从China供应商批发进口12v 300ah Lifepo4 Lithium Ion Battery — FOB条款

This 12V 300AH LiFePO4 lithium ion battery from Keheng New Energy Technology (Shenzhen) Co., Ltd. delivers 3840Wh of nominal energy at a 12.8V nominal voltage, housed in a plastic case measuring 520 x 260 x 230mm and weighing 23.4kg. The lithium iron phosphate chemistry provides a stable cathode structure with a typical cycle life exceeding 2000 cycles at 80% depth of discharge, significantly outperforming conventional lead-acid batteries in both lifespan and energy density. The listing specifies a continuous charge and discharge current of 150A, a maximum pulse discharge of 200A, and an internal resistance of 30mΩ, with cell-level end-of-charge and end-of-discharge voltages of 3.75V and 2.1V respectively.

LiFePO4 chemistry is widely recognised in the energy storage sector for its thermal stability, non-toxic iron-based cathode, and resistance to thermal runaway compared to other lithium-ion variants such as NMC or LCO. A typical 12V LiFePO4 battery of this capacity uses a 4-series (4S) cell configuration, with each cell at a 3.2V nominal voltage, and includes a built-in battery management system (BMS) to handle cell balancing, overcharge protection, and over-discharge cutoff. The 23.4kg weight is notably lighter than a comparable 300AH lead-acid deep-cycle battery, which would typically weigh over 70kg, making this unit more practical for mobile and off-grid installations.

Buyers sourcing this battery for solar energy storage, RV and marine power systems, or backup power applications should confirm the BMS specifications, including maximum continuous current limits and low-temperature charging cutoff, with the supplier before ordering. Keheng New Energy Technology (Shenzhen) Co., Ltd. operates from Floor 3, Jinlong Industrial Zone, Sanzhong Village, Qingxi Town, Dongguan, Guangdong Province, and holds a 'harbor' trust tier on the platform. The listing does not specify MOQ, pricing tiers, or lead times, so these trade terms should be negotiated directly with the supplier.

Keheng New Energy Technology (Shenzhen) Co., Ltd. is registered at Floor 3, Jinlong Industrial Zone, Sanzhong Village, Qingxi Town, Dongguan, Guangdong Province, China. The company holds a 'harbor' trust tier on the platform, though the listed response rate is currently 0.00%, indicating that buyers should use direct contact methods or allow additional time for initial correspondence.

The listing focuses on LiFePO4 lithium ion batteries for energy storage and motive power applications, with this particular unit targeting solar, RV, marine, and backup power markets. No information on the company's founding year, manufacturing capacity, export history, or workforce size is provided in the listing, so buyers seeking to assess supplier capability should request these details directly or arrange a factory audit before placing large orders.
