3.7V 3000mAh lithium polymer cells for portable speakers, medical devices, handheld terminals and IoT products. Our 3000mAh range pairs a wide, thin 4 mm panel cell (THOR-407090, 4 × 70 × 90 mm) with compact 12 mm blocks (THOR-123065), so the same capacity can sit flat behind a large display or pack into a deep tool. Compare the finished sizes and request the pouch that fits.

Finished dimensions depend on PCM, insulation, connector and wire-harness configuration and are confirmed on the engineering drawing for the selected model.
Selecting 3000mAh for Displays or Deep Housings
At 3000mAh the split is between a broad thin panel and a compact deep block. Our slimmest is 4 mm but wide (4 × 70 × 90 mm), ideal behind a tablet or monitor display; the thickest is a 12 mm block (12 × 30 × 65 mm) for handhelds and tools where depth is available and area is scarce. Compare each model’s finished thickness, width and length to your usable cavity and account for the PCM and harness on the length. Choosing between 2500mAh, 3000mAh and 4000mAh usually comes down to runtime versus space — send us both and we will recommend.

3000mAh LiPo Battery FAQ
What products use a 3000mAh LiPo battery?
3000mAh is common in portable Bluetooth speakers, medical devices and monitors, handheld terminals, and IoT products that need most of a day or more of runtime. Our range covers both wide thin panels and compact deep blocks.
How thin can a 3000mAh cell be?
4 mm (THOR-407090), but wide at 70 × 90 mm. A thin 3000mAh cell needs a large flat area, so it suits a panel or display rather than a narrow cavity.
Do you have a compact, deep 3000mAh option?
Yes — about 12 × 30 × 65 mm (THOR-123065), which suits handhelds and tools where depth is plentiful and you want a small footprint.
How long will 3000mAh last?
Runtime in hours ≈ 3000 ÷ average mA. A device drawing 300 mA runs about 10 hours; one drawing 150 mA about 20. Peak loads and cut-off voltage shift this — send your profile for an accurate figure.
Should I pick 2500, 3000 or 4000mAh?
It depends on runtime versus space. The three overlap in size, so we recommend choosing by your exact cavity and target hours; send both and we will map them onto the best option.
Can a 3000mAh cell support high continuous current?
Continuous and peak current depend on the cell’s C-rate and the PCM rating. Many 3000mAh models support several amps continuous with higher short peaks. Tell us your currents and we confirm a suitable cell and protection board.
