Yep... people don't seem to realise those additional components needed add up fast.

A lot of people here seem to think that all-in-one units (like Bluetti, Ecoflow, Pecron, etc.) should be just barely over the bare-minimum price of the battery size they have inside them. Nevermind all those extra components like the solar charge controller(s), AC charger w/ UPS switchover, USB, DC out, etc.

Economies of scale. 100Ah is a much more common size battery, and they make many more of them. ..nevermind the fact that simply swapping 2 LFPs into a UPS isn't necessarily a great idea since the charge controllers aren't designed for LFPs..


These aren't suitable for use as a car battery, fwiw. Not great with high temps, can't be charged below freezing, and can't necessarily supply the large spike in amps a starter draws.

No need to wonder. Go to YouTube, plenty of reputable people doing capacity checks and teardown videos. These batteries are coming down in price because the technology is becoming more popular. I am also going to go out on a limb here and say they produce way more 100ah batteries than they do 10ah batteries.

I just bought a 1kwh EcoFlow power bank with a <10ms transfer time for $550. I actually thought of building my own with batteries like this first, but gave up after pricing out high performance inverters.

DIY is a good idea for large scale projects like a whole house backup system or maybe a van/RV but there's no economical way to make your own UPS yet.

I'm considering getting one of these for my trolling motor. How do I charge them? Can I use the same charger I use to charge my deep cycle battery?

pretty good price if you need this smaller 100ah capacity battery, but still slightly over 10 cents per wh before tax.

a recent 12v 150ah eco-worthy deal was ~9 cents per wh. i would rather wait for another deal under 9 cents per wh.

also, folks should consider that e-bay charges you on the full pre-discount code price, so you pay tax on $149.99, not tax on the $127.49 price. with the high sales tax where i live, this actually comes out to $129.57 plus tax per battery, a couple dollars more.

The only problem is that getting an inverter with a <10ms transfer time to pair with the batteries is still astronomically expensive.
Astronomically expensive is a bit much don't you think? River 3 plus $200, Xt60i cable $20, and a battery charger is $50. The equivalent UPS battery is going to be about as expensive and you'll have to replace the battery several times during this a LiFePO4's equivalent lifetime.

I mean, my car doesn't have the battery in the engine bay, and it's 20yrs old. It's not that uncommon.
I dunno, seems like charging would still be a problem.

The nice thing about most all-in-one units is that once you have one, you can buy inexpensive batteries like this and wire them into the solar input to expand their capacity. That's usually much cheaper vs buying their proprietary expansion batteries (albeit less tidy/convenient - you'd also have to find a way to charge the extra batteries, like using ecoflow's alternator charger for reverse charging).
It's it safe to use the 12v output cigarette lighter to pigtails to charge the extra battery through an EcoFlow power station?

The operating temperatures of this battery are 32F - 130F.
i see the operating temps now so not going to do it but arent these used around the house and in boats that can reach subzero temps?

You'd need some type of 12V DC charger in between to properly charge the LFP.
LFPs like ~14.6V, and most units' 12V output will be regulated around 12.4 - 13.6V

I have been using an ECO-WORTHY 12V 150Ah battery to charge a Jackery explorer V1000 power station. I purchased a DC8020 plug with pigtail cable and connect the two pigtail wires to the battery. It works well for me. The charging power is limited to about 100 watts (limited by the DC input current of the power station).

It's plug and play for a trolling motor. Just make sure you buy a lithium battery charger and not one meant for lead acid batteries.

anyone know if the posts can be swapped or upgraded to car terminals?
This can't tolerate the heat of an engine bay, and car starting batteries need more amps than this can handle

That is a lot of capacity for the money, but only 600W max output. Good setup for a router or other smaller electronics but it won't cover a single high end PC.

If you want >1000W it gets super expensive, standalone inverters with <10ms response times cost about as much as buying a power bank at that point.

You'd have to manually toggle the recharge though? I imagine just leaving the charger running constantly would destroy the batteries.

So you're not wrong... But you're not right either. The average home pc and server setup is not going to exceed 600 watts. You're talking about running a PC with a 4070+ at load. I'm guessing most people who want a battery backup are not doing it so that their game doesn't shutoff.
