Hi all,
So I'm looking at putting some massive power in my new rolling home and one of the possibilities I'm considering is using the batteries out of a Nissan Leaf... They have 24KWh of power per car and I figure that if I get a pack out of a wrecked car I'll have up to ~18KWh available if I use the whole pack (I'm still debating if I want/need this much, and if I want this much weight in the trailer). The cells are discussed here and look to be about 8.4lbs each and there are 48 prismatic modules in the whole pack, which is just over 400lbs of batteries, lol. I'm pretty sure that will be overkill for me and my needs, but the price is hard to beat for a power source that potent (the whole pack is ~$2-3000). There is a family installing this setup in an old GMC bus on youtube which is where I 'borrowed' the idea from. They have it set up with for a 48 volt system which if I used all the cells would most likely copy. For a 48V system this would give 375Ah, at 24V it would be 750Ah, and at 12V 1500Ah...
Previously I was looking at using some of the LiFePO4 batteries for my trailer, but given the layout of these cells, and the price point for the available power it seems like a simple choice. What do you all think? Any reason to not go with this kind of a setup? I also have a guy fairly local to me who tears the leaf packs apart and puts them in some smaller EV applications.
The plan for my setup at this point is to go with about 12-1300W solar (4 household panels with some mild solar tracking (still in the rough design stages)) and set the system up so I never have to plug in to charge. I'm actually thinking about not even installing a charger and just leave the system to be self sustaining from the solar alone. I would prolly go 48V for the battery and put in a 12V converter to provide for the trailer vow voltage system. Then install a nice big inverter that has high efficiency to power all the everyday goodies. Plus there are some A/C systems that run off 48 volts which may be interesting down the road
As always, thoughts and feedback are always appreciated!
