Gauging battery level by voltage leads to disappointment.
You need to frequently re calibrate by load testing and then index that to voltage, but
this calibration doesnt last long.

An interesting statistic is that fully charged, a 12 volt battery is well over 12 volts.
In the case of lead acid chemistry, 12.5 volts is dangerously close to permanent damage to the battery and 12.0 volts you ARE doing permanent damage.
Technically a 12 volt lead acid battery is totally dead at 11.5 volts.

A 01.1 v change in a battery down at in that area is a MAJOR change, no matter what chemistry you are using.
When you get up around 40 volts, a tenth of a volt isnt so bad.

Other battery chemistries will have different numbers but similar situations.

Another thought, ALWAYS put a thermal circuit breaker in your battery pack to stop fires & explosions before they start as well as burn control.
