Understanding Lithium-Ion & LiFePO4 Technology

What are Lithium-Ion Batteries?
Lithium-ion batteries are advanced rechargeable batteries known for their high energy density, lack of memory effect, and slow self-discharge rate. They are a superior alternative to lead-acid batteries, offering lighter weight, higher open circuit voltage, and efficient power transfer.

What are LiFePO4 (Lithium Iron Phosphate) Batteries?
LiFePO4 batteries are a specific chemistry of lithium-ion batteries that stand out for their superior thermal and chemical stability, enhanced safety, and remarkable cycle life (often exceeding 2,000 charge cycles). Himax primarily focuses on designing and manufacturing LiFePO4 batteries for our deep cycle and starter battery lines due to these inherent advantages.

Himax Deep Cycle Lithium-Ion Batteries: Unmatched Advantages

Choosing Himax 12V 300Ah Lithium Deep Cycle Battery means investing in cutting-edge technology:

Substantially Lighter: A fraction of the weight of lead-acid, perfect for RV, marine, and portable power solutions.
More Powerful: Consistent higher voltage output for longer durations, even at lower capacities.
Low Self-Discharge Rate: Less than 3% charge loss per month, ideal for long-term storage without worry.
Fast Recharging: Accepts charge current at up to 5 times faster than a lead-acid battery, with 97% charge efficiency.

Himax Deep Cycle Battery Advantages Over Competitors

Our innovation sets us apart:

Internal Cell Balancing Circuit: Microprocessor-controlled for maximum cell performance.
Advanced Battery Management System (BMS): Prevents overcharging/discharging, ensuring safety and extended lifespan.
Quality Engineering & Prismatic Cells: We utilize the highest quality components and prismatic cells, allowing for optimal design, better thermal management, and a perfect drop-in fit for most vehicles and applications.

Capacity (Ah) Comparison: Himax Lithium vs. Lead-Acid

A Himax 12V 300Ah LiFePO4 Battery provides its true rated capacity at a 1C discharge rate meaning a 300Ah Himax battery can deliver 300A for 1 hour. In contrast, a lead-acid battery with a “20hr” or “25hr” rating will offer significantly less usable energy at higher discharge rates, and cannot be safely discharged below 50% Depth of Discharge (DOD) without damage. Himax lithium batteries can be safely discharged to 90% DOD, effectively making a 12V 300Ah Lithium Battery comparable to a much larger lead-acid battery for real-world usage and long cycle life battery performance.
