The Portable LiFePO4 12V 100Ah Battery offers long-lasting power, built-in USB charging for devices, and a high-efficiency charger. Its LiFePO4 chemistry ensures safety, 4,000+ cycles, and stable performance in extreme temperatures. Ideal for RVs, solar systems, and marine use, it combines lightweight design with eco-friendly features, outperforming traditional lead-acid batteries in energy density and lifespan.
How Does LiFePO4 Chemistry Enhance Battery Performance?
LiFePO4 (lithium iron phosphate) batteries provide higher thermal stability, reducing fire risks. They deliver 100% usable capacity, unlike lead-acid’s 50% limit. With 4,000+ deep cycles at 80% discharge, they last 8-10 years. Their flat discharge curve maintains consistent voltage, ensuring optimal device performance until fully depleted.
The crystalline structure of LiFePO4 cathode material minimizes oxygen release during thermal stress, a critical safety advantage over NMC or LCO lithium batteries. This chemistry enables faster ion transfer with minimal resistance, achieving 95% charge efficiency compared to lead-acid’s 75%. Engineers have optimized the nano-scale particle coating to reduce internal impedance by 40% in cold conditions (-20°C), addressing historical limitations of lithium batteries in freezing environments. Third-party testing shows these cells retain 88% capacity after 3,000 cycles at 1C discharge rates, making them suitable for daily deep-cycling applications like off-grid solar systems.

What Are the Advantages of the 12.6V 3A Fast Charger?
The proprietary 12.6V/3A charger achieves 95% efficiency, recharging from 0-100% in 4 hours versus 10+ hours for lead-acid. Its CC/CV (constant current/voltage) algorithm prevents overcharging. Compatibility with solar/wall/generator inputs makes it versatile for field use, with reverse polarity and short-circuit protection.
Advanced temperature compensation in the charger automatically adjusts voltage by ±0.5mV/°C, maintaining optimal charge acceptance across environmental conditions. The three-stage charging profile includes bulk (14.4V), absorption (13.8V), and float (13.2V) modes, precisely tailored for LiFePO4 chemistry. Users can monitor charge status through color-coded LEDs indicating 25% increments. For solar applications, the charger’s maximum power point tracking (MPPT) algorithm extracts 22% more energy from panels compared to PWM controllers. Field tests demonstrate full recharges in 3.8 hours using 400W solar arrays, with automatic input switching between AC and DC power sources without interruption.

FAQs
- Does the BMS prevent over-discharge?
- Yes, the battery disconnects at 10V to protect cells. Manual reset required via charger connection.
- Can I connect multiple batteries in series?
- Up to 4 units in series (48V max) using manufacturer-approved cabling. Parallel connections for 400Ah capacity require balanced charging modules.
- Is the USB output regulated during discharge?
- Yes, dedicated DC-DC converter maintains 5V±2% output even when battery voltage drops to 12V.
