July 13, 2026 — A recent incident report has brought to light significant safety concerns regarding Battleborn 100Ah 12V LiFePO4 Deep Cycle Batteries. The report details multiple alleged defects, including melting plastic components, loose electrical connections, and the potential for fires and venting gases, which the reporter claims are reproducible and widespread.
Product Details
Incident Overview
The incident report, submitted on June 12, 2026, by an individual who operates a channel dedicated to testing batteries and solar equipment, alleges a major fire safety issue with multiple Battleborn battery products. The reporter claims to have successfully reproduced the issue in a brand new battery using a battery cycle machine.
According to the report, a critical flaw exists where a piece of plastic at the main terminal and supply connection can melt, leading to a loose connection. This loose connection, the reporter states, can escalate to the entire battery melting and venting gases. Multiple videos documenting this reproducible defect have reportedly been posted online.
Following the initial videos, numerous other individuals allegedly came forward with similar experiences. Further testing by the reporter reportedly uncovered additional issues with larger Battleborn battery models. Specifically, it is claimed that these larger batteries lack a robust mechanical connection between cell packs. In high vibration environments, such as those found in RVs or boats (for which these batteries are advertised), this can lead to hot spots and cause a cell to vent. The reporter claims to have captured an instance of this happening during backyard testing on camera.
The report also references a class action lawsuit which specifically questions the plastic “sandwich” electrical connection. The plaintiff in this lawsuit is identified as the president of an organization, an individual reportedly instrumental in creating many of the UL standards for this type of equipment, who is also asserting a major defect.
The reporter states that the company has filed a lawsuit against them for sharing these findings. Despite this, the reporter emphasizes that these batteries are widely in use, and new reports of melting batteries continue to surface. Many consumers are reportedly experiencing batteries becoming “dead” due to loose connections, which are then at risk of melting without any apparent abuse. Examples cited include one individual who found 4 out of 6 of their batteries failed, and another with 11 out of 14 dead batteries, all attributed to this loose connection issue. The reporter suggests that this problem may be present in the majority of these battery banks, with many owners unaware.
When consumers reportedly seek warranty claims, the company is alleged to deny them, attributing the issues to improper installation. However, the reporter maintains that the defect is inherent and present in all batteries, even in factory-installed systems. The reporter also claims to have opened batteries and found multiple other hot spots and melting within the case. The reporter is currently compiling a database of users experiencing these issues and has substantial evidence, including test results and video documentation.
Safety Concerns
The issues reported with Battleborn 100Ah 12V LiFePO4 Deep Cycle Batteries and potentially larger models present significant safety concerns:
- Immediate Dangers: The melting of plastic components, especially at main terminals, can lead to exposed electrical connections, posing risks of electrical shock. More critically, the alleged melting and venting of gases indicate a high risk of thermal runaway, which can result in fire, release of toxic fumes, and explosions.
- Long-Term Risks: Batteries with loose internal connections or “dead” status, as reported, are not simply inoperable; they are potentially ticking time bombs. The underlying defect can lead to unexpected failures, short circuits, and fires at any time, even after prolonged periods of seemingly normal operation. The issue is described as being present even when following the manufacturer’s installation advice and in factory-installed systems, suggesting inherent design or manufacturing flaws that pose a continuous risk.
- Who Might Be Affected: Owners of Battleborn 100Ah 12V LiFePO4 Deep Cycle Batteries and potentially other models, particularly those using them in high-vibration environments like RVs, boats, or off-grid power systems, are at direct risk. Anyone in proximity to these batteries, including family members, passengers, or occupants of vehicles and homes where these batteries are installed, could be affected by a fire or gas release.
- Property Damage Potential: A battery fire can rapidly spread, causing extensive damage or total loss to vehicles, boats, RVs, and residential properties. The melting of components and venting of gases can also damage surrounding electrical systems and materials.
What Consumers Should Do
Given the severe safety concerns raised in this incident report, consumers who own Battleborn 100Ah 12V LiFePO4 Deep Cycle Batteries or larger models advertised for high-vibration environments should take immediate action:
1. Discontinue Use if Suspected: If you observe any signs of melting plastic, discoloration, unusual heat, swelling, or any strange odors emanating from your Battleborn battery, immediately discontinue its use and safely disconnect it from your system if possible.
2. Inspect Your Batteries: Carefully inspect all Battleborn batteries for any visible signs of melting plastic around the terminals or anywhere on the casing. Check for loose connections or any other irregularities. Do not attempt to repair the battery yourself.
3. Document Everything: If you encounter issues, take clear photographs and videos. Document all communications with the manufacturer regarding warranty claims, including dates, names, and what was discussed.
4. Report the Incident: File a detailed report with the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report contributes to a database that can trigger investigations and potential recalls.
5. Seek Professional Advice: Consider having your battery bank and electrical system inspected by a qualified and certified professional who is aware of these reported issues.
6. Contact the Manufacturer: Reach out to Battle Born Battery Products, LLC to report your concerns and inquire about potential solutions or recalls, even if previous attempts to obtain warranty service were unsuccessful. Be prepared to reference the alleged defect and the ongoing reports.
