In this case, would the setup only ever need a single 8 cell BMS, over each of the 8 parallel blocks (at least for 24V)? And if capacity is added at a later date, parallel these into the blocks and BMS requirement stays the same? I’m also curious what level of BMS could withstand the current...

Great explanation, and great links to resources - this is really helpful. 1) To ensure I've understood, it appears to me that you would recommend away from using a 16 cell setup for 24V due to the reason of ghosting, and instead all individual 24V packs should be built up in series only, each...

Hello, thanks for the responses! If I’ve understood correctly, one reply says not to string packs in series, the other says to do so. My understanding is the latter, Steve - can you explain why you would do series then parallel rather than parallel then series? In each configuration, what is...

Context 32 x 3.2V 280Ah LiFePO4 cells for a 28.6kWh bank, arranged for either: 24V 1,120Ah 48V 560Ah Max continuous load on this bank at any point in time is 4-5kW. Series/Parallel Guidance I've found here and elsewhere (incl. Will's videos!) say when constructing battery banks, the parallel...

Can anyone recommend 48V all in one charger inverters based on noise level?

So if something is rated as 48V, it's safe to have a bank rated at 51.2V hooked up to it? Is this a general thing or are inverters just a bit more flexible than other components?

51.2V - is it better to attach this 16S2P arrangement to a 48V inverter, or would 15S2P be healthier for it at dead on 48V nominal?

Quite right - but wouldn't it be 26.88kWh?

From all your comments, I think the only way this is viable is not to rely on daily charging (solar or otherwise) but to have a bank big enough to provide enough kWhs for each trip, and be able to be recharged fully between trips. smoothJoey referenced 3.2V 280Ah LiFePO4 cells by Xuba, 32 of...

How do people get around this problem?

Would this idea be possible with a hybrid 48V inverter/charger that acted as the MPPT controller? As far as I'm aware these only accept input (excluding mains) from 1 source (eg. solar) right?

I fear you may be right - this is definitely going to be the fallback option in this discovery.. I am indeed - this is where I could do with understanding what is feasible to pull from a vehicle's alternator. I don't want to be having to drive 18 hours a day just to keep the batteries charged...

Thanks for the response Ian :) All over UK when doing weekends, and looking to head into mainland Europe for longer stays. The plan (whether good or not is what I've come here to find out!) is to have enough capacity in batteries to hold for 2-3 days standard usage on a full charge (at not too...

Indeed, would reduce the amps flying around. Thanks for the suggestions as well in your longer answer - looking at the point on the alternator, how is it possible to achieve preferential charging?

Indeed! Thanks for your help - do you have any insight into the 6 questions above?
