Have recently received the kit below.
Battery won’t charge and I can’t get 5v out of the powerboost charger.
Yellow charging light comes on. Red discharged light flickers very briefly when battery first attached.
Voltage across the battery is 4v when I put my meter across it (and nothing else) but falls to around 0.1v - 0.2v when connected to the charger.
Not sure if the charger or the battery is faulty. Need this urgently working for close of play on Tuesday if at all possible.
Ideas gratefully received - especially narrowing down whether this a problem with battery of Powerboost board. Thanks
