Strict Charging Protocols: To maintain optimal cell chemistry, exclusively utilize a dedicated lithium-ion balancing charger calibrated for a 16.8V maximum output. Deploying incompatible, non-balancing, or substandard chargers will compromise the battery's internal structure and void warranty protections.
Operational Prohibitions: Never short-circuit the output terminals. The battery must be protected from severe mechanical impacts, structural punctures, and direct exposure to open flames. Strictly avoid initiating charge or discharge cycles in environments exceeding 60°C or falling below -20°C to prevent irreversible capacity loss.
Secure Installation Guidelines: During device integration, verify that all wires and custom terminals (e.g., XT60) are firmly seated to prevent electrical arcing or intermittent power drops. The pack must be mechanically anchored within the equipment housing to withstand operational vibrations and prevent accidental detachment.
Long-Term Storage & Maintenance: If the equipment will remain inactive for extended periods, discharge or charge the battery to approximately 50% capacity. Store the unit in a climate-controlled, dry environment away from direct sunlight. To preserve the cell's active materials, perform a routine check and partial recharge every three months.
Responsible End-of-Life Disposal: As a high-density energy storage component, this battery must not be discarded in standard waste streams. Upon reaching the end of its functional lifespan, it must be surrendered to certified electronic recycling facilities in strict adherence to local and international environmental regulations.
A: Absolutely not. This advanced lithium-ion pack features a full-charge voltage threshold of 16.8V. It requires a specialized balance charger explicitly designed for 14.8V (4-series) lithium-ion configurations. Utilizing a standard 12V or incompatible charger will result in severe undercharging, potential damage to the internal BMS, and significant safety hazards.
A: We strictly adhere to nominal (minimum) capacity reporting. Following our rigorous 100% factory aging and capacity testing, the actual deliverable capacity of our dispatched units typically exceeds the 6400mAh baseline under standard testing parameters. This guarantees that your portable ultrasound or hematoma devices receive the exact, uninterrupted runtime expected for critical procedures.
A: The integrated industrial-grade BMS acts as the intelligent safety core of the power module. It continuously scans individual cell voltages and overall circuit currents. Should it detect anomalies such as overcharging, deep over-discharging, thermal spikes, or short circuits, the BMS instantly severs the electrical connection. This rapid response protects your high-value medical electronics from irreversible electrical surges.
