72V 45Ah Electric Motorcycle Battery (73.6V Nominal, 45Ah LFP, BMS‑Protected) for OEM & Wholesale
■ This is a 72V electric motorcycle for adults battery built on 73.6V nominal LFP chemistry for high-load e-mobility platforms.
■ It is supplied B2B only for OEM brands, importers, distributors, wholesalers, and fleet/rental operators serving the US and EU.
■ Typical applications include electric motorcycles, dual-motor performance scooters, off-road/racing e-scooters, electric tricycles, heavy-load cargo e-trikes, utility/delivery tricycles, passenger trikes for hilly terrain, and electric go-karts.
Key advantages (B2B / system-focused)
1.73.6V nominal LFP platform: suited to 72V-class powertrains where voltage stability and safety margin are priorities.
2.45Ah standard configuration: simplifies SKU planning for production and aftermarket support.
3.High-power duty cycle design: intended for sustained current demand in off-road, hilly, and cargo scenarios.
4.BMS protected operation: electrical protection logic aligned with traction applications (current peaks, braking events where applicable, temperature boundaries).
5.Customer-designed communication protocol: interface can be defined to match your controller/VCU and diagnostics requirements.
6.OEM integration orientation: configuration work is driven by current draw, thermal constraints, packaging, and service strategy-not consumer feature checklists.

Over 20 Years of Industry Experience
As a national high-tech enterprise, we have been deeply involved in the lithium battery industry for over two decades, committed to creating high-quality power battery products.
Focus on LEV Lithium Batteries
Specializing in 48V/60V/72V electric bicycle, motorcycle, and tricycle batteries, with a focus on lightweight and high-performance design for extended range and durability.
Manufacturing & Innovation
We operate our own smart factory and have developed proprietary LEV-specific heat dissipation structures, providing comprehensive, high-performance solutions.
Customize your Battery Pack
Tailor voltage, capacity, BMS, and casing to your e-scooter, e-bike, or golf cart application.
Grade A cells
100% New Grade-A LFP Cells
We use only genuine, brand-new Grade-A lithium iron phosphate (LFP) cells from top-tier manufacturers-never recycled or B-grade cells. Each cell is strictly screened for consistent capacity, internal resistance, and voltage, ensuring your battery pack delivers reliable performance and extended cycle life from day one.
BMS
Smart 3-Layer Communication BMS
Our intelligent BMS features a 3-layer communication architecture (CAN/RS485/UART) that delivers real-time monitoring, overcharge/discharge protection, temperature management, and cell balancing. Advanced algorithms ensure your battery operates safely and efficiently across all conditions, with data logging and remote diagnostic capabilities for easy fleet management.
SHELLS
Rugged Aluminum Alloy Shell - IPX6 Rated
Our battery packs are housed in high-strength aluminum alloy enclosures, precision-machined for a perfect fit. The IPX6 waterproof rating protects against powerful water jets and heavy rain, while the corrosion-resistant surface treatment ensures durability in harsh environments. The lightweight yet rigid design also provides excellent impact resistance and heat dissipation for optimal cell performance.
Spare Parts
Full-Spec Accessories - Plug & Play Ready
Every battery pack comes complete with the necessary accessories for seamless integration. We provide custom-length output cables with your choice of connectors (Anderson, Amphenol, XT series, or custom), dedicated charging harnesses with proper gauge wiring, and mounting brackets tailored to your installation space. All components are pre-installed and tested before shipping-just mount, plug, and go.
Production process
01 Cell Sorting
Battery cells are accurately matched based on voltage, capacity, and internal resistance to ensure excellent consistency, safety, and long cycle life.
02 Cell Assembly
Matched battery cells are assembled according to the required pack configuration to ensure a stable and reliable battery structure.
03 Automatic Spot Welding
Advanced automatic spot welding equipment provides strong and precise welding connections, improving product reliability and manufacturing efficiency.
04 BMS Installation
A Smart BMS is installed to provide multiple safety protections, including overcharge, over-discharge, overcurrent, short circuit, and temperature protection. CAN communication is available upon request.
05 Wiring Installation
Professional wiring harnesses, connectors, and communication cables are installed and securely connected to ensure stable electrical performance and reliable signal transmission.
06 Insulation Protection
High-quality insulation materials are applied to protect the battery pack from electrical hazards, improve safety, and enhance long-term durability.
07 Battery Pack Assembly
The battery module is assembled into a durable housing with secure mechanical fastening, ensuring reliable protection in various operating environments.
08 Aging Test
Each battery pack undergoes charging and discharging cycle tests to verify stability, performance, and long-term reliability before delivery.
09 Final Quality Inspection
Every finished battery pack is subjected to comprehensive inspections, including voltage, capacity, BMS function, communication, and appearance checks. Only qualified products are approved for shipment.
More Than Storage-It's Quality Assurance.
At Tenz Energy, we don't just build custom batteries-we make sure they stay at peak performance throughout their entire lifecycle.
To help you get the most out of your investment, here are a few simple but essential care tips.
Charging Smart
Always use the charger we recommend. For daily use, we suggest keeping the charge level between 15% and 95%-this small habit can significantly extend your battery's cycle life.
Operating Safe
Your battery performs best within moderate temperatures. Please avoid charging below 0°C and keep it away from fire, water, or prolonged heat exposure.
Storing Right
When not in use for a while, store the battery in a cool, dry, and ventilated space at 30%-80% SOC. A quick health check every two months helps us catch any issues early.
Inspecting Regularly
Before each use, take a moment to check the connectors and casing. If anything feels off-stop, and reach out to us.
