Cylindrical lithium-ion packs for commuter, cargo, and performance eBikes.
Custom 18650/21700 battery packs with scalable production and stable cell supply options (e.g., Samsung, LG, EVE). We support pack structure, BMS tuning, and export documents for international shipping.
UAV / Drone Battery Packs
Industrial UAV battery packs for endurance and mission stability.
Focused on voltage stability, power delivery, and energy density for industrial drone systems. Note: we do not supply LiPo (pouch) drone batteries—our UAV solutions are based on cylindrical lithium-ion packs for specific projects and logistics requirements.
Why Choose Us
Engineering-Led Packs. Built for Scalable Production.
Custom battery packs are not “one-size-fits-all.” We start with requirement clarity, then validate step by step—so your pack is safe, consistent, and ready to scale under ISO9001-controlled manufacturing.

common Questions
Frequently Asked Questions About Custom Battery Pack Manufacturing
What information do you need to quote a custom battery pack?
We typically need your target application, voltage, capacity (Ah/Wh), peak/continuous current, size limits, connector requirements, and expected duty cycle. If you already have drawings or a reference pack, share them. The more complete the requirements, the faster we can give an accurate quotation and timeline.
What is your MOQ for custom battery packs?
MOQ depends on the pack structure, cell type, and customization level. Many projects start with prototypes and pilot batches before moving to volume production. Tell us your annual demand and launch schedule, and we will propose a practical MOQ for each stage.
What is the typical lead time from prototype to mass production?
Prototype lead time is usually driven by cell availability, mechanical parts, and BMS configuration. After prototype approval, pilot builds help lock the process before mass production. We will provide a milestone plan so you can track progress from design review to shipment.
Can you support OEM/ODM and brand confidentiality?
Yes. We support OEM/ODM programs and can work under NDA when required. For branded projects, we can align labels, wiring, connectors, and packaging to your product standard. We focus on delivering repeatable quality under your brand requirements.
How do you handle quality consistency across batches?
We control key steps through defined QC checkpoints, traceability records, and process discipline under ISO9001 practices. For critical parameters, we align acceptance criteria with your engineering team before mass production. This helps keep performance consistent from batch to batch.
What applications do you specialize in?
We focus on battery packs for AGVs/AMRs, robotics, eBikes, golf carts, medical devices, and industrial UAV systems. Our solutions are built around cylindrical lithium-ion (18650/21700), LiFePO4, and project-based sodium-ion modules. If you share your use case, we can recommend the best platform.
What cell formats and chemistries do you offer?
We build packs using cylindrical lithium-ion cells (18650/21700), LiFePO4, and project-based sodium-ion solutions. We do not supply LiPo (pouch), solid-state, or lead-acid batteries. Cell brands can be selected based on performance targets and supply stability.
Can you integrate BMS communication like CAN or RS485?
Yes. We can support BMS communication options based on your system needs, such as CAN or RS485, depending on the project platform. We also provide key data outputs like SOC, voltage, current, and fault status for diagnostics and control integration.
What tests can be done for custom battery packs?
Testing is usually planned by project stage: sample verification, pilot validation, and production QC. Custom packs often cannot justify every test upfront due to cost and timing, so we propose a validation roadmap based on the risk profile. You can choose a test package that matches your market and application requirements.
Do you provide compliance and shipping documents?
Yes. We can support common documentation such as UN38.3-related reports (when applicable), MSDS, and packing guidance for lithium battery transport. Requirements vary by market and shipment mode, so we confirm the exact documents needed before delivery planning.
How do you ensure safety for high-power applications?
Safety is managed through cell selection, pack structure, thermal considerations, protective hardware, and BMS protection logic. We review peak current events and duty cycles to define safety margins. The goal is stable performance without unexpected cutoffs in real operating conditions.
Do you offer battery replacements for lead-acid systems?
We do not supply lead-acid batteries. For many systems, we can provide lithium upgrade packs (LiFePO4 or cylindrical lithium-ion) with matched BMS and charging strategy. Share your original voltage and charger/controller details, and we will evaluate compatibility.
