Lithium Ion RV Batteries

[philo111]

Except for the price......Are Lithium Ion RV Batteries the BEST alternative for Coach Batteries?

I would expand on this comment to say that LiFePO4 batteries do require the user to be aware of the temperatures in which the batteries will be used. They discharge well in below freezing weather but they get damaged if they are charged when the battery itself is below freezing. Also, they get damaged if the battery itself gets above 140 F. So you put in a BMS and intersperse heaters within the well-insulated battery compartment to maintain the temp above 32 and you are all set.

I'd jump in here but I don't want to get sassed at.

I'd be using them the same way you do.

You have no idea how I use my batteries. Do you boondock? Do you power AC appliances from the batteries with an inverter? Do you have a residential refrigerator?

By far the majority of all RV owners never camp without electrical hookups. In that situation, just about any cheap battery is sufficient.

Amen ... to all that!

From the few Forum members that have them and have posted about them, the Lion batteries are very good for RV's, especially if you have a sophisticated electrical system. They save a lot of weight so that can also be an advantage. Price is a big turn-off.

A very interesting technology that I was not aware of ... but they are Gawd awful expensive.... my new top of the line Lifeline AGM batteries of equivalent capacity are about 1/3 the price.

Whats wrong with what we got ? Ninety nine point nine percent of us get along just fine with what came with the RV . Unless ya maybe just like to throw money away .

[time2roll]

Yes IMO.
