3.7V 1100mAh LiPo Batteries — Compare Sizes for Your Device
Fit an 1100mAh cell into a compact audio or communication device while balancing finished-pack size, runtime and a mixed audio-and-radio load.
Moving from 1000mAh to 1100mAh can be useful, but the enclosure must support the exact cell proportions and finished assembly. Compare listed dimensions, identify potential matches using estimated pack size, and verify load, protection and connector requirements before freezing the mechanical design. Include these checks in production sample planning.

Technical Overview
An 1100mAh LiPo battery adds runtime headroom just above 1Ah for compact portable audio and communication devices. At 1100mAh, geometry can matter as much as nominal capacity: the same rating can be built in very different thickness, width and length combinations. In devices such as a portable audio recorder or a wireless intercom, the load mixes audio processing, a small display and short-range radio activity, so the finished-pack envelope and steady draw matter as much as peak current. Select by the finished-pack envelope and actual load profile, not by capacity alone.
Find a 1100mAh LiPo Battery for Your Available Space
Enter the available battery cavity to screen listed 1100mAh models by estimated finished dimensions. Any result is a potential match, not a fit guarantee; PCM, insulation, wiring, connector position, tolerance and clearance require final review.
18 listed 1100mAh models
Finished dimensions depend on PCM, insulation, connector and wire-harness configuration and are confirmed on the engineering drawing for the selected model.
Fit 1100mAh into a Compact Audio or Communication Device
The listed THOR-354860 uses a nominal 3.5 × 48 × 60mm bare-cell envelope, while the narrower THOR-902055 uses 9 × 20 × 55mm. Both target 1100mAh, but each places the required volume on different axes of the enclosure.
An extra capacity step is useful only when the chosen geometry leaves space for the finished assembly and preserves the device's mechanical clearances.
Same 1100mAh capacity, very different geometry. The listed models below all store 1100mAh, yet each one asks for completely different space inside a device:
THOR-354860
3.5 × 48 × 60 mm — the thinnest listed 1100mAh cell. Thin and wide; suits a flat recorder or receiver body.
THOR-604040
6 × 40 × 40 mm — a compact square block. Suits a handheld communicator with a small footprint.
All three store 1100mAh, yet each needs different space. If thickness is the limit, start from the thin, wide models; if the handset is narrow, a thicker cell can shrink the footprint. The geometry, not the capacity, decides the fit.
Compare 1000mAh and 1200mAh geometries alongside 1100mAh if the project can trade a modest amount of runtime for a cleaner mechanical layout.
Validate 1100mAh Current Capability for Audio and Communication Loads
The 1100mAh rating describes charge capacity, not maximum continuous or peak current. In a portable audio or communication device such as an audio recorder, wireless intercom or translation device, the load mixes steady audio processing with display activity and short bursts of short-range radio transmission. Whether the cell sustains those peaks depends on the specific cell model, C-rate, internal resistance, PCM and temperature. Use the battery runtime and capacity guide for energy planning, then validate loaded voltage, pulse duration and low-state behavior with the actual electronics. A custom LiPo battery configuration should be reviewed when the standard assembly does not satisfy these constraints.
Bare Cell Size vs Finished Battery Size
Bare 1100mAh dimensions describe the pouch cell before the complete protection and interconnect assembly is finalized. Component placement may extend thickness or length.
In a translation device, intercom or wireless microphone, finished thickness and wire direction must be coordinated with the speaker, microphone, antenna and user-control layout.

How to Choose an 1100mAh LiPo Battery
Measure the Space
Record the maximum battery cavity: thickness × width × length.
Allow Clearance
Allow for manufacturing tolerance, insulation, assembly and long-term cell expansion.
Confirm the Load
Provide continuous and peak current requirements. Capacity alone does not define current capability.
Define the Assembly
Confirm PCM, connector, polarity, wire length, wire exit direction and labeling.
Verify With Samples
Confirm the final drawing, finished dimensions and sample fit before volume production.
Custom 1100mAh LiPo Battery Configuration
A custom 1100mAh pack review can cover pouch geometry, PCM, connector, polarity, wire length and routing, insulation, label and packaging. Feasibility depends on the combined mechanical and electrical specification.

1100mAh LiPo Battery FAQ
What size is an 1100mAh LiPo battery?
1100mAh LiPo batteries are available in multiple shapes rather than one standard size. Check the exact listed model dimensions and the finished-pack estimate for your enclosure.
Is bare-cell size the same as finished battery size?
Bare-cell measurements exclude at least some finished-pack elements. PCM, insulation, wires and connector placement can change the final mechanical envelope.
What current can an 1100mAh battery deliver?
Use the exact cell data and PCM design to confirm continuous and peak current. An 1100mAh capacity rating by itself is not a current rating.
Can an 1100mAh LiPo battery be made thinner?
A thinner or narrower 1100mAh option may exist, but reducing one axis usually affects another. Engineering must validate any custom envelope and capacity target.
Should I choose 1000mAh or 1200mAh instead of 1100mAh?
A 1000mAh cell preserves more enclosure margin; a 1200mAh cell adds runtime when the device can accept the larger finished volume. Compare finished-pack dimensions side by side rather than the capacity label alone.
Is an 1100mAh LiPo suitable for a portable audio recorder or wireless intercom?
It can be considered when the finished-pack envelope fits and the selected cell supports the steady audio processing plus display and short-range radio peaks. Confirm PCM behavior, connector routing, charging strategy and temperature range with the actual device electronics.
What should I check for a translation device or voice terminal?
For a translation device or compact voice terminal, coordinate finished thickness and wire exit with the speaker, microphone and antenna, and confirm the radio-transmit peak, charging strategy and temperature range with the actual electronics before committing the enclosure.

Why compare nearby capacities: A 1000mAh pack can preserve more enclosure margin. A 1200mAh or 1500mAh pack may extend operating time when the device can accept the added finished volume and charge time.
