III. Working Principle
Uses valve-regulated sealed (VRLA) technology, factory-filled with electrolyte, sealed structure, no need to add liquid during use. Internally a high-strength ABS housing with VRLA structure provides strong vibration resistance; high-strength copper-insert terminals offer excellent high-current conductivity for frequent start-stop and high-power applications.
IV. Applications
The electric bicycle battery series suits the following electric-vehicle scenarios:
• Electric bicycles / electric motorcycles
• Electric scooters / self-balancing scooters
• Electric wheelchairs
Application fields listed in the product specification: electric bicycles, electric motorcycles, electric scooters, electric wheelchairs.
V. Performance Advantages
This model offers the following performance features:
High-current discharge: high-strength copper-insert terminals provide good high-current conductivity for frequent starting and acceleration.
Deep-cycle durability: special plate and grid design optimized for deep-cycle use.
Maintenance-free: VRLA sealed structure, no liquid topping-up.
High mechanical strength: ABS housing with VRLA structure resists vibration and shock.
Strong environmental adaptability: stable operation over a wide temperature range.
Safety-valve protection: each cell has a safety valve that opens automatically to release pressure when abnormal.
Note: Data note: quantitative indicators such as the cycle-durability count (per GB/T 22199.1-2025 clause 4.12, >= 380 cycles) are subject to Chisen's latest official datasheet.
VI. Use and Maintenance
As a maintenance-free VRLA lead-acid battery, follow these points in daily use:
Appearance and terminals: periodically check the case for deformation/leakage, terminal tightness and correct polarity.
Cleaning and heat dissipation: keep the surface dry and clean, avoid direct sunlight and high-temperature storage.
Charging: use Chisen-recommended smart three-stage charging (constant current -> constant voltage -> float), float voltage reference 14.7V (2.45V/cell x 6), see the included datasheet.
End of discharge: avoid over-discharge; recharge periodically when stored long-term.
Note: The current specification does not separately list charging current, temperature-compensation coefficient or cut-off voltage for this model; please contact Chisen Battery sales for the latest datasheet.
VII. Selection Advice and Market Outlook
When selecting, buyers are advised to focus on the following:
Voltage matching: choose by vehicle system voltage (48V system 4 in series / 60V 5 / 72V 6).
Battery-box size: confirm dimensions fit the box, note weight handling.
Duty cycle: select per the application scenarios in the specification.
Cycle-life requirement: per GB/T 22199.1-2025 clause 4.12, cycle durability shall be no less than >= 380 cycles.
Terminal spec: confirm terminals are compatible with the vehicle harness.
