Ton618, Sweet find!
I was thinking it would be some time before used LiFePO4 batteries find there way to
Facebook marketplace so I could try them out, at $175 the fun could start soon.(unless they are charging $100 for shipping)

No worries at all

That's what worries me
That, and no low temp charging cutoff
Still, for the price I'd give it a try if I needed a 12v battery

Seems unbelievable.

Better get busy to complete 15,000 cycles during the 5 year warranty. ?

 

[Rednecktek]

That's only 8.2 discharges a day, what's the trouble? ?

Free shipping.

Agreed. I don't believe in the warranty either. I'll verify capacity, Bluetooth functionality and the ability to do a ~100 amp continuous discharge.

I've sent the seller a few questions (regarding the Android app, max charging and discharging current) to test their responsiveness.

I took a chance on the battery because of the Bluetooth connectivity. It is for small projects I am tinkering with. It will save me from needing to connect a shunt and the Victron shunt I was going to buy costs almost as much as this battery.

Seller responded within 90 minutes and answered each of my questions.

"Happy New Year, you can go to Google Play to download the corresponding app (there is a QR code in the manual that can be scanned); Maximum discharge current of 100A (continuous discharge within 80A is recommended); The maximum charging current is 100A (recommended charging current is 20-50A)."

Looking at the amazon listing I saw that one of their picture panels said "Do not mix ELEFAST batteries with other brands...." so I did a quick search on 'ELEFAST' within Amazon. That brought up a listing for the same 12v 100Ah battery under a different brand name. In fact the bluetooth optioned battery shows up for $165.99 but under yet another brand name, 'FEENCE.' Only rated for 8000 cycles though... darn.

Gotta thank Amazon for bringing a new dimension to the old axiom "buyer beware." On the other hand, I hope this signals the start of 2024's free-falling LiFePO battery prices

Any cheaper and one could buy these just to rip them open and harvest the cells.

Seems I saw a Will Prowse video on the elefast/feence. Almost went that route but the Aolithium was cheaper at the time, but of course what I choose is no longer available.

Can you post a link? I've seen the Aolithium videos, but not one for elefast or feence from Will.

I could only find this video from another Youtuber. Jump to 5:40 for a chuckle.

I received the battery today.

It came via FedEx from CA. It looks like the box had prior shipping damage which was covered over with tape.

The there was a little over an inch and a half of padding around the battery. Easily the poorest packaging of any 100AH battery that I’ve personally received. Still, in my case it was adequate, and the battery appears to be undamaged.

The battery came with two brass M8x12 bolts. A 12 mm bolt is too short and there was no flat or lock washers. I have spares, so that’s no problem.

The battery was at 13.1 volts when it arrived.

I topped it off with a 20 amp charger then started a 150 watt (~0.1C) discharge test.

For the Android Bluetooth app, I’m just using the XiaoXiangElectric app from the Google Play store. So far, the charge rate shown in the app matched my clamp meter. For discharge, the app also matches my clamp meter and the load tester.

More later...

$20 cheaper than my chins 12v is going for and it has bluetooth which my chins doesn't have so pretty cool if it tests out ok.

1 of the boxes my aolithium arrived in looked a bit like yours, must be a fed x thing.

Yes, but the damage was taped over.

I think it is more likely that the CA office for Elefast/Mehrpow taped over the damage from being shipped from China than FedEx taping over damage incurred from CA to my house.

 

[Ton618]

Throughout the load test, the Bluetooth app and my load tester stayed in agreement.

I am very happy with the 104 AH result!

It's sold out now
