Surlon Power LFP| Lighting Battery-LFP 3.2V1.6Ah

Product Overview

The LB01 is a compact LiFePO4 pack built for small lighting fixtures — the kind of battery that sits inside an emergency luminaire, a garden or path light, a portable work lamp or a low-power standby unit. It uses lithium iron phosphate chemistry rather than nickel-cadmium, nickel-metal-hydride or a small sealed lead-acid block, so the light sees a steady voltage across most of the discharge instead of fading through the run.

Where it sits in a lighting build

Inside the fixture the pack is charged between operating periods and discharges through the LED driver when the light is called on. In an emergency unit it also sits on standby for long stretches, holds its charge and then has to deliver a defined backup period when mains power drops. In a solar fixture it is fed by a panel and controller through the day and carries the lamp through the night. Both cases ask the same things of the battery: stable voltage, predictable behaviour as the temperature falls, and a shape that disappears into a tight housing.

Who we build it for

Lighting OEMs and distributors use this format when a product has to be small, light and repeatable from batch to batch. Typical projects are a new fixture under development, a battery change inside an existing design, or a consolidation of several small pack sizes into one family. We work as a mini LiFePO4 battery supplier for these projects: the pack leaves the line with your connector, your lead length and your labelling requirement, rather than as a catalogue part that has to be adapted afterwards.

Why the rating is only the starting point

Nothing about a 3.2 V nominal figure makes a pack a substitute for the battery already inside a fixture. A different driver window, a charger set for another chemistry, or a housing that only clears the old case by a millimetre will each stop the project. Whether the answer is this pack or a 6.4V compact battery for solar lamps, the checks that decide fit — driver window, load, connector, charging and a demonstrated runtime — are worth completing before a sample is built, not after it arrives.

Compact Pack Fit and Installation Space

• Compartment clearance — the case is a slim rectangle and the drawing carries a tolerance on every side. Measure the actual cavity rather than the old battery, and allow for moulding draft, foam or any potting the fixture uses.
• Retention method — decide up front whether the pack is held by a bracket, an adhesive pad, a strap or a moulded pocket. Retention decides where the lead leaves the case.
• Lead route and bend radius — the cable needs a path back to the driver with no hard fold at the exit point. Give us the distance and the direction the lead should travel.
• Service access — if a technician will ever unplug the pack, the connector has to be reachable without stripping the whole gear tray.
• Distance from heat — the LED board and the driver are the hot parts of the fixture. Note how close the pack sits to them and whether any air moves through the housing.
• Weight and movement — at this format the pack does not need a heavy cradle, but the holder still has to stop it shifting when the fixture is knocked or shipped fully assembled.
• Two-cell housings — where a solar lamp needs more voltage than one cell can give, we build it as a 6.4V compact battery for solar lamps from two cells, then review the housing around the longer case from the start.
• Drawing revision — approve the pack drawing against the latest fixture drawing, and tell us when either one changes, so a released build does not drift from the approved one.

Matching the Battery to Your LED Driver and Load

1. Send the driver's full input-voltage window, not only its nominal figure — the top and bottom of that window decide whether a 3.2 V pack sits inside it.
2. Give the normal operating current at each brightness setting, plus the start-up demand in the first moments after switch-on.
3. Describe the dimming or multi-mode behaviour: how many levels, how long the fixture normally stays in each, and whether any mode runs continuously.
4. List the loads that stay live while the main light is off — indicator LEDs, sensors, radio modules, standby circuitry — because they drain the pack between operating periods.
5. State the cut-off behaviour you need. A driver that keeps pulling below the pack's cut-off voltage will shorten the run and work the cells harder than necessary.
6. Confirm the temperature around the pack in the installed fixture, since driver heat and housing design set the real operating window.
7. Tell us if the fixture is designed around a two-cell input — a 6.4V 3Ah LiFePO4 battery pack is a different build with its own driver window, not this pack with a longer cable.
8. Attach the compartment drawing with the connector pinout and the polarity convention printed on your cable assembly, so the pack drawing can be checked against it line by line.

Charging Profile, Temperature and Demonstrated Runtime

Charging is where small lighting projects most often go wrong, because the pack is usually the last part of the design to be reviewed. Start with the charger or charge controller you intend to use and send its output limits and termination behaviour. A charger set up for nickel cells can push a LiFePO4 pack past its window or fail to stop cleanly at the top of the charge, and a solar controller chosen for a different battery type can do the same. We check your charger against the pack we are quoting, and we will tell you when a different unit is the simpler answer.

The charge figures in the specification table give you room to work. The standard charge current is conservative next to the maximum the pack will accept, which leaves headroom for a modest solar panel and a simple controller without working the cells hard on a bright day. If the fixture charges from a wall adapter in a few hours, that same headroom matters when the ambient temperature inside the housing climbs.

Temperature inside the luminaire

The charging and discharging windows listed for this model are identical, which is worth checking against your housing rather than assuming. An earlier summary of this model showed a wider discharge range than the table above, so approve your design against the current model datasheet rather than either figure taken on its own. A luminaire under glass in direct summer sun, or a pole-top housing with no airflow, can run well above the surrounding air temperature; tell us the expected internal temperature and the installation latitude.

What a runtime demonstration should record

Nominal energy does not turn into lighting hours by itself. Agree a demonstration using your own light, driver and operating modes, and record the starting condition of the pack, the ambient temperature, the load schedule, the cut-off point and the recharge that follows. Two fixtures with the same pack can produce very different runtimes if one dims at midnight and the other holds full output all night. On a two-cell solar build — a 6.4V compact battery for solar lamps, for example — the charging arrangement matters as much as the discharge: panel size, controller cut-off and the site's operating schedule decide whether the lamp recovers its charge every day. For emergency or standby equipment, add the backup duration, the standby charge mode, the changeover behaviour and the documents the finished luminaire has to carry. A battery datasheet on its own does not approve the complete lighting system.

Connector, Leads and Configuration Options

• Connector choice — the connector is built to your requirement. Send the mating half's part number or a clear photo of the plug and we will match the pack side to it.
• Lead length and gauge — state the run from the pack to the driver, and whether the lead passes through a gland, a hinge or a sealed wall.
• Polarity and wire colours — confirm which colour your assembly line treats as positive, so the connector cannot be plugged in reversed at final build.
• Sensor or signal leads — if your charger or driver expects a temperature sensor or a signal wire, say so before the drawing is issued.
• Labels — printing and labelling on the pack can be discussed with your sales contact; artwork and approval steps are agreed per project.
• Alternative builds — a 6.4V 3Ah LiFePO4 battery pack, or any other capacity or voltage, is quoted as its own configuration with its own drawing; it is not this pack relabelled.
• Line-side presentation — if the pack goes into a sub-assembly, agree how it reaches the operator and which end of the lead is pre-routed.

Prepare an OEM Lighting Battery Inquiry

1. Describe the fixture and where the pack sits in it — an emergency luminaire, a garden or path fixture, a portable work light, or a two-cell solar lamp build.
2. Send the driver details: input-voltage window, topology and the operating modes it runs.
3. Give the load profile and the target runtime for each mode, with the ambient temperature you expect inside the housing.
4. Attach the compartment drawing, the retention method and the space left for the leads.
5. Include the connector part number, lead length, polarity and any sensor lead your charger expects.
6. Name the charging source — mains adapter, solar panel and controller, or a shared DC bus — together with its output limits.
7. Mark which requirements are fixed and which are still open; it keeps the configuration review honest and shortens the loop.
8. State the sample quantity, the forecast volume and the destination country so the quotation and the paperwork match your market.
9. List the documents your customer or market requires, and ask for the current datasheet and drawing revision with the quotation.
10. Confirm order quantity, production lead time, packing and shipping arrangements with your sales contact — those are quoted per project rather than fixed in advance. We handle these enquiries as a mini LiFePO4 battery supplier working from drawings, so the more of this list you can answer, the faster a usable configuration comes back.

Storage and Line-Side Handling

• Storage window in practice — the specification table gives -20 °C to 65 °C, but treat that as the outer limit a pack may briefly see, not a comfortable shelf condition. A cool, dry store that stays well away from freezing and well below the top of the range keeps both the cells and the sleeve in better shape than a shelf beside a loading door or under a roof light.
• Charge level for a long stay — LiFePO4 holds its charge far better than lead-acid, but not indefinitely. Tell us how many months a batch will sit in stores before it reaches the line and we will confirm the storage charge level and the refresh interval for this model; do not carry one rule across every pack you buy.
• Keep the cartons closed — issue packs in their original sealed cartons until they are drawn for a build. An opened sleeve left on a bench gathers dust and moisture, and cartons stacked directly on a cold concrete floor pull condensation through the cardboard. Use a pallet or a shelf.
• Rotate by batch — mark the receipt date on every carton and issue the oldest first. When a lighting project pauses for a quarter, the batch behind it should not be buried under newer deliveries; a batch number on the stores record also lets a finished fixture be traced back to the packs that went into it.
• Carry the case, not the lead — at 55 g the pack is light enough to be tossed across a workbench, which is exactly how the wrap gets nicked and a connector pin gets bent. Hold the case, keep the plug capped or bagged, and never let packs share a tote with loose screws, offcuts or other metal.
• Inspect on receipt — look for a dented case, a torn sleeve, a deformed or pushed-in connector, and any pack that appears swollen. Set failures aside in quarantine with the batch number and photographs rather than sending them to the line, and raise them with us before the batch is released.
• Stage a shift at a time — bring the quantity one shift needs to the bench and leave the rest in stores. A pack left on the bench overnight is a pack that can be charged from the wrong adapter, knocked onto the floor, or mixed into a different build; a labelled tote per build keeps the two configurations apart.
• Let cold packs settle — if a delivery has spent the night in an unheated warehouse or a van, leave it in its carton until it reaches room temperature before charging it or sealing it into a luminaire. Condensation that forms inside a closed housing is difficult to find once the fixture is assembled.
• Keep the paperwork with the batch — the transport documents that arrive with a lithium consignment belong in the batch file, not in the bin, so the papers can be produced when a customer or a carrier asks for them.

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.
