On a Witty Pi L3V7, with one battery but not another (and a good power source) the blue LED flashes quickly and constantly after finishing charging up. The web interface shows: Vout=5.13V, Iout=0.23A. The connected Raspberry Pi 4 is working OK. If I switch off the power source to the L3V7, the Raspberry Pi goes off as no power reaches it as the L3V7 has instantly cut the power. What is wrong?
