Haha, I already bought 4 of these.
By far the cheaper Lifepo4 ever. Less than .10 per wh.
Rated at 1920wh and I've tested 2 of them and got 1950wh.
Was going to post this but it seems I always get deleted everytime I post a deal.
These are not cranking batteries, they are designed to supply current at a somewhat steady rate. You would not want to use these type of batteries as your starting battery.
Description says 120A max continuous discharge x nominal 51.2v for your x4 series, so I come up with 6144w max output.

Working back from you numbers, it appears you might have been multiplying 12vx150ahx4 batteries to get that number and were referring to capacity?

In that case, multiply the 150ah x nominal 12.8v x 4 batteries for 7680w/h. Then multiply by inverter efficiency (check inverter, but 80% is conservative in most cases) to get usable capacity, which in this example would be 6144w/h

I put 4x 12.8V 100Ah in series into the Solar input on my Bluetti AC200P. It'll pull up to 600W (51.2V 12A) from the batteries to charge the internal battery. The power transfer capability on the AC200P is based on the voltage (current is max 12A, max power 700W) which is why I did 4 batteries in series. I use a pair of the P20 chargers to charge the external batteries.
Thanks, I'm new at this. Can't think of a better cheap way to add capacity to the cheap AC180s that were on here for under 330 a piece. Any better ideas welcome.
Any recommendations for a P20 charger?
Do you need battery balancing in there as well?

Obviously tech gets cheaper, but weren't 100AH lifepo4 batteries close to $1000 not 2 years ago?
Can a regular battery tender for a car charge these?

Anybody make a battery box with one of these? For car camping, running a fridge, small inverter, usb chargers etc.

Does anyone know what the surge current is before the BMS kicks in?

I want to run an 1800W inverter that has a 3000W surge current. So ~150A max constant/~250A surge. I'm not going to be regularly maxing it out, but I want to size a battery that can keep up with the inverter.
You would need one that has a higher surge rating or you would need two of these.

Frankly, Its cheaper to parallel two than to get a 300AH surge capable.

for a 12V backup sump, should be fine. You'll get loads of run time. I wouldn't use this for primary as you'd still need an inverter and a load switcher.

Interesting. I saw that deal and thought from the comments it was a hack that got fixed/shut down... but it seems it's still possible to get (I didn't actually order but it showed up in cart). $189 for that cool 800W charger is a lot more tempting than $600! I haven't looked into how it would pair with external batteries like this one, but for my use case (keeping a refrig running at ~110W), the 180W recharge rate I can get with my $12 cable is probably sufficient. (I thought about getting a 24V battery or running 2 in series to get 360W... but this deal seemed too good to pass up.)
If your paring with something like this, you do not want the ecoflow product.

The ecoflow product is a DC to DC step up converter. Its specifically designed to charge the ecoflow packs at a higher voltage.

You'd want a DC/DC charger, that will current limit (like a victron DC/DC). The purpose is to not overstrain the alternator. and to limit the amps to the battery.

I believe this easily fits a gr27 battery box, but will not fit a gr 24. The length is the same, but the width is about half. It would actually leave your box with enough space to have a plug in charger (though the heat build up might not be so good). You can also insulate it for winter use.

You theoretically need balancing in series circuits, but is not commonly done as each BMS will shut down the charging as it tops off.

Also if your charging as a 12V, you'd have 4 12V chargers, so each battery charges independently. If your charging at 48V, then you'd periodically top charge each of the batteries at 12v.

It also depends on how "quickly" you need to add power and what is the lowest your input will take. You can add input generally at 12v, but it will be at around 80-100W/hr rate.

Keep in mind, this battery holds about 1800-1900w of power. It is capable of being recharged at 100A , which is about 1400w so could in theory charge in about 1.5 hr.

So would if it has similar capacity at $189, but I am not seeing it. Do you have a link?
ecoflow is 189, 100AH, no bluetooth connectivity.

These are meant for this type of battery chemistry. There are different voltages for full, empty, float, etc. Plus some Noco/Tender are only 1.5-2amps charge since their goal is to keep lead acid alive when not in use, this one has a different charging profile. I am not expert, just from my research in past couple of days.

I have both, a Genius 10A. These are much cheaper, can do 24V 10A or 12V 20A. They have a fan, so noisier when operating. Not weather resistant like the Genius. I used 2x P20's on my 4x batteries in series, each on 24V. Seemed like a good way to charge a pair vs. having 4x chargers.

I don't think so when in series. Internal balancing should be handled by the BMS, but I'm kinda new to battery balancing.

Edit: As Madmax718 pointed out later in the thread, use a charger per battery in a series stack for balancing.
