LiFePO4 Battery Packs
Solar light battery
Product: 12V 45Ah solar light battery · Model: 26650 4S15P
View data sheetSolar Street Lighting
Rechargeable LiFePO4 battery packs are widely used in solar street lights and energy storage systems, and have a longer cycle life than lead acid battery. The cycle life can be more than 2000 times.
Industry Pain Points
What Goes Wrong Today
- A sealed lead acid block in a pole box loses usable capacity within a season or two of nightly deep cycling
- Pole boxes and buried vaults are a fixed size, so a replacement has to match the footprint
- Winter nights take the pack below zero and summer noon takes the box above 45℃
- Every truck roll to change a battery costs more than the battery
Customer Needs
What Buyers Ask For
- A 12V or 24V pack that fits the existing box and terminal
- A published cycle figure with the DOD condition stated
- Protection that survives a controller fault, not just a healthy charge cycle
- One supplier for the whole voltage ladder, from a 6.4V lamp head pack to a 48V bank

How A Project Runs
The same route for every industry, from the first drawing to the packed carton.
Requirement Analysis
Voltage, run time, peak current, ambient range, enclosure and connector. If the run time is still open we work back from the load and the hours you need.
Chemistry And Cell Selection
LiFePO4 where cycle life leads, lithium ion where energy density leads, lithium polymer where the space is a thin rectangle, Ni-MH where the product is locked to a 1.2V cell size.
Series And Parallel Design
The arrangement sets voltage and capacity. We publish it for every standard pack, for example IFR32700 4S17P for 12V 100Ah, so the comparison is transparent.
Protection And Balancing
Over-charge, over-discharge, over-current and over-temperature protection with internal cell balancing. Communication ports where the system needs them.
Sample And Test
After price confirmation you can request samples to test. Cells and packs are checked against the parameter table published for that model.
Case Wiring And Label
ABS or lead acid style case, aluminium case for e-bike packs, PVC wrap for modules, with your terminal, cable length, connector and logo.
Questions About Solar Street Lighting Batteries
Which voltage should a solar street light pack be?
It follows the lamp and controller. We publish packs at 6.4V, 9.6V, 12.8V and 25.6V, all built from the same LiFePO4 cells, so the choice is a wiring question rather than a sourcing one.
Will the pack survive a freezing night?
Our LiFePO4 packs discharge from -20℃ to 60℃. Charging is specified from 0℃ to 45℃, so the controller should hold off charging below zero.
Can the pack go straight into the existing lead acid box?
The LFP12xx range is built in lead acid style ABS cases with matching footprints and F2, M5, M6 or M8 terminals. Send the case dimension and terminal type you have now.
