Description

THOR-802540 provides 600mAh in a compact 8 × 25 × 40mm bare-cell envelope. THOR-702535 is 1mm thinner and 5mm shorter at the same capacity, while THOR-502545 reduces thickness to 5mm but requires 5mm more length. THOR-802540 is the compact rectangular choice when 40mm length is useful and an 8mm-deep cavity is available.

The 8 × 25 × 40mm value is the nominal bare-cell envelope. PCM placement, insulation, connector body, lead exit and wire bend radius can increase the protected-pack dimensions. Confirm the production-intent drawing and sample fit before tooling.

At 3.7V nominal and 600mAh, THOR-802540 stores 2.22Wh. Runtime depends on the real load profile, regulator efficiency, cutoff voltage, duty cycle, temperature and aging. Capacity and geometry do not confirm pulse or continuous-current performance.

THOR-802540 Engineering & Fit Questions

How does THOR-802540 compare with thinner 600mAh alternatives?
THOR-702535↗ reduces nominal thickness to 7mm and length to 35mm at the same capacity. THOR-502545↗ is thinner again at 5mm but requires a 25 × 45mm footprint. THOR-802540 uses 8mm depth to keep length at 40mm.
Are 8 × 25 × 40mm the finished battery dimensions?
No. They are nominal bare-cell dimensions. The protected assembly can be larger because of PCM placement, insulation, connector body, lead exit and wire routing.
What electrical data is needed before approving THOR-802540?
Confirm standby and active load, pulse magnitude and duration, regulator efficiency, cutoff voltage, charge method, temperature and target runtime. Validate the final PCM, wire and connector with the actual electronics.

3.7V 600mAh Lithium Polymer (LiPo) Battery with Connector | THOR-802540

THOR-802540 is a 3.7V 600mAh LiPo pouch cell with 2.22Wh nominal energy and an 8 × 25 × 40mm bare-cell envelope. Its compact rectangular footprint trades greater depth for shorter length than several thinner 600mAh alternatives. Final pack dimensions and load suitability depend on the selected protection and harness configuration.
