Ping says he will build a flat pack to fit my box for a $5 upcharge, and that I will be able to mount the BMS remotely. If the BMS is mounted outside the box, does it need its own enclosure or is it weatherproof enough on its own. If it needs an enclosure, I might be able to put a window in the box to see the lights. Can I trust his BMS to keep the cells well balanced or should I still be monitoring cell voltages? The complaints about his packs seem to be regarding the BMS. I'm also a little confused about how his BMS works. If one cell was weak, would it be the one not lighting up or the one to light up first? I guess I like meters, warning lights scare me. I'm starting to lean more toward going this route, though for a first project. Emissions-free never responded to my e-mails, sent him three. I like the Headways but they will be harder to fit, if I go over 10ah. EVassemble has some pretty good prices on them, but are they a trustworthy vendor? I like that Li Ping has responded so quickly.
