# What happens when you put two batteries of different voltage in series with each other?

## What happens when you put two batteries of different voltage in series with each other?

This means that batteries have some internal resistance. Now, if you connect two batteries of different voltage in parallel current will flow from the higher voltage battery to the lower one. The current will be significantly high as the internal resistance is pretty low, which can lead to a spark while connecting.

Can you connect different amp hour batteries in series?

You cannot connect batteries of different amp-hours in series with good results. We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.

### Can you put batteries of different voltages in series?

Summary. In short, connecting batteries of different voltages in series will work, but damage will be done to both batteries during the discharge and recharge cycles. The more one is damaged, the more the other one will be damaged and both will need replacing long before needed.

Can you put two different amp hour batteries in parallel?

Connecting batteries of different voltage ratings in parallel is not possible. It will result in very large current flowing from battery of higher voltage rating to battery of lower voltage rating.

#### What happens to the current If two batteries are connected in series?

When batteries are connected in series the flow of electrons, as measured by the current, is the same anywhere in the circuit.

Can you parallel different voltage batteries?

You should not connect different batteries in parallel. If you do, the battery with the highest voltage will discharge into the other one, until they end up with equal voltages.

## Can I connect two batteries of different voltage in parallel?

Can you charge 2 12v batteries in series?

Series Batteries. Charging time will be the same as charging a single battery. Charge more than five batteries by connecting one 12-volt battery charger across each battery in the series, as if each battery were the only one being charged. Charge all the batteries at the same time.

### What happens if you connect two batteries together?

Plugging two batteries together creates an 18 volt supply and a short circuit. The current is only limited by the internal resistance of the batteries ( which is designed to be as low as pactical). Things are going to get hot and the batteries could leak and possibly catch fire.
