Frequently Asked Questions
What is the expected operational lifespan of an industrial e-bike battery pack?
Built with Grade-A cylindrical cells and a matched smart BMS, industrial e-bike packs typically deliver 800 to 1,200 full charge-discharge cycles before capacity drops to 80% of original rating, translating to 3 to 5 years of daily commercial fleet service.
How to choose between integrated down-tube, Hailong, and rack-mount form factors?
Hailong form factors provide convenient key-locked quick-release mounting for standardized urban fleets. Custom sheet metal or IP67 aluminum enclosures are selected for heavy-duty cargo tricycles requiring extreme vibration resistance and water sealing.
Can low winter temperatures permanently damage e-bike battery capacity?
Sub-zero temperatures temporarily reduce discharge runtime due to electrolyte viscosity, but capacity fully recovers once warmed. However, charging below 0°C without active BMS pre-heating causes permanent lithium dendrite damage and must be strictly prevented.
