Will has a new video out about Epoch 48V 30AH golf cart batteries. He seems impressed with the build quality.
I posted a question a few days ago about the high cost of shipping solar batteries --- $800 for a 5kWh EG4 battery from Signature Solar. I am also very concerned about how much it weighs (around a hundred pounds), because I'm an old guy by myself, and the only way I could get it out of my truck would be to spend another several hundred dollars on a scissor jack table like Will shows in some of his videos.
These golf cart batteries come in kits with all the cables you need to wire them in parallel. Four of them would give you 48V 120AH, and the shipping is only 120 bucks. And they only weigh 30 pounds apiece, so I could easily move them around without special equipment. They cost more per kWh, but I would save about $1500 in shipping and the jack table.
So, could I use three or four of these in parallel in place of one 48V 100AH solar battery? Would the SCC or whatever (I'm brand new to this) in a budget all-in-one converter like the EG4 3000EHV-48 be able to balance the charging and discharging on these?
The other thing that I noticed is that in the specs
it says that not only is the minimum charging temp 32 degrees F (0 degrees C), which I believe is normal for Lifepo batteries, but also the discharge and storage minimums are 32 F, while all the solar batteries I've seen go down to like -4 F. That would be a deal-breaker if true, but why would the same lithium-iron-phosphate chemistry have such a different low storage and discharge temperature?
Thanks for any advice.
