I have 2 Hubble batteries... An AM-2 and an AM-4 and both were delivered with firmware "issues"

The AM-2 was only charging to 91% and not further
The AM-4 was reporting 86AH instead of 100AH

After logging a support ticket with Hubble, I received the firmware updates for both batteries and both issues resolved immediately after the updates. Funnily enough, the AM-4 is reporting 110AH now... This is presumably the true capacity of the battery where 10% is kept as spare and is how they "allow" a 100% DOD

Hope this helps for anyone else experiencing similar issues

And what is your AM-2 reporting now in terms of Ah

My hubble AM2 was 78Ah, after firmware it went to 105ah. I called hubble and they said its meant to be 105ah. Somewhere someone is not telling the truth, because i bought my hubble AM2 as a 110ah

I have 2 AM-2 batteries, once is reporting 97.1 and the other 103.1, firmware update done, discharge and recharge done several times, made no difference.

Thats why I asked the OP what his capacity is now after the update.
Hubble sent me an update last week as well. I have no reason to update as my battery still has it's 110Ah capacity after 355 cycles. And yes, how can Hubble continue to sell and market a 5,5kW 110A/h battery when that is not what the customers are getting anymore.

100Ah... Checked on Inverter, via the logger and via ICM... I have discharged a good few times since updating and remains 100Ah perfectly.

As mentioned, I suspect their rational on marketing is that it is a 110Ah / 5.5kw but they lock of 10%... The fuzzy logic is then be honest and say you only allow to a 90% discharge

🤷‍♂️

The BMS shuts the battery down at 20% SOC. Only way to get around that is by disconnecting the Comms cable and setting the Inverter to USE or AGM mode with manual voltages. 
I have had 2 shutdowns at 20% over the last year. 
Unless they changed that to 10% shutdown with the new Firmware?

If you look at their brochure (https://www.hubblelithium.co.za/uploads/1/3/5/0/135079623/hubble_lithium_am-2_a4_pamphlet.pdf), it is marketed as a 100Ah and not 110ah... 

They are marketing the battery at 5.5kW and not 5.5kWh, so this opens up a new door / discussion.

5.5kW is the discharge rate and not the capacity of the battery (kWh) if we getting technical and using Google as the fact sounding board 🤣 (forgive me if it is incorrect). If this is the true, this is still false advertising as they market the battery as 1.0C discharge which is 100A and at 51v, that would equate to 5.1kW and not 5.5kW... So even then it is mis-representation.

If we consider that they meant it to be kWh, the same math would still apply and result in a capacity of 5.1kWh

Unfortunately no matter which way you look at it, their marketing is false.

I have not has this issue with my Sunsynk but have not tested it more than once down to 19% by accident. This value can be set on the Sunsynk however, so perhaps it is your Growatt with a safety setting, if you are able to override it by removing the comms

Nope. The Growatt I can set the shutdown to zero percent, the BMS still takes presedent in Li mode. The only way is to disconnect the comms and manually set voltages.
Not my intention as I don't mind the 20% shutdown for the sake of battery longevity. My battery is mostly between 30 and 40% before recharge starts in the morning

Interesting... As mentioned, I have not tested it more than once to 19% but I am sure an accident will happen some time in the future when we have a bad PV day or 3 during load shedding and I forget to adjust the settings to load shedding mode

The website states 5.5kWh.

Not sure what marketing calculation was used to get 5.5kWh.

The 20% BMS shutdown seems unusual - might be related to the Amp load on 1xAM2 at the time causing the shutdown.

I've programmed my inverter to switch to grid at 20% SoC.
If the grid is down, then use down to 5% SoC before inverter shutdown.
Not had the batteries shutdown yet - I do have 4 x AM2.

It happened early morning hours just before sunrise and the load was around 150W discharge from the Battery
This is my typical Battery usage during the night.

If you contact Hubble directly, they will send you the firmware and the program. They are very quick to respond

I ordered a cable from Diversified Solutions

I am not sure if the one from Solar Assistant works too as I have not tried it, but you could ask them

Many people have done the firmware upgrade with either their own made cable / a Hubble Lithium supplied cable or the SA cable:
You need a laptop.
