6 FAQs about [Voltage drop from battery pack to device]

How much voltage drop does a battery have?

The amount of voltage drop depends on the battery’s chemistry and design. Some batteries are designed to handle a lot of current without much voltage drop. These are called high-discharge batteries. They have a lot of internal resistance but can provide more current for a longer period of time.

Is a battery voltage drop real?

So, the voltage drop is real — the measured voltage is what your load gets. The more current it draws from the battery, the lower is voltage it gets. When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load.

What voltage does a car battery drop when not connected?

Use the multimeter to make the measurement while the controller is connected if you can. A car battery has over 13V when not connected, yet drops to 10.5V while starting the engine. Which voltage is correct? Both. Just going to add a note. Some batteries, such as lithium ion, are pretty well modeled by the series resistance concept.

Why does battery voltage drop under load?

Why does a battery drop voltage if it's open or closed?

When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current when the measurement is being made (so at the terminals the voltage is indeed lower).

What happens if you plug in a battery pack?

If the circuitry in the battery pack contains a substrate diode from the communication line to VCC, it is possible to disrupt the VCC supply when plugging in the battery pack. This disruption may cause improper operation of the battery-pack electronics.
