Product Overview
The 36V 150Ah LiFePO4 battery pack powers ride-on and walk-behind floor scrubbers, sweepers and the commercial cleaning machines built around them. Inside a sealed IP65 enclosure, 150Ah of lithium iron phosphate cells sit in a 12S1P arrangement, which gives a nominal pack voltage of 38.4V and 5.76kWh of stored energy.
A 36V battery for commercial floor scrubbers has to do more than hold a charge. It carries the brush motor, the vacuum and the traction drive through a shift, absorbs the current spike when a brush bites into a dry floor, and then accepts a full charge between shifts without being lifted out of the machine. That duty shaped this pack: a high-capacity LiFePO4 build with a working current sized for continuous scrubbing and headroom for the short bursts a scrubber asks for.
Most buyers arrive with a machine that already runs and a lead-acid set that is due for replacement. This is the lithium option for that machine — the same nominal voltage class, a flatter discharge curve under load than a flooded set, and no acid maintenance between shifts. Whether it fits is a separate question: voltage window, compartment space, connector and charger all have to line up, and we work through those with you before a pack is built.
As a floor scrubber battery supplier we would rather see the machine than the part number. If your site runs more than one machine type, send the whole list. A mixed fleet often needs two configurations rather than one compromise, and it is easier to settle that before the season starts than in the middle of it.

Cleaning Fleet Applications
- Warehouse and distribution floors. Ride-on scrubbers covering long aisles between racking — the classic duty for a 36V battery for commercial floor scrubbers, where the machine stays out for a full shift and returns only to charge or swap.
- Hospitals and care facilities. Smaller ride-on and walk-behind machines working wards and corridors, usually early morning or overnight when the corridors are clear and noise has to stay low.
- Shopping malls and commercial venues. Evening rounds across concourses, escalator surrounds and back-of-house areas, often with one machine shared between floors and charged on a fixed rota.
- Factories and workshops. Scrubber-sweepers handling metal dust, swarf and coolant residue, where the enclosure is regularly hosed down at the end of a shift.
- Airports, stations and transport hubs. High-hour machines on a strict charging schedule, where an unplanned stop strands a whole concourse rather than one aisle.
- Contract cleaning fleets. Several machine brands on one contract; standardising the pack and charger across the fleet simplifies spares and keeps the crews working from the same routine.
- Industrial sweepers. Ride-on sweepers where brush and vacuum load peaks hard at start-up over grit and debris, then settles into a steady draw.
Working Current and Peak Demand
The 75A working current is the figure that matters during normal cleaning: brush down, squeegee down, vacuum running, machine moving at working speed. That is the load the pack carries hour after hour, and it is the number to hold against the machine's controller and fuse ratings rather than the headline capacity.
The 150A peak is a different animal. It is available for up to 10 seconds at a time and covers the moments when the machine asks for everything at once — brush motors starting against a dry floor, the vacuum turbine spinning up, a ride-on unit pulling away from a standstill or climbing a ramp with a full recovery tank. Treat it as headroom for short bursts, not as a continuous rating. A machine that sits near 150A for minutes at a time will reach a protection cut-off long before the shift ends, and that is the pack doing its job rather than a fault.
Two checks catch most mismatches before they become breakdowns. First, the controller: its current limits and its low-voltage cut-off. A lithium pack holds a higher and flatter voltage than the lead-acid set it replaces, so the cut-off point needs to suit the new pack, and that setting belongs to the machine supplier. Second, the DC wiring: cable gauge, terminal condition, polarity at the connector and the condition of the latch.
If a 36V battery for commercial floor scrubbers is being considered for a machine with a large vacuum motor or a high-flow pump, send us the measured draw at peak along with the controller's limits. Matching a pack to a measured load is far quicker than matching it to a brochure figure, and it is the difference between a confident approval and a trial-and-error retrofit.
Installation and Commissioning
- Isolate and photograph. Switch the machine off, disconnect the battery, and photograph the bay, the terminal layout and the connector before anything comes out. Those photos are what we work from if a connector has to be matched.
- Measure the compartment. Check the tray against the pack dimensions and leave room for the cable bend radius, the hold-down bar and any lifting frame. A tape measure now saves a return later.
- Compare the interface. Note the connector type, pin count, polarity and cable length on the existing wiring loom, and confirm they match the 36V 150Ah LiFePO4 battery pack going in.
- Plan the lift. The pack is a two-person lift; use a sling or a second pair of hands rather than dragging it across the tray edge.
- Seat and secure. Set the pack flat, refit the machine's own hold-down, and never drill, cut or compress the enclosure to make it fit.
- Reconnect and check polarity. Terminals clean and dry, polarity correct, connector fully seated and latched, cables routed clear of the brush deck and any moving linkage.
- Set the machine up. Have the controller's low-voltage cut-off and current limits confirmed for a LiFePO4 pack before the first working shift; this is a conversation with the machine supplier, not a field guess.
- Commission on the floor. Run brush, vacuum, squeegee and drive functions in turn, watch for protection trips or warnings, then record the date, pack configuration and machine hours in the fleet log so the next service visit has a baseline.
Battery Management and Routine Care
- The BMS inside the pack. The integrated BMS manages cell protection and pack condition from inside the enclosure. The exact protection set and thresholds for this configuration are set out in the model specification — ask for it and we will send the version that matches your build.
- What IP65 covers in practice. Dust-tight, and protected against low-pressure water jets, which suits the wash-down that follows a cleaning shift. It is not a rating for immersion, and a pressure washer aimed straight into the connector will still do damage.
- The charging window. 0 °C to 55 °C. A pack that has spent the night in a cold store or an unheated loading bay should be brought into that window before it is put on charge.
- The discharge window. -20 °C to 60 °C covers the environments these machines normally see. Outside it the BMS limits or stops discharge, so cold-room work is better planned around a pack that starts the shift within range.
- What routine care actually means. Wipe the case, keep terminals clean and dry, check the connector latch and cable strain relief at service intervals, and keep the hold-down tight. There is no acid to neutralise and no corroded terminal to scrape.
- Storage between seasons. A machine that will sit idle for weeks should be stored part-charged rather than flat, in a dry place, and recharged before the season starts. The model specification gives the exact storage state of charge for this pack.
- Other components in the range. Our BMS range also includes the ESS 16S100A, ESS 16S200A and 4S150A boards for other pack builds, and our SLA replacement line includes a 12.8V 100Ah battery for fleets that also run 12V equipment on site.
Ordering, Documents and Delivery
- Start with the machine. Send the brand, model and year, plus a photo of the battery bay with the old set still in place. That tells us the compartment, the connector family and the charger the machine was built around.
- Send the measurements. Compartment length, width and height, the hold-down arrangement, and either the connector pinout or a clear close-up of the plug.
- Share the electrical picture. The charger model and its charging profile, the controller's current limits, and the continuous and peak current the machine actually draws.
- Agree the configuration and revision. We confirm the build against your machine and issue the specification for the exact revision being supplied, so the 36V 150Ah LiFePO4 battery pack on the drawing is the one that ships.
- Request the documents. Ask for the datasheet, the dimension drawing, and the test and transport documents available for this exact model and revision, then check them against your destination market's requirements before the shipment is booked.
- Settle the commercial side. Quantity, packing, lead time and shipping terms are agreed with your sales contact. If you want to validate a pack on your own floors first, ask about sample availability at the same time so the schedule is planned once.
- Approve before production. Sign off the specification sheet, keep a copy with the machine record, and quote the model reference FB11 on repeat orders so the same build is supplied to every site.
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.
FAQ
Is this a 36V battery or a 38.4V battery?
It is sold for 36V-class machines. The pack uses twelve LiFePO4 cells in series, so its nominal voltage is 38.4V, while the 36V figure describes the machine class it was built for. That is why the charger profile and the controller's low-voltage cut-off matter more than the label: give us both and we will confirm they suit this pack before you order.
Can it replace the lead-acid battery in my scrubber?
It can when the whole machine agrees with it, not just the voltage label. As a floor scrubber battery supplier we check six things before saying yes: the system voltage window, the battery bay dimensions, the connector and polarity, the charger and its profile, the continuous and peak current the machine draws, and any control or interlock the machine expects. Send photos and the machine model and we will go through them with you.
Does it need regular watering or electrolyte checks?
No. LiFePO4 has no flooded electrolyte, so there is no watering round, no hydrometer check and no acid residue to clean off the terminals. What it does need is a charger matched to its profile, dry connections, and a quick look at the connector and hold-down at each service interval.
Can I keep the charger that came with the lead-acid set?
Not without checking it first. Lead-acid charging profiles and a 12S LiFePO4 profile are not interchangeable, and a charger that cannot be set to suit the new pack will shorten its life or trip protection. Send the charger model and its output voltage and current, and we will tell you whether it can be used as it is, adjusted, or replaced.
How long will a charge last on a shift?
Stored energy is not a runtime figure. 5.76kWh tells you what the pack holds; how far it goes depends on the machine's brush and vacuum load, floor type, travel speed, squeegee settings and the temperature in the building. Compare it against the measured draw of your own machine, then run one pack through a normal shift on your floors before planning a fleet rollout.
