Lithium ion and lithium polymer batteries now power nearly everything we touch, including phones, laptops, e bikes, tools, vehicles, and even our homes. When they fail, they do not just “go dead.” They can erupt into intense fires, explode without warning, and fill enclosed spaces with toxic smoke and super-heated gases. For victims, that means life changing burns, respiratory damage, and permanent disability. For families, it can mean losing a loved one in a fire that should never have happened.

At Clark, Fountain, Littky Rubin & Whitman, we focus on catastrophic injury and defective product cases, including lithium-ion battery fires and explosions across Florida and nationwide. Our lawyers and experts understand both the engineering that caused the failure and the legal strategy needed to hold large manufacturers, distributors, and retailers accountable.

How Lithium-Ion Batteries Fail: Thermal Runaway and Internal Defects

Lithium ion batteries store a lot of energy in a small package, which is why they are so useful and so dangerous when something goes wrong.

Thermal runaway: the chain reaction inside the cell

Thermal runaway is a feedback loop where a cell begins to overheat, the heat triggers internal reactions that produce more heat, and the temperature skyrockets until the cell vents or explodes. This can drive internal temperatures above 1,000°F (around 537°C), hot enough to ignite nearby materials and propagate fire to neighboring cells in a battery pack.

Common internal failure modes include:

• Internal short circuits: Contamination, misaligned components, or damaged separators allow the anode and cathode to touch, creating a short that rapidly generates heat.
• Separator failures: The thin polymer film separating positive and negative electrodes can tear or melt under stress, shock, or overheating.
• Lithium dendrite growth: Tiny metallic filaments can grow through the separator during charging, especially in cheaper or poorly controlled cells, eventually piercing the separator and causing a short.
• Battery Management System (BMS) failures: The BMS is supposed to monitor voltage, temperature, and current, and shut down the pack if it detects dangerous conditions; when it is under engineered or defective, unsafe conditions can continue until the battery fails catastrophically.

From a legal standpoint, these failure modes are often signs of:

• Defective design (unsafe cell chemistry, inadequate venting, poor thermal management).
• Defective manufacturing (contamination, improper welding, inconsistent materials).
• Inadequate warnings (no guidance on safe charging, storage, or disposal).

Our role is to take these internal technical failures and prove that they resulted from corporate choices, not from random chance or “user error.”

High-Risk Products: Where Lithium Batteries Go Wrong

Lithium ion cells appear in many different products, but certain categories show especially serious patterns of failures. We handle cases involving, among others:

E Scooters and E Bikes (Micro Mobility Devices)

E bikes and e scooters ride over potholes, curbs, and rough pavement every day, which exposes their battery packs to constant vibration and impact. Solder joints can crack, welds can fatigue, and pack housings can open just enough to let moisture and debris reach the cells. The risk increases when riders use cheap, non UL listed chargers or replacement batteries that do not match the original specifications.

Typical defects include:

• Poorly secured cells or welds that fail under real world riding conditions.
• Under designed BMS circuits that cannot keep cells balanced or prevent over charging.
• Packs installed in tight, unventilated compartments near combustible materials (like apartment hallways or storage closets).

When these devices ignite in homes or multifamily buildings, fires can spread rapidly before anyone realizes the source. We investigate the bike, charger, and entire supply chain to identify every responsible party.

Power Tools and Garden Equipment

Cordless drills, drivers, mowers, trimmers, and blowers are often dropped, thrown into truck beds, and left in garages that swing from extreme heat to cold. That combination of mechanical shock and temperature stress accelerates internal damage and promotes dendrite formation.

In these cases, we often see:

• Packs with inadequate casing or cell spacing, making them vulnerable to puncture or crushing.
• Thermal management that does not account for charging in hot garages or vehicles.
• Warnings that fail to explain realistic hazards of leaving packs on chargers indefinitely or in extreme temperatures.
• A power tool battery fire in a garage can quickly involve vehicles, flammable liquids, and stored building materials, causing severe property damage and burn injuries.

Portable Power Banks and Charging Bricks

Portable power banks pack multiple cells tightly into compact enclosures and are often sold at low prices, sometimes with questionable quality control. Fast charging features can drive cells harder, increasing heat and the risk of dendrite growth or other internal damage.

We focus on:

• Whether the cell design and separator materials were appropriate for the charge rates advertised.
• Whether the manufacturer properly tested for repeated fast charge use over the life of the device.
• Whether safety circuitry could realistically prevent over current, over temperature, and over voltage situations.
• When a power bank explodes in a bag, on an airplane, or on a nightstand, the injuries and property losses can be substantial.

Laptops, Tablets, and Smartphones

Thin devices leave little room for error. Batteries are squeezed into tight cavities along with processors and power electronics, leaving minimal margin for swelling or misalignment. When a phone or laptop is used or charged on a bed, couch, or other soft surface, heat has nowhere to go.

Common issues include:

• Mechanical designs that cannot safely accommodate normal levels of battery swelling.
• Inadequate thermal throttling or shutdown at high temperatures.
• Lack of clear warnings about charging on insulating surfaces or in confined spaces.

Victims often suffer burns to hands, thighs, groin, or face when these devices ignite in close contact with their bodies.

Vapes, E Cigarettes, and Mods

Vape devices are especially dangerous because the battery sits inside a rigid tube close to the user’s mouth and face. When a cylindrical cell vents hot gas in this configuration, the device can behave like a small pipe bomb.

We see failures related to:

• Unregulated mechanical mods that allow batteries to be pushed beyond their safe limits.
• Damaged or missing wraps that expose the metal can and allow shorts against other metal objects.
• Loose cells carried in pockets with keys or coins, creating direct shorts and sudden explosions.

These events can cause severe facial burns, dental injuries, eye damage, and tympanic membrane ruptures.

Electric Vehicles (EVs) and Hybrids

EV and hybrid traction batteries store enormous amounts of energy and are typically mounted low and near the vehicle’s perimeter. High speed crashes, undercarriage impacts, or structural defects can compromise the battery pack.

Failure modes include:

• Coolant leaks into the pack, which can cause short circuits and thermal events.
• Side wall ruptures where the pack casing is penetrated in a collision.
• Software failures that do not properly isolate damaged modules or trigger post crash “safe modes.”

EV fires are challenging to extinguish and may reignite hours later, increasing the risk to occupants, first responders, and bystanders.

Residential Energy Storage and Solar Systems

Home battery systems, often marketed as “solar walls” or BESS, store high voltage DC energy on or near living space walls, garages, or utility rooms. Firmware bugs in the BMS or misconfigured systems can allow dangerous conditions, such as overcharging or over current, to continue undetected.

We evaluate:

• BMS algorithms and sensor placement to see if they could realistically catch faults in time.
• Installation practices, including wire sizing, terminations, and protective devices.
• Whether installers and integrators followed manufacturer specifications and applicable codes.

A failure here can cause a structure fire that displaces families and results in major burn injuries or deaths.

Drones, RC Hobbies, and LiPo Packs

RC devices and drones commonly use lithium polymer (LiPo) packs, which use flexible pouches instead of rigid cans. That flexibility helps with weight and packaging but leaves cells more vulnerable to puncture, swelling, and mechanical damage.

After a crash or hard landing, a damaged pack may appear only slightly “puffed,” yet still be charged on a bench or in a child’s bedroom. A subsequent charge can ignite the pack with little warning.

We examine whether:

• The product provided adequate crash and post incident instructions.
• The charger and pack were compatible and properly limited charging parameters.
• The packaging and warnings matched the actual risk of indoor charging and storage.
• Types of Physical Injuries Caused by Battery Fires and Explosions

To pursue a defective lithium-ion battery case, there must be a clear physical injury or death tied to the event. These incidents frequently cause:

• Severe burns: Second and third degree burns to the face, hands, feet, torso, or groin, often requiring skin grafts, multiple surgeries, and extensive rehabilitation.
• Flash burns: Rapid exposure to super heated gases and flames that can damage both skin and underlying tissues in seconds.
• Hydrogen fluoride (HF) inhalation and toxic smoke exposure: Burning electrolytes and plastics release toxic compounds that can damage the lungs and other organs.
• Respiratory injuries: From smoke and chemical inhalation, leading to acute respiratory distress and long term breathing problems.
• Eye injuries: Corneal burns, foreign bodies from shrapnel, and permanent loss of vision.
• Tympanic membrane rupture and ear damage: Overpressure from explosions can tear the eardrum, causing pain, hearing loss, and balance issues.
• Lacerations and fractures: Shrapnel from cases, housings, and surrounding objects can cause deep cuts and broken bones.
• Amputations and crush injuries: In violent explosions or large industrial fires, limbs can be severely damaged or lost.
• Wrongful death: In the most serious events, victims may die at the scene or later from burn complications, infections, or inhalation injuries.

Our firm works with burn surgeons, pulmonologists, otolaryngologists, and other specialists to fully document these injuries and explain their long-term consequences to a jury.

Who May Be Liable in a Defective Battery Case

Lithium-ion battery claims are often more complex than a typical auto accident or slip and fall case. Multiple companies across the globe may share responsibility.

Potential defendants include:

Cell manufacturers: Companies that make individual cells, often overseas, may be responsible for design or manufacturing defects.

Pack assemblers: Businesses that combine cells into modules and packs, design the BMS, and integrate wiring and sensors.

Device manufacturers: Brands that design the overall product, such as an e bike, phone, tool, or vehicle, and specify how the battery is installed and cooled.

Component suppliers: Charger manufacturers, connector suppliers, and others whose parts contribute to the failure.

Retailers and distributors: Sellers who put dangerously defective products into the stream of commerce.

Installers and integrators: In solar and BESS cases, contractors whose poor installation or wiring mistakes created additional hazards.

We trace the product from cell fabrication through final sale and use, working to ensure that every responsible party is included in the lawsuit, wherever they are located.

What to Do After a Battery Fire or Explosion

Your actions in the hours and days after a battery incident can affect both your health and the strength of your legal claim.

Get immediate medical care.
Prioritize your health. Call 911 or seek emergency treatment for burns, smoke inhalation, and any blast injuries. Tell medical providers exactly what happened and that a battery explosion or fire was involved.

Preserve the device and battery components.
Do not throw away the device, charger, or any fragments. Do not let anyone “repair” it, and do not send it back to the manufacturer without talking to a lawyer first. If safe, place the remains in a non-combustible container away from living areas.

Document the scene and your injuries.
Take photos and videos of the scene, burn patterns, property damage, and any warning labels on the product and charger. Photograph your injuries over time to show healing and scarring.

Preserve packaging, receipts, and paperwork.
Keep boxes, manuals, warranty documents, and receipts. These items help identify the exact model, production runs, and supply chain path.

Avoid giving statements or signing documents.
Manufacturers, insurers, and retailers may contact you quickly. Do not provide recorded statements, admit faults, or sign releases without first speaking to your own lawyer.

Contact experienced defective battery counsel.
A lithium-ion battery case is not a routine personal injury claim. You need a firm that understands how to preserve evidence, coordinate expert inspections, and move quickly to protect your rights.

How Clark Fountain Investigates Lithium-Ion Battery Cases

Our investigation process is designed to meet the engineering complexity of these cases and the legal burden of proof.

Scene and origin and cause analysis.
We work with fire origin and cause experts and electrical engineers to inspect the scene, examine burn patterns, and determine where the fire started. The goal is to rule out other ignition sources and prove that the battery or charging system was the true cause.

Evidence preservation and lab testing.
We secure the device, battery, chargers, and related components under chain of custody protocols. Using advanced tools such as X ray computed tomography (CT) and scanning electron microscopy (SEM), our experts can examine internal structures, welds, and surfaces to pinpoint where the failure began.

Design and manufacturing review.
Our team analyzes cell chemistry, pack layout, BMS design, and thermal management features. We compare what the manufacturer built to what industry standards and safer designs require, including appropriate use of safety vents, separators, and protective circuits.

Standards, recalls, and prior incidents.
We research product recalls, safety bulletins, and prior incidents involving the same product line or manufacturer. Evidence that a company already knew about similar failures and failed to act can be powerful in front of a jury.

Medical and economic damages analysis.
Working with medical experts, lifecare planners, and economists, we quantify the full financial impact: medical bills, future treatment, lost income, reduced earning capacity, and the costs of living with permanent injuries and disability.

This combination of technical and legal work is what allows us to stand up to large manufacturers and their insurers in negotiation and at trial.

Why Experience Matters in Defective Battery Litigation

Defective lithium-ion battery cases are resource intensive and technically demanding. They require more than a basic understanding of personal injury law.

Key reasons to choose an experienced firm include:

• Technical fluency: You need lawyers who can talk comfortably with engineers about galvanic chemistry, BMS algorithms, thermal management, and failure analysis.
• Expert networks: The right experts, including fire investigators, electrical engineers, and materials scientists, make the difference between a strong case and speculation.
• Complex litigation experience: These cases often span multiple jurisdictions, involve foreign manufacturers, and demand careful coordination among many defendants and insurers.
• Trial readiness: Manufacturers take cases seriously when they know the firm has a track record of trying complex product cases to verdict.
