The integrated BMS monitors and helps maintain your lithium battery, eliminating the need to do this yourself. Even if you follow this conservative rule of thumb, a 100 amp-hour lithium battery provides about 80 amp-hours before it needing to be recharged. However, most people don’t deplete them below 20% before recharging. This limits its future capacity and lifespan.īy contrast, you can discharge a lithium battery almost completely without causing damage. That means that if a lead-acid battery is rated at 100 amp-hours, you only have about 50 amp-hours of usable energy before you start damaging the battery. You can only safely discharge a lead-acid battery to about 50% of its capacity rating before you start to damage the battery. More Battery CapacityĪnother advantage to lithium batteries is that they have a greater useable capacity as compared to lead-acid batteries. This adds to not only increased safety for the user but the environment as well. Lead-acid batteries are also susceptible to damage and overheating when being charged and discharged but do not have a BMS to help protect them.Īdditionally, LiFePO4 batteries are made out of non-toxic materials that resist thermal runaway. Lithium batteries typically have an integrated battery management system (BMS) which helps them charge and operate more efficiently and safely. Safer than Lead Acid or AGMĪlthough most lead-acid or AGM batteries are sealed to improve their safety, they still do not offer many safety features that lithium batteries do. However, lithium batteries can last up to ten times longer than a standard lead-acid battery which often results in overall cost savings over time. Some people balk at the up-front price tag on lithium batteries, which can easily reach $1,000 each. However, many other benefits help make LiFePO4 batteries the optimal choice for RVers. The safety consideration of LiFePO4 batteries is obviously essential. Therefore, you can dispose of it more easily than lead-acid and Li-ion batteries. LiFePO4 batteries have a lower energy density than Li-ion batteries, resulting in them being more stable and making them an excellent option for RV applications.Īnother safety benefit of the LiFePO4 is that lithium iron phosphate is not toxic. The Safest Lithium Battery: The LiFePO4Īs we mentioned earlier, the most popular option for lithium RV batteries is the lithium iron phosphate (LiFePO4) battery. As this technology has advanced, improvements such as integrated battery management systems (BMS) and more stable internal chemistries have resulted in lithium batteries that are safer than their lead-acid counterparts and provide many advantages. Lithium battery technology is still relatively new. Thermal runaway can happen in all types of batteries, not just lithium, and can be caused by many different factors. ![]() These accidents have given lithium batteries a bit of a bad reputation for being unsafe.īattery fires and explosions like this are caused by thermal runaway. Lithium-ion batteries have been in the media in the past few years for incidents where cell phone batteries catch fire or explode on airplanes or perhaps an electric car catching on fire. However, when used and maintained correctly, lithium batteries of all kinds can be safe. Some are safer and more stable than others. Are Lithium Batteries Safe?Īs we mentioned above, there are many different types of lithium batteries. The most common lithium battery replacement for lead-acid batteries is the lithium iron phosphate (LiFePO4) battery. However, in this article, we discuss lithium battery replacements for traditional lead-acid batteries in RVs, boats and other larger mobile off-grid applications. Phones, computers, and other small rechargeable electronics commonly use Li-ion batteries. For example, you’ve probably heard of lithium-ion (Li-ion) batteries. There are many different types of lithium batteries. Learn More: The Truth About Lead-Acid Vs. Compare this to traditional lead-acid batteries, like in your car, which uses lead as the lead dioxide. Lithium batteries get their name because they use lithium metal as the cathode material. When you connect an electronic device to a battery, electrons flow from the anode to the cathode through your device and power it. Batteries have a positive side (cathode) and a negative side (anode). There’s A Reason Lithium Is The New Gold Standardīefore diving into what a lithium battery is, let’s cover the basics of how a battery works.The Safest Lithium Battery: The LiFePO4.
