Description

THOR-103450 concentrates 2000mAh into a compact 10 × 34 × 50mm bare-cell envelope. THOR-103750 keeps the same capacity, thickness and 50mm length but widens the cell to 37mm. THOR-654065 reduces thickness to 6.5mm at the same capacity but requires a much larger 40 × 65mm footprint. Choose THOR-103450 when compact plan area is more important than minimum thickness.

The verified 10 × 34 × 50mm value is the nominal bare-cell envelope. The current PCM-equipped drawing is approximately 10 × 34 × 52mm. Connector position, insulation, lead exit and wire bend radius still require clearance, so confirm the complete production-intent assembly before enclosure approval.

At 3.7V nominal and 2000mAh, THOR-103450 stores 7.4Wh. Actual runtime depends on load profile, regulator efficiency, cutoff voltage, duty cycle, temperature and aging. Capacity and 10mm depth do not establish high-current capability; validate continuous and peak demand with the intended PCM and harness.

THOR-103450 Engineering & Fit Questions

How does THOR-103450 compare with thinner 2000mAh options?

THOR-103450 uses a compact 10 × 34 × 50mm envelope. THOR-654065↗ reduces thickness to 6.5mm but requires a 40 × 65mm footprint, while THOR-803273↗ uses 8mm thickness and a much longer 32 × 73mm footprint.

Are 10 × 34 × 50mm the finished THOR-103450 dimensions?

No. They are the verified nominal bare-cell dimensions. The current PCM-equipped drawing is approximately 10 × 34 × 52mm, with additional connector and wire-routing clearance still required.

Does 2000mAh confirm runtime or high-current performance?

No. The rating corresponds to 7.4Wh at 3.7V nominal, but runtime depends on the complete load profile, conversion efficiency, cutoff voltage, duty cycle, temperature and aging. Continuous and peak-current capability require separate validation.
