    From 3s to 2s, got some questions

    So yesterday i asked if it is possible to remove a bad cell from lipo.
    People told me yes, it is, and it is very dangerous. Well my battery was a 3s 5000mah 25c.
    I have completed the procedure of removing 1 cell and do the rewiring. Everything went fine.
    Now my question is, If removing 1 of the cells from lipo does the MAH stays the same ? just a different voltage ?

    Are they wired is series or parallel.

    Series will double the voltage, parallel with double the Mah, i think............

    Correct. The pack should be reading about 8.4v when fully charged now if it's wired in series.

    well if i did everything correctly then i saved my self 30$... that was my idea to remove the bad cell and run my Emaxx with 4s 500 mah, before it was 5s 5000 mah... now, i wish nothing is going to happen to my esc by running this battery
