Battery always full when power c9meing in

How is it functioning so far now 2mos passed?

I bought two of those a few months ago. They've worked great for me. They do drain slightly with the Bluetooth being on constantly.

your fresh air return should be getting the colder air from outside which should improve the performance of the heater imho

Does this have an automatic transfer switch? Looking for a good 2k watt inverter for my camper that can automatically switch off when I plug into shore power.

Desulfication on a LFP?????

Connect the negative first, always in everything, even a meter

I have this same battery happy to know it has low temperature protection it didn't say anything in the paperwork. Thank you.

Another informative video thank you. FYI those bolts are brass not copper. I don't think a copper bolts would last very long. Keep them coming sir. And this and the Elfhub look exactly like the Pupvwmhb batteries I have been buying.

This is some very exciting stuff to see, im just about to get a 24v system built using 4 290AH smart Chins Lifepo4 12v batteries with Bluetooth, and heaters. Going with all Victron components except an Inverter for the time being, and it's nice to see basically my same build incorporating a balancer, and shunt ect, now I am curious, though do you have any for of battery temperature sensor? Like a Battery Smart Sense from Victron? I originally had got my Smart Shunt with the plan to use a temperature sensor on it, but after doing more digging, and realizing that the gray wire can be used for Voltage deviation, opposed to just a second battery system entirely, which im not using, or the temp sensor.. Knowing my main batteries are 12v themselves, the system keeping them balanced is a big thing, as well as being able to monitor it. So I'm looking into the Bluetooth temp/ smart sense by victron.

Nice work, my motorcycle lithium battery is dead. And the lithium charger show errir 0-1. I try this metod.

try the shop Smith when the battery is cool

EB3A can take a max of solar 200watts.

I have 2 fresh out of the box litime 100AH 12V smart batteries, I looked at them while waiting for the hasito battery charger. It arrived and to test drive the charger I put it on my dr preper lifpo with same basic info, the charger topped it off quick. I then attached the charger to the litime battery and get nothing, moved to other litime battery and once again..nothing. u think Chinese new year could be in progress, I've sent 3 messages and wait. I'm gonna try bumping one of them with the full charged DrPrepare battery

I am wondering if the bluetooth introduces a vampire drain. Great review, thanks!

You review the same class battery every time, you should go higher, like 200 or 300 amps!

As you say it seems to be identical to the previous battery you reviewed, with fantastic results. Once again, hopefully UK one day

Another good battery

Why are u on the floor

Say Bougerv three times fast.

Exactly the information and demonstration I was looking for. Great Job!

you could use it with only drinks like soda pop or beers or wine that would not be a health matter if that frigdge was used with what you tried. But not recommendable with food.

I would not take a chance with that technic specially with food. health is important. my experience i monitored my 20sq foot refrigirator freezer in the garage and it is a older model and the monitor showed after 24 hours the refrigirator freezer worked 8 hours out of the 24 hours. I plugged in my bluetti ac180 and added a 12,8v 100ah life po battery. worked well.

i have a pure sine wave 2,500watts invertor. i guess it will power my freezer but might eat up more ah than a 1500watt inveror?

I tested this same panel. Even with it on a good angle on a cloudless day, the best I could get was 67 watts. The amount of room you would need to set up multiples of this panel are pretty big. For me, I didn’t think they were worth it. Thanks for sharing your finding!

what size of fuse do you use?

What is the difference between the Lithium and Lifepo4 settings?

Does this charger charge 24v please?

Thank you,been looking for some back up,if apsortion is on 14,4- 14-or 13,8 and flot goes in, 13,5 is the flot rekomended,so wy go higher then 13,7-8,dont see a big differents ,like you,plus many people agre charge to 14,40 and down to 10%, make a differents in circles from 2000 - 6000, what I see you can use the batteri betwen 13,5 - 12,9 if you vont 6000 circ, of 100 amp batteri,you will have no more the 60 amp to use,we are fooled of the batteri industri,so to pay 1000$ for a 100amp batteri,is not much better the a good gel batteri, And you can keep your 230v charger plus the generator working,BUT, now we can buy kina litium witch I have 460amp litium 150 BMS, bloutouh, for1000$ to my door, the weight is of ofcourse a big plus !!😎

the pot makes a huge difference with the induction cook top. you need someting that is magnetic that pot is aluminum.

Like your videos. Please do a video of programming the battery capacity meter PZEM -015. Btw what is your setup for the laptop to monitor your test. Great videos.Thanks

Bought one a few months ago today I decided to look inside, and it's totally different from your I was shocked at the low quality design and components, i would recommend that anyone that owns one of these to take a look inside and compare it to yours and if its not the same don't leave it running unattended.

yeap you're right. great mind think alike. when i first got into solar, i set my float at 14. and boy i was wrong. when it reach float voltage it quickly shot up to 15v and shut down my power inverter. my cheap PMW charge controller couldn't handle and repeatedly reset it self off and on due to the massive voltage spike. now i have mine set on 13.7 and it works fine. really i need a better charge controller. between 13.5 to 13.7 is a good number. anything over that will cook the batteries over time. unless im trying to balance the cells.

I just recieved 2 li times smart batteries with bluetooth, right out of box i connected charger to either of them, i get nothing. I tried connecting a tiny inverter thinking if mite kick battery on. I get nothing. Im wondering if using App is non negotiable. Id rather not use app if possible.

Good review! It'll be great for my luch at work. I just ordered one.

Does this unit comes with a built in mppt?

Thank-You for this review. I recently purchased a Sourcepow and everything about that battery is identical to the Elfhub.

I was torn between this one and the mini version. Minn Kota says my trolling motor needs a 50amp breaker or fuse. I asked Watt Cycle on one of their videos which one I need and they were very helpful explaining the differences and that led me to buy the mini w/bluetooth.

I bought one. Online it says it charges at 15 amp but in the book it came with it says a continuous charge of 20?

Good review but a tear down, although destroys case, is always needed for a full review.

Comparing apples to oranges. What's the point?

Great demonstration and explanation. I have been procrastinating about getting one of these for about a year now and your little demo finally convinced me to get off my rear and get one.

Why not just use battery charger??😂😂

You got to open it up to really understand the build quality

That battery looks exactly the same as Elefast I have 2 of them I use them to keep my delta 3 pro running when I leave for a few days.

Oh, It's a battery.

Good review. The truth is, most of these BMS boards do NOT have over-current protection...they rely entirely on the over-temp protection to kick in, when the voltage output is too high for too long. That's dangerous, but also anyone using these types of batteries for sizable loads would be a fool to not have a proper breaker or fuse installed. Relying on the battery to save you from an over-current issue is just ignorant...a fuse or a breaker is the answer, not the $5 BMS board.

This is the best and safest performance I've seen, also at a fantastic price. No sign of it in the UK yet but will be very interested if it does become available

Would be interesting to see inside this battery to assess the build quality, cell and BMS manufacturer. You must have a ton of batteries laying around. How about sacrificing this one to see inside?

Excellent presention. Thank you. I really like your graphs showing the discharge rate and where things drop off. Nobody else is doing this, so thank you again. <grin> Seeing an actual graph of the voltage as capacity nears zero is very, very helpful. Not just for this specific battery but for LifePo4 in general. Most of my batteries don't have shunts on them or Bluetooth so I have to use voltage and the input/output watts to try to estimate where my batteries are at.
