In commercial electric bike fleets and rental services across major French cities like Paris, Lyon, and Marseille, high-frequency usage and deep discharge cycles are standard daily operating conditions. For fleet operators, rental platforms, and OEM/ODM buyers, premature capacity loss and frequent battery replacements are the primary drivers inflation Total Cost of Ownership (TCO) and maintenance expenses.

To minimize long-term maintenance overheads, procurement teams evaluating Hailong lithium battery packs must focus on key engineering parameters, such as Depth of Discharge (DOD) cycle life, cell consistency, and BMS protective controls.

In commercial fleet environments, riders routinely deplete battery capacity down to low percentages before recharging. Standard battery cycle ratings based on shallow discharge fail to reflect true durability under commercial stress.

• Degradation Control Under Deep Discharge: Under continuous testing at 85% Depth of Discharge (DOD), the battery pack retains an 800–1000 charge/discharge cycle lifespan. This ensures consistent power output over years of frequent deep-discharge riding, extending replacement intervals.

• Cutting Maintenance and Replacement TCO: Extended cycle life directly minimizes fleet downtime caused by battery degradation, enabling French B2B operators to significantly reduce hardware replacement and servicing expenses.

In addition to cycle durability, continuous system reliability under demanding daily operations relies on specific technical specifications:

Engineered with brand-new Grade-A 18650 or 21700 cells, the system guarantees tight voltage and internal resistance consistency across all cells. Available in capacity options from 10Ah to 35Ah, Grade-A cells mitigate internal heat accumulation during rapid power demands, slowing chemical aging.

To accommodate varied motor systems within a fleet, the battery features a continuous-current smart BMS rated at 20A or 30A. The 20A BMS pairs with 500W motors, while the 30A BMS supports 750W–1000W motors, preventing over-current damage on steep climbs or heavy loads.

Featuring standard Hailong downtube dimensions of 368 × 95 × 138 mm and a total weight of 5–8 kg, the standardized quick-release casing facilitates fast battery swaps and centralized charging station operations for field technicians.

For French fleet managers and volume purchasers, the following selection steps are recommended:

1. BMS and Motor Power Alignment: Match the BMS rating to your fleet motor specifications (specify 20A BMS for 500W motors; select 30A BMS for 750W–1000W motors).

2. Capacity and Range Planning: Select appropriate capacity options between 10Ah and 35Ah based on daily distance requirements.

3. Charger Integration: Pair with 2A–5A smart chargers to optimize turnaround times while maintaining cell health.
