Most trucks can charge the battery on a camper pulled behind them.

I have 600a of 100a dc house batteries and they're working fine. I've never done a discharge test to determine their capacity though. I Use a 2000 watt pure sine inverter

Can these be stored inside the RV without a ventilated space?

Any recommendations on a pure sine wave inverter to pair with this?

Can you pair this with an old UPS for the inverter/charger portion.

Obviously need it to be safe and not burn down the house.
Please don't take my word for it and confirm on your own, but yes you can.

Most smaller UPS use 12V SLA batteries and larger models will use 24V SLA batteries.

On a smaller 12V model, you absolutely can just connect one of these up in place of the SLA battery and you'll be good to go. On a larger 24V UPS, you can connect these in series to get 24V and you're good there as well.

The charging profiles are a little different between SLA and LiFePO4 so it'll never charge the battery to 100% which isn't a bad thing. It's actually better for the battery over the long run to not always get to 100%. So you give up a tiny bit of capacity and end up with a battery that will last longer.

I have a bunch setup this was and we've been doing it in our business for years because we got tired of replacing SLA batteries all the time and wanted more capacity. Pretty simple upgrade to grab a UPS for next to nothing because it needs a new battery, connect one or two of these batteries and you've got a nice upgrade.

A few notes, if I'm mounting the battery externally like one of these would require, I'd add a fuse to the connection. Also, since a normal UPS is expecting a small battery, they don't tend to charge very fast. So it will take a really long time for the battery to get charged with the UPS. And between the different chemistry and capacity, any battery meter on the UPS won't mean a bunch and run time estimates that it may display will be wrong.

And finally, one thing I do especially on APC UPSs is disconnect the beeper. A lot of their UPSs will just beep all the time when on battery. So while it's open to get to the wires, I'll disconnect it at the same time.

Yes but you would want a sine wave one and limited by the size - if it is free probably worth it, otherwise get a dedicated inverter

I waited for a sale on the harbor freight Jupiter pure sine inverter. I got a 2000w as that would more than cover most of my needs. Someone said this battery has a max 100amp discharge rate. So if you need more powa' you would probably need to buy 2 batteries and put them in parallel. If you don't need the capacity you could go to a lower amp hour, and buy 2 cheaper. Make sure to find out the battery max discharge.

Good timing, the AGM in my van is officially dead. I need to swap out my ACR for a DC-DC charger but that shouldn't be too bad. Probably still a net weight savings too.

Quote from blueletterd :
That would require some heavy gauge to be routed all the way from the towing car, then have a beefy connector between, fuses... Sounds messy and expensive. Your best bet might be a roof solar panel.

Or, you may make the battery "mobile" and find a place in the towing car for it, and charge with a much shorter run of cables.
So, in most cases, with a 7 pin connector, your tow vehicle alternator does charge your trailer battery while the vehicle is on. I think what he is asking is, will the voltage be high enough to charge this battery. In most cases, it will be. the other question you need to ask is if your trailers on board charger while on shore power setup correctly foe this type of battery.

Can this be used as a replacement battery in a Ryobi electric riding mower?
Potentially yes and the 1st gen. Mine is still trucking on the original 12v 100ah lead acids (4 in series for 48v). You could probably rig 4 of these in their place, but YMMV. If you have a newer model then the battery tech is different.

So if it tried to use this with a inverter like a self contained solar generator would this be like a ecoflow delta 2?

Can you put multiple of these in series or parallel to be a backup home battery? Novice here, any expertise/insight would be appreciated.
