1. Premium Matching Components – Strict Standardized Configuration
Every component adopts fixed certified models to guarantee batch consistency and stable output:
Grade A INR18650-32B Lithium Cell Nominal voltage 3.6V, typical capacity 3200mAh, guaranteed minimum capacity 3040mAh. High energy density, low self-discharge and no inflated capacity issues to ensure long-lasting power supply.
Custom RYD-01S-152 PCM Protection Board + Precision NTC Sensor Built with Ricoh R5405 professional protection IC; matched NCP15WF104F03RC 10kΩ NTC thermistor with ±1% precision for real-time temperature monitoring. The 364.21.0mm double-layer FR4 tin-spray PCB features main loop resistance ≤65mΩ and ultra-low standby consumption ≤10μA, minimizing power loss during long storage.
Standard JST XH-3P 2.5mm Pitch Connector Equipped with UL3239 24# wires with fixed wiring definition (P1=Black, P2=Yellow, P3=Red). Standard wire length 43±3.5mm with uniform tin immersion, easy for plug-and-play assembly into customer devices.
2. Core Electrical Parameters – Balanced Performance for Diverse Scenarios
All electrical indicators are verified under standard 25±2℃ test environment, fully compliant with international portable power standards:
Voltage Specifications: Charge cut-off voltage 4.2V, discharge cut-off voltage 2.8V. Factory shipment voltage controlled within 3.55–3.65V with SOC ≤30% to avoid over-discharge during long-distance logistics.
Current Limits: Max charging current 0.5C (1.5A); max continuous discharge current 1C (3.2A); overcurrent protection trigger point 9±1.5A, supporting stable medium-low power output.
Standard Charge & Discharge Protocol: 0.2C constant current charging to 4.2V, then constant voltage charging until current drops below 0.02C. After full charge and 1-hour rest, 0.2C constant discharge to 2.8V for capacity testing.
Low Impedance & Lightweight Size: Whole pack internal impedance <200mΩ to reduce heat generation; total weight approx 60g, overall dimension 22.318.75±0.3566.6±0.5mm for easy built-in installation in compact devices.
Ultra-Wide Working Temperature Range Charging: 10℃~45℃; Discharging: -20℃~60℃. Maintains steady power output in freezing outdoor or high-temperature indoor environments.
Tiered Storage Temperature Rules Storage ≤1 month: -20~45℃; ≤3 months: -10~30℃; ≤1 year: 0~30℃. Optimal long-term storage environment 10–25℃ with 40%–60% SOC to cut self-discharge loss.
3. 6-Fold Integrated Safety Protection System
Our customized PCM eliminates mainstream lithium battery safety risks with precise delay control to prevent false protection:
Overcharge Protection: Trigger at 4.280±0.025V with 0.96–1.4s delay, recover at 4.180±0.050V
Over-Discharge Protection: Activate at 2.800±0.080V with 20±15ms delay, resume at 2.900±0.100V
Overcurrent Protection: Cut off output at 9±1.5A within 9±2ms, auto-recover after load removal
External Short Circuit Protection: Instant power cut once short circuit detected, restore after short trouble eliminated
NTC Real-Time Temperature Monitoring: Cooperate with host equipment to cut power under abnormal high temperature, effectively prevent thermal runaway
Micro Standby Power Consumption: Static working current ≤10μA, no rapid power drain during long idle storage
4. Outstanding Cycle & Storage Reliability – Lower Long-Term Use Cost
Every batch undergoes complete aging and reliability testing to extend service life:
≥300 Standard Charge-Discharge Cycles After 300 cycles under 25℃ room temperature, discharge capacity remains above 80% of rated capacity, outperforming ordinary unprotected battery packs and reducing after-sales replacement frequency.
Excellent 28-Day Capacity Retention Fully charged batteries stored at 23±2℃ for 28 days can sustain ≥255 minutes of 0.2C discharge, featuring ultra-low self-discharge rate.
Stable 12-Month Long-Term Storage Performance Batteries stored at 40%–65% SOC under 20±5℃ for 12 months still support ≥240 minutes of discharge after full recharge, without permanent capacity attenuation for inventory stock.
Passed Strict Mechanical Reliability Tests
Vibration Test: X/Y/Z three-axis vibration for 30 minutes each; no damage to circuits or performance degradation
Drop Test: 6 random-direction free falls from 1m height onto wooden boards; zero fire, zero explosion and intact structure
