1. Ultra-Compact Mini Cuboid & Super Lightweight Tiny footprint of 90*70*101mm perfectly fits narrow internal cavities of solar street light lamp housings and small CCTV camera power boxes. Only 0.6kg weight brings no extra load to outdoor lamp poles, convenient for single-person installation and replacement.
2. Excellent High-Temperature Resistance for Outdoor Scenarios Adopts high-temperature resistant LiFePO4 cell formula, maintains stable charge-discharge performance under long-time direct sunlight and hot summer outdoor environments. No capacity rapid decay compared to traditional lead-acid batteries, greatly reducing outdoor equipment failure rates.
3. Direct Lead-Acid Replacement, Plug-and-Play Upgrade Matches the installation space of mainstream 12V 6Ah sealed lead-acid batteries for solar lights & surveillance cameras. No need to modify lamp housing, charge controller or circuit wiring, realizing simple direct swap to cut maintenance costs.
4. 6000+ Long Deep Cycle Life & Zero Maintenance 6–10 times longer cycle lifespan than equivalent lead-acid batteries; no acid leakage, no electrolyte refilling required. Effectively lowers frequent battery replacement expense for solar street light projects and long-term monitoring equipment operation.
5. Integrated Full-Protection Smart BMS Built-in precision BMS monitors cell voltage, current and temperature in real time. Automatically cut off circuit under abnormal conditions to avoid cell damage, improving whole battery safety and service life for unattended outdoor devices.
6. Complete Global Export Certifications & 24h After-Sales Support Passed CE and RoHS safety testing, fully meets import standards for Europe, Southeast Asia, Africa and Middle East solar & security markets. Our professional after-sales team provides 24-hour online technical support for global customers, solving matching, charging and fault problems efficiently.
