Replacement battery for Sena headsets

This 1100mAh 3.7V lithium pack replaces the original YT102540P cell in Sena 30K, 50S and SP46 communication units. It matches the factory dimensions of 41.3 x 25.0 x 10.0mm and weighs 43.2g for a direct fit. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Riders needing a fresh cell for listed models

Suits owners of a 30K, 50S or SP46 headset whose battery no longer holds charge and who can confirm the YT102540P part number. Not for riders using other Sena models or different brands, nor for anyone who cannot verify the exact part number before purchase. The single-pack format means multi-unit fleets need multiple packs.

1100mAh capacity at 3.7V

The 1100mAh rating at 3.7V delivers 4.07Wh, the key figure that determines runtime between charges. If your original cell shows the same voltage and capacity, this pack restores factory run-time; if your device requires a different capacity or voltage, this is not the correct part.

Questions about this item

What voltage and capacity does the 3.7 V 1100 mAh lithium cell deliver?

The replacement cell is rated at 3.7 V and 1100 mAh, providing 4.07 Wh of energy for the Sena 30K, 50S and SP46 headsets.

Will the 41.3 x 25.0 x 10.0 mm pack fit the battery compartment of a Sena 30K?

Yes, the 41.3 x 25.0 x 10.0 mm dimensions match the original YT102540P pack so it seats correctly in the 30K, 50S and SP46 units.

How do I install the battery without damaging the connector or sealing?

Open the headset casing, disconnect the old pack, plug the new 3.7 V 1100 mAh cell into the same JST connector, then reseal the housing — forcing the connector backwards is the common mistake.
