I bought this battery half a year ago when it was $127 on sale and it's been great. It has a very compact size compared to other 12 volt 100 ah batteries.

Even the folding handles are a nice touch compared to a fabric strap that my other batteries have.

It's pretty insane you can get a battery like this for less than $100 now.

Can you tell me what you do with it exactly?

Various mobile party activities...

Use a 1000 watt AC Inverter to run both a 4k laser projector (JMGO N1 Ultra) and a blower for a 21 ft projection screen.

Connect 3 bass tubes simultaneously (Two, 12in and one 8in) to even out sound from other 15 in monitors I have. The bass tubes have their own amps built-in and are branded Rockville.

Use a 700watt Fog machine off that 1000watt inverter by itself once in awhile too.

I'm not using it for a trolling motor or solar semi off-grid continuous use.

There's a video on YouTube that convinced me... I'll try to find it.

Try this one:
https://www.aliexpress.us/item/32...45373.html

280Ah / $236.13 after coupon CD25US with Bluetooth, 200A BMS and low temp cutoff.
$0.84 per Ah after coupon. More money but more battery, more features and cheaper per Ah. Same brand.

I did just post this but the mods usually take down any posts that aren't from them so here ya' go.

Edit: and this one is dead anyway.

Good luck with that. The cashback sites have a terrible time getting money from AliExpress for that. 3 times mine vanished.Confused

5491, this is 1138. Yes, I'm seeing the same.

I figured it out. Using the OPs first coupon for 9 bucks off, then another $16 coupon from ALIExpress, so then you get to the OPs price. Got it.

EDIT: Above is wrong, only one coupon on this one. See my post below.

I never count on getting cash back as part of my purchase decision, other than a few retailers I have a 100% success rate with. But yeah, I have an AliExpress order with 20% CB from around Black Friday which is paying out.

I think the issues arise when people buy items through resellers on AliExpress, which the popular CB site excludes. If you buy from direct stores like Eco-worthy and take the normal cash back site precautions, I think it's worth the few seconds it takes to click through.
