Best RV Battery Box: Top Picks and Reviews

Could you imagine getting ready to get your trailer ready for a trip and you go to turn on the cabin lights but get nothing. You check the batteries and find that they have been stolen.

One of the biggest reasons for getting a battery box is to be able to keep your batteries in a location where they have plenty of ventilation.

They also need to be in a spot where they can be locked up, making it more difficult for would be thieves to steal them.

Some 5th wheels or travel trailers will come with a 12VDC battery and the box is only big enough to handle one. Many long term RV?ers prefer having 2 deep cycle 6 VDC batteries setup in series because they last longer.

If you?re in the same boat, er RV, then retrofitting a battery box that?s big enough for both would be ideal. These are called a dual battery box.

When you?re looking for the battery box, just remember to find one that has ventilation for the batteries. This will allow unwanted gasses to escape.

Another thing to check for is to make sure the battery box has weep holes or holes in the bottom to allow fluid to properly drain. If yours doesn?t come with one, you can create weep holes by drilling in the bottom of the box.
