Converting to LiFePO4

Does anyone do fire suppression for the batteries, just curious what not to do so there is no fire,  asking because, my neighbors house just burned down due to a lipo Flashlight charger, 

I keep my coach plugged in all the time on the side of the house, would you still do that or what is the dues and donts of these batteries,

That battery was not a lithium iron phosphate that was a cheap Chinese lithium ion battery. Totally different chemistry and the chances of a runaway heat cycle on Phosphate are next to zero.

Okay, trying to get as much knowledge and info to make sure I do this right.

I just ordered 3 of these Li Time 12V 230AH batteries

https://www.litime.com/products/litime-12v-230ah-plus-lifepo4-battery-built-in-200a-bms-max-2944wh-energy

To replace my 8 full river 224AH 6V batteries... that were in my motorhome. If I am doing my math correctly, my 6 volts wired in Parallel provided 896AH of 12V juice at , but since they were AGM batteries, and really should not get below... that gave me 448AH of juice (896/2).  The new Lithium batteries are 230AH X 3 = 690AH of 12V juice... and since these can be ran down to zero.... that is a little over a 50% increase in overall capacity! did I do this math right or am I missing something.

a few questions before I pop these into my motorhome. 

1.  would you use your onboard inverter/ charger to charge these batteries, or would you run a separate stand alone charger for these?  I would like them to charge when I fire up my generator... which currently goes through my inverter chargers.  I currently have 2 magnum ms2000'S (one is newer and is lithium ready, the other is not).  Each one is capable of charging at 100 amps.  I think I would need to upgrade my remote in order to do this correctly?

2. Motorhome obviously has a motor and an alternator.... I have read that the Alternators can be overworked by these new LifFePO4 batteries?  Is this true or a myth... do I really need to worry about this?  In it's current setup, the alternator charges the chassis batteries (2 separate batteries) and also sends charge to the house batteries (not exactly sure if it does it all at once, or waits for the chassis to be topped off before it goes to the house batts)   

3.  If I use my inverter / chargers to charge these new batts, since the charge parameters are different... will that destroy my chassis batteries?  I am assuming when the gen is running and batteries are being charged, that it is also charging the chassis batteries.

4. I currently have no solar, but plan to add it down the road.  What type of panels should I be looking for, and how many panels should I be installing if the idea is to have these batteries topped off daily? 

If I'm missing something... please let me know.

Only thing would be capacity depends on how the batteries were rated. Some rate based on 20% depth of discharge, some rate based on the total cell capacity. To be safe, discharging below 20% should be avoided. 

 
Andrew did my RV (4) 200 ah (4) 200 watt panels and Victron charge controller. Super happy with the system & quality installation.
