Features

Premium LiFePO₄ Cells
We deploy lithium‑iron‑phosphate cells rated for 3.2 V nominal each, assembled into modules with nominal system voltage 48 V–51.2 V. These cells deliver robust performance, stable voltage under load and superior thermal stability, meeting residential durability demands.

Integrated BMS Protection
Our built‑in Battery Management System monitors individual cell voltages with ±0.01 V precision, current at ±0.1 A resolution and temperature across −20 °C to 60 °C range. It provides over‑charge, over‑discharge, over‑current, short‑circuit and high‑temperature protections while actively balancing cells to optimise lifespan.

Modular Scalability
The architecture supports series and parallel connections: modules may start around ~5 kWh capacity and scale beyond 15 kWh. This flexibility enables single‑home installations or larger residential systems without compromising system integrity or performance.

High Power Output Capability
Rated for continuous discharge currents of 50‑100 A, with short‑term peak currents up to ~150 A (typically up to ~2.5C for ~3–5 s). This range ensures the system can handle modern appliance loads, starting motors and surge demands in home applications.

Extended Lifecycle Design
Tested for over 6,000 full charge/discharge cycles at 80% depth of discharge, with an expected service life of 10+ years under normal operating conditions.

Export‑Ready Manufacturing Quality
As a professional manufacturer, we conduct full in‑house production, implement ISO‑class quality control processes, and provide comprehensive documentation (CE, IEC, UN38.3, MSDS). The equipment is configured with RS‑485/CAN communications and meets key European and North American procurement standards.
