In June 2023, a golf cart charging in a garage in Jacksonville, Florida destroyed the home it was parked in. In September 2024, a golf cart charging in a shed in Homosassa, Florida caused a fire that spread to the structure with an estimated $20,000 in damage. In February 2025, a cart near Sarasota ignited during use, produced toxic gases, and required a specialized fire blanket to suppress. In one Florida community, St. Johns County officials reported that 80% of fires were caused by golf carts and e-mobility devices.
These are not isolated incidents. Lithium-ion battery fires across all categories surged 93% from 2022 to 2024. The US Fire Administrator testified before Congress in 2024 that in fires involving these batteries, there can be as little as 15 seconds from the first sign of smoke to thermal runaway, with windows blown out and fire burning through structures.
Golf carts are a big and growing part of that picture. Top manufacturers including Yamaha, E-Z-GO, and Club Car are producing lithium-powered carts at scale. E-Z-GO alone has placed more than 230,000 lithium-powered carts on over 3,750 courses. As those carts move from courses into private garages, driveways, and community storage areas, the fire risk moves with them.
What Makes a Lithium Golf Cart Battery Different From Lead Acid
Most golf cart owners who upgraded from lead acid to lithium did it for good reasons. Lithium batteries are lighter, charge faster, last longer per charge, and have a longer service life. Those advantages are real and the upgrade makes sense for a lot of owners.
What changes along with the performance is the failure mode. Lead acid batteries can fail in ways that are dangerous, but they do not enter thermal runaway. Lithium-ion batteries can, and thermal runaway is a categorically different kind of fire.
When a lithium-ion battery cell is damaged, overcharged, or develops an internal short, a chemical reaction can begin that generates its own heat. That heat accelerates the reaction, which generates more heat, which accelerates the reaction further. The process is self-sustaining and does not require external oxygen to continue. This is why lithium battery fires are so difficult to extinguish once they are fully underway, and why the US Fire Administrator's 15-second figure matters so much. By the time you smell smoke and turn around, the window for intervention may already be closing.
The critical thing to understand about automatic suppression in this context is the same thing that applies to every lithium battery application: once full thermal runaway is underway, no suppression system can stop it. The value of automatic suppression is catching a heat event early, before full thermal runaway develops, limiting the damage and preventing the fire from spreading to the garage, the shed, or the home the cart is parked next to. That early window is where the difference between a bad day and a total loss is made.
When and Where Golf Cart Fires Happen
The pattern in reported incidents points to two primary scenarios.
Charging in enclosed spaces. The majority of serious golf cart battery fires documented in recent years happened during or shortly after charging. A lithium battery that is overcharged, charged with a non-compatible charger, or that has developed an internal fault can heat up during the charging process. A battery generating heat in an enclosed garage or shed has nowhere for that heat to go. The fire that results has a structure right next to it.
Physical damage and degradation. Golf carts get bumped, driven over rough terrain, and generally treated as utility vehicles. A battery pack that has absorbed impact damage may have internally compromised cells that look fine from the outside. Cells damaged internally can develop fault conditions over time that lead to heating and, in some cases, thermal events.
Both scenarios have something in common: they often happen when nobody is there. Charging happens overnight. Carts sit in garages for days between uses. The fire starts without anyone present to notice the early signs and respond.
How BlazeCut Works in a Golf Cart Application
The BlazeCut T Series is a pre-charged flexible tube that routes through or around the battery compartment of a golf cart. The tube is both the heat sensor and the delivery mechanism for the FK-5-1-12 clean suppression agent inside it. No wiring into the cart's electrical system, no power source, no connection to the charger or the BMS. The system is passive and responds to heat through the physical properties of the tube material itself.
When temperature at any point along the tube reaches approximately 248 degrees Fahrenheit, the tube opens at the hottest point and discharges FK-5-1-12 directly onto the fire source. For a battery compartment fire developing during charging or after a fault, this early response is the intervention that matters. The system activates inside the compartment, at the source of the heat, before the fire has time to spread to the surrounding structure.
FK-5-1-12 is a clean gaseous agent. It is non-conductive, non-corrosive, and leaves no residue. It is safe for the battery cells, the wiring, the cart's electronics, and the surfaces of the battery compartment. After a discharge, you ventilate the space, assess what happened, replace the tube, and have the battery system inspected before charging again.
The tube is compact and flexible enough to route through most golf cart battery compartment configurations. Installation requires no modification to the cart's electrical system and no special tools. Most installs take under an hour. Service life is up to 10 years with no maintenance required.
The Garage Problem
The reason golf cart battery fires have destroyed homes and not just carts is where the carts are parked. A garage or enclosed shed shares walls, ceilings, and framing with a larger structure. A fire that starts inside a battery compartment and is not suppressed quickly has direct access to those materials.
A smoke detector in the garage is better than no smoke detector. But a smoke detector alerts you after smoke has built up enough to be detected, which in a fast-developing lithium battery fire may not be early enough to matter. A suppression system inside the battery compartment responds to heat at the source before smoke has time to travel anywhere.
If your golf cart charges in an attached garage, an enclosed shed next to your home, or any covered structure, the case for automatic suppression inside the battery compartment is the same case that applies to any lithium battery system in an enclosed space that runs or charges without constant supervision.

FAQ: Golf Cart Lithium Battery Fire Suppression
Can BlazeCut stop a thermal runaway once it has started? No. Once a lithium battery cell has entered full thermal runaway, the self-sustaining chemical reaction cannot be stopped by any suppression system. The value of automatic suppression is early intervention during the heat development phase before that point is reached, limiting damage and preventing the fire from spreading to the surrounding structure. Catching it early is where the protection lies.
Is FK-5-1-12 safe for the battery cells and cart electronics? Yes. FK-5-1-12 is non-conductive, non-corrosive, and leaves no residue. It is safe for battery cells, wiring, and electronic components. After a discharge, ventilate the compartment and have the battery system inspected before charging or using the cart again.
Will it activate from normal charging heat? No. The activation temperature of approximately 248 degrees Fahrenheit is well above the temperatures a healthy lithium battery system produces during normal charging. Even a battery running warm during a fast charge cycle stays far below that threshold under normal operating conditions.
Can I install it myself? Yes. The tube mounts with zip ties or simple brackets and requires no connection to the cart's wiring. Most battery compartment installations take under an hour with no special tools required.
What size system do I need? Sizing is based on the interior volume of the battery compartment. BlazeCut USA dealers can help you select the right tube length for your specific cart model and battery configuration.
What do I do after the system discharges? Ventilate the area and move away from the cart. Do not attempt to charge or operate the cart until the battery system has been inspected by a qualified technician. Replace the BlazeCut tube through an authorized BlazeCut USA dealer before reinstalling protection.
