Hi Allan, A few questions.
how little energy? amp hrs night/avg. and is mx something this person does or would like to do without? But given what you’ve said, I wouldn’t go with wet cell industrial as you’ll never get the C rate you need. If the 8 x L-16’s have done her well ( and probably the battery box is set up for that form factor) and with your budget I’d go with another set of L-16’s flooded or sealed if the budget/want allows. And if the need is really quite small, I”d consider golf cart. Yea yea,I hear all the laughs, but where I live, golf carts seem to have the life they always have, but L-16’s ( all brands) seem to have a shorter and shorter life for reasons I don’t understand. jay peltz power > On Oct 22, 2015, at 11:19 AM, Allan Sindelar <[email protected]> wrote: > > I have a related question, please.
