Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

This has been an interesting thread to follow. Hats off to 2oldman for trying out the technology. I will continue to follow and watch the results and would also love to see real install pictures.
For what its worth, we both drive electric vehicles (2016 Nissan leaf with 30 KWH battery and a 2015 Smart ED cabrio with 18 KWH battery. We have found over the last couple of years that occasionally charging to 100 percent seems to bring back the last few percent of capacity. We normally charge to around 80 - 90 percent but every month or so we let it go to 100 percent as it seems this has some sort of positive effect on them. With the leaf I just put it on a DC fast charger downtown for an hour and it brings it to 100 quick. I am not up on why its good for them but I am told that it is.
We haven't noticed any degradation on the smart ED after over two years. We have only had the leaf since last year so no idea on degredation yet. The early leafs didn't like hot climates but they changed the chemistry in 2014 to a more heat tolerant formula so degradation is supposed to be slower. I would be interested in how you track degradation and your results over the long period.
Good luck with your project and keep us informed. I am a little jealous. :)
