why choose us
As a professional lithium battery supplier, Greatech provide battery solutions to customers worldwide.
Vertically Integrated Manufacturing
We control the entire production chain-from cell assembly and BMS programming to pack integration and final testing. This eliminates third-party markups, ensures full traceability of every component, and allows us to customize specifications (voltage, capacity, case dimensions, communication protocols) without outsourcing delays.
Rigorous In-House Quality Control
Our on-site laboratory performs IEC 62619, UN38.3, and UL 1973 compliance testing, ensuring each unit meets global safety and performance standards before it leaves the factory.
Scalable & Responsive Production
With automated SMT lines for BMS boards and modular pack assembly stations, we can adjust output from **1,000 to 3,000 units daily** based on order volume. Whether you need a pilot batch of 50 units for field testing or a 10,000-unit annual contract, our flexible manufacturing system scales without compromising lead times or quality consistency.
Direct Engineering & After-Sales Support
Our factory-based technical team works directly with your engineers during the design phase, offering DFM (Design for Manufacturability) feedback and rapid prototyping. Post-delivery, we provide direct warranty handling, firmware updates, and troubleshooting-no middlemen, no communication gaps, just fast, expert resolution from the people who built your batteries.
Versatile & Powerful
Ideal for RVs, marine applications, solar off-grid systems, and backup power, this maintenance-free battery operates reliably across a wide temperature range with zero memory effect.

FAQ
What is your minimum order quantity (MOQ)?
For customized specifications (unique case sizes, proprietary BMS firmware, or branded labeling), the MOQ typically starts at 200 units. Sample orders of 1–5 units are available for quality evaluation at a premium unit price.
What is your typical lead time from order to shipment?
Standard lead time is 15–20 days for in-stock configurations. For bulk orders exceeding 5,000 units or customized builds requiring new cell procurement or mold fabrication, lead time extends to 25–35 days. We maintain buffer stock of core components to prevent delays, and our production planning team provides weekly progress updates once your order enters the schedule.
Can you customize the battery specifications for our application?
Yes. Our engineering team supports full OEM/ODM customization including:
- Voltage and capacity configurations (12V/24V/48V, 50Ah–300Ah)
- Physical dimensions and terminal placements
- BMS parameters (charge/discharge limits, communication protocols: CAN, RS485, Bluetooth)
- Branding, labeling, and packaging design
Custom projects typically require 2–3 weeks for prototype development and validation before mass production.
What quality certifications do your batteries carry?
All batteries are manufactured under ISO 9001:2015 quality management systems and carry UN38.3, MSDS, and CE certifications. Upon request, we can facilitate additional testing and certification (UL 1973, IEC 62619, RoHS, REACH) through accredited third-party laboratories, with certification timelines factored into project schedules.
How do you handle warranty claims and after-sales support?
We maintain detailed production records for every unit, enabling rapid root-cause analysis. For confirmed defects, we offer replacement shipment or repair return within 10 business days. Our engineering team also provides lifetime technical consultation for integration and troubleshooting.
