LFP batteries are more environmentally friendly: LFP batteries are also more environmentally friendly than other lithium-ion chemistries. This means that LFP batteries can provide more power for a given amount of time, making them ideal for use in applications where high discharge rates are required, such as running an RV's electrical system. LFP batteries have a higher discharge rate: Another advantage of LFP batteries is that they have a higher discharge rate than other lithium-ion chemistries. This makes LFP batteries less likely to cause a fire or explosion, which is important in an RV where flammable materials are present. LFP batteries use iron phosphate as the cathode material, which is less flammable and less likely to cause thermal runaway, a dangerous condition where a battery overheats and catches fire. LFP batteries are safer: LFP batteries are considered to be safer than other lithium-ion chemistries, thanks to their chemical composition. This makes them ideal for use in an RV, where the batteries may be discharged and charged frequently. This is because LFP batteries have a lower rate of capacity loss, which means they can be discharged and charged more times without losing capacity. LFP batteries have a longer lifespan: One of the biggest advantages of LFP batteries is that they have a longer lifespan than other lithium-ion chemistries. Some of the significant reasons why LFP batteries are superior for use in an RV battery bank include: Lithium iron phosphate (LFP) batteries have several advantages over other lithium-ion chemistries, such as lithium cobalt oxide (LCO), nickel manganese cobalt (NMC), and nickel manganese aluminum (NMA). Why LFP Batteries Are the Best Lithium Chemistry for RV Use Victron Lithium Batteries: Part 1 Victron Lithium Batteries: Part 2 The Victron Energy SuperPack lithium batteries include an internal battery management system (BMS), the Victron Energy Smart Lithium batteries use one of the compatible external Victron BMSs (see this BMS Overview sheet). We are very partial to the Victron Energy LFP RV batteries, and these following two videos explain why: their flexibility (internal or external BMS), their ability to withstand extreme temperatures, their communications capabilities, and their solid build. What is the best type of LFP RV battery? This is, of course, a highly-debated question. What is the best type of lithium battery for RV use? Lithium iron phosphate (LiFePO4, a.k.a LFP) is the best type of lithium battery for an RV battery bank: they are not the most energy-dense, but they are not prone to thermal runaway (in fact, they do not catch fire or explode, unlike other lithium types like LCO batteries used in phones and computers), they have long expected lifetimes, and work well as drop-in replacements. Here's a video link that shows the great quality of these batteries - notice the large wire gauges used, the sturdiness of the IP67-rated case, the solidity of the physical pack design, the BMS physically separated from the battery cells, the external heat sink, these are a quality battery.ĭoes everyone need lithium batteries? No - if you are not using any really power-hungry appliances in your RV and thus don't require a very rapid charge rate, you don't need lithium batteries, other types of deep-cycle batteries may work just fine for you. That is typically five times faster than most AGM batteries, the next most advanced battery type. The key advantage of lithium batteries is their ability to accept extremely rapid charge rates - for instance the Relion lithium batteries we sell can be charged at a 1C rate, meaning at 100A for the 12V 100AH battery. Lithium! If you are using power-hungry appliances like the ones listed above, you need to get a lot of power out of your batteries quickly, and then recharge them as quickly as you can. Even the most efficient 12-volt RV air conditioners we sell (like the extremely popular Dometic RTX2000) use so we recommend a minimum battery bank size of 400-600 amp-hours (Ah) if you will be running a 12V RV air conditioner in your camper van. What are deep-cycle batteries? These are batteries whose design is optimized for regular deep discharges of power, perhaps even at very rapid rates by power-hungry appliances like induction cooktops, microwave ovens, RV air conditioners and RV refrigerators. These batteries will provide the dependable power you need under any conditions, something you'll be grateful for at the end of a long road in the middle of nowhere. For an RV, it's essential to have proper deep-cycle batteries for your battery bank.
