off grid solar, house batteries for rv, camper, boat. If you've got 12 V devices you can run that directly from the battery without any inverter which is nice.
I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.

Lol. These were NEVER $1,055. These "sale" prices are ridiculous. Like it's still a good deal. I bought two of these at ~$300 each last year and love them, but please they need to stop saying they're marking it down 75%!

No. These are NOT starter batteries. That isn't how it works.

Neither of the promo codes are working for me. I'll check on desktop later, maybe it's a mobile browser thing

$305 on ebay w/coupon code

It says 305 on one of the pics but right now it comes to 329 after a 110 coupon is applied. Even at the 4 pack option price isnt going down to 305 per unit. Maybe it fluctuates from day to day

can i use this to charge my ecoflow power station?

Im thinking of connecting it using alligator clips from 12v batt to xt60 to the back of the power station. not sure if this will work and advisable.
Yes, but use a XT60i connector. The XT60 limits the amps to 8 amps (car charger level).
With the XT60i, it will let you charge up to 15 amps, which would be 192 watts input (15amps x 12.8v). If you get 2, you can do a 24v setup and do up to 384 watts (depending on which ecoflow unit you have). You will need to buy a charger for the battery though made for LiFePo4 batteries.
I have a 100ah 12v battery with an XT60i connection hooked up to my river 3 plus and it charges at about 175 watts from the battery. I will be getting a 2nd battery soon to do 24v (River 3 Plus maxes out at 220v solar input).
Tons of you tube videos doing this.

I've got 3 of these, and 2 of the 150's
The 150's are on a food truck and we can generally run it all day on the refer units plus solar without having to run a generator, which is really nice. Charge them quickly with a plug in ac to DC 60 amp charger overnight.
I've bought 4 of the 280's for our bus conversion and had to return 1 because the Bluetooth wouldn't work and it wasn't registering a full state of charge with an ac to DC charger controller which made me real nervous. No issues with the return and repurchase. We run a diesel all winter and these are on a manual timer to fire up the glow plugs from 4:00 to 6:30 am so the bus is easy to start in -20ish weather. Works like a charm, mostly recharge off the solar but have to plug in occasionally.

promo code works but when you click on "Store Info"
Name:ECOWORTHY-US
StoreStore no.:1105115727
Location:China
Open since:Sep 8, 2025

you can also click to see all biz info, which is NOT the actual Eco-Worthy it's listed as;
xiamen tuo li electronic commerce co ltd

based off of this, it sounds like Eco-Worthy was stared by:
Xiamen Eco-Sources Technology Co. Ltd.,

can i replace this battery with my current 12v on my chevy Silverado?
No, starter batteries require far more cranking power (amps) to turn over a vehicle engine.

Can this replace a 12v deep cycle battery on my RV trailer?
Will it charge when I plug in the trailer to ac power?
Do I need to add anything?

You can run 4 of these in series for a 48V system. That's 14.3kWh for $1200 which is as cheap as it gets. You will need a few extras like a fuse and shut off switch, but all in about $1500.

No, it is not a simple drop-in conversion from FLA batteries. You may need a different charger/ converter, solar charge controller, and most likely some way to protect your campers alternator from burning out.

Yes, you can charge the Delta 2 with a 12.8V battery, but the unit will limit the input to about 102 watts. This is because, with a standard XT60 cable, the Delta 2 defaults to a protective 8A draw, assuming it might be connected to a car's auxiliary port. The port itself is capable of much more, supporting an input of 11–60V at up to 15A. To achieve the 500W maximum, you would need to use the XT60i cable connected to a higher voltage source. For example, a 51.2V, 100AH battery would allow the unit to draw to 15A to reach the full 500W.
