I have 4 x 12v batteries 7ah each. if i put these 4 batteries together . how many volt and AH would this be. please reply . thank you
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)
