
Protection & control
Review BMS hierarchy, contactors, precharge, isolation, communication and fault isolation.
Site boundary
Assign inverter/PCS, electrical protection, thermal/fire controls, installation and approval responsibilities.
What we confirm before supply.
| Module | Repeatable battery building block with defined voltage, energy, current, BMS and mechanical interface. |
|---|---|
| Battery system | Approved modules plus racks/stacks, master control, protection, cabling and operating limits. |
| Complete ESS | May additionally require PCS/inverter, switchgear, EMS, HVAC, fire protection and site engineering. |
| Expansion | Only within approved topology, firmware, model, state and commissioning rules. |
| Environmental rating | Confirmed for the exact enclosure/model; never inferred from another stackable product. |
Questions purchasing teams ask.
What makes an ESS modular?
The electrical and mechanical building blocks, BMS hierarchy, approved expansion rules and service method must be defined—not just a stackable appearance.
Can I add modules later?
Only when the system design permits it and compatibility, state, firmware, protection and commissioning requirements are met.
Is a 5kWh stackable battery automatically IP65?
No. IP ratings are model- and enclosure-specific. Submit the installation environment so the exact proposed product can be checked.
Planning a modular ESS?
Send the energy, power, PCS, voltage, environment, expansion plan, quantity and destination.
