So, the BMS did not protect the battery? One cell failed due to low voltage disconnect? That is not good!!!
@@tsp2jxd It did protect the battery.
I had learned after charging up each battery, ... then you connect them all in parallel ... no load ... and let them sit for a day or two. This actually equalizes al four (in this case) to have the same voltages. THEN you make them up into series or series parallel... just sayin and I hope this helps.
I tested their regular 12V 100AH a while back and was very impressed with it.
Yes, I tested that one too. Very budget friendly, and seems to be pretty decent. Thanks
I have 2 of the full size 100ah ones from DJLBERMPW. Been running them daily for the past 6 months without issue. Would love the mini's but they were not out at the time i bought them. Got em for $166/ea which is a steal deal IMO.
Nice! Yeah, they seem pretty decent despite the low price. Thanks
❤Brad I’ve got two batteries that BMS went bad and was wondering if I can get one to replace them? And how did you get the tops off the battery, looks like they’re glued on pretty 😅good.
Where’d you get the battery screw caps from? They’re red and black too!!
Hi! Love your content. Buying 6 of these for my off grid. How would you wire 6 of them for a 24v system?
Greetings from sunny Jamaica 🇯🇲.I have a 24v system and I recently bought 4 of these 12v 100ah battery and I am wondering if I can connect them in series parallel to make a 24v battery bank.
I would say yes, but would be a good idea to put a battery balancer on them to optimize, charge, discharge and life of your new toys.
Greetings from sunny Jamaica 🇯🇲, thanks a lot much appreciated one more question what size balancer .
I noticed this brand of 50ah battery drops to 13.2v under load after charged. But it holds at 13.2v for a long time with about a 250 watt load. The 50ah lifepo4 battery from this company does 100ah load for a short period. Not a good idea to drain more than 50ah at a time under load with a 50ah battery. Seems to be a good battery with a good bms. However a 100ah battery will do a 100ah load drain safely. Will do a little more under power surge. Good Lifepo4 batteries.
Nice ill get one once my normal size 12v goes 😂 its heavy has like them round cells inside about maybe 30+ of it and its like 25 pounds.. when im done charging it from dead flat shut off it only gives me 92ah, before its was 95ah when new but i had it for like 2 years now kinda abuse it dead shut off flat couple times still going so its going to take me maybe 8+ more years to get my battery to a way lower capacity that ill need a new one 😂 but for 180 bucks for a mini is really tempting 😂 if they get that to 150$ it would be nice and then they can offer ones for 200$ with some fancy warmers and Bluetooth.. love the vids.. adding this to my cart 😅
Thanks Brad. 48V is the way to go for me. It looks like you need to have some kind of balancing going on between the batteries to run them in series like that?
I wish they fix up their website - AUD detected ok, added to cart ok, but can only ship to US? Weird that they do that when they, right at the get go, detected I was inquiring from Australia....very annoying.
@@Bennyboy-dog Get a US mail box address from Aeropost. They will forward it to Aus. for you.
Yeah, I've seen the balancers for this kind of series setup. I'm tempted to put these in service to determine how long they will work before going out of balance. If it's not very frequent you could easily top each off with a simple 12v charger. Thanks Ben!
I purchased one of these batteries and it worked great for 6 months and one day when it was fully charged halfway through a pot of coffee my inverter started chirping. The positive terminal was red hot in the battery was spewing hydrogen fluoride. I have a dog and four rabbits my home and we all know what it smells like now! The company told me they would give me a refund if I returned it so I drove an hour to The UPS Store, paid 40 some bucks and ship it back to them, then they wanted to give me a partial refund and then they want to test it to make sure it's not human error and now I'm out 250 bucks, and no battery! I would not recommend this battery to my enemies!
Temperature cutoff?
What tool are you using to remove the top? Any tips?
I show how I open these up here: ua-cam.com/video/ep__TSSQ5eU/v-deo.htmlsi=-vlbp_Gs6miTE7OF&t=416
what size breaker you use?
What battery charger are you using?

Nice😀Do you like the big "normal" size batteries better?
I like these smaller size batteries. Thanks
So, the BMS did not protect the battery? One cell hit low voltage diaconnect? That is not good!!!!
Yes the BMS did protect the battery. That's what it is supposed to do. Low voltage cell will cause the BMS to disconnect, that's perfectly normal.
@@BradCagle the normal practice is to set the BMS to fire BEFORE THE BATTERY to avoid exactly that situation. So, yes it protected the battery but the BMS should do that. It's not technically wrong but not best practice if possible to avoid it.
Carry on good sir!
@@tsp2jxd The BMS worked as it should. I think you're referring to the practice of shutting off the load before your BMS goes into a protection mode? Which I do agree. However this was a test so I actually wanted to hit BMS protection to make sure it works on these batteries. Thanks!
May I ask how long it took to be totally discharged?
The shunt said it would run for over 11hours at 450-475w. Now it did get hotter in the after noon so the power draw went up, I noticed this and turned it down as I didn't want to overload the inverter. I started the test early morning maybe around 8am, and it ended after 4pm I thing. So around 8 hours.
How long did the batteries run that 12000 btu AC?

@@BradCagle Thank you! Just the kind of info I was looking for.
What inverter did you use and what power watts??

The inverter in this video is a Victron Phoenix 1200/48 . See 5:58 and the next few seconds.
Read my Amazon 1st customer review on the 300ah variation from Dec. 2021
Doesn't exactly roll off the tongue, does it? :)
😅Nope LOL
I'm sure you've seen, but the reason they have these crazy names is so they can get it trademarked quickly. Once the name is trademarked as a brand Amazon will promote their products much more aggressively.
@@otm646 Interesting. Thanks
That discharge rate is low. .08C. Test it at a .2C rate and get back to me.
This is a real world scenario. What are you running off of a relatively small 5kWh bank where you're going to draw 0.2C? That's a kW continuous.
@@otm646 .2C on a 100ah battery is 20 amps that's the industry standard for deep cycle batteries. Discharged in a 5 hr time. Stress a battery to find it's true potential. I tested my same brand 300ah with a .36C discharge 109 amps. The BMS IN THE 100AH IS RATED TO 100 AMPS! Read a little before you comment next time.
Are the batteries made in China?
They are headquartered in Shenzhen China so probably are made in China I would think. Thanks
The point is it Preis corst
