Finished dimensions depend on PCM, insulation, connector and wire-harness configuration and are confirmed on the engineering drawing for the selected model.

Choosing the Right 2000mAh Shape for Your Product

With 22 designs, 2000mAh gives you real freedom to match an exact cavity. You can take it as a 3.5 mm-thin panel (3.5 × 60 × 85 mm) behind a display, a long 4.5 × 39 × 98 mm strip for a bar or handle, or a 12 mm block (12 × 40 × 40 mm) for a compact deep housing. The decision is entirely about matching your usable cavity — compare finished thickness, width and length rather than assuming a standard footprint, and allow for the PCM and harness on the length. Between 1800mAh and 2500mAh, 2000mAh often balances runtime and size; send us your space and load and we will confirm.

    2000mAh LiPo Battery FAQ

    Why are there so many 2000mAh sizes?

    2000mAh is a very common target, so we maintain 22 pouch designs for it. That gives you unusual freedom to match an exact cavity — thin and wide, long and narrow, or short and thick — all at the same nominal capacity.

    How thin can a 2000mAh LiPo battery be?

    The slimmest is 3.5 mm (THOR-356085, 3.5 × 60 × 85 mm). A thin 2000mAh cell needs a larger area, so it suits a flat panel or display where width and length are available.

    Do you have a long, narrow 2000mAh cell?

    Yes — 4.5 × 39 × 98 mm (THOR-453998), useful for soundbars, handles and wand-shaped products where you have length but limited width or depth.

    How long does 2000mAh last in a portable speaker?

    It depends on volume and amplifier draw. As a rule of thumb runtime in hours ≈ 2000 ÷ average mA; a speaker averaging 200 mA runs about 10 hours. Send your load profile for a firm figure.

    Should I pick 1800, 2000 or 2500mAh?

    The sizes overlap, so we recommend choosing by your exact cavity and target hours rather than the number. Send both and we will map them onto the best option.

    Can a 2000mAh cell support higher current, and can I get samples?

    Continuous and peak current depend on the cell’s C-rate and PCM rating; several 2000mAh models support multi-amp continuous draw. Connectors and PCM are fully customisable, and prototypes are available before production.
