LiFePo4 vs Lead Acid...Some points of interest.

Agreed!!

What? Diet Coke or water. There is no Pepsi in consideration ;)

Moot Point vs. Mute Point
Moot means unimportant or not worth talking about. Mute means completely silent. Moot and mute might seem like similar words at first glance, but they are pronounced differently. Mute rhymes with cute, whereas moot rhymes with boot. Nevertheless, some people still mishear the phrase moot point as mute point. But don’t let that confuse you. The correct phrase is moot point, not mute point.

YES!! Thank you!

I disagree here, I do agree the Victron is good, but I dont agree they are worth the price. there are so many unit that use the exact same software/hardware out there for less than 1/4 the price. back in the day they used to be the best, not there just riding on there old name and trying to justify prices that are 400% more than they should be.

For example, the problem the engineer in the video you posted is talking about is a problem that doesn't really exist in our application. Also the charge/discharge curve he's using as an example is not nearly as flat as a LiFePo4 curve. The drop off in current is going to be less than the 20% mark where you shouldn't be discharging anyway.

in the discharge curve you wont get a drop in current as the appliance?load is still going to draw the same amount of watts so as the voltage drop you will actualy draw more current untill you hit the point which the battery cant keep up, its usaly dead at that point.

Several capacity tests on LFP batteries have showen this.

For what it's worth,,I have checked the Victron smart shunt against the volt meter on my battery box and the silly cheap plug in meter that goes in a socket,and there all the same,every time I check but only in tenths..

I figured they would be different from everything I've read,but there not...

This is fairly normal, volts-to-volts is pretty simple for a meter to determine, a small discrepancy (particularly with digital displays) in not at all unusual...SOC’s with LFP’s is a bit trickier - this is where you’ll come to appreciate a good SOC meter...Your Victron is one, though I’m sure there are others...

Oh I misunderstood you, Jaycocreek. I thought you meant one of these:

Ever make the effort to discover the set points?

Mine would seem to take lead-acid well below 50% while implying nothing to worry about.

If those are your only specific grievances Sir (curiously deplete of important context...) then I’m completely unaware of any attempts whatsoever to ‘personally malign’ you...

Remarks should be considered within their proper context ...Making such ‘a claim’ shouldn’t be taken lightly, nor does it make it a actual fact - if such was the case, I could then wantonly counter that a ‘cavalier accusation’ made somehow equals a reverse maligning, but admittedly that kinda point for point gamesmanship (as occasionally occurs with a few ‘argument-centric’ forum post) would be plain silliness.... Just my level best opinion only...

Please stop.

Absolutely, once again we are in concurrence....
