2000w 6 Evf 38 Ebike Graphene Battery 12v38ah 60v 72v
PRODUCT ADVANTAGE
Low Self-Discharge for Uninterrupted Use
With an ultra-low self-discharge rate of only 3% power loss per month:
- Even after 2 days of inactivity on weekends, the battery still retains over 94% of its power.
- Users can easily handle Monday commutes without additional recharging.
Maintenance-Free Solution for Hassle-Free Use
The battery adopts a maintenance-free design via sealed valve-regulated technology, which:
- Eliminates the hassle of regular electrolyte checks required for traditional lead-acid batteries;
- Combines with a fully sealed shell to effectively prevent acid leakage.
This makes it particularly suitable for individual users and small-to-medium repair shops that lack professional maintenance conditions.
Structural Design: Reinforced Shock Resistance & Stable Power Output
The 6-DZM-12 battery integrates reinforced shock-absorbing brackets and a high-toughness shell, successfully passing the ISO 16750-3 vibration test standard. Key test results:
- In a 2-hour high-frequency vibration test (simulating real vehicle operation, with an amplitude of 5mm), the retention rate of connection stability between electrode plates and the shell reaches 98%.
This ensures that even after long-term use, the battery maintains a low internal resistance of less than 15mΩ, guaranteeing the stability and durability of power output during rides.
