These have bee around a coupe of years now. I will wait for the price drop bound to happen. It’s easy to afford the newest technologies when some one else is footing the bill.
Not that I wouldn’t like to replace the starting battery in my boat with one- it just pooped out last weekend after 7 faithful years of service. The on board charger is on again this morning, at full charge, for the 3rd time since I used it last weekend. Surely a sign it is done.
