ODM Large Lithium Battery Supplier & Manufacturer

LiFePO4 (LFP) offers superior thermal stability, safety, and lifespan compared to Nickel Cobalt Manganese (NCM) cells. While NCM has higher energy density, LFP systems are less prone to thermal runaway, support 6000-8000 full charge-discharge cycles (compared to NCM's 1500-2000), and contain no heavy cobalt, making them more environmentally sustainable and cost-effective over long-term operations.

Our Smart BMS uses advanced microprocessors to continuously monitor the voltage and temperature of each individual cell series. When a deviation is detected during charging or discharging, the BMS applies active or passive balancing circuits to redirect excess charge, keeping all cells aligned within a small millivolt tolerance. This prevents localized overcharging and cell degradation, extending the overall lifespan of the entire system.

For North America, key certifications include UL 1973 (for stationary applications), UL 9540A (evaluating thermal runaway fire propagation), and FCC compliance. For the European market, systems must carry CE marking, comply with IEC 62619 (safety requirements for secondary lithium cells), and meet RoHS standards. Additionally, all global shipments require UN38.3 certification to ensure safe transport by air, sea, or land.

Yes. Our industrial-grade high-voltage battery modules support multi-rack configurations connected in parallel using central control hubs. The system control unit manages the charging state of each rack to avoid circulating currents, allowing scalable capacity expansions from 100kWh up to multi-megawatt (MWh) utility-scale microgrids.

Forced-air cooling uses fans to circulate air through the battery pack. This is cost-effective but less efficient for high-density configurations. Liquid cooling uses cooling plates and circulating glycol-water mixtures to directly absorb heat from the cells. Liquid systems maintain tighter temperature control, keeping temperature differentials between cells under 3°C, which is critical for preventing thermal degradation in high-power applications.

With Grade A cells and proper BMS thermal management, our systems deliver over 8,000 cycles at 80% Depth of Discharge (DoD) before capacity drops to 80% of its nominal value. Under standard daily cycling conditions, this translates to a service life of 15 to 20 years, backed by our 10-year warranty program.

Our ODM workflow begins with structural and electrical modeling. We design custom mechanical enclosures using CAD software to fit unique spaces, and choose cell arrangements that meet the voltage and current requirements of the motor. We also test all configurations for extreme vibration, shock, and thermal stresses to ensure reliable operation in harsh environments.

Our large-scale batteries include comprehensive physical protections: surge protection devices (SPDs) to guard against lightning-induced transients, fast-acting high-voltage fuses for short-circuit protection, and integrated DC contactors managed by the BMS. The system can isolate the battery bank within milliseconds if a ground fault or overcurrent condition is detected, safeguarding personnel and connected equipment.
