Surlon Power LFP | Floor Scrubber Lithium Battery 24V 105Ah

Product Overview

The Surlon Power FB02 is a 24V 105Ah LiFePO4 battery built for the cleaning machines that carry the floor-care workload in warehouses, supermarkets, hospitals and transport buildings. It sits in the same 24V class as the lead-acid block it is designed to replace, so the scrubber's brush motor, vacuum turbine and traction drive see a familiar voltage — but from a pack with 25.6V nominal voltage and 2,688Wh of stored energy behind it.

Inside the steel case sit LiFePO4 cells managed by an integrated battery management system, and the enclosure is sealed to IP65, which matters in a job where the machine drives through its own water recovery and parks in a wet bay. The case measures 400 × 325 × 222 mm (15.75 × 12.80 × 8.74 in), a format intended for the battery compartment of a 24V walk-behind scrubber and the smaller ride-on machines that use the same pack class.

Weight is the part most fleets underestimate. A lead-acid set is heavy, and the machine's deck pressure and stability were balanced around that mass. On this pack the counterweight is not fixed at the factory; it is configured for the machine it goes into, so the balance the operator is used to can be kept instead of discovered to be wrong on the first wet floor.

We build it as a cleaning machine battery producer working directly with scrubber manufacturers, distributors and facility maintenance teams. The pack can therefore be quoted as a replacement for an existing 24V machine or specified into a new cleaning machine design, with counterweight, connector and communication details agreed against your equipment rather than a generic template.

Key Advantages

• Voltage that holds through the shift. A LiFePO4 pack keeps its working voltage far flatter than a lead-acid block of the same class, so brush pressure and vacuum suction stay consistent from the first aisle to the last instead of fading as the battery runs down.
• Current headroom for combined loads. Rated at 0.5C continuous and 1C peak, the pack has room for the moments when brush, vacuum and traction draw together, such as climbing a ramp while still picking up water.
• Counterweight set to your machine. Weight without counterweight is customizable, so the pack can be brought close to the mass of the lead-acid set it replaces and the deck pressure and stability your operators know are preserved.
• No memory to manage. Crews can top up over a lunch break or between shifts; there is no memory effect to condition out and no deep-discharge routine to schedule.
• Fit checked before the order is built. We review case, connector, cable route and hold-down points against your compartment drawing, so a 24V lithium battery for walk-behind scrubbers arrives as a machine-specific unit rather than a generic block.
• Quiet, fume-free indoors. There is no gassing on charge and no acid mist, so the pack can be charged in the corridor or back room where the machine is parked rather than in a ventilated battery room.

Long-Life Lithium Replacement Solution

Cycle life is where a lithium retrofit pays for itself. This 24V 105Ah LiFePO4 battery is rated for more than 4,000 charge and discharge cycles, and a cycle here means what it means in a real cleaning schedule: a shift's work followed by a recharge. A lead-acid set in the same machine is normally retired far earlier, and it loses capacity gradually along the way, so the operator feels the difference as shorter runs and more frequent charging rather than as a sudden failure.

Four thousand cycles is a laboratory rating under defined charge and discharge conditions, so treat it as a comparison figure rather than a promise about your building. Depth of discharge is the biggest variable: a machine that runs one shift and is recharged overnight asks far less of the pack than one run flat twice a day. Temperature is the second — a pack charged in a cold yard or stored next to a boiler ages differently from one kept in a conditioned plant room. The charger is the third: a profile written for lead-acid will not necessarily treat a lithium pack correctly, and getting that right protects the cycle count you paid for.

For a fleet the practical effect is fewer batteries in the stores. Instead of keeping a spare lead-acid set per machine and swapping mid-shift, many operators move to one pack per machine plus a top-up between shifts, which also takes the watering round and the acid handling out of the maintenance schedule.

If you are replacing a set of lead-acid blocks rather than a single battery, tell us how the old set was configured — voltage, capacity and how the blocks were wired — so the replacement is checked as a system rather than as a one-for-one swap.

Maintenance-Free Operation

• No watering round. The cells are sealed, so there is no electrolyte level to check, no distilled water to carry to the charging bay and no top-up to squeeze into a shift change.
• No acid to handle. No spill kit, no neutralising powder, nothing corrosive stored beside the machine, and no corroded posts to brush clean before a charge.
• No terminal servicing schedule. The connection that matters on this pack is the main connector, and it is checked by eye rather than through a maintenance routine of cleaning, greasing and re-torquing.
• Labour goes back into cleaning. The hours a crew spends topping up and cleaning lead-acid batteries come out of the same budget as the floor work, and on a multi-machine site that is a visible saving every month.
• Charging stays simple. Lithium does not need an equalisation charge or a deliberate full discharge to stay healthy, so a partial top-up between shifts is a normal way to run the pack rather than something to avoid.
• What maintenance-free still means. Keep the case dry, check the main connector and cable for damage or looseness, store the pack within its stated conditions, and never open the housing. If a machine cuts out repeatedly, contact us before anyone tries to reset or repair the pack.

BMS Safety Protection

An integrated battery management system sits between the cells and the machine and watches voltage, current and temperature continuously. When something moves outside its safe window it acts: overcharge at the end of a charge cycle, over-discharge when a machine is left running on a flat pack, over-temperature in a hot plant room, short circuit in a damaged cable, and the abnormal conditions that come before a failure.

In service the protection usually shows up as a pack that stops rather than one that misbehaves. If a machine cuts out mid-aisle, park it, let everything settle, check the charger and the cable, and restart; if it happens again, call us before anyone opens the case.

The steel housing is part of that protection, not decoration. Rated IP65, it keeps dust out of the cell compartment and stands up to the water a scrubber throws when the recovery tank is emptied or the machine is hosed down in a wash bay. Steel also takes the knocks of a battery bay better than a thin plastic shell, which matters when a pack is lifted in and out of a compartment at the end of a night shift.

Temperature is managed by the same system. The charge window is deliberately narrower than the discharge window, so a machine working in a cold store can keep running while the pack is brought somewhere warmer to charge; the specification table below lists both ranges.

Two things the electronics cannot replace: a correctly matched charger and sound wiring. If either is wrong, the pack will protect itself by refusing to work and the machine will look faulty when the real problem is upstream.

Commercial Cleaning Applications

• Supermarkets and grocery store floors. Night crews run walk-behind machines down aisles between restocking and cleaning windows, so a pack that finishes the shift without sagging keeps brush pressure even on the last pass. Charging happens in a back corridor, which is only practical with a sealed, fume-free battery.
• Warehousing and logistics centres. Long runs on concrete, dust from pallet movement and dock areas that never fully dry make this the toughest duty in the list, and opportunity charging at breaks matters more here than anywhere else. The 24V lithium battery for walk-behind scrubbers is usually the first pack a site like this tries before standardising across a fleet.
• Hospitals, clinics and care homes. Cleaning happens around patients, so noise, fumes and acid handling all count against a battery. A sealed pack can be charged inside the building and moved past occupied areas without a ventilation requirement.
• Transport hubs and airports. Cleaning windows are short and machines rotate through them, so a pack that takes a partial charge between rotations covers more floor than one that needs a long cool-down before it can be used again.
• Contract cleaning fleets. When several machines of the same class run from one depot, keeping a single pack standard simplifies spares, charger settings and operator training across the whole crew.
• Building maintenance teams. Parking decks, atriums and service corridors in commercial property are handled by small in-house teams who would rather clean than service batteries, which is where the maintenance-free side of this pack earns its place.

Technical Specifications

Charging & Installation Checks

1. Log the machine. Note the scrubber model, its controller voltage range, and which motors run together — brush, vacuum and traction — with the current each one draws.
2. Measure the bay. Record length, width, height, hold-down points and the cable route, then compare them with the case dimensions in the specification table, allowing space for the connector and a service loop.
3. Check the charger before anything else. Note the charger model, its output profile and termination behaviour, and whether it has a lithium setting; a lead-acid profile is not automatically suitable for this pack.
4. Match the connection. Confirm connector type, pinout and polarity, cable length, and the rating of the main fuse or breaker between pack and machine.
5. Set the counterweight. Tell us the mass of the lead-acid set being removed so the weight configuration keeps the machine's balance and deck pressure.
6. Run a full-shift trial. Before a fleet rollout, put one pack through a complete shift of the machine's normal work, log runtime, and check that the pack stays inside its temperature range and the BMS does not trip.
7. Record the result. Write the pack serial number, charger setting and trial runtime into the machine's maintenance file, so the next replacement is a like-for-like decision rather than a fresh investigation.

OEM Customization Options

Ordering & Delivery

• Start with the machine, not the part number. Send the scrubber model, controller voltage, bay drawing, charger details and a photo of the connector, and the offer can be built around your equipment instead of a generic block.
• Agree the counterweight when you order. The mass without counterweight is set per machine, so confirm the figure while the order is being specified rather than after the pack is built.
• Ask about trial units. Your sales contact can tell you whether a trial unit is available for your machine and what the terms would be.
• MOQ and lead time. Both depend on the configuration and the quantity you need; ask for the current figures for your order rather than assuming a stock item.
• Packing and transport. Lithium packs move under dangerous-goods rules; ask which packing method and which transport documents are supplied for your route and destination.
• Payment and delivery terms. Confirmed in the offer for your market, along with the currency and the point at which responsibility changes hands.
• Documents. Ask which of the listed certificates and test reports apply to the exact pack revision you are buying and to the market where the machine will operate.
• Your configuration stays on file. As a cleaning machine battery producer we hold the agreed specification, counterweight setting and connector details for repeat orders, so a second batch matches the first.

Product Overview

The same battery is supplied for industrial floor scrubber and commercial cleaning machine fleets as well as for single-machine replacement, and it is offered as a lead-acid replacement battery for equipment already in service. It comes from a LiFePO4 battery manufacturer that also acts as an OEM lithium battery supplier, so buyers needing their own branding, packing or a particular configuration can ask for a project quote; the exact options, order quantities and lead times are confirmed with the supplier at that stage.

Technical Support & Model Matching

Technical questions reach the people who build the packs. Our engineering group in Shenzhen reviews your device's voltage window, load profile, enclosure space and charger before proposing a configuration; our sample group then builds units so you can validate fit and runtime before production. Cell selection, BMS design and pack assembly stay in-house, with quality checks in process and at final inspection, and a documentation team handling certificates, test reports and shipping papers. When a unit behaves unexpectedly in the field, our engineers help trace the fault and advise on installation and commissioning.
