Hi all,
I'm looking for a diagram of a battery charge equalizer. To be more clear, I have two 12 V batteries connected:???: in serie that I would like to charge equally because I heard that sometimes a charge difference can have a negative effect on the battery life.:???:
Can anyone assist me with a diagram or any other idea, I would appreciate?
Thanks in advance!
 

Welcome, if the batteries that you want to charge are of the same voltage and of the same power then there is no problem.
Le us assume that the batteries are 12V, so if you connect them in series it will be 24V. To charge the 24V battery, just make a battery charger of 24Vx1.18, it will safely charge the battery.
It is better to buy batteries of the same make.

Thanx Ugu Reginald!
Another question: I heard that it happens that "one of the batteries charges faster than the other, likely even if they are same made" can this be possible? would you please assist with a diagram of a charger of such ?
Thanx again for your help.
 

If two batteries are of the same voltage rating and of the same Ah, and from the same manufacturer and they are connected in series, they will definitely be fully charged at the same time (charge at the same rate).

You know in series connection, the same current flows in the two batteries.

One can be fully charged before the other if one of the batteries is faulty or it is an old battery.
