🧠 Built for Safety & Efficiency

Each cell and series is individually tested before assembly.
The integrated Battery Management System (BMS) ensures:

• Overcharge / Over-discharge protection

• Cell balancing

• Thermal stability under heavy load

Solid copper and nickel busbars are precision spot-welded to each cell for maximum conductivity and reliability. This overbuilt design means smoother power delivery, cooler operation, and longer battery life.

⚠️ Safety Warning

Lithium-ion batteries are powerful energy systems and must be handled with care.
Always charge using the proper lithium-ion charger.

Do Not:

• Short-circuit or puncture the pack

• Modify connectors or wiring

• Leave charging unattended

• Use if wet or physically damaged

Charge in a fire-safe location (e.g., metal enclosure or fireproof box).
