    It's only because it showed a full charge after 24 hours but then drained overnight that I thought it could be a temperature thing.

    I hope you solve your problem soon. Please do update so we can all learn from it.

    I know the sub zero temp can reduce battery capacity but it does not drain it like you described.

    If anything, to store charge or to maintain battery life for long use after not using a long time, it is advised by experts to drain battery to 20-30% and then put the battery in the fridge.

    If that's case the cold actually is good for the battery and not draining it.

    Have you replaced that wire yet, noodleman?
    I have. Only got it back today but hadon't to destroy the bb to get at the junction box :cry: . Doesn't seem to be lighting up the charge indicator when the wire is wiggled around. Although it's only on 50%charge already. Hoping it's because the dealer hasn't fully charged it rather than loss of charge. Hoping to have my faith in di2 restored :wink:
