On mobile so not going to be able to find it but the seller who gave the sample battery to powerforum lists it as using 18650 cells.

GREENRICH 4.96 KWH U-5000P LITHIUM BATTERY REVIEW AND GIVEAWAY

Hi Guys so here is another GIVE AWAY! We are busy with a test and review of the GREENRICH U-P5000 1.5C 4.96 kWh Lithium Battery Yes we will be giving one away to one lucky Power Forum Member in a Lucky Draw I will post details on how to qualify for this GIVE AWAY soon watch this space! Sponsored ...
powerforum.co.za powerforum.co.za

UP5000 16S21P= 336 Cells (46000mAh per cell)
The cell technology in the battery is LFP cylindrical high density cells which can do up to 2C
Voltage: 51.2v
Nominal capacity 96.6Ah
Max.Discharge Current 2) 150A
Click to expand...

So if we look at the numbers the typical specs for a 37200 LFP battery is 3.2v, 18A(3C) discharge and 6000mah

Voltage: 51.2v as above divided by 3.2v of an LFP equals exactly 16 cells so that looks like a match and rules out other chemistries at 3.6v, 3.7v and 2.4v.
If we divide the the listed cell count by 16 we get 21 which is still a match. So 16 cells in series and 21 strings in parallel.
If we multiply 21 cells by 4600mah we get 96.6Ah as in the data sheet.
21 x 4600mah cells at a 1.5C discharge rate gives us 144900ma or 144.9 Amp discharge at half the batteries rated spec. so pretty close to their rated max discharge rating and well withing battery spec.

This is from the seller that provided the battery:

www.elleyhillpower.co.za

Greenrich UP5000 (7500W | 4960Wh) Lithium-Iron Battery

Handle electricity surges because of 1.5C technology. (7.5 KW) DOD 95%. 1.5C Discharge. 5 years products warranty, 10 years performancewarranty. Compatible with all major inverter brands. Top Features: -Parallel Connection A fantastic feature for those wanting to expand their system at a later...
www.elleyhillpower.co.za www.elleyhillpower.co.za

"This battery consists of 288 cells (18650 batteries) with 16 in serial x 18 parallell (16S18P)."

But both the 3686 and the 5000 have the same details and spec sheet linked so WTF knows, and that's kinda the point....

5000 spec sheet: https://marcelssolar.co.za/wp-content/uploads/2022/04/U-P5000-宣传卡-2022-01-24.pdf
And here they cut off the fine print: https://investsolar.co.za/wp-content/uploads/2022/09/U-P5000-Lithium-Battery-2C.pdf

Also we have a lovely one post wonder which links to elleyhill which seems to be the importer: https://mybroadband.co.za/forum/threads/the-battery-thread-solar-inverter.1071211/post-29106226

I cannot find anything that says LiFePO4 anywhere.

I wonder how many of these new battery brands will be able to honour their 10 year warranty in 5-10 years from now.
Seriously considering BSL for my 1st setup, or Pylontech US range

As I said, dodgy marketing.
Click to expand...

18 x 18650 cells at 80% of their new capacity is only 51.8Ah if you use the biggest available so it must have been a smaller one than the one I used.

But I agree with you on it being the wild west at the moment. I'm hoping the power forum store tests of the batteries will enlighten us.

Assembled yes.

And so this doesn't just look like competitor bashing it should be noted their rackmount and upcoming AM-2PLUS and AM-10 are LiFePO.

After doing a ton of research into this, besides being patient and waiting for mine, I'd go with Shoto or Pylotech as they are vertically integrated making their own cells. Everyone else is buying cells and BMS and slapping them together in an enclosure, including me.

Honorary mentions to BSL Bat, freedom won and sunsynk.

Greenrich on the other hand... Some deceptive marketing there, they claiming the first 1.5C battery, But the UP-3686 is only 72Ah which works out to 100A max discharge, hardly a revelation: https://cdn.shopify.com/s/files/1/0538/4470/5457/files/Greenrich_3.68kW_Datasheet.pdf?v=1635848935

The UP-5000 on the other hand I had to spend ages digging around for the spec sheet: https://marcelssolar.co.za/wp-content/uploads/2022/04/U-P5000-宣传卡-2022-01-24.pdf

"Max.Discharge Current 150A"
"2)For better battery life cycles,we suggest discharge in 43A(0.5C @25℃)"

So yeah...

EDIT: fark me the Greenrich uses 18650 cells and no mention of LiFePO, just "Lithium-ion", so could be Lithium polymer! That's terrifying. And a perfect example of why C ratings tell you nothing, sure this'll discharge at 140A, once, and then it'll burn your house down.

Pretty sure these are 100% made in a Chinese white label wish.com shop. On one of the independent forums a member did a deep dive saw pictures of the Hubbles on a pallet.
From a marketing perspective, It's pretty amazing how people bought into a garbage chemistry thinking they were getting a premium product.
 
Interesting, I'll see if my FIL has any issues with his three Hubble AM-2's, our PylonTech US3000C's are going strong after nearly six months are still at 100% SOH. I do have them limited to 20% SOC unless there is no CoJ supply and we rarely draw a lot of kW from them though this is mainly since we only have a 3kVa inverter.

Thanks all for your comments.

I must say there was a lot of positive comments here on Hubble before I bought damn thing! Not blaming anyone.

Can someone please explain firmware update thing ? Rs what what cable so I can attempt to update.

What I have noticed with batteries is that they are giving me max of 2.5kw discharge form 100% SOC and once drained they charge up back to 100% pretty quickly which is an indication that they are not really at 100%

I've had the same issues. Its common issue, I've looked at my historical stats and its been issue from day 1 and got worse over time.
Switching from lithium to AGMV mode solved it. i need to upgrade the firmware apparently. But yea, not sure if I want to spend money on cloudlink, wanted to go for solar assistant instead.

I am disappointed thought, lots of complains everywhere facebook, mybb, powerforum, and some even from last year. No public comms from Hubble at all.
Click to expand...

Please share some details ?

Are you referring to chaning the batteries to AGMV then charging till 53,6Vdc until inverter cuts of charging solution, when you remove CAN cable?

I did try that though has not helped maybe I didn't do it correct?

3) Please input the Float, Bulk and equalization Voltage at 53,6Vdc.
4) Please set the Low Voltage to 44Vdc. I could not find this setting though on Sunsyc Inverter?
 
So far no issues with my AM-2 batteries. But only installed for 1 and a half months. So hoping it continues like this.

I have a relative with the same issue. He drained his batteries in no time. Did a test by turning the one battery off and monitor how long it takes to drain to set SOC. And he found the one that was giving issues this way.

They would also charge up extremely quick. So he has one Hubble that looks like its fubar. Sending it back to Hubble to assess.

Hubble also sent him the firmware and he updated the one Hubble that is not giving issues. Now he has a constant 100% SOC when the battery is fully charged. Not this 95-98,99% readings.

I am also happy with mine. No issues.

Please explain why this is "deceptive marketing"? What is deceptive about it?

They're pumping the 2C marketing saying the batteries are "a cut above the rest", are "unlike most batteries (as) this is high performing" and "have a much bigger power output compared to other 0.5C or 1C batteries", which goes beyond flowery marketing speak. This 2C is maximum discharge (which they don't specify the period on either), max continuous is lower, recommended lower still, and charge even lower. The "C" rating should be continuous not peak, so you can actually use the battery at that rating.

For example my 48V battery can do 400A discharge, you don't see marketing saying it's a 4C battery, because it's for 0.5s...

Marketing a battery on it's peak power as it's "C" rating AND not giving the time it can discharge at that is disingenuous.

2C? Even as you yourself stated, they claim 1.5C,and rightfully so:

2C everywhere

3686
Max Discharge: "2C" for how long, no one knows
Continuous 116A (=1.6C)
Charging: 36A (=0.5C)


5000
Pulse discharge: 350A 100ms
Max continuous: 150A (1.5C)
Recommended continuous: 43A (0.5C)


The deception is that a C rating is for continuous, not peak, this is standard. They could MAYBE claim 1.5C but I highly doubt it'll sustain that current permanently but that's opinion.

You clearly have a different understanding of C rating to me :laugh:
