House Battery Questions

We recently purchased a 2019 Big Horn Traveler. We are pretty sure the house batteries that were installed when we originally looked at it were swapped out with some not so great ones.
We can't find a lot of information on the brand that is there now. It's RoadHawk.
We are wondering what is the best battery for the rig? We don't dry camp a lot but like to be able to count on the battery, which died after very little usage this weekend.
Also is it possible to add 3 batteries?

Thanks a lot!

Hi dalezcar,

Congratulations on the new Bighorn and welcome to the Heartland Owners Forum.

If your batteries died while plugged into shore power, they're probably not getting a charge. If you have auto-levelup, while on shore power, cycle the control panel to show DC voltage. On shore power, it should read at least 13.2V DC. If it's less than 13V, there's a problem getting the output of the Power Converter to the batteries.

Inside the coach, you have a control panel that displays holding tank levels, and battery level. While on shore power, you should have 4 lights illuminated. If not, you may have a problem with the Power Converter.

Check the 120V AC main breaker panel - flips the breakers off and back on to see if you get 4 lights. If not, you'll have to check the Power Converter is actually plugged in to its outlet. If it's wiggled out, plug it back and tie it in place. The Power Converter is probably located behind the rear wall of the pass through basement storage.

If the Power Converter is plugged in, check the 3 on-board blade-type fuses located on the Power Converter. If someone changed out the batteries, and momentarily connected them backwards, the fuses will blow and need to be replaced.

We have several owner-written guides that you may find helpful in running down a problem: Electrical User Guide is here, and 12V Block Diagram and Diagnostic guide is here.

Since you have a 2019 you probably don't have the level up panel Dan is referencing. More likely you have a consolidated small touch panel that displays the tank levels and battery info. Just touch it and it should give you the voltage level (you can also meter the batteries to determine the voltage). Then follow what Dan said. The other thing to check is the DC circuit breaker between the batteries and converter. There is a tiny button on one end that can be used to reset the breaker if it is blown. It is the only breaker with a button.
