Hi All Im wondering about a few things as we are talking batteries.
1. how do people feel about the amphenol battery connector vs lugs? A lot of batteries are going that way. Lots to like about them. 2. battery cable lengths. I see both things said, that they have to be the same length or doesn’t matter. I did a large fortress system that they wouldn’t warranty unless equal lengths. Mind you, it would have added about 200’ of 4/0. I convinced them by using different wire sizes to make the % VD the same and they agreed. 3. battery lifting attachment points. 300# is really heavy and is it actually more than 2 people can do via OSHA? What about some threaded holes for lifting rings, or places for straps on the side?
