$165 100Ah LiFePO4 XZNY Ultra-Mini on Amazon

Looks like Thermal trip on the BMS not Current. 75°C thermal switch on the heat sink of the BMS of that battery. Thats what dropped out the first battery then came back on after cooling down. Overcurrent protection releases immediately after disconnecting loads. They use custom spec JBD style BMS. It will hold 120A until flat no problem. Cells can handle 500A+ Car audio guys pull 7-800A out of same cells. Good to see you included a low temp test. XZNY is an up and coming brand and continues to improve their products. Thanks for the video!

It seems like all of these "no name" batteries pass initial testing for capacity. What would be good to see would be the tests run again after 6-8 months of use to see if they degrade over time and use.

I would like to add to a previous comment about wearing at least safety glasses when working on batteries. Back in the 80's I had a battery explode right under my chin. The explosion blew me off my feet and the safety glasses off my head, blinded me for about 10 minutes, and lost my hearing for about an hour. In your test, the fact the BMS system did not trip until a much higher load would have been considered a failed test in my opinion. But as always, excellent job in your review.

open one up and lets see what's in side....

4:13 I can never thank you enough for the TPB references. Gets me every time 😂 🇨

You are missing one of the most important tests. Battery charge and discharge rate. This is important for building battery banks. If you conduct this test it should either have visual output such as graphing or a digital print out for comparison between batteries.

I've have one of their 12AH ones and its been solid.

“Overcurrent” seems just to be a temp sensor…

After I earned the nickname "Wrench Dropper" the only thing I really care about is short circuit protection.

Short circuit protection. When are you going to check a very important test???

There used to be a guy on youtube called K8MRD Radio Stuff, and he would have taken a dremel and claw hammer to one of those batteries. He might have even taken one to the range. Boy I miss him 🤣🤣

Just looked on Amazon. Current price is $229 each. Today I ordered 2 Lipuls mini's for $375.00 for the pair.

My son and I have four batteries from XZNY. Two of mine (18Ahs) are in a K8MRD copycat battery box. I haven’t put them through the torture test you have, but so far so good.

Getting closer and closer to my $1/ah price target before I buy. Patiently waiting.

No over-current protection; it got too hot and over-temp protection saved it. A lot of cheaper batteries are built this way. That's a hard fail, in my opinion. Fuse your wires appropriately and you can mitigate for that failure.

So what is inside these batteries? Is the build quality good. Can you look up the cell spec data? Are these grade A or B for what claim. Like you only did half the review on these batteries. Like we need to see the guys too.

A battery discharging at twice the rated current is a failure. I wish YouTubers would stop promoting this failure of the bms as a pass because it allows more current to flow than rated.

It's flying colors not flying carpets. No Alladins were harmed in this message. 😀

Great Batteries, I have several of thier 18ah batteries in my battery boxes (same size as a 12Ah SLA ) they are workhorses. Had them over a year now and no issues, used regularly for pota on my IC706 MKIIG. Each box has 2 batts for a total of 36Ah.

10 years ago, I paid 200 for a 10 AH LiFePO4.
