12.8v Lithium Battery Pack 20ah

20AH Capacity & Power Output Provides 20 amp-hours of fully usable capacity (256Wh at 12.8V) with a continuous discharge current of 20A (surge up to 40A for 5 seconds). Powers small 12V devices like LED camping lights, portable fridges, security cameras, and mini inverters (up to 250W) for extended periods-e.g., a 20W load runs ~12 hours on a single charge, ensuring reliable power for weekend camping trips or backup for home gadgets.

LiFePO4 Chemistry for Longevity Built with lithium iron phosphate (LiFePO4) cells, engineered for 3000+ deep cycles at 100% depth of discharge (DoD). Unlike lead-acid batteries (limited to 300-500 cycles at 50% DoD), it retains 80% of original capacity after 8-10 years, drastically reducing replacement frequency. Safe for full discharge without damage, maximizing energy use in scenarios where every watt counts (e.g., remote camping).

Integrated BMS (Battery Management System)

Comprehensive Protection: Guards against overvoltage, undervoltage, overcurrent, short circuits, and thermal runaway, ensuring safe operation in all conditions-critical for portable use near people or equipment.

Cell Balancing: Automatically equalizes cell voltages to prevent imbalance, maintaining consistent performance and extending the pack's lifespan.

Temperature Adaptability: Operates reliably in extreme temperatures (-20°C to 60°C), outperforming standard lithium-ion batteries in cold (e.g., winter camping) or hot (e.g., desert hikes) environments.

Ultra-Compact & Lightweight Design Weighs only 2.5-3kg (70-80% lighter than a 20AH lead-acid battery, which weighs 8-10kg) and features a slim profile (e.g., 18cm x 10cm x 15cm). Easily fits in backpacks, RV storage compartments, or marine tool kits, making it ideal for portable applications where space and weight are critical.

 

 

 

 

 

 

 

 

 

 

 

 

 

FAQ

Q: How does the pulsed electric field treatment enhance material properties?
A: When we apply a pulsed electric field to materials, it triggers a series of molecular-level changes that enhance their properties. In polymers, for example, the pulsed electric field can align the molecular chains. Normally, polymer chains are randomly oriented, but under the influence of the electric field pulses, they tend to line up in the direction of the field. This alignment improves the mechanical strength of the polymer, making it more resistant to stretching and tearing. It also enhances the electrical conductivity as the aligned chains provide a more favorable pathway for electron movement. In food processing, the pulsed electric field can be used to pasteurize liquids without heating. The electric field pulses disrupt the cell membranes of microorganisms, killing them while preserving the nutritional value of the food. In biomaterials, it can enhance the growth and differentiation of cells. The electric field can influence the behavior of cells by changing the microenvironment around them, opening up possibilities for tissue engineering, such as promoting the growth of bone cells on a scaffold material.
