S1 Dry Flush Sealing Toilet and S1 Adapter Kit recalled over fire hazard

The battery management system does not stop charging when the cell is at or below 0°C, which the recall notice says can cause damage leading to fire, smoke and toxic gas.

The S1 Dry Flush Sealing Toilet and the S1 Adapter Kit have been recalled because the battery management system does not inhibit charging when the cell is at or below 0°C, the recall notice says.1

Charging in that condition causes lithium plating, which the notice describes as cumulative, invisible damage that can later cause an internal short circuit and thermal runaway, risking fire, smoke and toxic gas release.1

As of October 1, 2026, the company has received no reports of incident or injury in Canada, the notice says.1
