I have this Lipo battery with built in protection and it's connected to this circuit. Connection at the top, left is battery charger and right is step up converter.
As a test I drew around 40mA from this until it died assuming that the built in circuitry would protect it. It promtly died and is now on charge via the micro USB connection on the left. However, when I measure the voltage on the battery it's just 600mV which means it's not charging!! I can bypass the protection circuitry but would prefer to be able to recover from this situation without resorting to such drastic measures. Anyone any suggestions?
