The ASOL 18650-3P uses three cylindrical Li-ion cells in a 3-parallel (3P) configuration to deliver 7800mAh at a stable 3.7V. This pack format is suitable for thermal printers, industrial handhelds, medical monitors and backup systems requiring a rechargeable battery pack.
For B2B projects, connector, wire, protection-circuit, packaging and labeling requirements can be evaluated according to the finished device and project specification.
Key Highlights
- 7800mAh / 28.86Wh — rated capacity and energy; actual runtime depends on the device load profile and operating conditions.
- 3P Parallel Configuration — three cylindrical cells connected in parallel.
- 3.7V Nominal Output — confirm charging method, system voltage compatibility and load requirements during project review.
- Pack Integration — assess enclosure space, mounting method and wire routing against the finished pack dimensions.
- Protection Options — protection circuit options are available depending on the required battery configuration.
- Project Review — connector, wire, packaging and labeling requirements can be evaluated according to the project specification.
Why This Battery?
| Your Problem | ASOL18650-3P Solution |
|---|---|
| Thermal printer has a defined duty cycle and runtime requirement? | 7800mAh / 28.86Wh rated capacity; actual printer runtime depends on duty cycle, temperature and load. |
| Industrial PDA or barcode scanner has a defined duty cycle and runtime requirement? | 3P parallel configuration should be evaluated against the scanner load profile, charging method and required runtime. |
| Portable medical equipment requires a project-specific battery review? | Protection and pack configuration should be reviewed against the device safety, performance and validation requirements. |
| Mini UPS battery self-discharges and is dead when a power outage finally hits? | Standby use — storage and standby performance should be validated for the selected cell, pack design and operating conditions |
| Generic battery pack doesn’t fit your device’s connector or power requirements? | Project configuration review — connector, wire, protection-circuit and label requirements are confirmed against the finished device. |
