A UAV Battery Specialist,
Not a Generic Supplier
Founded in 2015 and headquartered in Shenzhen, China, UMAX Power focuses exclusively on designing and manufacturing custom lithium battery packs for drones, UAVs, and high-performance aerial platforms. Our factory spans 2,000 m² with 4 dedicated production lines and a team of 50+ specialists.
Unlike general-purpose battery suppliers, every decision we make -- from cell chemistry to BMS architecture -- is informed by the unique demands of UAV applications: energy density, discharge rate, weight, thermal performance, and mechanical integration.
Engineering Advantages That
Deliver Real Flight Results
Precision Cell Selection
We evaluate each project actual operating conditions -- voltage, discharge current, temperature, weight, and cycle life -- then select cells that match, not just the cheapest option.
High-Rate Discharge Packs
Optimized nickel strip thickness, cable gauge, and connector selection deliver stable high-current output for heavy-lift UAVs without excessive voltage drop.
Advanced BMS Integration
Custom BMS matched to each pack -- over-charge, over-discharge, short-circuit, thermal protection, cell balancing, plus optional SMBus/CAN/RS485 communication.
Semi-Solid State Technology
Our semi-solid state battery platform achieves up to ~500 Wh/kg -- enabling longer flight times without increasing battery weight for demanding aerial applications.
Cell Matching & Consistency
Every cell is sorted by capacity, internal resistance, and voltage before assembly. Consistent cell matching reduces pack imbalance, extends cycle life, and improves safety.
Complete OEM/ODM Service
From prototype development to mass production -- custom housing, labels, connectors, packaging, UN38.3 documentation, and export shipping coordination in one factory.
From Requirements
to Production -- Your Path
You don't need to know every battery parameter before contacting us. Share your UAV specs and we'll engineer the right solution.
Share Requirements
Tell us your UAV voltage, power, application, weight limits, and flight time goals. No battery spec knowledge required.
Engineering Review
Our team evaluates your platform -- motor specs, ESC requirements, payload, and operating environment -- to determine the optimal battery architecture.
Spec Confirmation
We present a tailored specification: cell type, energy density platform, S/P configuration, BMS, dimensions, weight, and connector -- then await your approval.
Sample Production
Sample batteries are built and delivered within 7-14 days for your flight testing, bench testing, and integration validation.
Optimize & Approve
Based on your test feedback, we refine specifications if needed. Once approved, we lock the production design.
Mass Production
Stable batch production with full QC documentation -- test reports, MSDS, UN38.3, and export shipping coordination included.
