I think the opposite end terminal format allows the current/chemical reaction to occur across the entire length of the plates instead of electrons taking the shortest path across the top of the plates when both terminals are at the same end causing more heating at the top of the cell. Also, it would be pretty hard to cause an accidental short by dropping metallic objects on top of the cells
Yes, the theory of that sounds interesting. There will be a minute delta in resistance along the length of the anode. I suppose the part closest to the terminal will see slightly more current flow than the bottom of the cell.
For long or high spaces this setup would work. You'd still need access to the sides so it's the width of the battery plus space to stick and arm in there and reach the endmost terminal. While it is more difficult to cause an accidental short in this type of setup, because we string them together in series, the potential for that is still there.
From Jack's EVTV video, he showed a cell emptying out completely out of electrolyte because they rest on their side. I think upright cells would "burp" but not necessarily spill out in those extreme cases. Do I remember correctly that Jack said it was 4 cells to each package (~12V)?
I like the terminals though. Having 4 screws on each terminal is a bear to assemble but it's not going anywhere once in place.
Not to take your thread too far off course, F16bmathis, but will your BMS take any action like discharging overcharged cells or bypassing charge current, etc? Personally, I don't see much of a point is spending time and money installing a BMS that tells you a cell is off but doesn't do anything about it. I read over quickly the link you sent above and that BMS does seem to action some, does it?
