When it comes to battery technology, change may be surprised, especially when shifting from a lead-acid to a lithium iron phosphate battery. However, lithium iron phosphate (LiFePO4) is a fairly stable lithium chemistry when compared to all other lithium chemistries. The battery is made with a cathode material (iron phosphate) that is safe to use. Unlike other lithium chemistries, iron phosphate creates a strong molecular connection, extending cycle life and chemical integrity. Therefore, these batteries have outstanding temperature stability,, high energy density, low self-discharge, fast charging and extended cycle life.

As far as batteries go, lithium-ion ones are rather maintenance-free. The BMS (Battery Management System) automatically performs a "balancing" operation to ensure that all the cells in a battery bank are charged equally. We will assume that the battery is equipped with a BMS, or battery management system, which is common among LiFePO4 batteries supplied in 12/24/48-volt packs. The BMS protects the amperetime battery by disconnecting it when it is discharged or is in danger of being overcharged. The BMS also limits charge and discharge currents, analyses cell temperature (and limits charge/discharge if required) and balances the batteries after each full charge (think of balancing as bringing all the cells inside the battery pack to the same state-of-charge, similar to equalising for a lead-acid battery). Don't buy a battery without a BMS unless you're willing to live on the edge.
Unlike lead-acid batteries, Amperetime lithium batteries are equipped with an integrated Battery Management System (BMS) that prevents the battery from being overcharged. Overcharging lead-acid batteries increases the rate of grid corrosion and shortens the battery's life expectancy.
Are lithium batteries considered safer than other types of batteries? Yes, lithium iron phosphate (LiFePO4) batteries have become the industry best choice for RV, marine, automotive replacement, and general solar PV applications. They are extremely safe, can be mounted indoors, and are an outstanding product for mobile living and entertainment. As with sealed lead acid batteries, you only need to make sure that the cables haven't been shaken loose by vibration when you're on the route and that everything looks good.
A battery bank's depth of discharge (DoD) is the amount of stored energy that may be consumed without significantly shortening the battery bank's life expectancy. For example, under the same condition of 1C discharge, a 100Ah (amp-hour) lead acid battery rated for 50% DoD requires just 1/2 of its rated capacity to be used, leaving the remaining 1/2 in the battery unused.
To offer the same quantity of useful energy, a amperetime lithium battery bank is substantially smaller than a lead-acid battery bank. For instance, if you use 100Ah of energy every day, you will require a 200Ah lead acid battery bank to maintain a 50% depth of discharge, but in amperetime 12v 100Ah battery, only 100Ah of lithium is needed to maintain an 100% depth of discharge. With lithium batteries, that's a substantially smaller battery bank than you'd expect.
Many factors contributed to making LiFePO4 batteries superior. They are absolute lightweights when it comes to weight.LiFePO4 batteries are 60% lighter than lead acid batteries.
When you use your amperetime LiFePO4 battery in a car, this equates to reduced gas use and better mobility. In addition, they are small, allowing you to fit them on an automotive replacement, scooter, a boat, or even an industrial application.
High capacity retention, deep discharge, consistent discharge performance, and Deep cycle lifetimes are required in all the following applications.

Renewable energy sourcesModern boats consume more energy than ever before, not just for the systems that power them, but also for the passengers who bring their own gadgets on board. All of this results in a greater need for battery power. Amperetime LiFePO4 batteries have less space for more power, So, get more batteries that are smaller but have a lot of capacity so that you can have more power.
Amperetime LiFePO4 batteries can also be used to power and charge general-purpose and instrumentation equipment, like computers, amplifiers, mobile phones, scissor lifts, electric lawn mowers, and many types of sensors. They are also safe and environmentally friendly.

I have been torturing myself, trying to develop some sort of a decision tree to see if I should convert to lithium batteries. I have searched the archive for a "lithium for dummies" thread and have come up empty. (If I'm wrong, I am sure someone will let me know!So that is what I am humbly asking for -- is there a really easy to understand site or article that explains or compares lithium batteries to lead/acid batteries for RV use and then guides the shopper through the steps needed to come to a conclusion?Or maybe this thread can serve as a resource for those of us (like me) who do not have technical backgrounds?In any event, here are my particular questions:Aside from the obvious cost difference (which may or may not be a deal killer), my three biggest concerns are weight, capacity, and cold weather charging.Weight: I am in my eighth decade (!) and am having trouble lifting a group 31 lead acid battery without hurting my back. It looks like lithium is a clear winner on that issue.Capacity: I'm satisfied with the capacity of a group 31 -- it's nominally at 110 amp/hours, which means I can get about 55 amp/hours from the battery without risk of damage to the battery. Am I correct in concluding that if I were to get a lithium battery with 100 amp/hour capacity, I could use almost all of that capacity?Cold weather: What does one do about charging a lithium battery when camping in sub-freezing weather? We really like snow camping -- is that a deal killer? We are almost never subjected to temps below ten degrees. And the daytime usually warms up to around 30 or so.Thanks in advance for your help and advice -- and on behalf of all of us dummies, thanks for keeping it as simple as you can!
