Connector, NTC and Protection Circuit
The specified pack uses three UL3302 30AWG wires and a JST SHR-03V-S-B connector. Pin 1 is black P−, pin 2 is white 10kΩ NTC, and pin 3 is red P+. The specified thermistor is 10kΩ ±1%, B3435 ±1%. The product photograph shows a two-wire sample; select and approve the required wiring version before ordering.
| Protection function | Specified value |
|---|---|
| Protection IC / MOSFET | S8261DAI-M6T1U / dp8205 |
| Overcharge detection | 4.260–4.300V; typical 4.280V |
| Over-discharge detection | 2.950–3.050V; typical 3.000V |
| Discharge over-current detection | 2.5–4.5A; typical 3.5A |
| PCB resistance | Typical 45mΩ; maximum 60mΩ |
| Operating static current | Typical 5μA; maximum 8μA |

Protection thresholds are fault limits, not permissible continuous load ratings. Keep the design within the cell current limits.
Temperature and Charging Design
Cell charging is specified from 0 to 60°C and discharge from −20 to 80°C. Do not charge below 0°C or treat the 80°C discharge ceiling as a long-term storage condition. Evaluate cell temperature, enclosure heat, NTC response and the ratings of the connector and protection components for the actual installation.
Cycle Life and Capacity Criteria
The cycle-life specification is at least 600 cycles using 0.2C CC-CV charging to 4.2V with a 0.02C termination current, followed by 0.2C discharge to 3.0V. The endpoint is 80% of rated capacity. This is a specified acceptance criterion; no measured cycle curve is included in this product package.
| Characteristic | Specified acceptance criterion |
|---|---|
| 0.2C discharge | Capacity not less than nominal capacity |
| 1C discharge | Capacity not less than 90% of nominal capacity |
| 28-day storage at 20±5°C after charge | Discharge capacity not less than 85% of initial capacity |
Application Fit and Assembly Comparison
Potential integration projects include GPS asset trackers, wireless environmental sensors, portable data loggers, low-power barcode scanners, rechargeable door sensors, compact LED inspection lights, wireless audio receivers and handheld measuring instruments. The 850mAh pouch format suits devices designed around a 3.7V single-cell supply; confirm enclosure clearance, average consumption and startup peaks before selection. VTCBATT offers connector matching, lead-length selection, NTC configuration, protection-circuit review and labeling options for equipment manufacturers, distributors and brand owners seeking OEM battery wholesale and factory-direct batch supply.

Storage and Handling
Recommended storage is 15–35°C at a maximum of 85% RH. For extended storage, maintain 3.6–3.9V and recharge approximately every six months. Keep terminals insulated, prevent puncture and pouch compression, and use an appropriate single-cell lithium-ion charger.
