Description

Choose THOR-866898 when the enclosure can accommodate a broad 68 × 98mm battery footprint but needs to keep nominal cell thickness below 9mm while targeting 7200mAh. If a shorter and narrower footprint is more important, THOR-956090↗ provides 6500mAh in a 9.5 × 60 × 90mm format, trading some capacity for a smaller width and length. If more capacity is required and approximately 10mm nominal thickness is acceptable, THOR-1060100↗ provides 8000mAh in a narrower 60 × 100mm footprint. Where thickness is the tighter constraint and additional length is available, THOR-7565121↗ provides 8000mAh in a 7.5 × 65 × 121mm format.

Design the enclosure around the finished battery envelope rather than the 8.6 × 68 × 98mm bare cell alone. The current PCM-equipped drawing is approximately 8.6 × 68 × 100mm, while PCM placement, insulation, lead-wire exit, connector position and harness bend radius can affect the final usable envelope. Allow suitable assembly clearance and normal pouch-cell dimensional change during service, and verify connector mating space and wire routing before freezing the enclosure. Final mechanical approval should be based on the production-intent drawing and validated samples.

At 3.7V nominal, 7200mAh corresponds to 26.64Wh. Actual device runtime depends on the load profile, regulator efficiency, system cutoff voltage, duty cycle, operating conditions and charging strategy. Continuous and peak current, PCM/BMS requirements, connector and wire specifications should therefore be validated for the final device rather than inferred from capacity alone. THOR-866898 can also serve as a cell platform for custom multi-cell battery-pack integration↗. For example, four identical cells arranged as 4S1P correspond theoretically to 14.8V nominal, 7200mAh and 106.56Wh, with 16.8V full-charge voltage; BMS selection, current path, wiring, charging method and final mechanical layout must still be engineered at pack level.

THOR-866898 Engineering & Fit Questions

What are the bare-cell and finished dimensions of THOR-866898?

The nominal bare-cell size is 8.6 × 68 × 98mm. The current PCM-equipped drawing is approximately 8.6 × 68 × 100mm. The finished envelope may vary with PCM placement, insulation, wire exit, connector position and harness routing, so enclosure design should be confirmed against the approved production-intent drawing.

How much enclosure clearance should I allow around THOR-866898?

Do not size the cavity only to the nominal 8.6 × 68 × 98mm bare cell. Allow room for manufacturing tolerance, PCM and lead-wire high points, connector mating, cable bend radius and normal pouch-cell dimensional change during service. Final clearance should be validated with production-intent samples before the enclosure design is frozen.

Can THOR-866898 be used in a 4S1P backup-power battery pack?

Yes, THOR-866898 can be evaluated as the cell platform for a custom 4S1P pack. Four identical 3.7V 7200mAh cells connected in series correspond theoretically to 14.8V nominal, 7200mAh and 106.56Wh, with 16.8V full-charge voltage. The final BMS, current capability, wiring, connector, charging method, balancing strategy and pack dimensions must be engineered for the specific project.

Which THOR model should I compare if 8.6 × 68 × 98mm does not fit?

Compare THOR-956090↗ if a shorter and narrower footprint is preferred, THOR-1060100↗ if higher capacity and a narrower 60mm width are more important, or THOR-7565121↗ if lower thickness is the main constraint and additional length is available. If still more capacity is required and additional thickness is acceptable, THOR-1160100↗ provides 10000mAh in an 11 × 60 × 100mm nominal cell.

THOR-866898 3.7V 7200mAh LiPo Battery – 8.6×68×98mm

THOR-866898 is a 1S 3.7V 7200mAh lithium polymer (LiPo) pouch cell with a nominal 8.6 × 68 × 98mm bare-cell size and 26.64Wh nominal energy. Its broad 68 × 98mm footprint keeps nominal cell thickness below 9mm, making it a practical geometry for high-runtime handheld terminals, industrial handheld controllers and field-electronics designs where enclosure depth is tighter than the available battery footprint. The current PCM-equipped drawing is approximately 8.6 × 68 × 100mm. Final pack dimensions depend on PCM layout, insulation, wire exit, connector position and harness routing.

Typical Applications — THOR-866898

Industrial Handheld Controllers — PrimaryThe 7200mAh capacity and broad 68 × 98mm footprint make THOR-866898 a candidate for high-runtime industrial handheld controllers where sufficient battery area is available but nominal cell depth should remain below 9mm. Confirm the finished-pack envelope, continuous and peak load, connector and wire routing before sample approval.

Handheld Terminals, Portable HMI & Maintenance DevicesTHOR-866898 can suit high-runtime handheld terminals, portable HMI and maintenance devices using displays, communications and control electronics when a wide, relatively flat battery cavity is available. Validate display duty cycle, communications load, cutoff voltage and finished-pack fit for the final device.

Industrial Inspection & Condition-Monitoring EquipmentTHOR-866898 can suit portable inspection and condition-monitoring equipment where extended field runtime and a broad battery footprint are more important than minimum width. Confirm sensor, display, data-logging and wireless loads together with PCM, connector and mechanical integration.

Custom 4S1P Backup Power PacksTHOR-866898 can also be used as the cell platform for custom multi-cell backup-power assemblies where the system requires higher pack voltage and extended backup energy. A 4S1P architecture based on four identical cells is one possible engineering direction, but the final BMS, current path, wiring, connector, charging strategy and mechanical structure must be validated at pack level.
