Does anyone have any experience with 365Energy, they seemed to have popped up out of nowhere and is cheaper than ever Macer 12v 200a batteries?

Quite a bit of research later with absolutely nothing coming back on these batteries.
The plot thickens, these weigh a massive 14KG, most other 12V 200AH batteries are about 30KG, something smells off, but could be the capacity just isnt what they advertised.

The weight can be deceptive

Lets say a battery has 1st life cells
Ie lets say the pouches are 40ah the battery would be built with 4s5p ie 4 pack.in series with 5 parallel per pack

Now lets say the the packs have lost capacity and the battery is made up of 2nd life cells of 25ah then to get the same 200ah then you would need 4s8p ie in total 12extra pouches

So a first life battery can be much lighter than a 2nd life battery with same capacity

And 3rd party sellers on takealot are notoriously bad at specifications in listing
 
That is a possibility yes, but I had a look at other first life cells and they all roughly weigh the same, I doubt 50% capacity would be sold as second life, as the life expectancy would be extremely short looking at the tech sheets, they probably sell 70-80% cells as second life.

That said, would you take the risk on spending about R14K to get two batteries and capacity test them?
Even if you use 2x 200w loads it will take quite a while to properly capacity test them and you might miss the return window with takealot?

But that said, it very possibly could be accurate and I am just missing out on a good deal...Hence why I really want to know if some one tried these allready and have some rough capacity measurements :P

Even cheaper on BoB, only thing I see is that you can only connect 2 in series. So voltage wise great for a 24v system.

4x4community two posts claiming about 2/3 capacity on the 100Ah versions (both are by single post wonders so who knows..)

Linky

"I connected the battery after fully charging to my test rig that uses dump load resistors drawing 7 amps with cooling and a Victron monitor with shunt as well as computer connected for live recording.
The results show that the battery is able to give 63 Amps until it shuts down due to low voltage."
 
There are a crap tone of these batteries being dumped on the market at the moment.

From what I have seen, some are good and some are bad. Some batteries with the same labels are coming from different factories.

caveat emptor.

Rather get something with a warranty.

Thank you so so much that was exactly what I was looking for :) especially disassembled pics to see what it looks like inside... for safety

So if we say that his rig cables etc ... has a 5% loss, it would mean these are 65AH batteries, so the 200AH would be 120-130AH estimated

The posts claim that the 100ah version was available for R3000 on FBM so about R12000 if you want a 200ah-ish(2400WH) in series system (four parrelel), some specs on Takealot and Bob says they can do 4 in serial or parallel, OP in thread says 2...

Definitely not bad for the price, but there are 100AH 12V(1200WH) batteries out there for R6k or less.

That said the Mecer 200AH 12v batteries are also an option, but uses a much older chemistry, with a lower cycle rating cheapest ones I can find is about R6900 ish so you can make a 24v 200AH system(4800WH), which is a way more capacity.

Edit: I really wish there was some one locally that does power tests on all these batteries, there are tons of youtubers doing it for US battery makers and it helps a lot when picking a battery. I guess the costs would be quite a bit having to buy a each battery as I dont think any of the smaller manufacturers would sponsour or send their batteries for reviews.

The problem with chinese products they don't care for copyright

So you may find 2 or more products with the same sticker and different internals

Unless you do a check/capacity test on every single item you simply won't know

The fact that the weight got pointed out as a snag, may just mean next models arrive with a free bag of sand installed to meet the expectations

If you get a good supplier they may deliver consistent specs/quality

Especially if they know you know how to test and actually do quality control checks on shipments

Honestly even R3000 for 65AH it is not really any cheaper per AH than the 100AH Geewiz battery wingnut771 linked.

At least Geewiz has a reputation to keep up and are likely to honor the warranty, same with Mecer.
But these 365energy batteries are lying about the capacity right off the bat, what else are they lying about?
Their advertised cycle rating means jack now as they have already lied about the capacity.

Yeah, 60Ah works out to R5000 adjusted for 100Ah based on R3000 facebook price (or R7500 with TA price).

Hence why I said: "Definitely not bad for the price, but there are 100AH 12V(1200WH) batteries out there for R6k or less."

still do not know whether the cells are at least somewhat matched or what the BMS does. Unless really pressed on budget for something that should cope a bit better than lead acids with the charge/discharge cycle of load shedding I would not touch these.

I am inclined to trust the cycle rating of the Mecer way more than the fly-by-night newcomers but on any of these batteries the cycle rating is in essence meaningless. 1500/3000 cycles till what? Battery explodes/capacity zero/capacity reduces to x%? If, during month 23 of my 24 month warranty, I find that I now only have 50% capacity and the badly translated warranty indicated 60%, where do I find the supplier of my battery?

I (still) have a Mecer 200Ah and have no complaints but my sample of 1 does not mean too much either - for one thing as far as I know they now have prismatic cells and my unit still has - gasp, horror, roll eyes - pouch cells.

Ideally, if I have the option I would rather go for a 24V battery rather than series connect "dumb" batteries.

Overall, for the best compromise in terms of budget/value for money and some potential warranty support I would, as others pointed out, look for the ones that may care about reputational harm (i.e. the Geewiz, Mecer, Hubble, etc). @ScottulusMaximus [LiFePo4wer] might also be an option (at least has a 24V battery). Other option is to DIY (more risk on you) - google "Apexium".

yea the problem is even brands like mecer can be chinese home brands rebranded as mecer

i mean that is what some mecer inverters are just axperts rebranded as mecer
as long as they did their homework in sourcing it may be ok

many source products that aren't actually suited to our shedding conditions, ie just ups backup devices for markets where recharge time is irrelevant

many like to say chinese products are just crap, but forgetting that many of the "nice" brands are manufactured in china too
since we get high quality and low quality products coming out of china
many forget
they sell you what you want to buy, unfortunately most just look for the cheapest, hence we have the market flooded with what i would regard useless choices unless your load requirements are below 500wh/0.5kwh

what matters most for SA is the recharge time, and by the time you found a device that will meet your needs in this regard, you would have probably trimmed the list down to about 5-10% from where you started
