The LB07 is a two-cell LiFePO4 pack built for low-voltage lighting equipment: 6.4V nominal, 3.6 Ah and 23.04 Wh of usable energy in a compact PVC-wrapped block supplied with the connector your luminaire needs. It is designed to sit inside the fixture and be forgotten about, not to be checked and topped up on a service round.
As a 6.4V 3.6Ah LiFePO4 lighting battery, it suits fittings where steady output and a sealed, maintenance-free block matter more than a familiar chemistry. LiFePO4 holds its voltage across most of the discharge, so the light stays bright until the pack is close to empty instead of fading gradually. There is no electrolyte to top up and no terminal corrosion to clean inside a sealed head.
Most projects that begin with a 6.4V battery pack for emergency lights are replacing a lead-acid block that has turned into a maintenance item. The pack fits the same kind of compartment, but the charger and the driver still have to suit lithium chemistry, and that check is what decides whether the swap works.
We are a battery pack producer, and we build this pack for lighting OEMs and brand owners, for contractors keeping a specific fitting in service, and for distributors who need the same pack order after order. Every order runs from an approved drawing and the current specification revision, and we confirm that drawing against your luminaire before a sample is released.

The pack's discharge current is 3600 mA. Shorter documents round the same rating to 3 A; it is one figure written two ways, so work from the revision printed on the drawing you are approving rather than from a remembered number.
That figure is a rating, not an instruction to run the pack flat out. Drawing 3600 mA from a 3.6 Ah pack is close to a 1C rate, and at that level the pack gives up a noticeable share of its nominal capacity and runs warmer than it would at a lighter load. Lighting loads usually pull a fraction of that — a few hundred milliamps for a modern LED head — so a 6.4V battery pack for emergency lights spends most of a shift well inside its limit.
Set the luminaire to disconnect before the pack reaches its end-of-discharge point. The driver's low-voltage cut-off should sit above that floor, and an emergency controller should read the last part of the curve as a low-battery condition rather than trying to extract the final milliamps.
If the fixture has a start-up surge, such as a large capacitor on the driver input, describe it with its duration. A short peak and a continuous draw are handled differently, and the drawing should state which applies to your configuration.
Ask for the approved continuous discharge rating for your revision together with the temperature at which it was measured. A figure quoted on a bench at room temperature does not describe a pack sealed inside a warm head.
Keep each 6.4V battery pack for emergency lights in its original packing until it is needed, in a dry place out of direct sun. The storage range in the table is a survival window rather than a recommendation; a cool, stable store room is always the better home for lithium cells.
Packs that will sit for months are normally held at part charge rather than full or empty. Ask us for the storage state of charge and the recharge interval that apply to this model, and mark the date on the box so the interval is not missed.
Bring a cold pack up to room temperature before you open its bag. Condensation on the terminals and the connector is a common cause of a pack that behaves oddly on first use, especially where stock moves between an air-conditioned store and a warm production floor.
Never let the leads touch each other or a metal bench, and keep the connector protected while the pack waits. Do not stack heavy items on the wrap, pierce it, or use the pack as a support while the luminaire is being assembled.
Inspect each pack on receipt: wrap intact, leads undamaged, connector clean, label legible and matching the revision you ordered. At end of life, send the pack to a battery collection or recycling service rather than general waste, and tell the service the chemistry and condition so it can advise on handling.
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 powers low-voltage lighting and backup equipment: exit signs and maintained emergency luminaires, solar path and garden lights, rechargeable work lights and inspection lamps, and small backup units where a 6.4V rail feeds the driver. In every case the pack is the energy store behind a driver, so the application decides the current, the runtime and the connector rather than the other way round.
Yes. The connector is built to customer requirements, so send the mating part number, pin numbering, polarity, lead length and cable route, and the pack is made to that interface. The agreed interface is then shown on the drawing and locked into the specification revision before the sample is approved.
The specification gives a 7.2V charging voltage with a 720 mA standard charge current and an 1800 mA maximum. Set the charger to the standard figure for normal use, and treat 1800 mA as a ceiling that applies only under the conditions stated for the selected configuration. Confirm the charging specification for your revision before you fix the charger's settings.
It can sit inside outdoor and solar luminaires, but the pack itself carries no IP rating — protection comes from the housing around it. Assess the enclosure for water entry, condensation and the temperature the pack will reach in sun, and check that the solar controller's profile matches the charging voltage listed here.
The specification gives a design life of 5 years at 55 °C. That is a design condition rather than a warranty or a measured lifetime in your fitting: real life depends on the temperature inside the enclosure, how deep each discharge runs and the charging profile. Ask us for the test basis behind the figure and validate a sample under your own duty cycle.
Protection functions and their thresholds are agreed for the selected configuration and shown on the drawing, so confirm them for the revision you are evaluating rather than assuming a standard circuit. If your luminaire depends on the pack for over-discharge protection, say so in the brief and the requirement goes into the specification.
Sometimes, but the circuit has to be checked first. It often fits the compartment that held a lead-acid block, yet the charger profile, the driver's low-voltage cut-off and the connector all have to suit lithium chemistry. Send the label from the old pack, the charger details and a photo of the connector, and we will tell you what has to change.
