Ok Buddy Here we go !
First off I work on Golf carts where I work. The major down fall is even if you go 48 volt it still takes 6 batteries or 36 take 8 batteries.
The Weight alone is a Major down fall PLUS when thy go down thy go DOWN !
It is $600 to $800 for a set of batts !
Not a good out look on the deal in my book !
Nice thought but $ for $ not worth it in my book.
