A drop-in solution will eventually appear. It's no secret that there are at least three separate parties developing a drop-in solution. I'm one of them, but that project has been on hold for... several years now. I just keep finding myself busy all the time. I suspect Peter and Isaac's lithium solution isn't too far over the horizon, but I won't put words in their mouths. FYI: I will still release Linsight regardless of any other solutions, I just don't know when that will be. Now that everyone seems set on LTO cells, it seems like the last remaining puzzle piece is to sit down and write up all the firmware. No idea when that will happen.
