Replacement Battery for Teufel Rockster Go 2
This lithium-polymer pack replaces the original cell in the Teufel Rockster Go 2 speaker. It delivers 5200mAh at 3.7V and matches the factory dimensions of 68.60 x 38.50 x 19.70mm. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. Certified to ISO9001, RoHS and CE standards.
Practical Limits of the 1S2P Lithium-Polymer Pack
The single-series, dual-parallel layout fixes the nominal voltage at 3.7V and the capacity at 5200mAh, so runtime cannot be extended without a larger enclosure. The pack weighs 95.0g and fits only the Rockster Go 2 chassis; it will not suit other Teufel models or third-party speakers. Full capacity is reached after two or three complete charge cycles.
When the Upgrade Is Worth It
Swap the original battery when playback time drops noticeably or the speaker no longer holds a charge through a full session. The decoded chip ensures plug-and-play compatibility with the existing fuel gauge and charging logic. Users who need more storage or a second hot-swappable pack should look elsewhere, as this is a direct one-to-one replacement only.

Questions about this item
Does this 5200 mAh pack come in any other capacity?
The replacement is offered in the single 5200 mAh / 19.24 Wh configuration that matches the original Teufel Rockster Go 2 specification.
What does the 5200 mAh rating mean for real-world playback time on the speaker?
It restores the factory runtime the Rockster Go 2 was designed for; actual hours depend on volume level and audio content.
The pack uses an INR18650 1S2P layout — what voltage does that deliver to the speaker?
The 1S2P arrangement provides the nominal 3.7 V the speaker expects, with the 5200 mAh capacity split across two parallel 18650 cells.
