    Bad solder joints = Heat?

    Just wondering about something.....

    My Zippy 40c 5000Mah lipos were a bit warm when I pulled them from my AC MC last time I ran, or well, everytime I ran. The packs were about 115-118 degrees. I realized afterward that the soldering zippy did on the packs was sub par and I re-did the 5.5mm bullitts. Just wondering if bad soldering can actually cause the packs to run warm.

    On a side note, I figured 200amp discharge packs on a 60amp ESC and 1800kv motor would not even get warm. And yes, the bad solder connections were getting pretty HOT.

    Thoughts?

    The actual solder joints will get warm, as they have a high resistance, so dissipate more power (in the form of heat).

    However, bad solder joints on the connectors will not cause the pack to get warm - only the actual soldering will get warm. If the pack is getting warm, it is because you are drawing a high current from it, and the packs internal resiatance is causing the heating.

    Shoot, I thought so. I read somewhere that some lipos need a few cycles before they come in to their own and perform the best. Any info on this? FYI - I never had this heat problem with Enerland packs.

    Hellow Chris

    LiPo's do not need to be cycled and perform excellent from day one.
