Battery Monitoring FAQs

Q What voltage should I see from my battery?

A typical lead-acid battery will be around 12.6-12.8V when fully charged. You would not want it to drop any lower than 12.1-12.2V or the battery will start to become damaged.

Q How can I find out what percentage of my battery is left?
A You would need to use a shunt-based battery monitor with your battery's maximum capacity entered. This will allow it to work out how much charge is remaining in the battery.
Q Why does my lithium battery read 14.4V? 
A Due to the nature of lithium batteries, they will read much higher voltages than lead-acid batteries when fully charged. 14.4V will typically mean that your lithium battery is fully charged.
