Shenzhen Eel Battery Co., Ltd. Supplier Evaluation

Executive Summary

Shenzhen Eel Battery Co., Ltd. is a China-based supplier located in Guangdong, offering listed lithium battery cell products such as EVE MB31 314Ah, LF280K-related items, CALB 314Ah LiFePO4, and prismatic LiFePO4 cells. The company shows a relatively compact but verified operating profile, with a reported factory area of 3,200+ m², 30+ staff, and verified supplier status. Its platform credibility is strong, supported by 5 years as a Gold Supplier, Trade Assurance, Finished Product Inspection, ODM service availability, Full Customization, and Minor Customization tags. Commercial performance is also strong, with 600+ orders and CN¥18.9M+ transaction value over the past six months, plus a 4.8 store rating and 300+ reviews. The supplier appears suitable for buyers seeking battery cell sourcing with low MOQ options and platform-backed transaction protection. Key limitations are its modest staff scale and response time of ≤2h rather than ≤1h.

Detailed Analysis

1. Company Strength

Basis:
- Factory location: Guangdong, China
- Factory area: 3,200+ m²
- Employees: 30+ staff
- Verified/audited supplier: True

Elaboration:
The supplier has a documented physical factory footprint and a stated employee base, indicating an established production or operating setup rather than a purely unverified trading profile. The 3,200+ m² facility size and 30+ staff suggest a small-to-medium operational scale. The verified supplier status strengthens confidence that the company has passed some form of supplier verification.

Scoring Rationale:
The company does not present the scale of a large manufacturing group, as both factory area and staff count are moderate. However, the presence of a verified supplier status and clearly stated facility information supports a stable baseline production capability. This places the supplier above small or weak-capacity profiles but below large-scale supply-chain operators.

Final Score: 14 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 5 years
- Trade Assurance: True
- Certification/industry tags: Finished Product Inspection, ODM service available, Full Customization, Minor Customization

Elaboration:
The supplier has multiple platform credibility indicators. A 5-year Gold Supplier history provides a meaningful platform track record, while Trade Assurance improves transaction protection for buyers. The available tags also show service and inspection-related capabilities, including finished product inspection and customization options.

Scoring Rationale:
The platform credibility profile is strong because the supplier combines Gold Supplier status, multi-year platform presence, Trade Assurance, and several operational capability tags. While the data does not include external certifications beyond the listed platform tags, the available -side compliance indicators are relatively complete.

Final Score: 18 / 20

3. Business Performance

Basis:
- Orders in past 6 months: 600+
- Transaction value in past 6 months: CN¥18.9M+
- Store rating: 4.8
- Reviews: 300+

Elaboration:
The supplier demonstrates strong recent commercial activity. More than 600 orders and CN¥18.9M+ transaction value within six months indicate substantial buyer engagement on the platform. The 4.8 rating and 300+ reviews provide additional market validation within the available data.

Scoring Rationale:
The combination of high order volume, high transaction value, strong rating, and a meaningful review base supports a high business performance score. The supplier shows both transaction depth and customer feedback volume, reducing the risk of relying only on limited or unproven sales data.

Final Score: 19 / 20

4. Service Capability

Basis:
- Communication response time: ≤2h
- Full Customization: Available
- Minor Customization: Available
- ODM service: Available

Elaboration:
The supplier offers several customization-related service capabilities, including ODM, full customization, and minor customization. The stated communication response time of ≤2h is acceptable for normal sourcing communication, although it does not meet the strongest benchmark of ≤1h.

Scoring Rationale:
Customization capability is strong based on the listed tags, but response speed is slightly below the top-tier threshold. Therefore, the supplier fits the “normal response with customization capability” range rather than the highest service category.

Final Score: 8 / 10

5. Delivery Performance

Basis:
- On-time delivery rate: 97.3%

Elaboration:
The supplier’s reported on-time delivery rate is significantly above 90%, which indicates strong delivery reliability based on the available platform data. This is a positive indicator for buyers who need predictable fulfillment.

Scoring Rationale:
According to the scoring standard, an on-time delivery rate above 90% qualifies for 9–10 points. At 97.3%, the supplier is positioned near the top of this range.

Final Score: 10 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 4.8
- Reviews: 300+
- Finished Product Inspection: Listed
- Verified/audited supplier: True

Elaboration:
The supplier has a strong customer feedback base with a 4.8 rating and more than 300 reviews. Finished Product Inspection is specifically listed, which supports product quality assurance at the final inspection stage. Verified supplier status further strengthens confidence in the supplier’s quality-related credibility.

Scoring Rationale:
The quality profile is strong because it combines high customer rating, substantial review quantity, and stated inspection capability. The score is not maximized because the provided data does not include detailed product defect rates, return rates, testing reports, or named third-party quality certifications beyond the listed platform information.

Final Score: 18 / 20

Total Score

87 / 100

Procurement Recommendation

Recommended for cooperation, especially for buyers sourcing the listed LiFePO4 and prismatic battery cell products with low MOQ requirements and Trade Assurance preference. The supplier shows strong platform credibility, high recent transaction activity, good customer feedback, and excellent on-time delivery performance.

Main risks include the relatively modest staff size and factory scale compared with larger manufacturers, plus limited data on detailed factory certifications, product testing reports, and defect-rate history. Growth potential appears positive based strictly on its 600+ recent orders, CN¥18.9M+ six-month transaction value, 4.8 rating, and 97.3% on-time delivery rate.
