LiFePO4 and AGM batteries serve the same deep-cycle jobs, but lithium wins on usable capacity, weight, lifespan, and cost per cycle, while AGM wins on upfront price and compatibility with older charging systems. This guide compares the two chemistries across real-world RV, solar, and marine use so you can choose with your eyes open. How … Read more
A fully charged 12V 100Ah LiFePO4 battery reads about 14.2-14.6V during charging and settles to 13.2-13.6V at rest, which is the true “full” voltage. Because lithium has a flat discharge curve, voltage alone cannot tell you the state of charge accurately, so a battery monitor or Bluetooth BMS is the right tool. This guide explains … Read more
You do not need to charge a LiFePO4 battery to 100% for daily use, and in fact keeping it between 20% and 90% extends its life. Charge to 100% only before long storage or a full-capacity test, then use the battery normally. This guide explains the science, the practical routine, and how to manage charge … Read more
LiFePO4 batteries degrade very slowly when not used, losing only a few percent of capacity per year when stored correctly. The key is how you store them: charge to 50-80%, disconnect loads, and keep the battery cool and above freezing. This guide explains the science of lithium storage, what happens if you ignore the rules, … Read more
LiFePO4 and standard lithium-ion are both lithium batteries, but they serve different jobs: LiFePO4 wins for deep-cycle, safety, and lifespan, while standard lithium-ion (NMC) wins for energy density in phones, laptops, and EVs. This guide compares the two across capacity, lifespan, safety, and cost so you can pick the right chemistry. What Are the Key … Read more
Yes, lithium LiFePO4 batteries are good, and for deep-cycle applications they are the best practical choice on the market: 100% usable capacity, 4,000-8,000 cycles, half the weight of lead-acid, and a decade of service. This guide explains the advantages of lithium iron phosphate technology, what it costs, and where it falls short. What Are the … Read more
A 100Ah lithium battery can power a surprising amount of gear: a 12V fridge for 18-28 hours, a CPAP for two nights, a laptop and phones for days, or a 1,200W inverter briefly. This guide walks through real-world runtimes for common devices, the math for your own loads, and the limits you should respect. How … Read more
The right lithium battery size for camping depends on your daily watt-hours: 100Ah covers a weekend of fridge, lights, and devices; 200Ah suits full-time use and inverter loads; 300-400Ah powers electric cooking and heavy setups. This guide explains how to calculate your own number and choose between 12V, 24V, and 48V. How Do You Calculate … Read more
LiFePO4 batteries last 8-15 years with daily cycling, and the number depends more on your charging habits and temperature than on the brand. A pack rated for 4,000-6,000 cycles at 80% depth of discharge delivers 11-16 years of one-cycle-per-day service. This guide explains the cycle math, real-world variables, and how to make your battery last … Read more
Several battery technologies are positioned to challenge or replace lithium-ion: solid-state, sodium-ion, lithium-sulfur, lithium-iron-phosphate (LiFePO4), sodium-sulfur, flow batteries, and graphene-enhanced cells. In 2026, only LiFePO4 is widely commercial today, while solid-state and sodium-ion are the most promising near-term successors. This guide explains each technology, what it promises, and when it might actually arrive. Which New … Read more
LiFePO4 batteries last the longest of the lithium chemistries for deep-cycle use, with 4,000-8,000 cycles or 8-15 years of service, because the iron phosphate cathode is chemically stable and tolerates deep discharge. NMC lithium-ion lasts 500-2,000 cycles and is better suited to electronics, while lead-acid lasts only 500-1,000 cycles. This guide explains why LiFePO4 wins … Read more
PowerStar LiFePO4 batteries are advanced lithium iron phosphate power sources designed for RVs, solar storage, marine systems, and off-grid homes. They deliver about 1,280Wh in a 12V 100Ah pack, support 4,000-6,000 charge cycles, and weigh roughly half of an equivalent lead-acid battery. This guide covers performance, benefits, charging, safety, and the best applications so you … Read more
