For compact emergency and solar lighting fixtures, this 3.2V 3.2Ah LiFePO4 pack provides a sealed, rechargeable low-voltage source in a format built for small lamp housings. As a 3.2V battery pack for emergency lighting, it is used by OEM fixture makers and industrial equipment suppliers in exit heads, garden and street luminaires, portable flashlights and small backup units. It replaces Ni-Cd, Ni-MH and lead-acid blocks only where the charger, compartment and connector are matched to the new pack. Automated assembly and electrical inspection help keep capacity, voltage and discharge behaviour consistent from one order to the next. Confirm the LED driver window, charge profile, connector polarity and available space before approving a sample. Buyers usually arrive looking for a 3.2V 3.2Ah LiFePO4 battery, a 3.2V lithium iron phosphate battery or a rechargeable LiFePO4 battery pack, and they want a manufacturer or supplier who can handle custom packs, OEM production and orders shipped from China. The same pack is commonly sourced as an emergency light battery, a solar light rechargeable battery, a backup power battery pack and an industrial rechargeable battery, so tell us which of these matches your product and we will confirm the right configuration with you.
Automated assembly is what allows a lighting OEM to place a repeat order without treating every batch as a new project. Cells are selected and matched before pack assembly; automated stations handle the repeatable mechanical steps; electrical checks screen voltage, capacity and resistance; and production batches are kept identifiable. The line handles both standard lighting packs and customer-specific builds, so a change in connector or lead length stays inside the same quality process. For volume programmes, this is the difference between a sample that works and a shipment that behaves the same way. Before production, agree the inspection criteria and the sample acceptance plan for your fixture.
Lighting loads are sensitive to voltage sag. In this 3.2V battery pack for emergency lighting, a low-resistance cell structure reduces energy lost as heat inside the pack, so more of the stored energy reaches the LED driver. In practice, that means the lamp holds a steadier output through the discharge curve and is less likely to flicker or drop out as the pack approaches the end of a run. The effect matters most in fixtures that operate continuously for long periods, such as emergency heads during a power failure or solar lamps through the night. Pair the pack with a driver whose input window and cutoff behaviour match the nominal voltage and cut-off. If the fixture draws short current peaks, share those peaks with our engineers so the protection board and connector are reviewed together.
LiFePO4 chemistry is chosen for lighting packs that are expected to sit in a fixture for years, not months. Its cycle performance reduces how often a building manager has to schedule battery replacements, and the sealed pack removes the water topping and terminal cleaning that lead-acid blocks need. The materials contain no cadmium or lead, which simplifies environmental discussions for OEM programmes, and end-of-life packs should go through a battery collection route rather than general waste. For projects with a defined service window, ask for the cycle-life test conditions and the capacity-retention threshold that apply to the exact configuration. The stated design life depends on working temperature, so keep the installed environment inside the published limits.

Lighting packs fail projects for small reasons: a connector that does not mate, a charger that holds the pack at the wrong voltage, or a batch that drifts after the first sample. Surlon Power has spent 17+ years building battery packs for emergency lighting, solar storage, industrial equipment and backup power, and that track record shapes how we handle every lighting inquiry. We start with your fixture: LED driver window, normal and start-up current, required runtime, compartment drawing, charger and connector. From there we specify the pack, produce samples and check them before a production order. We operate automated production bases, maintain an independent R&D team, hold multiple technical patents and work to international quality systems. If you are weighing a low-voltage lighting pack, what counts is a supplier that keeps the same build, documents and communication in place from sample to repeat shipment.
On drawings, purchase orders and packing labels, the same pack may be written as a 3.2V 3.2Ah LiFePO4 battery pack, an emergency light battery, a solar light battery or a rechargeable lithium battery pack. Those names describe the same compact lighting cell, but they do not carry the connector or capacity details your line needs. Add the pack drawing revision, connector type, lead length, polarity and item description to the order line. If your ERP uses a supplier code, send it with the drawing so the label and the technical file match. This avoids a situation where the right pack arrives under a name the receiving team does not recognize.
Projects that outgrow a compact lighting pack often move to a larger pack or a separate protection board. The 12.8V 100Ah SLA replacement battery suits larger backup and solar storage work; the ESS 16S100A and 16S200A BMS boards support 48V pack designs at different current classes; and the 4S150A BMS is used in 12V-class packs. These are separate products, not accessories for the lighting pack, so match voltage, current and enclosure before combining them in a system.
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.
It is built for compact low-voltage lighting: emergency exit heads, wall and ceiling emergency lights, solar garden and landscape luminaires, portable flashlights and small industrial backup fixtures. The pack suits designs where a single LiFePO4 cell can meet the load and the charger is set for a 3.2V nominal battery. Confirm the LED driver window and required runtime before selecting it.
Only after the charger, connector, compartment and cut-off behaviour are checked. A 3.2V label alone does not make a replacement safe, because the old charger may have a different termination method and the lamp may expect a different discharge curve. Share the old battery's printed details and the charger model, then validate a sample in the actual fixture.
Use a charger set for the stated 3.65V charge voltage and 640mA standard charge current, with the correct termination for the pack. The specification also lists a 640mA trickle current and a 2.5V cut-off. If you are keeping an existing charger, have its profile reviewed against the pack before installation.
Low resistance means less energy is lost inside the pack as heat, so the LED driver receives a steadier supply through the discharge. In practice, the lamp is less likely to flicker or drop out near the end of a run. The exact resistance figure is listed with the specifications; the benefit still depends on the driver and wiring.
Yes. Connector type, pinout, polarity, lead length and internal layout can be specified around your luminaire drawing. If the standard build is close but not exact, we can review a custom LiFePO4 battery with your engineering team.
Keep it dry, within the stated storage temperature range, and away from loose metal that could bridge the terminals. Do not leave a pack in a hot vehicle or direct sun. Ask us for the recommended storage state of charge and recharge interval for the exact configuration before putting it on a shelf for an extended period.
That brief supports a much larger capacity than this 3.2Ah lighting pack. Start from the load, required runtime and available compartment, then ask us to review the right configuration. A larger pack may need a different charger, connector and enclosure, so do not treat the capacity label alone as a drop-in match.
The pack is built with a protection board that addresses overcharge, over-discharge, short circuit, over-current and overheating. Ask for the protection specification for the exact revision you are approving, because the board and thresholds must match the charger and load.
