Hi,
Was hoping someone could assist with configuring my classic 150 to charge the Narada Carbon Lead batteries. I was looking at the 2v 960ah batteries. Battery specifications i found is as per link.

My system will be a 12v one so 6x2v batteries in series.
Any help on correct configuration would be greatly appreciated.
Cheers
Why are you planning such a HUGE 12v system ?, why not 24 or 48V with much more common sized batteries (more affordable)
The chart that is NOTICEABLY MISSING is Cycles vs Depth of discharge
Are these batteries sealed or flooded, I see a cap on it, but sales sheet says nothing about SG, electrolyte capacity
To charge, you are going to want 100A or so.
Hi,
Thanks for your response. 960ah isn’t that huge for 12v. I don’t draw large amounts of power in short periods of time. It’s more for moderate amounts over long periods of time so I need the capacity. Yes I could go to 24v but that would mean changing inverters and a whole heap of other components. This system isn’t for racing it’s more in it for the marathon.
I have two classics at the moment on my system so on a good day between them they push out about 150amp. Currently they charge a bank of agm batteries but they are starting to get tired.
The Carbon Lead batteries are fully sealed maintenance free. As far as cycle life vs DoD it is 7000 cycles at 30% DoD.

Any information on setting the classic 150 parameters for this type of battery would be much appreciated.
Since they are sealed AGM, I suspect any AGM settings would be appropriate, no EQ cycle, be sure that stays off.
Sometimes AGM batteries have a refreshing charge or something like a heavy duty absorb, but you don't want them to build up pressure and heat up.
Likely the settings you currently have , should be OK
Many thanks for your reply.
Those batteries from Australia are the Japaneses Sacred Sun lead carbon. They can be charged using the AGM settings. They will be charged quicker not because they take a higher current but because they are more efficient.
Do not equalize at any higher voltage than 28.8 on a 24 volt system, or 57.6 on the 48 nominal system, but once a month do an extra long charge of 4 to 5 hours for best life.
I have been working with these for a couple years, much superior to AGM, 60% depth of discharge. Just do not use below -15C.
