It depends on how you connect the batteries. If you connect the negative of battery one to the positive of battery 2, the negative of battery 2 to the positive of battery 3 the negative of battery 3 to the positive of battery 4 then the positive of battery 1 and the negative of battery 4 will give you 48v 7AH. (This is known as connecting in series.)

If you connect the four positives together. Connect the 4 negatives together it will give you 12v 28 AH. (This is known as parallel connection.)

If you connect the negative of battery 1 to the positive of battery 2. Connect the negative of battery 3 to the positive of battery 4. Connect the positive of battery 1 to the positive of battery 3 and the negative of battery 2 to the negative of battery 4. You'll get 24v 14AH from the connection of the positive of battery 1 and battery 3, and the negative of battery 2 to battery 4. (This is known as series parallel connection)

### I have a aowa electric bike 48v 500w. the batteries are split into 4 12v 12ah. can i use a lower, lets say 12v 10ah battery or lets say 4 12v 9ah batteries?

yes, the ah has to do with the capacity of the batteries, so the lower the ah the shorter the runtime, and if you have 3 10ah and 1 6ah the capacity of the 10ah batteries will be downgraded to 6ah

### E300 electric scooter battery,

The scooter uses batteries specifically designed for deep discharge applications. If your new batteries are not lasting then they may only be suitable for standby or backup type applications like for your house alarm system or garage door opener when the mains power goes out.

### How do I know when I need to replace the battery

The only thing you will look out for is the specs of the battery. That is the voltage that it gives out. The size usually determines the hours it can provide power on a full charge.
