What Advertising & Signage Solar Light Covers
For procurement decision-makers, what's expensive isn't the battery — it's replacement cost: ¥1,500/visit lift + traffic police + work permits. 3 replacements in 5 years = ¥4,500 labor — 20× battery cost. PLB signage version: small capacity long life + 5-year zero maintenance, 95% 5-year total cost savings.
Professional Battery Solutions
95% 95% Cost Savings — The Key is Maintenance Cost
Sign lights only 5–15W, battery ¥50/piece seems cheap. But at 6-10m height or roadsides/mountain tops — hidden replacement cost is staggering: ¥1,500 lift + traffic police coordination + work permits. 3 replacements = ¥4,500 labor. Battery ¥200 + labor ¥4,500 = ¥4,700/lamp/5yr. Maintenance cost is 22.5× battery cost.
PLB small capacity 5-year zero maintenance: ¥80/lamp total (battery + 1 shipping) vs lead-acid ¥4,700/lamp (battery + 3 replacements), saving 98%. Higher/remote installation = more savings. For signage contractors — most direct bidding advantage.

Ultra-Compact — Hidden Inside Sign Structure
The pain is specific: Ultra-Compact — Hidden Inside Sign Structure In daily operation, lead-acid or manually managed packs lose capacity between scheduled checks, maintenance teams cannot inspect every unit, and the failure surfaces only when the load is already at risk.
PLB signage version 30-40% smaller volume. PLB's LiFePO₄ pack and BMS monitor cell voltage, temperature and SOC continuously, alert before a weak cell becomes a failure, and are sized to the application's load profile.

Solution Advantages
98% Cost Savings
¥80 vs ¥4,700 per lamp/5yr
Five years maintenance-free brings the total cost to ¥80 against ¥4,700 for lead-acid: maintenance, not the battery, is where the money goes.
Zero replacement in five years · The higher and more remote, the more you saveUltra-Compact
30-40% smaller, Φ20mm min
High-energy-density cells shrink the pack by 30–40% in three enclosure formats, down to Φ20 mm, so it hides completely inside the sign.

Frequently Asked Questions
The questions lighting contractors and municipal buyers ask most about LiFePO₄ solar-lighting batteries in the Advertising & Signage scenario — 12 h (all-year lighting), and what it takes to qualify.
Which pack fits the Advertising & Signage luminaire already in service?
The same capacity fits in 30–40% less volume, with cylindrical, prismatic and pouch formats and five-day custom sampling, so the pack goes inside the luminaire. Typical models for Advertising & Signage builds are LL-SL-SIGN5 and LL-SL-SIGN10.
How much usable capacity does the pack deliver across a night in Advertising & Signage service?
The pack is rated 3,000–5,000 cycles with 80%+ capacity retention, which covers a five to eight year design life without replacement.
Will the pack survive Advertising & Signage conditions for its full service life?
Wide-temperature cells cover −30 °C to 65 °C, and the sealed housing resists UV and moisture. Endurance: 12 h (all-year lighting).
How does the pack connect to the charger and control system in the Advertising & Signage scenario?
The BMS reports SOC and cycle data, with 4G cloud monitoring available for fleet-level management.
Can the pack be customized for the Advertising & Signage application and certification file?
Cells, BMS, housing, terminals and nameplate are customizable. Custom samples take five working days. Tell us the luminaire wattage, daily lighting hours and installation latitude — our engineers size the pack and recommend the matching model within 24 hours.
