How to Calculate Battery Life? (Battery Capacity mAh, Ah) 

Battery life and battery capacity is two different things, maybe you should get it strait

so what if the sticker is lost or has rub off like i have a ebike battery i know its 48v but idk what AH it is so how would i do this check?

Awesome 💯

(off topic) when making a three phase inverter using capacitors to balance legs and using a idler motor to ramp the 3 phase motor to running speed will having idle motor running in the wrong direction for the 3 phase motor will it damage the 3 phase motor or will the 3 phase motor just stop running once the idler motor is disconnected?

Excellent explanation of a question on what mAh or Ah or adding batteries in series or parallel provides to the user.

Useful.

What's the difference between cold cranking amps and Amp hours?

great!

This is indeed helpful, thank you.
