I like the fact that I can exchange these batteries at any Interstate dealer if anything should go wrong, which is very unlikely, but just in case . . .
Hi Sue, Just me again. Say those batteries look like Alien Technology from a Roswell flying saucer crash site. I’ll bet they are on a par with Scotty’s dilithum crystals and could power a Federation Space Ship? Why such BIG batteries? Are these like the energizer everready bunny batteries, they just keep going and going and going…
Hi, Joe!
All my life it’s seems like I’ve been a day late and a dollar short. So when it comes to solar, I’m want BIG. A BIG 200 watt panel and a BIG set of batteries sitting on a BIG tow vehicle. (hmmm… and a tiny house . .. oh well).
