Surlon Power LFP| Lighting Battery-LFP 9.6V1.5Ah

Product Overview

Most lighting projects reach us with the fixture already on the bench: a driver, a sealed enclosure, a fixed cable route, and a battery compartment that has to be lived with. The LB08 is a cylindrical LiFePO4 pack built for that space: a low-voltage source for compact luminaires and a 9.6V battery pack for LED outdoor lights, assembled with the connector and lead arrangement agreed for your build rather than a catalogue default.

A 9.6V 1.5Ah LiFePO4 battery earns its place inside a luminaire for reasons that show up in testing rather than on the label. The discharge curve holds a steady plateau through most of the run, so an LED driver keeps its output stable instead of dimming as the pack drains. LiFePO4 also holds charge well in standby, which suits fittings that wait months between outages and outdoor products that may see several overcast days in a row. The cells sit in a sealed cylindrical body that survives the handling and vibration of assembly and transport.

What has to line up before a sample makes sense

Matching nominal voltage is the easy part, and it is the least informative. The driver input window, the charge source, the load profile and the mechanical envelope decide whether a pack works in a fixture. The sections below walk through those in the order that saves the most rework, then set out the full specification and the documents we release for an approved revision.

What this pack is not

It is not a universal drop-in for whatever battery sits in the fixture today. Packs built for a different chemistry, a different charge profile or a different connector can carry the same voltage label and still fail validation. If your fixture needs more capacity, a higher voltage or a different envelope, we build those configurations too and will tell you when another pack in the range is the better starting point.

Lighting Applications

• Emergency and exit luminaires. The pack spends most of its life on maintenance charge and is called on only when mains fails, so charge retention and clean changeover matter more here than cycle count. A sealed cylindrical body also slots into the slim spine of an exit sign without needing a bespoke housing.
• Solar garden, pathway and bollard lights. A 9.6V battery pack for LED outdoor lights of this size is normally sized around a night-run requirement and recharged by a small panel through a controller, so the pack works in shallow daily cycles rather than deep discharges. Seasonal light levels matter as much as the rating — a dim winter week is the real test of the sizing.
• Portable work and inspection lights. Where the pack sits inside a handle or a slim body and the user notices the weight. The cylindrical format is easy to retain with a simple end cap and a foam shim.
• Signage and display back-up. Short, infrequent interruptions in signs, light boxes and display cases, where the job is to carry the panel through a brief outage rather than to run it for hours.
• Service replacement programmes. Lighting brands and installers often need to keep older low-voltage fittings running after the original pack is discontinued. Send the old battery and a compartment drawing and we will review what a current configuration can do, without claiming an identical substitute.
• Programme supply for lighting brands. As a solar lighting battery manufacturer we build this pack in repeat batches for lighting brands and importers, with the connector and lead set agreed per order rather than carried over from the last one.

Circuit, Charging & Installation Fit

1. Start with the driver input window. Send the LED driver's input-voltage range and its low-voltage cut-off. A pack whose working plateau sits above the driver's minimum, and whose cut-off arrives before the driver browns out, is a workable starting point; anything else needs a different configuration.
2. Describe the load rather than the wattage. Steady current in each brightness mode, the start-up surge when the driver first sees the pack, and any pulse or strobe behaviour. A pack sized for a steady load behaves differently when the same fixture draws a short repeated peak.
3. Set the runtime you need for each mode. Emergency backup, dusk-to-dawn running and dimmed standby are three different requirements. Say which one is the acceptance criterion, because one pack can meet one and miss another.
4. Match the charge source. A mains charger and a solar controller ask different things of a pack. Send the charger model or the controller's charge profile: the pack needs a LiFePO4 profile with the right termination, and a controller still set for lead-acid will either leave it undercharged or push it past its limits.
5. Check the envelope against a drawing. Compartment length and diameter, how the pack is retained, where the lead exits, and how much slack the assembly needs. A drawing review takes minutes; a tooling change takes weeks.
6. Lock the connector detail. Type, pin count, pinout, polarity, lead length and wire gauge. Two packs can look identical and be wired differently, and reversed polarity inside a sealed luminaire is an expensive thing to find at final test.
7. Name the destination market early. For emergency and exit-sign products the compliance obligation sits with the finished luminaire, not with the cell or the pack. Knowing the market at the start tells us which documents to prepare and which questions your own test house is likely to ask.

Sample Review Plan

A sample review is where a 9.6V 1.5Ah LiFePO4 battery either proves itself or does not, and the outcome depends as much on the test plan as on the pack.

Write the pass criteria before the sample ships

Decide what a pass looks like in advance: light output held through the required run, the pack reaching cut-off cleanly, charging from the real charger or controller, the pack seating in the actual enclosure, and the connector mating with no strain on the leads. Criteria written after the sample arrives tend to bend around whatever the sample happens to do.

Test on your own driver and charge source

Bench-testing on a laboratory supply tells you about cells. Testing on the driver, charger and controller the product actually ships with tells you about the system. If the pack replaces a lead-acid, nickel-based or another lithium battery, review the whole charging and load arrangement rather than the voltage label alone.

Measure temperature inside the enclosure, not on the bench

A pack that runs cool in open air can run considerably hotter in a sealed luminaire head. Measure at the pack surface in the installed condition and compare it with the charging, discharging and storage limits for the revision you are approving; if the margin is thin, that is a housing or duty-cycle conversation rather than a battery one.

Keep the numbers

Log runtime, current draw, surface temperature and the point at which the driver cuts out. Those records become the reference for the production revision and the first thing to check if a later batch behaves differently.

Confirm the revision you approved

Ask which specification revision and configuration will be supplied against your order, and check that production units match the sample you signed off. A deviation agreed on the bench carries little cost; the same change after tooling and connector purchasing does not.

Specifications

OEM Inquiry Preparation

1. Describe the fixture in plain terms. What the product is, where it is installed and how often it runs. A 9.6V battery pack for LED outdoor lights has a very different duty pattern from one behind an indoor exit sign, and that difference should be visible in the first paragraph of your brief.
2. Attach whatever already exists. The driver datasheet, the charger or charge-controller datasheet, the label or datasheet of the battery being replaced, a dimensioned drawing of the compartment and a photo of the existing connector. Partial information still moves the review forward.
3. State the acceptance criteria. Target runtime, brightness mode, the temperature the fixture sees in service, and anything your own customer or test house has already asked for.
4. Flag every deviation from the listed configuration. A different voltage, capacity, envelope, connector or protection requirement is reviewed as a configuration change rather than as a variant of the listed pack, and saying so up front avoids a second round of drawings.
5. Mark what is fixed and what is still open. If the enclosure is already tooled, say so; if the connector is still open, say that too. It tells us which parts of a proposal you can still change.
6. Say what you need back. A specification and drawing for review, a sample for bench testing, or a feasibility opinion on a proposed change — each leads to a different reply, so ask for the one you need next.
7. Keep a reference. Quote the revision or drawing reference in later correspondence so both sides are discussing the same document.

Documents & Model Reference

Ordering & Delivery

• Quantity and pricing. Pricing follows the configuration you approve and the batch size you order. As a solar lighting battery manufacturer we quote each lighting project on its own, so tell your sales contact the sample quantity, the expected production volume per release and how often you expect to reorder.
• Samples and schedule. Ask your sales contact about sample availability and the current terms before you commit to a validation date, and keep the sample schedule separate from the production schedule in your planning.
• Production timing. Lead time depends on the connector and lead set, the protection configuration and component availability at the time of order. Confirm the current lead time against your build plan instead of planning around a fixed figure.
• Packing. Tell us what your line needs — individual bagging, labelled cartons, a set pack-out sequence — when you place the order, and confirm the lithium transport packing for your route.
• Shipping documents. Ask which transport documents are issued with the shipment for your destination and incoterm, and whether your freight forwarder needs anything further.
• Payment and terms. Payment terms, currency and incoterm are agreed per order. Confirm them with your sales contact, along with whether any one-time engineering charge applies to a new connector or lead set.

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.
