Incident narrative
SaferProducts.gov consumer incident report 20260818-5CB9A-2147312232. Severity: No Incident, No Injury. Product: No labeling of manufacturer, make, or model Not labeled (52-Volt Lithium-ion battery, 17.5 Ah, Sanyo GA cells, 50 amp BMS, in [REDACTED] waterproof case with on-off switch, USB charging port, key lock). Incident: A 3 year old "aftermarket" 52-Volt lithium-ion e-bike battery spontaneously self-ignited while stored on the mounting plate on the bike frame in our garage. The fire/explosion melted one end of the battery case and split the seams of the case in multiple locations, emitting large quantities of noxious smoke and soot into the garage. The heat/fire damaged the steel bike frame, melting down the upper end of the battery case and nearby wiring. Three synthetic shoes stored on the concrete floor under the bike were totally incinerated into a pile of ash. The e-bike battery was NOT connected to A/C power, i.e. was not connected to a charger. The battery has no identifying make or model and is identified on the April 2023 sales receipt from the e-bike conversion shop as "52-V Lithium Battery, 17.5 Ah Sanyo GA cells, 50amp BMS, in a [REDACTED] waterproof case with on-off switch, USB charging port and key lock". There were no injuries.
