Question 1

How big of a lithium battery do I need for RV?

Accepted Answer

Answering this question will require some homework on your part. How much space do you have for a lithium battery in your RV? Do you want to run a couple appliances or all of your appliances? What about RV air conditioners? Power storage is a huge part of your RVs power system, so I would recommend going with as much lithium battery as your budget allows. At the bare minimum, I would go with 100-200 Ah.

Question 2

What brand of lithium battery is best?

Accepted Answer

Again this is all about research. We hope you got enough information in this post to determine that answer for yourself. We have a deal with OKMO Batteries so we suggest buying from them HERE. They are super budget friendly. You can't go wrong with a lithium battery from Epoch Battery, Battle Born Battery or Big Beard Batteries.

Question 3

How long will a 100Ah lithium battery last in RV?

Accepted Answer

The amount of time a 100Ah battery will run will definitely depend on what appliances you are running. Heating appliances will always deplete your lithium battery faster than say a television.
