Hello and thanks in advance to anyone willing to provide some input about my issue.
Ordered a new battery off Amazon called PUPVWMHB which is a 12V 100Amp Hour Bluetooth battery using a DGJBD BMS (Firmware Version 44, Device Name JBD-SP04S034-L4S-100A). I downloaded a few apps and am seeing some odd results for the current status of the battery. I have a LiFePO4 charger that I also bought off Amazon that can charge at a rated capacity of 20Amps. According to my charger the battery showed up almost at full charge (but I've been charging this things for about 4 hours now). Also this same charger did a great job on my 50Ah lithium battery so I at least know the charger works.
According to the charger the battery is charging at around 12.6Amps, and the App I downloaded says 12.2-12.4Amps so this is probably reading okay on both ends. The part that is scaring me a bit is that the BMS does not show that any balancing is on (Not sure if I understand exactly what this means as I've got only a single battery, but the battery has 4 cells in it). The Cells Read as follows Cell 1. 0.228v (fluctuates a bit up and down), Cell 2. 0.044v (Does not change at all and has had this reading the entire time charging), Cell 3. 2.61v-2.66v, Cell 4. 1.11-1.47. There are also two alarms showing the first being Cell Undervoltage Protection, and the second is Battery Undervoltage Protection. Should I simply let this thing charge overnight or am I dealing with a faulty battery here? Another question is since the two alarms are on, should I buy a pro-version of one of these apps and change a setting in the BMS?
