How much battery information is enough?

[BouncyBoatFolk]

Hi, so after taking the black Friday plunge my Lithium 280A/H battery arrived. Prompt dispatch from Fogstar. I've notionally set up the app on my phone and was very pleasantly surprised at the amount of data viewable. This is compared to the current AGM battery read by on board low tech Volts reading only. The phone App shows volts, A/H levels. The history. The amount of power used, and remaining. I've been opening and closing the app frequently, and it's always loaded seamlessly. As a further B.F. deal I ordered a 500A Smart Shunt. I'm now wondering if this is surplus to my requirements. I'm already seeing far more informative data than I thought I would get, and It's quite comprehensive.
Prompting the question, do I still need to fit the smart shunt? What extra resource is that bringing to the lithium party?
I'll also be splicing a Lithium charger into hab system as well.
T.I.A.
Mike.

I have a simple way of checking battery capacity p, if the telly goes off (pub) if the light goes off (pub) worked fine for years.

I've been the same for years. But after some issues I fancy a way of seeing what's going on.
I didn't know my B 2 B had stopped working, and that leaving the hab electrics on also left the head unit on standby. The head unit was drawing over an amp on standby.
Plus a monitor will give me something else to worry about.

Agree I fitted a BMV712 for the programmable relay the display is in my double floor.

Mine is in the battery box with the solar controllers. What do you use it to switch, on which function, temp, voltage, SOC?

Not ready to set it up yet for my needs but I will be using percentage SOC as voltage is meaningless with Lithium.

I use SOC to control charging of battery and then different programs for different purposes. ie longterm storage, ready, full use
