I'd read you bought the world supply of those hardcase packs.
Somehow, your bed looks softer than mine.
Someday, I may even get the charge card paid off for what I bought since last summer. I just kept having this nightmare where I was at the race, recharging for the main event, and the charger goes poof. So I wanted a big pile of batts.
Back to the thread subject. Answering itchyknackers question. I have permanently connected the power leads, but the balance leads are still seperate. This allows periodic checking to see if the pack needs balancing, and which cell if any needs individual balancing. If way off, you charge just that cell in the bad pack. If only a little off, you connect the jst balance paralell adapter and charge.
You could also paralell the balance wires permanent, but I like the idea of keeping the plugs intact at least, so you can check an individual pack.
Of course, you break in your lipo before cutting up stuff. No sending back packs with the wires cut.
My bad pack ratio just inproved. 26 packs, and only two stinkers.
Iv'e done the red to black discharge test on one of my 5s 20c packs. As LFP has said many times, the tabs act like a fuse. Now I have a new 4s pack. Thinking about running a bike light with the 1s pack that is left, if I can come up with a decent way to connect to a tab 1mm long. I'm thinking some kind of crimp, after scraping the plastic back.
