3. Battery bank wiring
Battery unbalance can be detected by looking at the midpoint voltage of a battery bank. If the midpoint voltage is monitored, it can be used to generate an alarm when it deviates beyond a certain value. Both a battery balancer and a battery monitor can generate a midpoint alarm. The BMV 702, BMV 712 and SmartShunt battery monitors all have a ...
What are the nominal voltage, open circuit voltage, termination voltage …
Midpoint voltage- the level at which the battery is at approximately 50% of the capacity is the midpoint voltage. This acts as a reference point when gauging the battery''s state of charge. For a 3.7V lithium-ion battery, the midpoint voltage can be around 3.6V.

Next to the basic display options, such as voltage, current and ampere-hours consumed, the BMV-700 series also displays state of charge, time to go, and power cons umption in Watts. The BMV-702 features an additional input which can be programmed to measure the voltage (of a second battery), battery temperature or midpoint voltage (see below).
Voltages | Li-Ion & LiPoly Batteries
Depending on the design and chemistry of your lithium cell, you may see them sold under different nominal "voltages". For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries. What this means is that the maximum voltage of the cell is 4.2v and that the "nominal" (average) voltage is 3.7V.As the battery is used, the voltage will drop lower and …

SmartBatterySense midpoint voltage monitoring
It only has two wires, so it can only measure one Voltage. You could connect it between negative and a middle point of a battery bank if the middle point is above 8V, so not good for a 12V battery bank for axample. This way, it would simply measure the Voltage betweeen negative and the middle point of a battery.

How serious is this mid-point voltage deviation and what to do
Period. Do you even HAVE a midpoint voltage? The only way you could is if you had 6v batteries in series. Do you? If yes, then one side is just not connected and reading 0v, while the other side is reading ~6v. Hence the (near) 100% deviation. If you do NOT have 6v batteries in series, you have a basic misunderstanding of what a midpoint ...
