⚙️ Precision Cell Matching & Durable Assembly
To ensure long cycle life and balanced performance, each cell undergoes strict matching before assembly:
-
Voltage difference: ≤10mV
-
Capacity difference: ≤20mAh
-
Impedance difference: ≤5mΩ
Cells are welded using extra-wide, thick nickel-plated strips to safely support a continuous 60A current—guaranteeing high-load capacity and eliminating the risk of weak welding points.
🔌 Smart Connectors & Charging Support
-
Equipped with DC5521 dust-proof charging plugs
-
High-current Anderson discharge connectors for reliable output
-
Supplied with matching 54.6V 3A (for 48V packs) and 42V 3A (for 36V packs) battery chargers
🔁 Age & Quality Control Process
Before shipment, each battery pack undergoes a full age cycle, include:
-
Complete discharge from 42V/54.6V to cut-off voltage
-
Fullly recharge back to 42V/54.6V
-
Final inspection and load testing to confirm performance
- Discharge to 30%~50% electricity to ensure safety transportation
