Battery options

I like that battery monitor but could not find detail information. Do you know if it was manufactured in Australia?

Judging from the wording in the description I would say they are made in China.

I don’t know where it’s manufactured.

It’s very useful to monitor battery voltage and look at a graph of voltage over time while the app is active. The display showing % of charge and charging is useless but being able to remotely monitor battery voltage is more than worth the $29.95 price.

Until I installed it I didn’t realize that the way the disc brake installers wired my system the rv battery was slowly dropping voltage while being towed and refrigerator was on. After a 6 hour trip my RV battery voltage dropped to below 11 volts which could have caused dangerous braking issue.

The Brakerite install manual had you wire the Brakerite actuator’s very low charge current to charge the battery rather than using the truck’s alternator to supply battery charge. I rewired it using performance trailer braking modified wire diagram and now it’s charging as expected. https://performancetrailerbraking.co...ng-diagram.pdf

Without the monitor I would never have known.

Should I get the exact same battery or same type? In other words It is an Interstate SRM-24. I see other brands that are SRM-24. Or is it a naming thing that doesn't really tell you much?

The same type, FLA or AGM

The same type, FLA or AGM

Oh so I could in theory do any of the Lead acid batteries. Like one with more capacity?

yes, two different Ah batteries in parallel you add the Ah together.

Just make sure they are the same voltage and battery type. Such as two 12vdc AGM batteries. Manufacturer and Ah can be different



EDIT: remove incorrect information.

That may apply to series configuration. Not so certain about parallel.

BAH! I know better than to try to think when I'm tired!

With parallel batteries, it INCREASES the total available Ah. So if you have a 65 Ah battery and a 80Ah battery in parallel, you have effectively 145 Ah available.

Wow. Sorry for the bad information previously!

EDIT: corrected incorrect information.

That's voltage and current provision, I'm speaking just on the amp hour rating.

Ok, that battery says 81 Amp Hours so get 81AH FLA. Got it

I corrected my statement, which was wrong.
