12.8V 100Ah Long Life LiFePO4 Battery Aluminum Case For Off-Grid Solar Power Supply System
Product Description
This 12.8V 100Ah lithium iron phosphate battery is specifically designed for off-grid solar power supply systems. It overcomes common limitations of ordinary solar batteries such as narrow working temperature range, slow charging speed, and short service life. Featuring a sturdy aluminum alloy housing with stable built-in cell structure, it supports fixed 5A standard/max charge and discharge current for steady low-power solar equipment operation. With fast charging performance and high photoelectric utilization efficiency, plus ultra-wide temperature adaptability from -30℃ to 70℃, it's ideal for long-term unattended outdoor solar monitoring and small off-grid power equipment.
Fast Charging & High Photoelectric Utilization - Optimized internal cell matching improves charging speed and boosts solar energy conversion efficiency for off-grid PV systems.
Ultra-Wide Temperature Working Window - Stable discharge output from -30℃ low temperature up to 70℃ high temperature, suitable for all-season outdoor field deployment.
Constant 5A Stable Charge & Discharge - Uniform 5A rated and maximum current avoids overload risks, perfectly matching low-power solar monitoring equipment load demand.
Extended Long Service Life - LiFePO4 cell material with stable chemical properties effectively slows capacity attenuation to extend the entire pack service cycle.
Intuitive LED Status Indicator - Built-in LED indicator directly displays remaining power and running status for easy daily equipment inspection.

Applications
Outdoor Off-Grid Solar Monitoring Equipment
Existing Shortage: Ordinary batteries cannot discharge normally under extreme low or high outdoor temperature environments.
Solution: Ultra-wide -30℃~70℃ temperature range guarantees continuous power supply for year-round field solar monitoring.
Small Remote Off-Grid Solar Power System
Existing Shortage: Slow charging speed leads to insufficient energy storage under weak sunlight conditions.
Solution: Optimized fast charging design improves solar energy absorption efficiency for limited sunlight areas.
Field Unattended Mini Solar Power Equipment
Existing Shortage: Plastic battery shells deform easily from outdoor vibration and temperature changes.
Solution: Rigid aluminum alloy housing provides good heat dissipation and anti-shock protection for long-term fixed installation.
Low-Power Outdoor Solar Signal Transmission Devices
Existing Shortage: Unstable current output causes abnormal shutdown of low-power solar equipment.
Solution: Fixed 5A constant charge & discharge current maintains steady power output for low-load solar devices.
