120a BMS = 1440 watts output
Your math is flawed. A regular 100ah deep cycle has about 50 useable Amp hours & 90% of 150 is 135 useable Amp hours. so we have 135ah vs 50ah. which is far more than double the useable capacity. Its still closer to triple than just double. Besides A standard altrnator charges at 14.4 to 14.5 volts. LiFePo4 require 14.6 to get to 100% So a standard 12v vehicle alternator can charge this battery close to 95% SOC not 90% SOC. Lastly, charging current never just simply abruptly shuts off. The charging current will naturally slow down as a battery gets closer to full as the batteries resistance rises. This is why you can achieve 80% SOC lighting fast and the last 20% goes much slower. It doesn't just instantaneously go from full amperage to zero. Thats ridiculous. Thats just not how charging works. Do you people just make stuff up to sound like you know w.hat your talking about? Good lord. The amount of incorrect information I see here on SD is insane.

Good deal for the capacity. If an RV currently has lead acid batteries, is a DC to DC charger required to swap for these, or does the internal BMS take care of charging voltage issues?

Depends on how the current RV batteries are charged.

If they are charged directly from the RV alternator, then yes, you will need a DC-DC charger (unless your alternator is able to change charging profiles). The biggest concern is that the lithium batteries can draw a ton of amps when charging and abruptly shut off when full... This can burn out regular alternators.

If you have an intermediate charger (mine does) you could likely use that, even if it doesn't have a lithium profile. It will simply charge these to about 80-90% full. Even at 80% full, these will have almost double the usable capacity of a single 100Ah deep cycle

I just replaced my travel trailer batteries with lifepo4. I disconnected the the tow vehicle 12v/alternator charge wire from these batteries. My lithium batteries only now charge from the dedicated charge controller when connected to shore power. I then added a tiny 4ah sealed battery that takes care of my emergency breakeaway trailer brakes, which is only charged from the tow vehicle.

This was the cheapest solution I could come up with. In your scenario, the question to ask is whether you need alternator charging or not. In my scenario, I did not need to charge batteries going down the road, but I did need to ensure the emergency breakeaway brakes would still function (hence the 4ah battery, only connected to the breakeaway switch and the tow vehicle 12v power for charging).

In my research, a new DC to DC charge controller was too expensive of an upgrade for my old trailer.

Need DC to DC charger, most lithium needs a different voltage profile. Victron, renogy, ecoflow, ect make em. I would tax your alternator too much though. I like the Victron personally.

I'm installing multiple dashcams on my car to record in parking mode when the car is off. Can a battery like this be connected in line with the 12v car battery to extend the battery life?

Have one of these hooked up to my Ecoflow Delta 2 and it almost triples the capacity of it.
May grab another one to hook up to my River 3 Plus (or maybe hook them together to do a 24v battery).
I have a cheapie 2 amp LiFePo4 charger that keeps it topped up and use an XT60i cable to charge the Ecoflow. I have a 10 amp charger if I use a lot of the capacity and need to recharge it quicker.
Even having to buy a separate charger and connections, a heck of a lot cheaper than buying an extra Ecoflow battery. Sure I loose some of the convivence of the branded battery unit, but for the price, I have no issue with it.

How's the warranty and support on these? Is this a trustworthy company to deal with?

Inline? You mean parallel? No.
That's what the discussion about dc-dc chargers is about.
Connecting batteries of different chemistries in parallel is generally not recommended and most likely a bad idea.

Great deal though.

You mean during power outages? Sure... just need a way to charge it safely, and add an inverter to get 110V to run your fridge.

As long as you treat it like other batteries (with common sense) LiFePO4 batteries are very safe.

I own both. For some reason, the metal cased version is quite a bit larger. Look at the measurements. It's not just a little bit. It's a substantial size difference that only compounds if you are planning on using more than 1. The advantages of using metal don't make much sense. If it did, we'd see more manufactures using metal cases. The only 2 I see is DC House and ECO worthy, which are sister companies so it makes sense they both have a metal version, that happen to be exactly identical is dimensions. The DC house is rated at 165 and ecoflow is 150 but I'd bet they both use the same internal cells but DC house is using initial testing capacity which is always higher than actual capacity after the batter has been cycled a few dozen times. If you did capacity test on both, you'd find them to be identical.

'Inline' technically refers to series wiring. Inline meaning they are essentially wired in 1 continuous string or line. One break/failure anywhere in the string, you lose all power which is not true with parallel. With parallel, you can lose power to an individual battery and the rest of the batteries will function as normal. just minus the capacity of the down battery.
