So far I have added:
1. Cell Monitoring wires from each cell (with X-Treme's permission) ending in a 24-pin connector to facilitate measuring all the cell voltages.
2. A locking Trunk (SHAD "50") mounted on the rear "rack".
3. A custom-designed Battery Fuse and Interconnect card has been built, to be installed as soon as I can "mount" it safely. It holds a fuse for each cell and provides a standard "power jack" for each cell to allow convenient use of a simple voltmeter to quickly measure the cell voltages.
I will post pictures and more details of each item soon.
Items #1 and #3 form the basis for a "poor-man's" BMS (Battery Monitoring System). With some thought, #3 could be used as a "manual" cell balancing system.
To maintain the Battery Warranty, the battery should only be charged with the supplied TS "smart" Charger. It appears to do a good job if the Pack's cells are reasonably balanced.
However, measuring cell voltages (specially with any unusually low impedance "crude" voltmeter) would tend to drain some (usually very small) amount of charge from the cell being measured. If one finds a cell that has become charged too much, say over 3.7 (or so) volts, just leaving the "crude" voltmeter on that cell for a while would tend to discharge that cell a little bit.
Obviously, if one used this "crude" type of voltmeter, one would want to be careful to not "measure" any one cell too long. However, while just making measurements, one might observe a cell's voltage dropping a bit. If that happened to help balance an out-of-balance pack, then so much for the good.
At least one can occasionally check for the potentially harmful "out-of-balance" condition, and, after gathering some cell "history" data, possibly even detect a "weak" cell.
