YouTuber Clark, known for his channel “Clark’s Adventure,” has made headlines after a detailed teardown of a “Solid State Marine” 12V battery, priced at $1,250, revealed significant discrepancies between the product’s advertised features and its actual performance. The analysis linked the battery to WeLion, a Chinese supplier of pouch cells that NIO uses in its electric vehicle (EV) packs. Clark’s findings suggest that the battery contains volatile NMC chemistry rather than the fire-resistant solid-state technology claimed by the manufacturer. In a shocking demonstration, Clark simulated a charging fault, resulting in the battery venting, smoking, and ultimately catching fire, raising serious safety concerns.
Battery Composition and Claims
The teardown unveiled that the “Solid State Marine” battery is equipped with WeLion pouch cells, which are semi-solid-state cells similar to those in NIO’s 150kWh EV batteries. The analysis showed that the battery has a charge specification of 16.6V. This specification indicates the use of volatile nickel manganese cobalt (NMC) chemistry, contradicting the company’s assertion of employing non-flammable solid-state technology.
Clark pointed out that the real-world cycle life of the WeLion cells, as specified by the manufacturer, ranges between 500 to 1,200 cycles. This figure starkly contrasts with the claimed 3,000 cycles, suggesting that consumers may not receive the longevity they are promised. The discrepancy raises questions about the reliability and safety of the product.
Safety Test and Consequences
In a critical safety test, Clark simulated a realistic charging fault to assess the battery’s behavior under stress. The result was alarming; the battery began to vent, produced smoke, and ultimately caught fire, demonstrating that the liquid electrolyte, which the company denies exists, is indeed present. This incident serves as a stark reminder of the potential hazards associated with lithium-ion batteries, particularly those that may not meet safety standards.
Implications for Consumers and the Industry
The revelations from Clark’s teardown raise significant concerns for consumers considering the purchase of the “Solid State Marine” battery or similar products. With the increasing reliance on batteries in marine applications and electric vehicles, the demand for safe, reliable battery technology is at an all-time high. This incident highlights the importance of rigorous testing and transparency in the marketing of battery technology.
As the electric vehicle market continues to expand, manufacturers and suppliers must ensure that their products meet stated claims to maintain consumer trust and safety. The findings from Clark’s Adventure could prompt further scrutiny of other battery suppliers and compel regulatory bodies to enforce stricter guidelines for battery safety and performance claims.
