I'm currently getting quotes about an inverter/battery or inverter/battery/solar panel solution, and the two companies that have come back to me have offered either Dyness or Hubble batteries. I can't find much information directly comparing these two batteries, apart from the obvious specs.

What have people's experiences with these batteries been? What would you recommend?
 
Very happy with the Dyness A48100’s I got with my only annoyance being the hard shutdown at 15% built into the BMS which isn’t documented anywhere and was only confirmed after my suspicions and reaching out to them.

The only thing I may have changed would be going for 2 x F-7.5 Powerboxes instead of 3 x A48100’s but stock wasn’t an option at the time and I have no idea how pricing compares now.

In fact I would just do 2 x F-10’s if I did it over again now.

The Powerbox apparently can go down to 5% SOC without an issue or warranty concern.

The best option currently would probably be to go with what you can get the quickest. Lots of members here using both those options (I'm in team Hubble) and I don't think you can go wrong with either.

morning - I tried to find the number of charging cycles for both H and D. Only H reviewed its Cycle life at approx 3000? I thought that was quite low? No info at all from Dyness. Any info on this?

...sorry Im learning - what is NMC - LFP respectively?

Hubble AM-2 is NMC and if I am not mistaken, the new AM-5 is LFP. Having said that, if you are going with Sunsynk, you may as well also get the Sunsynk batteries. Inverter warranty is increased to 10 years and they seem to be good batteries overall.

You are right iro the Hubbles and sound advice re the Sunsynk as well as that is also a LFP battery which is generally regarded is the safest technology.
 
The benefit of NMC is the smaller form factor. LFP batteries of the same capacity are quite a bit bigger. But you get more cycles out of LFP...

Interesting, learning something new everyday. I didn't know there's much of a size difference between the Hubbles and for instance the Dyness ones.
 
I have seen some people having issues with Hubble.

Check on powerforum for some threads.
 
...the weight difference is quite big. Hubble AM-2 is 42 kg - Dyness BX51100 IS 50 kg.
the Hubble charge capacity is 3000 cycles - the Dyness does not provide any Cycle info.? One would think this is a standard info selling batteries of this kind. ?
 
I've got two Hubble AM5's which are LFP Prismatic Cells. 1C rating.

They're very heavy (50kg), but they seem to be working well (only a month in).

1 is running happily on my Victron and another on a Growatt.

NMC higher charge and discharge rates at the expense of charge cycles

LFP will give you almost double the number of cycles but the typical 0.5C discharge rate can be limiting if you can't afford a sufficient number of batteries in order to supply the inverter up to its full power rating

There are also LFPs with 1C and 1.5C

The a48100 states 6000 cycles at 90% dod

With NMC a 5 kWh battery can supply 5 kW to the inverter for 1 hour

A 5 kW LFP can only give 2.5 kW but 2 hours.

So to run a 5 kW inverter at full tilt you will need 2 of them

Get the LFP if you can afford it

That is not always the case, there are a number of 1C LFP batteries available.

Yeah it's a consideration if space is an issue.

Here's Snyper's Hubble compared to my Dyness (sorry it's the only 2 pics I could quickly find on the forum). The inverter would be the point of reference...

So I can get the Mecer SOL-B-L-M5 4.8kWh Lithium Battery for about R25k
Or the Hubble AM-5 at R33k.
Or Hubble AM-2 at R29k
I understand that the Mecer (Dyness?) is 4.8KWh and the Hubble AM-5 is 5,12KWh and the Hubble AM-2 is 5,5kwh (but AM-2 is NMC), does this make a huge difference?

Yes. NMC is better suited to cars due to its higher density, not houses where you want long life and safety. Almost no one makes NMC batteries for home use. LG was the last and they had to stop because they kept catching fire.
