BatteryEVO S-1000-58.4

SaferProducts.gov consumer incident report 20250205-C4592-2147333423. Severity: Incident, No Injury. Product: BatteryEVO S-1000-58.4 (BatteryEVO Switching Power Supply S-1000-58.4 B). Incident: I purchased 48-volt lithium batteries from BatteryEVO.com for my [REDACTED] in the spring of 2024. In October, 2024, the charging unit that I purchased along with the new batteries began to release plumes of smoke from out of the cooling fan port. I subsequently discovered that internal electronics, including a capacitor were burned out. BatteryEVO customer service reluctantly agreed to send me a replacement charging unit. Just 4 months later, while charging my batteries, I walked into my garage and smelled the strong odor of something burning. I then noticed smoke emanating from the cooling fan of the replacement charge unit. I made a video recording of the smoke, and then the Arc-fault dedicated circuit breaker in my breaker panel tripped because there was a small arcing fire within the battery charger. It became obvious to me that there is an engineering defect in these charging units. I contacted BatteryEVO and explained the situation, and also suggested they contact their supplier/manufacturer of the charger units about this dangerous engineering defect. Several days later after not hearing back regarding my issue, I called BatteryEVO and was told that they would not issue a working replacement, and apparently, have no intention of taking corrective action regarding this defective device. It is only a matter of time before one of these charge units burns down a house or business, and potentially kills someone.
