Your bike's discontinued. Seller "compatibility" lists are wrong half the time, and the wrong pack is a fire risk. We verify every fit against the manufacturer's specs, teardown evidence and real owner reports — then tell you the three things to check on your own pack.
No claim ships on one source. Manufacturer specs, teardown photos and owner reports must agree.
Fit is decided by voltage, case length and discharge pinout — not by model name. We list all three.
We tell you what not to use — wrong voltage, wrong length, smart-BMS — as clearly as what fits.
Every page shows when it was last verified. Owner corrections are reviewed and merged.
