2. Physical & Safety Features
Prismatic Pouch Design: Built in a slim, rectangular polymer pouch with approximate dimensions of 6.5 × 40 × 60 mm, optimized for integration into compact, high-performance devices such as portable Bluetooth speakers, mini drones, handheld gaming controllers, and professional-grade voice recorders.
Lightweight Construction: Weighs approximately ~68g, offering a favorable power-to-weight ratio for portable electronics requiring elevated voltage without bulk.
Flame-Retardant Enclosure: Utilizes UL-94V0-rated polymer casing to suppress thermal propagation and meet international safety standards for consumer electronics.
Overcharge protection (cut-off at 8.45V ±0.05V, i.e., 4.225V per cell)
Over-discharge protection (triggered below 6.0V, i.e., 3.0V per cell)
Short-circuit detection (<1ms response time)
Overcurrent limit (supports up to 1C continuous discharge = 1.95A)
Thermal shutdown at 60°C (discharge) and 45°C (charge) per cell
2S Series Configuration: Two 3.7V, 1950mAh cells connected in series to deliver 7.4V nominal voltage, enabling direct compatibility with 7.4V-rated systems without external boost converters.
DC Terminal Design: “DC” indicates a 2-pin direct solder pad or JST-XH-style DC connector, facilitating secure, low-resistance connections ideal for OEM integration in fixed-mount or semi-permanent applications.
3. Charging & Maintenance Guidelines
Recommended Charging Method: Use a dedicated 2S Li-Po CC/CV charger set to 8.4V ±0.05V (4.2V per cell). Optimal charge current: 0.5C (975mA) for maximum cycle life; maximum allowable charge current: 1C (1.95A) for fast charging.
Balancing Requirement: Critical — must be charged using a balanced charger to ensure both cells remain within ±0.05V of each other. Unbalanced charging risks overcharging one cell, leading to swelling or failure.
Charging Environment: Charge only in dry, ventilated areas within 0°C to 45°C. Avoid charging on flammable surfaces or in enclosed spaces.
Discharge Management: Never discharge below 6.0V (3.0V per cell). Devices must include low-voltage cutoff to prevent irreversible cell damage.
Storage Protocol:
For short-term (<1 month): Store at 40–80% SoC (6.8–7.8V).
For long-term (>1 month): Store at ~50% SoC (7.4V) in a cool, dry location (15–25°C).
Recharge every 3 months if unused to prevent deep discharge and cell degradation.
Handling Precautions: Avoid exposure to water, metal contact, or mechanical stress. Do not attempt to disassemble, solder directly to cell tabs, or modify the PCM.
