Same here. I'm using a series pair as backup power for an ECO-FLOW Delta 3 Plus power station. I've also learned that the BMS within can be monitored/adjusted with the "Overkill Solar" app, a level of info depth and control beyond what the Eco-Worth app provides.

Also comes in at around $0.09/watt-hour

running mine in series as well and what a pain. they lose balance after one discharge. always getting pack over volt when hitting absorb voltage.
So here is your answer to that issue and it works great - ensures all batteries remain with the same level of charge and adjusts the charge as required - but it really does workhttps://www.amazon.com/Battery-Equalizer-Balancer-Supports-Trolling/dp/B0CLTZ2XQX/ref=mp_s_a_1_1_sspa?crid=QT5YU8EGF1F7&dib=eyJ2IjoiMSJ9.K36ZBwtm0L0BOnIm-MkW6e05dbt1iWMZP_R4cz46O1GpUAQrvxeNfdhflle-l26Y679y_iO0lUbfOaiPN35AKVT--YusdIiJ3u-3dj3QoCcNgdIUJvgGHBWxXU00eNY3TUd8kCF79lMqc8gB-OwxwOe_eNxIs9cll5NJNjsZN_g9E29MawMDJzgaMaFk8LKVf15synSG3f5nzfuQb3tcnA.F1R-hIKnGFgrG_T2lp7cpvLU1TavrlRc34OBfvr0kac&dib_tag=se&keywords=battery+balancer+lifepo4&qid=1760137401&sprefix=battery+balancer+%2Caps%2C158&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9zZWFyY2hfYXRm&psc=1

Using 4 of them. 1 on each set of 4s 12v batts and so far they work great. I still have 10ah--20ah differences according to the app during the day but after the day is over they are back to in balance.

I bought 4 of them 2 months ago and connected them to 1 of 2 of my lv6548 that run my house. Cycled them to about 50% every day for the last 40 days. So far so good. I think the price is too high compared to Rvpozwer but I haven't seen any breakdown vids or long term reviews of those.

How much did you pay for your Rvpozwer and where did you get it from?

Looking at how they sell for $136 on amazon, they likely cost 1/3rd of that:
https://www.amazon.com/Rvpozwer-L...B0F1TLL48V

The first unbranded battery here looks very similar. Since you have it on hand, do you agree?

Looking forward to your input nod

I chickened out and didn't buy it. I was looking for more reviews of it and I couldn't find any. Its $270-290 for the 300ah battery on eBay when its on sale. I got 30kwh of capacity so far for my house and I haven't run out of power yet. Here in Nor Cal we get a lot of sun but it's raining today so lets see if I run out of power tomorrow. I d/c the power back in April and haven't gone dark yet, but if I don't get any sun tomorrow I'm screwed.

I think the capacity is accurate but there's no blue tooth. I'd bet it uses an inferior bms as well.

Shouldn't be more than $280 if you buy 4. I'm going to wait until the drop to that to buy 4 more or I'll buy a different brand 300ah.

I messaged him to reduce price to 280/each for the 2 pack. He refused.
