Powering the Future of Smart Micro-Mobility
As global urban transit shifts toward cleaner alternatives, the demand for highly efficient, lightweight, and durable energy storage has skyrocketed. A robust electric bike requires more than just standard cells; it demands a comprehensive E-bike battery solution engineered to withstand diverse environmental stresses, deliver consistent discharge rates, and communicate seamlessly with the vehicle's powertrain.
VastSea offers customized smart battery packs for E-Bike, micro-mobility, scooters, skateboards, and personal mobility with reliability, well communication, and good design. Our batteries are designed by a team of experienced engineers to fit your electric bicycles. We offer custom ebike battery design including ebike battery case design and unique BMS solution with communication protocol.
By utilizing premium Grade-A cells and proprietary battery management architectures, we ensure that every custom battery pack delivers peak performance, extended cycle life, and absolute safety for end-users worldwide.
State-of-the-Art Battery Technology
Our engineering approach integrates mechanical reliability with cutting-edge electronics to create battery packs that outperform standard market standards.
Custom Smart BMS
Equipped with custom-coded Battery Management Systems (BMS) supporting CANbus, UART, and RS485 communication protocols. Real-time monitoring of SOC, SOH, cell balancing, and multi-stage thermal protection.
Premium Cell Selection
We utilize high-energy-density cylindrical cells (18650/21700) from top-tier global manufacturers. Every single cell undergoes strict capacity, internal resistance, and voltage matching before assembly.
Rugged Enclosure Design
Tailored mechanical designs featuring shock-absorbing internal structures, fire-retardant (UL94-V0) polycarbonate/ABS plastics, or extruded aluminum casings offering up to IP67 ingress protection.
Our Custom Engineering Process
From conceptual design to mass production, we collaborate closely with OEM/ODM clients to deliver optimized power solutions.
Step 1: Requirement Analysis
We gather detailed specifications including motor power rating, space constraints, target range, voltage, expected discharge currents, and desired communication protocols (e.g., CAN, UART).
Step 2: 3D CAD & Thermal Modeling
Our engineers draft the mechanical casing structure, optimizing cell spacing for heat dissipation, structural integrity during vibration, and weight distribution within the E-bike frame.
Step 3: BMS Customization
We program the BMS parameters to match the specific load profiles of your motor controller, integrating smart features like LED indicators, Bluetooth apps, or GPS tracker power lines.
Step 4: Prototyping & Testing
Prototype samples undergo rigid safety assessments, including temperature cycling, vibration testing, drop tests, overcharge/discharge verification, and simulated environmental aging.
