Need battery monitor suggestion.

Something like this... any cheap “hall monitor “ will do the job... they do need to be set up..I’ve never used one myself... but seem easy to set up...

Thanks. Found this ones. Says it will work with Lithium Iron Phosphate batteries.
48v Battery Meter, DROK 10-100v Marine RV Battery Capacity Volt Monitor 12v 24v, Lithium Battery Voltage Fahrenheit Temp Indicator Gauge https://a.co/d/cI3ToCo
Or this one:

I think any hall monitor will work.. as long as it’s specs match you’re battery in terms of amp hrs..so 200ah ... I’m no expert though... maybe check the forum to be sure..

Anything that goes by voltage is basically worthless for Lifepo batteries a shunt is the best way
Just having a bit of dinner.. will check them out ASAP

Here’s a couple of examples
Hang on Rodrick.. a lot of these monitors have either an internal or external shunt...so don’t jump the gun...

If they are a shunt type not just a voltage gauge then your good but going off voltage on a Lifepo battery is not going to be accurate

Hall effect type is like a shunt it doesn’t just go off voltage
Agreed.. don’t think Edweather is looking for anything fancy tbh

That first one looks nice and seems popular with some others on the forum.

Love this forum. Never a simple answer.? I always end up with three more questions, as the rabbit holes appear. ? Not sure if I like being reminded of how much I don't know. ? I really appreciate the help.

Thanks. Yes, looks pretty good. Have seen that one. Under consideration, but a bit more than I wanted to spend, jury is still out though. ?

Also in the market looking for one myself also with simple requirements like yourself. Had looked at hall ones too you can see my recent posts on that and seen to be steered away from them due to having lifepo4 and maybe they require some manual intervention to work both ways.

have a good look at the specs of the various DROK, Aili and other Shunt Monitors.
Many now have assorted options such as Bluetooth app, or WIFI and more. Depending on how integrated your system is with software OR if your not there yet but planning to do so, that is worth consideration... nothing worse than having to replace a good item with another because you want an extra function/feature not considered.
WATCH the AMP Ratings ! Realize that the shunt sit's between Batts & Inverter and it MUST be able to take the Maximum Load Potential going through the circuit. Example: a 24V/6000W Low-Frequency Inverter/Charger. That can pull 250A to deliver that 6000W BUT it can surge handle 750A for 18,000W. You'd want a Minimum handling capacity of 300A while 500A would be preferable.
ALSO note that some shunts have bases so you easily mount them somewhere, some do NOT and can be a PITA to mount up somewhere.
NOTE that the DROK & Aili AC Voltage Monitors with Hall Sensor are pretty good and comes in very handy when installed on the AC OUT from Inverter as it goes into your VAC Breaker Panel. You see Volts/Amps/Watts/WattHours and Freq in Hz.
