Thoughts on BMS, Batteryprotect, Shunt based Battery monitor...

[Barold]

I have a Victron BMV 712 battery monitor and really like it - TBH if i redid things i would just but the smart shunt they have now as I rarely use the BMV head to check my batteries. But thinking about LFP, I would be adding a BMS which operates somewhat like shunt that can shut things off. as well as a Battery protect (which I'm considering instead of the BMS. Is this overkill?

One concern i have that favours the Smart BP product over the BMS is that it allows for much thicker (lower gauge) wiring where as the BMS i have has two 10AWG wires soldered to the board. Thoughts?

Battery Protects has some use case limiting factors that you may not be aware of.
They melt when exposed to reverse current.
The also don't like the kind of in-rush current that a big inverter can draw.
That being said I may use one for signalling only in an upcoming project just so I can use a cheaper BMS,
