The integrated smart BMS monitors and protects every cell in real time — maximising cycle life and ensuring safe operation across all installation environments.
Automatically cuts charging current when cells reach peak voltage, preventing degradation and extending pack lifespan by thousands of cycles.
Disconnects the load before cells drop below the safe threshold, preserving cell chemistry and maintaining rated capacity over the full design life.
Instantaneously interrupts the circuit on short-circuit detection, protecting the battery pack and any connected inverter or load equipment.
Continuous real-time temperature sensing across all cell groups, with automatic load reduction or shutdown when thermal limits are approached.
Active or passive balancing ensures all cells maintain equal state-of-charge, maximising usable capacity and extending overall pack service life.
Industry-standard protocols enable seamless integration with hybrid inverters, SCADA systems, and energy management software from all major brands.
From rooftop solar homes to off-grid telecom towers — our LiFePO4 batteries integrate seamlessly across residential, commercial, and industrial settings.
Everything you need to maximise ROI, reduce energy costs, and deliver reliable, certified LiFePO4 products to your customers.
Full OEM and ODM services for distributors, wholesalers, EPC contractors, and ESS brands who want to private-label or fully customise LiFePO4 cells or battery packs for their markets.
Custom logo, brand name, colour scheme, and labelling on the battery casing, BMS display, and retail packaging.
Adjust nominal voltage (24V, 48V, 51.2V, 72V+) and total pack capacity to meet your specific system design requirements.
Floor-standing rack, wall-mount, or bespoke enclosure designs available. IP65-rated outdoor options on request.
CAN, RS485, Modbus, or proprietary protocol support to integrate with your chosen inverter or EMS platform.
Custom retail boxes, technical manuals in your language, and accessory kits for distribution-ready fulfilment.
