Import 51.2v100ah Lithium Battery Wall — Buy in wholesale FOB from Supplier in China

The 51.2V100Ah Lithium Battery Wall from Shenzhen Lemax New Energy Co., Ltd employs LiFePO4 chemistry housed in an ABS enclosure, delivering 5.12 kWh nominal energy at a 200A maximum charge and discharge current. An intelligent BMS manages cell health, while a 1.2A active equaliser targets voltage differentials as small as 0.05V for rapid string balancing. Standby self-consumption is rated at 4mA, and the pack automatically cuts output after 30 days of inactivity or on manual command. The unit is positioned for residential solar, commercial energy storage, UPS backup, and mobile off-grid applications including RV installations.

The 200A current capacity translates to roughly 10.2 kW continuous power, enabling direct coupling with high-demand inverters without parallel expansion. The 1.2A equaliser is notably aggressive compared to typical passive balancing circuits, which may reduce the time cells spend at elevated voltages and moderate thermal stress. ABS housing offers adequate mechanical protection for indoor or sheltered outdoor mounting, though UV resistance and IP rating should be confirmed for exposed installations. The automatic output cut-off after 30 days serves as a safety feature during transport or seasonal disuse, but importers should verify restart procedures to avoid field support issues.

Target buyers span solar distributors, off-grid system integrators, RV equipment suppliers, and commercial UPS providers. The pack's compatibility with solar charge controllers and hybrid inverters depends on communication protocol support, which buyers must confirm against their hardware. Compared to lead-acid alternatives, the cycle life and depth of discharge capability reduce total cost of ownership in cyclic applications. Importers should request test data for calendar aging at elevated temperatures, as this parameter is often more limiting than cycle count in stationary installations.

Shenzhen Lemx New Energy Co., Ltd is registered at A301, Jian Creative Industry Center, No. 54 Jizheng Road, Buji Street, Longgang District, Shenzhen, Guangdong Province, China. The supplier carries a harbor trust tier with a 0.00% response rate and zero recorded average response hours, indicating no response history is available on the platform. Prospective buyers should initiate direct contact via email or telephone to assess communication clarity, technical support capability, and English-language documentation quality before advancing to sample orders.

The company profile does not disclose establishment year, factory floor area, employee count, annual revenue, or client references. No ISO certifications, factory audit records, or product test reports are visible in the source data. The Buji Street location in Longgang District places the supplier within Shenzhen's electronics manufacturing belt, with proximity to Yantian port for containerised export. Importers are advised to conduct a virtual or on-site factory audit, request reference customers in their target market, and verify that the manufacturing facility assembles packs with consistent cell sourcing rather than ad-hoc procurement.
