Import 24v 12.5ah Lithium Ion Battery — Buy in wholesale FOB from Supplier in China

This 24 V 12.5 Ah lithium-ion battery pack from Changxing Yaomi Energy Tech Co., Ltd. in Zhejiang Province is built around a nominal 24 V configuration with a 12.5 Ah capacity, delivering 300 Wh of stored energy. The pack uses cylindrical lithium-ion cells arranged to service electric bicycles, low-speed four-wheelers, smart home systems, and medical equipment applications. The supplier notes injection-moulded cell assembly technology and a hardened battery case as core construction features.

The cell chemistry is lithium-ion (typical cathode: lithium cobalt oxide or lithium nickel manganese cobalt, though the supplier does not specify). Standard operating voltage ranges from 20 V to 29.4 V for a 7S lithium-ion pack, with a typical full-charge voltage of 29.4 V and cut-off at 21 V. Cycle life for cells of this grade is typically 500-800 cycles to 80 % capacity retention under standard conditions (tops 25 degrees C, 0.5 C charge/discharge). The battery management system functions include overcharge protection, though the supplier does not publish continuous discharge current or internal resistance figures. Weight for a pack of this capacity is typically 2.5-3.5 kg depending on cell format and housing material.

Buyers source this format for OEM electric mobility and stationary storage projects where 24 V is a standard system voltage. The supplier states customised voltage and capacity configurations from 12 V to 96 V and 40 Ah to 200 Ah are available, so this 12.5 Ah unit appears to be an entry-level or sample-tier offering. Packaging and carton dimensions are not stated. Buyers should confirm cell manufacturer, BMS protocol, and connector type before committing to volume, as these determine integration compatibility and safety certification paths.

Changxing Yaomi Energy Tech Co., Ltd. is located at Workshop 2, Science Park, Taihu Road, Changxing, Huzhou, Zhejiang Province, 313100, China. The supplier holds a harbor trust tier, which indicates a baseline marketplace verification status. The response rate is recorded at 0.00 % with an average response time of 0 hours, so buyers should expect delayed or minimal pre-sale communication and plan confirmation channels accordingly.

The supplier's profile focuses on customised lithium-ion battery packs across voltages from 12 V to 96 V and capacities from 40 Ah to 200 Ah, with stated applications in electric bicycles, low-speed vehicles, smart home systems, and medical equipment. The company does not disclose factory floor area, employee count, annual revenue, R and D headcount, or specific certifications such as UN38.3, IEC 62133, or UL. Buyers should request direct evidence of ISO 9001, battery testing reports, and any transport safety certifications before placing orders.
