SB50, SB120, SB175 and SB350 constitute the full mainstream product lineup of single-pole Anderson high-current battery connectors, covering current specifications from 50A small-power applications up to 350A ultra-heavy-duty industrial power connection scenarios, widely applied across solar energy storage systems, electric forklift fleets, recreational vehicles, mining equipment, medical power supplies, data center backup power and off-grid portable power stations worldwide. Sourcing a stable, reliable Chinese supplier capable of supplying all four SB series specifications simultaneously with consistent quality, complete international certifications, flexible bulk wholesale policies and timely after-sales support is a core demand for international bulk distributors, energy storage system integrators and industrial equipment manufacturers. After years of market verification by global overseas purchasers, a tiered list of trusted Chinese suppliers specializing in full SB series connector supply has been formed, categorized into professional brand manufacturers, large-scale wholesale stock suppliers and customized OEM production enterprises, each suited to distinct procurement scenarios including long-term project cooperation, spot bulk wholesale and private brand customized production respectively.

 Tier 1 Professional Brand Manufacturers (Highest Quality & Full Certification for Industrial Projects)

This category of suppliers develops independent molds for the entire SB50-SB350 product range, adopts high-grade raw materials, establishes strict internal quality control systems and holds comprehensive global electrical safety certifications, serving large industrial energy storage projects, OEM equipment supporting orders and high-standard overseas market sales with zero tolerance for quality fluctuations. Two leading representatives are Guangdong Send Electronic Technology Co., Ltd. and AITM Power Co., Ltd.

Guangdong Send Electronic Technology (SEND TECH), based in Dongguan, Guangdong, is widely recognized as the most reliable full SB series connector supplier in China for industrial-grade applications. The company has spent over 15 years optimizing mold precision and material formulations for SB50, SB120, SB175 and SB350 connectors, with all dimensional parameters fully aligned with original Anderson standards to ensure 100% interchangeability. SB50 (50A) adopts compact housing design for small battery packs and portable power supplies; SB120 and SB175 serve medium-current energy storage and electric vehicle power connections; SB350 ultra-high-current plugs are reinforced with thickened terminals and heavy-duty locking structures to sustain continuous 350A current without overheating for mining machinery and large-scale grid energy storage cabinets. All four models pass UL, CE, RoHS, REACH and CSA certifications mandatory for European and North American market access. Housings use imported UL94-V0 flame-retardant PA66 plastic with anti-UV and low-temperature resistance properties, applicable to extreme outdoor environments ranging from -40℃ to 125℃; internal terminals are oxygen-free copper alloy with double-layer thick silver plating, drastically reducing contact resistance and heat generation under long-term high-current load. The supplier maintains balanced production capacity for all four specifications, supports mixed batch ordering of different current models, offers tiered volume discounts based on total mixed order quantity, and provides 2-year official quality warranty for all bulk shipments. For long-term contracted clients with monthly recurring orders, the enterprise reserves dedicated production capacity to guarantee stable delivery even during peak industry demand seasons, eliminating stock shortage risks.

AITM Power Co., Ltd., located in Shenzhen Bao’an District, is a trusted supplier prioritizing large spot inventory and fast global delivery for the entire SB series lineup. The factory stores massive finished goods inventory of SB50, SB120, SB175 and SB350 connectors year-round in its bonded warehouse, capable of dispatching mixed orders within 24 hours for urgent overseas orders without waiting for production lead times. Its product positioning balances industrial durability and cost performance, perfectly suited for regional wholesale distributors requiring frequent scattered replenishment of multiple SB specifications. All products undergo full electrical aging testing before shipment, hold CE and TUV certifications, and offer flexible MOQ policies allowing small mixed orders of different current ratings for first-time cooperative buyers. The supplier’s prominent advantage lies in professional international logistics coordination, capable of consolidating mixed goods and arranging unified shipment to multiple destination countries for global distributors.

 Tier 2 Large-Scale Wholesale Stock Distributors (Cost-Effective Spot Bulk Wholesale)

For buyers focusing on consumer-grade new energy products, RV accessories and portable power station wholesale with moderate quality requirements and priority on low bulk prices, verified large wholesale suppliers based in Shenzhen Huaqiang North Electronic Market and Ningbo Electric Appliance Industrial Zone are ideal choices. Shenzhen Zhide Cable Technology Co., Ltd. is the most reputable supplier in this segment, supplying full SB series connectors alongside supporting pre-crimped wire harness assemblies. The company maintains huge spot stocks of SB50 to SB350 plugs, adopts optimized cost material configurations meeting basic CE and RoHS standards, and delivers highly competitive unit prices for bulk orders above 5,000 pieces. It excels in one-stop supporting services, allowing buyers to purchase connectors, matched battery cables, sealing accessories and installation tools in a single order, greatly simplifying procurement procedures for small and medium-sized importers.

 Tier 3 OEM Customization Suppliers (Private Brand Exclusive Production)

Ningbo FPIC Electronics Co., Ltd. serves global brands requiring customized SB series connectors with private logos, exclusive housing colors or structural modifications, possessing powerful mold development and revision capabilities. Buyers can entrust the factory to print their own brand trademarks on SB50-SB350 plug housings, adjust internal terminal structures for proprietary equipment, or develop special anti-corrosion versions for marine environments. The factory amortizes mold development fees for long-term stable clients, ensuring favorable unit prices for mass customized orders while maintaining consistent dimensional compatibility with standard Anderson SB series products.

 Key Criteria to Judge Supplier Reliability

Complete coverage of all four SB specifications with synchronized production and inventory capacity;

Valid international safety certification documents for each model, verifiable via official certification institutions;

Positive long-term overseas buyer reviews and stable export transaction records;

Clear defective product replacement, re-delivery and quality after-sales clauses stipulated in formal contracts;

Transparent pricing system without hidden fees for mixed batch orders and customized services.

Avoid unreliable suppliers that only produce partial SB models, hold no formal certifications, or offer extremely low prices by cutting material grades, which will lead to frequent contact burnout, loose mating and safety hazards during application. In conclusion, selecting a reliable Chinese SB series connector supplier should match procurement scenarios: industrial high-standard projects cooperate with Guangdong Send Electronic; urgent spot mixed orders choose AITM Power; cost-effective consumer wholesale selects Shenzhen Zhide Cable; private brand customized production partners with Ningbo FPIC Electronics. These verified suppliers guarantee stable supply, consistent quality and comprehensive after-sales services for all SB50, SB120, SB175 and SB350 connector procurement demands.
