3.7V 2500mAh lithium polymer cells for tablets, portable speakers, medical monitors, power banks and higher-drain handhelds. Our 2500mAh range is broad on both thickness (a slim 3.6 mm option up to sturdier 16 mm builds) and footprint, so the same capacity can be a thin panel behind a display or a thick brick in a rugged tool. Compare finished sizes and request the pouch that fits.
2500mAh LiPo Battery Models
All available 3.7V 2500mAh models, sorted thickness-first. The range is wide — from a 3.6 mm slim cell to 16 mm thick builds — so you can match a flat cavity or a deep one. Use the size tool or sort by any axis.

Finished dimensions depend on PCM, insulation, connector and wire-harness configuration and are confirmed on the engineering drawing for the selected model.
Selecting 2500mAh for Displays, Power Banks or Rugged Tools
At 2500mAh the trade-offs widen: our pouches run from a 3.6 mm slim cell that tucks behind a tablet or monitor display, up to 16 mm-thick blocks for power banks and rugged handhelds where depth is plentiful. That wide thickness range is the key decision — a thin cell needs more area, a thick one needs depth. Compare each model’s finished thickness, width and length to your usable cavity, and account for the PCM and harness on the length. If you are choosing between 2000mAh, 2500mAh and 3000mAh, we can map your exact space and runtime need onto the best-fitting option.

2500mAh LiPo Battery FAQ
What products typically use a 2500mAh LiPo battery?
2500mAh is common in tablets, portable Bluetooth speakers, medical monitors, mid-size power banks and higher-drain handheld tools. Our range covers both thin cells for displays and thick blocks for rugged or deep enclosures.
How thin can a 2500mAh LiPo battery be?
The slimmest is 3.6 mm (THOR-366890). A thin 2500mAh cell needs a larger area, so it works best behind a flat panel or display where width and length are available.
Can 2500mAh be built thick for a power bank?
Yes — the range goes up to about 16 mm thick, which suits power banks and rugged handhelds where depth is not a constraint and you want a compact footprint.
How long will 2500mAh last?
Runtime in hours ≈ 2500 ÷ average mA. A device drawing 250 mA runs about 10 hours; one drawing 125 mA about 20. Peak loads and cut-off voltage shift this — send your profile for an accurate figure.
Should I pick 2000, 2500 or 3000mAh?
It depends on the runtime you need versus the space you have. 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 2500mAh cell support high continuous current?
Continuous and peak current depend on the cell’s C-rate and the PCM rating. Many 2500mAh models support several amps continuous with higher short peaks. Tell us your currents and we confirm a suitable cell and protection board.
