One. Battery Specifications
All products are according to automotive battery standards, using embedded bracket modules to calmly cope with bumpy roads.
1. A+ grade lithium-Ion cells.
2. Using anti-vibration material, Strengthen anti-vibration treatment.
3. Design the battery structure according to aerodynamics to enhance heat dissipation.
4. Does not use any glue, and meets RoHS/CE requirements.
5. ABS + PC and V0 grade flame retardant material.
6. Adopt pure nickel forming sheet welding cell, the advantages are as follows:
1). The welding is stronger.
2). The battery discharge is more uniform.
3). Reduced internal resistance.
4). Reduces soldering defects.
5). Welding is stronger and not easy to fall off.
