Import 300ah Rechargeable 3.2v Lifepo4 Battery — Buy in Bulk from Supplier in China

This 300ah Rechargeable 3.2v LiFePO4 Battery from Shenzhen Vikli Power Source Ltd is a prismatic lithium iron phosphate cell built around LFP chemistry with model designation 3.2V300Ah-PX01. It delivers 3.2 volts nominal and 300 ampere-hours in a housing measuring 106 by 182 by 280 millimetres and weighing 8.5 kilogrammes. Standard charging proceeds at 0.3C to a 3.6V ceiling with 0.01C cutoff, while discharge runs at 0.5C to a 2.5V floor. The cell tolerates maximum charge current of 300A and maximum discharge current of 900A. Operating ranges cover 0 to 45 degrees Celsius on charge and minus 20 to 65 degrees Celsius on discharge, with storage at minus 10 to 45 degrees Celsius for under three months or 0 to 25 degrees Celsius for under one year at 25 to 85 percent relative humidity.

The prismatic format suits space-conscious pack designs where rectangular stacking outperforms cylindrical alternatives. Typical internal resistance sits at 19 milliohms, enabling efficient power delivery with manageable I²R losses. Cycle life is quoted at 1800 cycles with a note that over 2000 cycles are attainable at 80% depth of discharge. The chemistry avoids cobalt and nickel, reducing raw material cost volatility and simplifying end-of-life recycling. Cell housings are supplied in green. The supplier notes custom configurations including 36V 180Ah and 36V 200Ah assembled packs, implying welding and BMS integration capabilities.

Applications centre on solar lighting arrays, portable power stations, and electric vehicle traction. The 960 watt-hour single-cell energy content suits builders of medium-voltage residential storage or commercial solar buffers. Shenzhen Vikli Power Source Ltd ships in paper or wooden DG-compliant packaging and lists CE, RoHS, UN38.3, MSDS and KC certifications. Warranty is one year. Accepted payment channels are T/T, PayPal and Western Union. Buyers should clarify whether custom pack assembly includes cell matching, welding, BMS procurement, and final testing, or whether only raw cells are supplied.

Shenzhen Vikli Power Source Ltd operates from Shenzhen, Guangdong, China, postal code 518101. The supplier carries an imported-tier classification and harbour trust level on the platform, which indicates minimal direct verification through the marketplace itself. Response metrics show zero activity, so buyers should not rely on platform-mediated communication speed as an indicator of supplier engagement. The company accepts T/T, PayPal and Western Union, offering flexibility for smaller initial transactions but also requiring buyers to assess counterparty risk independently.

No factory size, employee count, revenue figure, or named OEM customers appear in the available profile data. The business positions itself as a manufacturer of lithium iron phosphate cells and custom battery assemblies. Given the absence of detailed verification badges, buyers should conduct their own due diligence, including direct factory video calls, business licence verification, and sample testing before committing to production orders. The supplier's willingness to customise pack voltages suggests some level of in-house technical capability, though the extent of engineering support should be confirmed directly.
