This one appears to also offer temp protection, fwiw.

> [Low-Temperature Charging Protection]
> The ECO-WORTHY 12V 100Ah lifepo4 battery has a built-in enhanced BMS with Low Temperature Protection, specifically designed for unparalleled performance in harsh cold conditions. Charging would be cut off to protect the battery when the surrounding temperature falls below -7 ° C ±5 ° C (19.4°F ±9°F). Charging resumes when the temperature returns to above 0°C (32°F). Ideal for cold winter use in RVs, cabins, off-grid installations and marine applications.

Exactly. Unless you want to save some money and don't really care about the battery info like a lead acid battery.
Is bluetooth going to tell you the voltage of each cell?

How is the reliability on these?

These seem cheaper than 100ah deep cycle Lead batteries now.

Anyone know of any good lithium options to replace 12v 5ah sla batteries in small UPS?

Good deal for a "dumb" 12v 100 ah battery.
I have been watching for a <$100 battery to pair with my current 12v 100 ah Eco Worthy to make a 24v setup.

Edit: getting error trying to pay, 2 cards have failed.

I have the same reliability question. One blog post I read suggested the cells themselves would probably outlast the BMS. They didn't think the BMS would last anywhere close to the full 10 years they often advertise for the battery. Don't know if that comment was based on data or just opinion. There is a lot of the later on this site.

Amazon has them. Just find the form factor you need and wait for a sale / coupon. I put a couple into an APC UPS and they have been working OK for a year or so. I have not tested the run time. AGM charging is compatible with LiFePO4, unless it tries to float charge, but the the BMS will protect the battery and cut off charging anyway. Once the voltage settles, the BMS usually resets.

A good deal without Bluetooth, but I really want that Bluetooth and would pay more for it at this point. I got one with and one without, and I'm already mad at myself for getting the dumb one. Flying blind on the state of charge is really frustrating.

So if I get two should I be using that cheap $10 blue pwm controller or get an mppt? Currently I have two 100w ecoworthy panels. Set it up for 24v or 12v?

Anyone been able to get the order to process? I have tried 3 different credit cards and it keeps getting errors. I purchased other items separately and they processed, so it is not the card.
