Lithium-ion battery pack 0 v or what is the likely cause of the low voltage?

1, whether single battery zero voltage, plug 2 short circuit, open circuit, and 3 plug connection is bad, lead and battery desoldering, virtual welding 4, inside the battery connection error, the connection between battery leakage welding, welding, sealing off 5, battery internal electronic components such as connection is not correct, 6 damage, battery by external short circuit or overcharge, reverse filling ( Mandatory discharge) 7, battery by the high rate of large current continuous overcharge, lead to battery pole core inflation, the positive direct contact with the short circuit. 8, battery internal short circuit, or micro short circuit, such as: is the cathode film have burr penetrating diaphragm paper contact short circuit, is negative electrode placed incorrectly, shorting plate contact or contact positive plate steel shell short circuit, the cathode material into the diaphragm paper, diaphragm paper itself is flawed, and the positive pole ear contact negative piece of short circuit.
