Buying Guide (What to look for in your ideal Battery Disconnect Switch for RV)

From how to install a battery disconnect switch to its application, getting one for your RV can be pretty tedious. There are numerous variants available for a battery disconnect switch; hence you must consider the following aspect while purchasing the same for your RV.

Manual vs Automatic

An automatic battery disconnect switch will save you time and hassle in the long run because it automatically shuts off power when the vehicle is disconnected from the power source. A manual battery disconnect switch RV makes it possible to turn off the power with just one switch manually, but this comes at the cost of more time and effort than an automatic switch does. Manual switches are cheaper but require human intervention, which may not be convenient for some people.

Battery Size

Most battery disconnect switch models can accommodate two or more batteries. If you have a larger RV, then you might need one with multiple outlets for your batteries. Make sure that the battery disconnect switch RV is compatible with your battery size, has a suitable power rating, and can be easily installed.

Voltage and Amperage Rating

Material and Durability
