This is a decent price, but not the best one could expect. Last Fall I got one of these for $221 net of coupons. More recently, you could get this for around $240 net of coupons. I'm holding out for less than $230.

Hmm max off I'm getting when trying to apply 3DP30 is $25 off, and it redirects the coupon to be USLS25. 195.84 - 25 = 170.84
Is there a trick to getting the 3DP30 coupon to work?

The price of these LFP battery's keeps getting lower and lower. i remember paying like $800 for a 100ah like 5 years ago, but it was a Lion Energy. A couple buddy's run eco-worthy in their overland setup as a secondary battery. Seems like a slick deal.

I also encountered once, maybe something wrong with them, but I finally used the code on the next day morning, anyone can explain this?

These are decent batteries. Will Prowse did review on these with good feedback. They're on sale around this price point quite often. 4 of them make a good supplement 48v battery.

I'm not sure why you would buy these when EcoFlow residential UL listed(!) 100ah 12.8s have been available for basically the same price per kW/hr on and off the last several months. You get a more robust BMS with eco flow with additional protections, a 5-year warranty, but most importantly the cells have to meet EcoFlow standards. I bought 28, all under $100 before federal credit. 4x4 is the warrantable network, so if you need more power than that then yeah, they don't offer it, but otherwise, It's hard to justify eco worthy at similar price point per unit energy as a mainstream source like ecoflow

note that these might have the upgraded bms allowing 200 ah discharge vs the 150 ah rate on the older batteries, two of which I also got at a much lower price before the holidays, makes a difference if you are driving 4000 watt inverter at its max

I use two of these in my overland setup myself with 200w solar on top of my Dirtbox's RTT.

For me, the 280Ah is better than 100Ah. I just need 4 to make 48v, and get 280Ah out of it.

I bought this a few months ago a bit cheaper at Alibaba but keep getting my credit card hit with interest charges for .03-3.00 each month (4 months now). CC company say it is how they charge an international fee. I believe I used PayPal for payment. Awesome battery though.

If you used Paypal to pay via Credit Card on AliExpress, Aliexpress will try to process it as a cash advance, not a credit card purchase. As such, it typically charges a cash advance fee plus it begins charging interest immediately and PER DAY for the cash advance. I ran into this from a black Friday sale. The credit card company pointed the finger at AliExpress/Paypal and the way the processed it. AliExpress said it was an error and they were working to resolve it, but never did, and Paypal said everything processed correctly and denied my dispute after AliExpress did nothing.

You can search online for lots of other people running into this for over a year now, the theory is that AliExpress is trying to reduce their transaction fees. So, If you are going to buy on AliExpress in the future don't pay via paypal and a credit card.

Ugh, this is the only payment combo I do with AE since they are so sketchy with orders issues, returns, etc.

Who invents these list prices? This was never $1122, and who gives a hoot what list was, if comparable batteries are all in the sub $600 range, many substantially lower.
