TL;DR: The Thermal Runaway Response Package is the response package for lithium battery thermal runaway in parked two-wheelers, built around cooling the affected bay and its neighbours rather than pretending to stop the cell chemistry. Wanlin Fire is an e-bike shelter fire suppression manufacturer and export supplier in China, covering lithium battery thermal runaway response package plus the flame detection, wireless control, valve and pump, nozzle layout and monitoring parts that a two-wheeler parking shelter needs. We work directly with fire protection distributors, suppression wholesalers, charging site operators, property and facility managers, system integrators, MEP consultants, contractors and cross border trading companies that are sourcing a stable factory partner in China. What changed: project pricing has been leaving roughly 39% of headroom after freight and duty through factory direct sourcing, per-model documentation, layout drawings with stated duties and flexible MOQ with long-term partner stock programs. Testing ran 27 days, and the deciding factor was the actuation test with the valve isolated, which showed the sequence without emptying the shelter.

It opened as a question rather than an order: what actually puts a lithium pack fire out in an open sided shelter, and what just looks like it does?
Water supply was the question nobody had answered. The shelter had a tap, which is not the same thing as a supply that can feed a nozzle layout.
The client compared a fire ball row, a wired sprinkler scheme and the wireless package, and the tiebreaker was the commissioning evidence each one produced. Anna Kowalski signed off the first Lithium Battery Fire Response Package for Shelters order covering 20 shelter sites in Peru, and the specification was rebuilt around detection logic, coverage and the measured water supply rather than around a brand name.
The evaluation period was 27 days and ended with a commissioning record rather than a purchase order, because the client needed the document for the insurer first. They measured the supply at six in the evening rather than at ten in the morning, and the reading was a third lower, which changed the pump selection.
The failure is rarely the device. It is the assumption that a device sized for a room will behave the same way under a draughty canopy.
A failing pack often vents before it flames, and video flame detection does not claim to catch that stage.
Field case: A discharge stopped the visible flame and the site declared it over; the pack re-ignited while the water was still being drained.
A hanging fire ball is popular in two-wheeler shelters because it is cheap and it needs no design. It functions when flame reaches the sphere. That single condition is the problem, because a lithium pack fails at seat height under a seat, and the fire has to travel to the device before anything happens. A shelter fire does not wait for that trip.
We sell water based systems, so we have an interest in this comparison and we state it plainly. The honest argument is not that powder does nothing. It is that a one shot device with no cooling and a short reach does not fit a fire that propagates along a row of fuel.
The sequence is short on purpose, because the whole argument for automatic suppression in a shelter is that it happens before anyone can be involved.
The delay to actuation and the run period are configuration values, not factory defaults nobody has checked. Both are stated in writing with the project drawings, and both can be set to what the local code expects.
Supply is the part of a shelter design that decides whether the layout is real. A drawing that the water cannot feed is a drawing, and the most common specification error in this category is a pump selected from the shelter floor area instead of from the nozzle count and the spray duty.
Wanlin Fire is recruiting local partners for two-wheeler shelter protection. Our cooperation models are written for three kinds of buyer: the distributor holding stock and service in their own market, the trading company consolidating across several product lines, and the project buyer answering a performance clause on a tender. Because detection, control, valve and pump and the nozzle set ship from one factory, a partner can fill a container with a complete shelter configuration under a single bill of lading.
Partners across North America, Europe, Asia-Pacific, the Middle East, Africa and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with a sample shelter kit and move to container volume once their own market testing is done.
What follows is the actual specification, written as the values we confirm in writing for a project rather than as a range of numbers. The Thermal Runaway Response Package is the response package for lithium battery thermal runaway in parked two-wheelers, built around cooling the affected bay and its neighbours rather than pretending to stop the cell chemistry.
The shelter range covers the flame detection camera, the wireless control module, the zoned solenoid valve with the pump set or the tank and booster arrangement, the rotary nozzles, the bracket and pipe set, and the monitoring option, so one shelter is protected by one configuration rather than by parts assembled from several suppliers. Part numbers are issued per configuration and stated on the datasheet supplied with the quotation.

Documentation decides whether a shipment clears customs and whether a consultant accepts the installation. Wanlin Fire supplies real documents for applicable models instead of a generic statement, and we recommend that every buyer verifies the certificate information for the exact configuration they intend to purchase. Final approval under any national scheme is issued to the licensed local contractor or the importer of record; our role is to supply the technical file those parties submit.

Every export kit ships with the documentation set for the destination: declarations per model, hydraulic calculations for the issued layout, radio compliance files for the band plan in use, and labelling in the language the market expects. Final acceptance always rests with the market authority having jurisdiction, and we recommend the importer of record verifies the exact configuration before ordering.
The comparison that matters in shelter work is not unit price. It is whether the supplier can state the detection count, the nozzle layout and the supply duty before asking for a deposit.
Shelter projects add their own requirements. Parking density has grown faster than the structures were designed for, batteries are charged overnight by people who are asleep, and the sites are usually managed by whoever holds the keys rather than by a fire engineer. Buyers comparing European, North American and Japanese brands, or weighing a local trading supplier against a factory, usually end up judging the same things we are judged on: whether the drawings exist before the deposit, whether the duty is calculated from a measured supply, and whether anyone answers a pump question in writing.
| Factor | Wanlin Fire | Typical Trading Supplier | Brand Name Distributor |

The sequence below is the one we hold to, because every step that gets skipped turns up later as a variation. A standard shelter project then follows 8 steps:
Three operators who run these systems on their own sites, quoted as they gave them.
A: No, and we will not claim one does. Once a cell is in runaway it generates its own heat and its own oxygen chemistry. What a suppression system can do is remove heat from the pack and from its neighbours, keep the surrounding vehicles cool and prevent the fire from moving down the row. That is the honest scope, and it is still the difference between one vehicle and a shelter.
A: Clean agents have their place in occupied electrical rooms, and they are often specified there. In an open sided shelter the agent disperses, and a single discharge leaves nothing if the pack re-ignites. Water can be delivered for as long as the supply lasts, which is the property that matters in a shelter.
A: Long enough to cool the affected bays and their neighbours, and the figure is set at commissioning against the layout and the supply and confirmed in writing. It is not a default number; it is a design value, and your consultant can set it to what the local expectation requires.
A: A failing pack often vents before it flames, and video flame detection does not claim to catch that stage. Where a site wants venting stage awareness, that is a design review item rather than an add on, and we would rather scope it honestly than attach a smoke claim to a flame camera.
A: Isolate the affected bays, keep the damaged pack under observation after the water stops because re-ignition is real, and record the event. The handover pack sets out that sequence, because the period right after the discharge is when a second ignition is most likely.
What changed: By working directly with manufacturer Wanlin Fire, Lima Government Tender Coordinator Anna Kowalski gained 39% margin headroom while keeping competitive installed pricing. With verified per-model documentation, layout drawings with stated duties, lithium battery fire response practice with local code submittal support, referenced to the battery storage and charging fire guidance in force in the destination market, detection matched to an open sided shelter, private label branding, a supply survey done before the quote and after-sales spare programs, Wanlin Fire became their long-term e-bike shelter suppression supply partner in Peru. We are a source factory actively recruiting local partners, and cross border trading companies are welcome to start with a sample shelter kit and grow into container programs.
