从China供应商批量进口3.7v 4000mah Led Light Lithium Battery

This 3.7V 4000mAh lithium-polymer battery from Shenzhen Vikli Power Source Ltd is designed as a rechargeable power source for LED lighting applications. The nominal voltage of 3.7V indicates lithium-ion polymer chemistry rather than thionyl chloride, with the 4000mAh capacity suited to medium-duty commercial and residential lighting runs between charges. The cell or pack format is unspecified in the source material, so buyers should confirm whether this is a single prismatic cell, a cylindrical 18650-based pack, or a custom-shaped pouch cell.

The source describes built-in protection against overcharging and short circuits, which implies the inclusion of a protection circuit module (PCM) with integrated MOSFETs and a fuel gauge or balance function. The long cycle life claim and low self-discharge rate are standard performance characteristics for lithium-polymer cells stored at partial state of charge. The lightweight design reference and easy installation suggest a flexible or compact form factor, though exact dimensions, weight, and discharge connector type are not provided in the listing data.

Intended applications span commercial LED fixtures, residential lighting, decorative installations, and emergency lighting systems. The industrial-grade designation points toward wider temperature tolerance or enhanced vibration resistance compared to consumer-grade packs. Buyers should confirm with Shenzhen Vikli Power Source Ltd the actual cell chemistry (LiCoO2, LiFePO4, or NMC), the continuous and peak discharge current ratings, and whether the 4000mAh figure represents single-cell capacity or a multi-cell parallel configuration total.

Shenzhen Vikli Power Source Ltd is based in Shenzhen, Guangdong Province, with postal reference 518101 in the Mainland China address record. The supplier holds an imported tier and harbor trust tier designation, with a 0.00 percent response rate and zero average response hours on platform channels. This engagement profile suggests that direct email or telephone contact may be more reliable than platform messaging for commercial negotiations.

The listing presents Shenzhen Vikli Power Source Ltd as offering flexible minimum order quantities and trade terms including FOB and CIF options, with payment methods referenced as L/C and T/T. ISO and CE certifications are mentioned in the source description, though no certificate numbers, scopes, or accreditation bodies are provided. Buyers should independently verify the validity of these certifications, the supplier's actual factory location versus trading office address, and whether production is in-house or outsourced to a contracted facility.
