Pack P/N DAKB014K0-T091J01LT (DynaPack, per the official MSDS — human-verified). The designation VM13-147 appears on documents and seller listings and is kept as a searchable reference. The same pack is reportedly used in the S4 and X4. The S3/X3 also carry a small secondary cell inside the Smart Cartridge — a "dead" bike is often the cartridge cell, not the main pack (see mikecoats.com teardown).
Diagnose it first: repair or replace?
