The batteries will last a lot longer if you do this. ....
How many amps is a "good heavy charge"?
I thought the OEM charger and my Mod Max48 are 15A chargers which doesn't seem like a "heavy" charge.
I'm building a custom carport for our cart and it could easily handle 2 5'x3' solar panels on a side or a larger one on each side.
I've seen an 8A 48V Genasun solar charge controller that works with 350W of solar panels - controller and (2) panels = $550 .
Would this take twice as long to fully charge compared to a 15A charger?
Just looking at pros/cons.
