Description

Choose THOR-602030 when the project can accept 6mm nominal cell thickness but needs 300mAh within a compact 20 × 30mm footprint. For the same 20 × 30mm footprint, THOR-502030↗ reduces nominal thickness to 5mm but provides 250mAh, while THOR-702030↗ increases thickness to 7mm for 400mAh. If the enclosure must stay at 6mm thickness but can use additional length, THOR-602035↗ provides 400mAh in a 6 × 20 × 35mm format. If length must be reduced instead, THOR-602025↗ provides 200mAh in 6 × 20 × 25mm.

The 6 × 20 × 30mm value describes the bare pouch cell. With the current PCM configuration, the battery length is approximately 32mm before allowing for the connector mating area and lead-wire bend radius. In compact keyring electronics, those extra millimeters can determine whether the assembly fits, so enclosure design should account for PCM position, wire exit direction, PH2.0 connector body and cable routing rather than relying only on the bare-cell dimensions.

At 3.7V nominal, 300mAh corresponds to 1.11Wh. Real operating time depends on processor activity, Bluetooth duty cycle, standby current, sensor or AI-processing load, regulator efficiency and cutoff voltage. For the final device, continuous and peak current, PCM behavior, wire length and connector capability should be validated together rather than inferred from capacity alone.

THOR-602030 Engineering & Fit Questions

What is the actual size of THOR-602030 with PCM and connector?

The nominal bare-cell size is 6 × 20 × 30mm. Adding a PCM board and PH2.0 connector typically increases the overall length by 2 to 3mm, giving a finished envelope of approximately 6 × 20 × 32 to 33mm. The exact finished dimensions depend on PCM placement, wire routing and connector orientation, so enclosure design should be confirmed against the approved production-intent drawing.

How does THOR-602030 compare to THOR-502030, THOR-702030 and THOR-602035?

THOR-502030↗ (5mm, 250mAh) is thinner but lower capacity. THOR-602030 (6mm, 300mAh) is the mid-range option when an extra millimetre of thickness is available. THOR-702030↗ (7mm, 400mAh) provides higher capacity at the cost of additional thickness. THOR-602035↗ (6mm, 400mAh) shares the same 6mm thickness but uses a longer 35mm body for 100mAh more capacity. Choose based on your available cavity depth and length constraints.

Is THOR-602030 suitable for Bluetooth and BLE devices?

Yes. With 300mAh at a standard 1C maximum discharge (300mA), THOR-602030 is well matched to the low-to-moderate continuous drain of Bluetooth Classic and BLE applications such as keyring devices, smart tags and compact connected accessories. Many BLE peripherals draw 10 to 30mA average, so a 300mAh cell can deliver multiple days of active use between charges depending on duty cycle and sleep-mode efficiency.

Can I get THOR-602030 without a connector?

Yes. THOR-602030 is available as a bare cell for direct soldering or custom integration, or with pre-assembled lead wires at your specified gauge and length. Standard connector options include PH2.0 with 50mm wires. Wire gauge, lead length, termination style and connector type can all be adjusted for production orders. Contact THOR engineering to discuss your specific wiring requirements.

THOR-602030 3.7V 300mAh LiPo Battery – 6×20×30mm

THOR-602030 is a 1S 3.7V 300mAh lithium polymer battery built around a nominal 6 × 20 × 30mm bare pouch cell, providing 1.11Wh in a compact 20 × 30mm footprint. A current OEM configuration uses PCM protection, approximately 50mm lead wires and a PH2.0 connector for compact Bluetooth keyring electronics. The PCM-equipped battery envelope is approximately 6 × 20 × 32mm; final fit still depends on connector position, wire exit and cable routing.
