Core Technical Parameters: Stable and Professional Performance
Performance and compatibility are the foundational standards for e-bike battery replacement. This 48V lithium battery pack adopts standardized industrial design and strict quality testing, with precise parameter settings to adapt to most mainstream modified and original electric bikes on the market. The battery features a nominal voltage of 48V, paired with three optional nominal capacities: 10.4Ah, 12Ah, 12.8Ah, and 14Ah, allowing users to select the appropriate version according to their daily riding mileage and power demands.
Supporting a maximum motor power of 1000W, this battery is fully compatible with 250W, 350W, 500W, 750W, and 1000W motors, covering daily commuter bikes, fat tire e-bikes, mountain e-bikes, electric scooters, and electric tricycles. It adopts a 30A rated discharge current design, which perfectly matches the power output demand of 48V 0-1000W motors, ensuring continuous and stable power supply without power attenuation or stuttering during high-load riding such as climbing hills, accelerating, and long-distance cruising.
In terms of charging standards, the battery is equipped with a 54.6V charge cutoff voltage and a 2A standard charging current, which conforms to the universal charging specification of 48V lithium batteries, effectively avoiding charging abnormalities caused by voltage mismatch. Its dual discharge port design, including a 4-pin discharge port and an XT60 plug, greatly improves compatibility with different e-bike circuit systems and controller setups. With compact dimensions of 396*93*91mm and a net weight of about 3.2kg (package weight 5kg), the battery balances portability and structural stability, avoiding excessive weight that affects riding flexibility and vehicle control.
Premium 18650 Lithium Cell Technology & Tough Build: Durable and Long-Lasting
The core quality of an e-bike battery depends on its internal cells. This replacement battery adopts brand-new high-quality 18650 lithium-ion cells, which are widely recognized in the new energy industry for their high energy density, stable chemical properties, and excellent cycle performance. Compared with traditional lead-acid batteries, 18650 lithium cells have the advantages of lighter weight, smaller volume, stronger shock resistance, and no memory effect, enabling flexible charging and discharging without permanent capacity loss.
One of the most outstanding advantages of this battery is its ultra-long service life, with a cycle life of more than 1000 charge and discharge cycles. Strict QC appearance and functional tests are implemented for every battery before shipment. Each cell undergoes layer-by-layer screening, aging tests, and performance calibration to ensure consistent output of the entire battery pack. In daily use, even with frequent charging and discharging, the battery maintains slow and stable capacity attenuation, effectively reducing battery replacement frequency and lowering long-term travel costs for users. Additionally, the battery features a robust hard casing that provides reliable protection against daily scratches, bumps, drops, and outdoor abrasion, greatly improving overall durability and environmental adaptability.
30A BMS Intelligent 8-in-1 Protection System: All-Round Safety Guard
Safety is the most critical factor for e-bike power batteries, and this product is equipped with a professional 30A BMS (Battery Management System) protection board, the core safety guarantee for stable lithium battery operation. Unlike ordinary e-bike batteries with limited protection functions, this upgraded BMS module supports real-time millisecond-level monitoring of single-cell voltage, overall current, and operating temperature, and automatically cuts off the circuit once abnormal conditions are detected to eliminate potential safety hazards in advance.
The BMS system integrates 8 core safety protection functions: short circuit protection, charge reverse protection, over charge protection, over discharge protection, over voltage protection, over heating protection, over current protection, and over power protection. The overcharge protection function automatically cuts off the charging circuit when the battery reaches full power to prevent electrolyte decomposition and thermal runaway caused by long-term overcharging. The overdischarge protection locks the discharge output when power is exhausted to avoid irreversible damage to battery cells. Short-circuit and over-current protection instantly power off the circuit to prevent burnout and fire risks. Meanwhile, the intelligent temperature control system adapts to a wide working range of 0°C to 45°C for charging and -10°C to 60°C for discharging, ensuring safe and stable operation in extreme cold, high temperature, and complex seasonal environments worldwide.
Furthermore, this battery has passed authoritative global certifications including CE, RoHS, UN38.3, MSDS, ISO9001, and UL-2271, fully complying with North American and European safety and environmental standards, making it safe and legal for daily use and cross-border transportation.
Humanized Design: Easy Installation & Intelligent Power Management
This 48V lithium battery pack is tailor-made for Vivi F26F and H8 electric bikes, while maintaining universal compatibility with most adult electric mountain bikes, hybrid e-bikes, daily commuter e-bikes, fat tire e-bikes, electric tricycles, and modified 48V electric bicycles and scooters on the market. Designed specifically for down tube frame installation, the battery comes with a matched fixed base plate, enabling direct mounting on the bike frame without cutting, drilling, or professional modification. The plug-and-play design allows users to complete battery replacement and installation within minutes without professional tools or technical knowledge.
It is equipped with multiple user-friendly functional designs to optimize daily use experience. A physical power switch marked with "O" for power off and "-" for power on allows users to completely cut off idle power when parking to save electricity and improve riding safety. A built-in anti-theft safety lock firmly fixes the battery on the frame, effectively preventing battery theft during outdoor and street parking. In addition, the one-touch LED power indicator clearly displays 100%, 75%, 50%, and 25% remaining power, enabling real-time checking of battery level and charging status, completely solving the problem of unclear power judgment and sudden roadside power failure.
